The final update for OS X 10.8.

Overview

Apple OS X Mountain Lion is the latest release of the world's most advanced desktop operating system. Mountain Lion includes over 200 new features to update your Mac into the best computing experience yet.

Apple isn't taking pre sales yet, I'm not sure why MU is posting developer seeds like this, and not even labeling the main title as a beta (but instead making it sub text). this is misleading, someone might see the 99 dollar thing and think they are buying a retail lion that's expensive, and not and ADC membership and access to a beta with a ton of known issues still, not intended for consumer use. By no means was i confused on what it is, i always read the subtext and keep up with ADC anyways, but just stating as someone who also does mac tech support, the average user isn't going to read the subtext. heck, 23% of people infected with flashback haven't even run software update yet, certainly there are going to be a few mislead by this being on macupdate.

Hello, I am having trouble getting my macbook pro back up and running. I downloaded thinking it would help and I am not sure I am doing what I need or am suppose to. It has been a long time since I have worked with it and am not familiar like before. I am having multiple issues. I have tried restoring, creating images, erasing, partitioning and more. When I go to re-install Mountain Lion OS X it tells me to sign in with my Apple Id and then tells me the item is temporarily unavailable. i/o issues are also affecting my work. I am not sure where to begin. If someone could help out, it would be more than appreciated. Thanks

Oveall I think that Cougar has a lot of nice touches. I still miss Rosetta, and the drab Finder sidebar is atrocious (I find it harder to spot what I'm looking for than SL's sidebar) but overall it's a lot better than I expected. One thing I sorely miss, besides Rosetta, is the zero-out option in Disk Utility. With this option gone how are we supposed to write out bad sectors now?

Well, I took the plunge and upgraded my late 2011 MBP running OS X 10.7.5 to OS X 10.8.5. The App Store experience was not good as far as downloading goes, the download quit several times and an alert window popped up that gave an option to "retry". It took the better part of a day to get this beast downloaded (yes, I have broadband). As for the OS itself, I'm not so crazy about it. More bells and whistles, seems to me.

My pointers for OS system upgrades. These should be fairly obvious and logical, but surprisingly I see and hear of people who will try to run an upgrade, with 5 apps running, downloading files, and so on, then wonder/complain that the upgrade 'screwed up' my system. 1. Perform Verify Disk AND Repair Permissions BEFORE upgrade. 2. Boot from another partition or drive, other than the one being upgraded. This ensure the partition to be updated is completely accessible and no files are open or in use. In this day and age of inexpensive supersize hard drives, there's no reason not to have an extra partition to boot from for situations like this. It doesn't take much space. A bare bones install of Mountain Lion will fit on a 10 GB partition. What's 10GB on a 500 GB or 1 TB drive? Disconnect all other external drives/unmount other partitions, other than one you booted from and the one to be updated. 3. If unable to boot from another partition or drive (i.e. you are updating the same installation you booted from), then before starting the installation, shut down all apps, including any of the apps that run on the menu bar if you can. (us old Windows people will remember the old saying about quitting all TSR - Terminate and Stay Resident- programs before doing any Windows updates, this is kind of the same thing, turn off all those third party apps running in the background). Go have some coffee while the upgrade is in progress, really you don't need to be working at the same time, those 15 minutes are small compared to the time you will waste if the install goes bad. 4. Perform Verify Disk AND Repair Permissions AGAIN AFTER the upgrade finishes and the system reboots. 5. I run the Combo updater, even if I'm just upgrading from one point release to another. For newbies, Apple releases OS updates in two forms, 1) a smaller update that updates from the immediate prior release, like if you have 10.8.4 installed and want to upgrade to 10.8.5, and 2) a combo updater that updates any prior version. For example the 10.8.5 combo updater will update any version from 10.8.0, .1 , .2, .3 and .4. Why run the combo, even if just upgrading from the previous point release? There have been times when Apple has forgotten files in the point upgrade, and the point upgrade is based on just covering the delta between the two points releases. The combo makes no such assumptions and includes all files changed since the dot zero release, and during the upgrade, a simple date/time and version check tells the updater whether to copy over or not. When you consider that OS X has HUNDREDS of THOUSANDS of files, the possibility of human error in packaging when applying cumulative point release updates on top of each other is likely higher, versus a combo which makes no assumptions about what got changed in between. I do not have any proof of that, this is a personal opinion, I could be wrong, but in my experience I have had good results always using the combo. Besides if you read any of the Mac publications and tech pundits, nearly all of them recommend using the combo as well. If you have multiple Macs, or work in a multi Mac shop, it's also a lot simpler to keep one combo updater on hand, than multiple point updaters. Hopefully, if you follow these steps it will minimize the possibility of those spurious, hard to pin down, system hick ups that are often reported here. Lastly, laptop users with smaller drives that feel they can't afford to set aside 10 GB for a boot partition, invest in an external drive, it's well worth it. If you have a Time Machine drive, you can even partition off 10GB on that. Good Luck!

Apple need to fix Software Update. Every time I try to use it to update OSX it grinds slowly away for a short while and then gives up the ghost and declares a fault. I suspect that the Software Updater cannot handle the load on it. I find it is far faster to download updaters for OSX directly from the Apple download site.

Is it **just** me or is the Finder window zoom-to-fit function **still** broken in 10.8.5? I've been sending out feedback reports to Apple with regards to this particular issue (i.e. Finder windows DO NOT ZOOM properly when viewing contents in list-mode cmd-2) ever since 10.7, but oh my..this is getting lots of Apple M$-like love for the last couple of years now :/Other than that, pretty stable and all.

Very smooth update. Mountain Lion has been very fast and stable on my machine. The only exception—and this seems to only be related to my user login, and not others on this mac—is a very long wait after the desktop loads, before I can do anything. Several minutes at least. But since I unusually put it to sleep, that hasn't been a big issue. I'm guessing this is the last update until 10.9 Mavricks. It's been a fine ride so far. :)

The update went in but not so smoothly. I clicked the restart button and it restarted but after seeing the Apple logo I got a blank screen. I waited about 6 or 7 minutes and it still didn't resume the restart I just sat there with a blank screen. I finally did a "hard shutdown" and after i did I started my MacBook Air and it restarted and all appears just fine. I don't know why it did what it did but all appears to be OK.

Incredible number of problems, new ones every day, not limited to but especially in Mail, Calendar and Contacts and constantly if/when you are at work trying to use MS Exchange servers. Generally speaking it seems it is rarity if you report a bug (radar.apple.com) it gets fixed, especially in Mail/Calendar/Contacts. Reported bugs do get dismissed as "duplicates" of someone else's report and then not only are they not fixed, there is no visibility of them any longer. I have bug reports in the Apple reporting system that have been there since 2006, open, lingering.

Funny, 10.8.4's new qtkittrustedmoviesservice process does not appear at all in the list of What's New, but it appears in Activity Monitor every time I open any Finder window containing movie files using more than 100% of the CPU for a loooooong time. I'm not sure what this piece of shtako does, but it behave suspiciously similar to the QuickLook process that also used to crank up the CPU for an inordinate amount of time to make movie files QuickLook-able. I hope Apple dumps or better tunes this loser as soon as possible.

The update went extremely smoothly and I like the new version of Safari. I expected more for this release of ML and I agree that something should have been done about the "fuzzy icons" which are a pain at times. But on the whole this is a good update and I detect that Safari is running a little faster with this update or is it my imagination?

On all MacBooks, the ‘Empty Trash’ and ‘Secure Empty Trash’ commands should be separated because most people use the Trackpad to navigate the interface, but it’s VERY easy to accidentally select ‘Secure Empty Trash’ instead of ‘Empty Trash’ simply because your finger slipped, or more frequently because the Trackpad (especially the one on my current model) doesn’t detect fingertip heat/moisture with perfect accuracy or timeliness — and I’m a professor (not a brick layer), so my fingertips are not particularly thick, cold or dry. This is especially annoying when there are many files, very large files (like movies), or many large files in the Trash can, in which case ‘Secure Empty Trash’ takes a very long time to finish. And when you accidentally click ‘Secure Empty Trash’ and you want to click the “Stop’ icon so you can try again to select ‘Empty Trash’ so you don’t have to wait for the secure-empty process to finish, it frequently takes just as long for the OS to stop securely emptying the trash as it would to simply wait for the secure-empty process to finish. This has annoyed me ever since OS 10.0 was introduced (and probably with OS 9 too, though I don’t remember that far back) — even on my iMacs and Mac Pros when I use a mouse instead of the Trackpad, but it is a more frequent affliction with laptops because the Trackpad is their primary interface device. I currently use OS 10.8.3 on my Mid-2012 13” 2.9 GHz i7 MacBook Pro, OS 10.6.8 on my Mid-2006 20” 2.16 GHz Core2Duo iMac, and 10.8.3 on my Mid-2012 2.4 GHz 12-core (dual 6-core) Xeon Mac Pro at work, and they are all very well maintained with DiskWarrior, Disk Utility, iDefrag, etc. But, this has always been an easily fixable problem. All that needs to change in the operating system is separating these two commands with some other existing command from the File menu, or more elegantly, separating them with a dashed or hyphenated line. Whaddyasay?

Seems to have introduced a nasty bug where my display configuration is automatically changed and a phantom VGA monitor is configured in addition to the two monitors actually hooked up to my system. Googling about, I found reports of a similar bug in previous incarnations of OS X. This is a show-stopper for me since adding that third phantom display degrades performance to an unusable state, especially in relation to video playback. It seems to be affecting my secondary ATI Radeon HD 2600 XT card. I am guessing it is a problem with the updated graphics card drivers in this OS release. I've zapped the PRAM, trashed windwoserver.plist files & cleaned cache files, and tried a clean install... the problem returns repeatedly. Very aggravating.

Why worry about shutdown time? Maybe its being thorough so that on restart potential problems are fixed . Looking on the positive, Messages for me finally logs in correctly at each startup, Safari appears to be snappier and things look to be working a little bit faster. I had hoped for more drivers so that my MacPro E2008 could run an HD6970 Graphics card but one cant expect a 100% every time. After 14 beta's its probable that Apple have fixed many little niggly bugs, aka undocumented features and overall I feel that this update has been worth the wait

When Apple comes out with a new operating system, I usually wait a few revisions before I install it to make sure Apple has worked out most of the kinks. I've been running with Lion for about a year now and have been generally satisfied, learning to live with the perplexing decisions Apple made with the interface. Yesterday, I decided to give Mountain Lion a try. I have been satisfied in the past with the few amount of problems I have encountered migrating to a newer version of OS X. This time was different. I have never encountered a more problematic update experience. Problems with Mail, general slow performance and high resource usage, constant spinning beach balls, all of my addresses disappearing from my Address Book (or Contacts, as it's called in Mountain Lion). The really surprising part of it all is I tried to do many internet searches to find answers to all the issues and even though OS X 10.8.2 has been out there for a good six months, I could find little to no information. I appears that Apple just doesn't care and the user community doesn't seem to much care either. Today, I downgraded my system back to Lion by restoring it from backups. I do not intend to upgrade to Mountain Lion again in the near future, if ever. I seems that Apple has completely dropped the ball on this one as it's a complete disaster. I would strongly advise anyone considering upgrading to Mountain Lion to instead avoid it at any cost. If your system aint broke, for Gods sake don't try to fix it. If this is the kind of shoddy product Apple is putting out now, I'm afraid their best days are behind them and it won't be too many more years before Windows is the only game in town.

I find it very sad that Windows 8 runs faster and smoother on my 2011 mac mini than 10.8.2 Mountain Lion. Internet Explorer 10 is so fast compared to Safari. Apple makes great products, but the software is lacking.

I do understand that there are other vendors who Apple are competing with but still, the extent to which Apple deliberately makes interaction with those other vendors or their associated software very difficult (more so than in previous versions of OS X) is an unfortunate feature of Mountain Lion. It is surely unrealistic to expect to shove everyone onto the Apple ecosystem like MS did with Windows in the 90s. It’s a shame as there is great GUI and power in ML, which could be so much greater if it let its barriers down a little and allowed better integration with other devices and systems. OK, that may be unrealistic these days in an Apple world where it's bossing things and open source is not the thing any more but that's what ML has to achieve if it's to be considered great.

A never ending string of bugs and problems. Literally, every day is a new defect from TimeMachine, to track pad to Mail, to Calendar to Finder. What is worse is that every time a problem comes up, it can be googled and it appears that it is not an unknown problem and frequently something that has been lingering for a considerable amount of time with well defined symptoms not being addressed by Apple.

Is anyone using the command line `softwareupdate` to update ML instead of doing it through the MAS? If so, please share your thoughts on whether it's a good alternative or not. Thanks.

If you create your own disk images (dmg): 10.8.2 introduces a serious bug. The read/write disk images won't open automatically after mounting anymore. You need to Cmd-click them in the sidebar every time after mounting. I just submitted this bug to Apple.

i installed peerguardian about a month ago on my new imac (10.8). a couple of weeks ago i did a software update to 10.8.2 and immediately began experiencing problems connecting with certain websites (apple, google, yahoo, etc.). after 2 weeks of trying to diagnose the problem one of the techs suggested i remove the peerguardian application. right away i was able to visit every website i tried.

Seems this OS needs a bit more time to shut down the computer. There are some things I had in mind for a change but sadly they did not: launching Preferences needs an awful lot more time than it did in not ML-Versions. After a boot the desktop and dock are shown quickly but they don't react to the user yet! Sometimes, in a hurry, it's very annoying: you think you can interact but it's just a show-off :) But it looks like the people @ Apple had success. U don't need a Steve Jobs to be a living matter, you have his legacy ! It works I believe.

Under General fixes: - Adds a new preference to have Safari launch with previously open webpages I couldn't find it under any Preferences tabs, only "Reopen All Windows from Last Session" under the History menu that's been around since Safari 5. Anyone else find it? Regardless, I'd still prefer using David Yoo's excellent Sessions extension: http://dl.dropbox.com/u/8247646/sessions/index.html

Lots of little fixes in 10.8.2 not mentioned in the changelog (why Apple why!?!?!?!). One that particularly annoyed me was the very slow animation changing Spaces with a gesture is now much faster without the long ease-in ease-out s-curve. Overall, update was flawless on about 5 different Macs, and on a retina MBP there have been improvements to UI performance.

Mountain Lion is killing me - ever since I upgraded from Lion my WiFi connection integrity is a disaster. I just upgraded to 10.8.2 in the hopes that it would fix things but it didn't. I'm going to have to downgrade to Lion. So many people are complaining about this on Apple's forums...

Updating my review: Previously, I had kernel panics when waking from sleep after upgrading to OS X 10.8.x. As it turns out, the crashing occurred due to an incompatibility with a third party eSATA card. Once I removed this card, the crashing ceased. However, this problem did not occur under the previous versions of OS X. So, if you are experiencing problems with 10.8 in relation to waking from sleep, try removing third party hardware.

Is there any way to uninstall this and return my beloved MacBook Pro back to its original, fast, smooth, un-choppy, stable self? Honestly, ML has been a disaster. Slow start-up time, unresponsive apps, auto-terminating apps, intermittent internet cuts. I've had enough. ML was a very bad idea.

Utter trash...and I've done dozens of Mac updates over the years--every version and every step since 10.1. THIS installation went very smooth and fast on my new MacBook Pro 13" (SD drive and faster processor)--BUT I didn't notice until I sync'd with my iPhone that it had ZIPPO in my calendar--and thoughtfully wiped my iPhone's calendar as well! Worse, I can't get it to take ANY modifications of the default alert times in Calendar, can't get it to use some of the calendars at all (like Birthdays), and can't get it to sync properly with the iPhone--which otherwise sync'd up with no difficulties. I've been able to recover SOME of my events from my iPad 2 as this ML setup was kind enough to tell me that I hadn't sync'd this iTunes Library with it yet, so would I like to ERASE my iPad and start over? HELL NO! I have several key apps that I use all the time that are no longer on offer on the App Store, so I guess I will have to continue to sync it ONLY with my old MacBook Pro till that one dies or I replace the iPad. I've felt for some time that iTunes sucks since you can't update and combine accounts, and now parts of the OS do too. Calendar in ML is not just useless, it will make your sync'd devices useless as well. The instructions say just restore your calendar from a backup. WHAT BACKUP? Apple doesn't want to trouble you by making things easy to find hierarchically anymore, just use Spotlight--which can't find any backups (though I should have several a week for several months before I upgraded). Wonderful job by some brilliant idiots.

No problem for me with 10.8.1, except that i dont use the toolbar in the finder windows... i love just the plain window... but since 10.7, the windows never get tight around the enveloppes and when you click the red window button, like 3 enveloppes, it close the enveloppe at two folders and one under. Arf! At least they get the launcher to keep preferences in 10,8. :-)

How about "Resolves an issue where Mail repeatedly will not retrieve email from multiple Gmail accounts (through our ISP which now uses Gmail)? Launch of Mail sometimes brings in a few emails for some of the accounts, but ALWAYS leaves that triangular "problem" icon on others (can't connect to server, seems random). Several subsequent manual attempts at retrieving mail from such accounts is futile, but oddly, if I wait for Mail to do the next scheduled check (1 or 5 mins.), more emails arrive and the icons are cleared. A pain, and I never had this problem with Lion.

Two issues with ML 8.1 - one old/continuing, another new. Old/continuing: 10.8.1 doesn't fix washed out colors on external screens connected by mini-DP to HDMI (see extensive discussions at https://discussions.apple.com/thread/4080525) - color gamut is reduced and constrained - image quality very poor. When mini-DP to DVI used on same screen, pictures are razor-sharp HD. New: 10.8.1 breaks "purge" command - no longer works.

Mountain Lion allows a second SATA3 SSD (6.0Gbps) to be used in the optical drive in 2011 MacBook Pro 15-inch models without any problems. There were a host of problems doing this under 10.7, documented by OWC and elsewhere, but 10.8 fixes the issues! At least it does for me and one other report I read on Crucial's website.

Works great on my new MacBook Pro, but on my Mac Pro desktop it fails to wake from sleep or crashes upon sleep, forcing me to hold down the power button for a hard restart if it doesn't invoke an auto-reboot on panic. The problem is reproducible and apparently widespread. It appears there are two major issues, one with bonjour networking, and another with power management. Both of these are involved in causing a kernel panic and crashing users' computers. If you have not yet updated, be sure you have a full back-up in place to easily restore your previous OS, otherwise you may just want to wait until Apple solves these major issues.

I have been using ML since it's day 1 release on a 2.7 GHz Core i5 iMac w/ 8 gig of ram and a 13" 2.3 GHz Core i5 MPB w/ 8 gig ram. Both are noticeably faster now than when with Lion, and I have not had one system or application lockup--correction--Dragon Dictate. Lion on the other hand had app crashes and at least weekly system freezes. I don't like that printers and the archival utility do not automatically quit, but hopefully this will be addressed in an update. I don't like that Safari's cache cannot be easily cleared and just keeps getting bigger and bigger, but PrivacyScan deals with that. Most of the day I am on a computer. Most of my apps are Internet or research oriented, or word processors. I don't do much intensive imaging or gaming. Often the first few weeks of a new operating system can be pretty painful. Other than waiting for Snapz Pro to get up to speed, this has been a painless experience for me. All-in-all, I'm pleased.

The return of “Save As . . .” appears to be a lie. Read this: http://macperformanceguide.com/MountainLion-SaveAs-data-destruction.html Then try it for yourself. Open TextEdit, type the letter “a,” and save the document with the name “a.” Close it. Then re-open it, type a second “a” so that it says “aa,” then “Save As . . .” and name that “aa.” Close it. Now re-open the original “a,” and notice that it now says “aa.” If anyone else is having this problem, I’d like to hear about it. But this is now at least two people who experienced this. All I know is that I was able to re-create the probolem that digilloyd identified in the above article. If this is true, then Apple has deceived us and has done anything but return “Save As.” For this is NOT how that original function worked.

ML has made my computer very choppy. Everything's not as smooth-running as it was under Snow Leopard. The spinning wheel appears much more often than it did before, even though I've run several apps to clean, optimise, and delete junk from the system. I rarely heard the fan before on my MacBook Pro, but that's putting in a lot of overtime since I installed ML. I'm I'm hoping an update will 'calm' my computer and make it run the way it used to.
