iDefrag required to restart my mac to be able to work with the hdd (which is only one in my mac, where is also OS installed) and now it got stuck for more than 10+ hours in the loading screen (apple logo - at startup)... should I abort it by turning off the mac? Anyone knows it's frozen or what should i do? Thanks a lot guys
so i would rate your app cause i am a beta tester ,but the problem is i never got to try it it downloaded fine but when it was opened i recived a msg that it was damaged and to toss it out so thats what i did .something you should look into .let me know when you have fixedit and i will give it another shot
I did benefit from this nifty utility for many years and now it’s gone for good. At least the developer has been generous enough to offer it for free to those who still use the older Systems. Just go to their site to pick up your free license. Fariborz AMIRSHAHI - Verona (Italy)
From the Coriolis website:
"Support for this product has ended. iDefrag works fine on macOS 10.12 and earlier, but has some problems on macOS 10.13 (High Sierra). There will be no further updates or bug fixes; the product will remain available for download and purchase for the benefit of users running earlier versions of the macOS."
Hi MU community! I hope someone might be able to advise me here.
I recently upgraded my OS from 10.7 to 10.9.5, and I already had iDefrag 1.7.3 (229), which I'm using now.
As we speak, I'm about 14+ hours into a iDefrag Optimize on a 4TB external drive that only has 650GB used, and the Location Indicator is only about halfway through the populated area of the Whole Disk Display. I'm wondering: Does this mean I have another 14+ hours left to wait for this, and if so, is this normal/OK for iDefrag to take some 14-28 hours to optimize 650GB on a 4TB drive?!
Here's my setup:
iDefrag Version: 1.7.3 (229) Algorithm: Optimize Class Set: Default Enable per-class sorting: SELECTED/CHECKED Skip files that cannot be defragmented due to lack of free space: SELECTED/CHECKED
External drive being defragged/optimized Brand: Seagate Model: Expansion Portable HDD (STEA4000400) Size: 4TB Connection: Seagate's USB 3 <--> Elgato USB 3
Dock/Hub Brand: Elgato Model: ThunderBolt 2 Dock
ALSO - Regarding upgrading from iDefrag 1.7.3 to 2.2.8 (per Corialis website suggestion for OS10.9.5): a. What's the process? b. What's the cost? c. How would it benefit me (if at all)?
I look forward to some help, as my work is halted until I finish defragging some drives, and I'm wondering if I need to budget 28 hours of computer downtime per 650GB of hard drive defragging :-|
I haven't tried the software but just wanted to point out that 'defragging' a modern SSD hard drive will have no benefits and will actually decrease the life of your SSD. See http://helpdeskgeek.com/featured-posts/should-you-defrag-an-ssd/ for more info.
While it is used the version recommended according to S.O works perfectly. If you install the 5.1.4 (or superior) in Yosemite or El Capitan, can damage the disc, so that there is to reformat and to reinstate everything.The system of updates of the program, must have had this in account.The last compatible version with Yosemite and Capitan is 5.1.3 and now it does not try to update to a later one, as it must be.It is a good program, and it helps enough to maintain discs in sequence. But from time to time, the updates are not without risk. Due to him, I have had problems several times, the last ones with the passage to Yosemite,and it makes a pair of months with these incorrect updates of iDefrag.In addition, it is possible that some problems that I did not know to identify also came to use one more an up-to-date version of the indicated thing.
Long-time user (since version 1) - using it primarily for a series of external hard drives. I have 8 x 3TB drives for paired backups of my image collection. Lots of file transfers, editing, swapping etc. I use iDefrag to keep the drives in good working order. Every 2 months or so, full defrag helps to maintain drives and all my precious backups in good working order.
I was caught up in the registration snafu but all of my experiences with dev over the years has been v positive - I am in Australia and I get a response the same day or within 24h.
Recommended software and supoortive dev - worth looking at iDefrag for protecting your drives.
Is it still necessary to defragment a drive any more? I've been told that it is not needed if you're running the newer OS such as Sierra. And of course, you cannot (or should not) defragment a SSD.
Warning with version 5.1.5. I use an iMac with Sierra 10.12.2. After having updated iDefrag to 5.1.5, the Mac was very slow at startup and also impossible to shutdown. Impossible to run a Disk Utility or OnyX or Time Machine. I have contacted the developer but no news for now.
I am not pleased with this developers idea of customer loyalty. I have used iDefrag for many years and in truth I find no fault in the way it performs - mostly. I stopped using iDefrag about 5 years ago. I was having a good deal of trouble with it’s licensing and DRM set up. I was using a hackintosh setup and while their DRM was part of the problem, my set up could have contributed to it as well. I finally gave up.
I now use an iMac and have returned to the mainstream Mac fold. I am ready to revisit iDefrag as they have continued to improve their software and a few versions have gone by since I was a customer. I am willing to try again if they would offer an upgrade to a former user (and fan). Sadly, they do not. A line was drawn in the sand and some users were left on the other side of the line. Version 1 users must repurchase a license as new. All other versions will qualify for an upgrade price.
I wrote the developer and asked to renew, but I was flatly refused. I appreciate that a developer has to earn a living but I also appreciate good customer service. A returning customer after 5 years who left at least in part due to the software having technical difficulties should, in my opinion not have to start over and repurchase a license when upgrade pricing is available. Isn't that at least a part of what upgrades are for, to reward loyalty? Sadly this is not the case with this developer. Your mileage may vary.
I wanted to update from 5.1.1 to 5.1.2 a couple of days ago. That was A BIG mistake! For some reason iDefrag wanted me to drag my license into the registration window again. So I did. Nothing happened. I reverted back to 5.1.1 but even then I got the same problems!!! I contacted the developer(s) via E-Mail THREE (3) times already and they have not bothered to get back. And this is supposed to be a good service?!?! Screw that for a joke! If I don't receive an answer from them by the end of this week I will regret having ever supported the developer(s), trash iDefrag completely and look for an alternative. I'm an honest paying customer and I'm pretty pi**ed off. Think twice before buying a license for iDefrag because the support sucks.
I have been unable to get iDefrag 5.1.2 to download, either from here at MacUpdate or at the Coriolis web site. Seeing these recent reviews I now count myself lucky. Coriolis' notion of "broken license files" sounds more like a broken application problem to me. This is unfortunate as iDefrag has been working well for me for many years now. Until Coriolis has an answer for this problem, or better yet a solution, I will stay with version 5.1.1.
Now it may be that most users are not having a problem with iDefrag 5.1.2, but the fact that some people are, and that Coriolis has not seen fit to respond to the issues they raise, is good reason for caution in my opinion. The fact that I cannot even download 5.1.2 only adds to my apprehension. "Caveat emptor."
DO NOT DOWNLOAD THIS PIECE OF CRAP! I have used iDefrag for years, but as of this version, YOU CANNOT LICENSE THIS VERSION OF THE APP, EVER!!! It will ask you for a license key EVERY TIME YOU LAUNCH IT, and until you find the file, IT WILL LOCK UP YOU MAC!!! You can't even shut it down. I had two licenses, which it took every time (I tried about 10 times). Every time I launched iDefrag, it asked me to find the license file AGAIN! I finally paid for an upgrade, and put the license file they sent me into the iDerag folder in my Library, but even after I browse and find the file, IT STILL ASKS FOR IT EVERY SINGLE TIME I LAUNCH THIS PIECE OF CRAP!!!!!!
This dot release (5.1.2) doesn't accept the original License one drag's and drops. Not sure why it would even ask for this since it's a dot release. The previous version, 5.1.0 crashes if one attempts to update from within the app.
I'm not sure this is the proper place to ask this. However, here goes. I have an early 2011 MacBook Pro 17" with 252 GB SSD and 8 GB Ram with OS 10.10.5. I am taking some time to delete duplicate files I have filed in several places and open up the space available. In doing this I noted that the available space DECREASED as I was deleting files. I thought this might be due to holding something in memory. I shut down completely & restarted. No difference. I went from about 110.34 GB available to 109.96 GB.
Today I began again starting at 109.96 GB and watched. No decrease OR increase in the available after deleting a number of files. Then when I tried to rename a file, and was told I was unable to do so because I was out of memory. This after doing that a few times already without problem.
It has been years (not since the old 8600 machine) since I had to defrag but I was thinking I might need to do that. Now with the SSD and the OS X system I don't defrag and it is no longer presented as part of the OS.
While searching for an answer, I ended up here. But so far I have no answer as to what is going on except that I'm beginning to wonder if my eyes are playing tricks on me or I'm finally just going nuts. Does anyone here have any suggestions or locations to go to find answers about this? Hopefully on one will confirm my last two thoughts about possibilities above.
Hi! V. 5.1.1 has been out since December(?) Why is it showing up on Macupdate now?
I'm on 10.10.5 and neither 5.0.1 or 5.1.1, boot into iDefrag. The computer restarts and goes right into Finder. I've emailed Coriolis 2 months ago, but never heard back which is unusual. Anyone with similar experience? Thank you
Attention because Coriolis is not serious! I paid 1x Upgrade and have never received my new license by email. They say that it is the fault of your provider and do not return a copy. Then despite numerous reminders, they do not respond and do not repay you !!! Crooks ... I'm furious!
This software is mostly irrelevant in these days of modern computers. It is based on psychological weaknesses or neurosis in it's users. If you really want to improve you HD performance try DiskWarrior and Onyx.
I use this app frequently and can recommend most highly. I have 18TB of large HDDs (6 x 3TBs) for my digital image archive and 4 or 5 'baby' HDDs (WD 1 and 2 TB portables for backing up images while out on in the 'field') and use iDefrag regularly to maintain my drives, optimising the disk space available and ensuring high reliability of drives. Plenty of info/advice on why not to use defraggers on SDDs, but I believe most of us are still using/relying upon HDDs. Essential app for me and with plenty of options as to defrag operations, useful for all.
"The update did not decompress properly; this may mean that the download was corrupted. Please retry the update, and if it fails again, notify the developer."
I've tried updating from within the application twice. This doesn't instill confidence in a program that touches every file on my hard drive.
Other than this, a good application that I've used for years.
I stand corrected. I seems to work even with this error message.
THIS UPDATE DID NOT DECOMPRESS PROPERLY: POSSIBLY CORRUPTED. PLEASE RETRY THE UPDATE, AND IF IT FAILS AGAIN, NOTIFY THE DEVELOPER.

Can no longer use my purchased 2.2.6 version, has worked fine for ages, after a re-install of OS X just get asked to login for a key or something and the account page doesn't exist anymore. I am forced to upgrade to this version 5 ? Bully tactics. I'm upgrading to SSD anyway so no worries really, but liked to defrag my big old hard drives. I'll move on I think...
I have a paid/registered copy of this application.
However i am not exactly sure that it is really required in the scheme of MacOS 10 or even 9 namely because as soon as you defrag and start adding or deleting files the hard drive becomes fragmented.
As best as i understand in my research of Mac OS 9 and 10 the optimization of the applications/files is done for you when you run Apple's Disk Utilities or even when you install Apple's applications. For example installing a Combo update.
Therefore running a "defrag" hard drive is a waste of my time.
My wife has used Macintosh computers for more then 25 years and she has never worried or done any sort of fragmentation. She only runs Apple's Disk Utilities to repair permissions after every installation of a new programme or update.
Just to note that iDefrag actually sells for £22.95. Currency conversion rates fluctuate. £22.95 currently converts to $34.50. Add any credit card fees.
I wish they offered PayPal payment.
After upgrading to version 5.0, iDefrag crashed during a full optimization and trashed my drive. Other drive utilities could not repair it. Luckily, I had a backup or this could have been a complete disaster. Coriolis Systems explained the crash as being due to bad license files and issued an upgraded license file.
While I've used iDefrag without any problems for years, crashing and losing a drive because a png image of a license is corrupted is inexcusable. iDefrag should have immediately quit without starting the optimization. I'm extremely hesitant to even try running iDefrag again. This is my last update.
It would seem that replacing the license has done the trick, I have successfully defragged two 20Gb drives and one 182Gb drive today with absolutely no problems whatsoever. I now feel confident in using the App on my main drive again, (of course, I do have a backup!). iDefrag has been my goto program for defragging since version 1 and hopefully will be for a long time to come.
Can happily report that having defragged two small drives with my re-licensed version 5, it now appears to be working correctly. Am now in the process of defragging much larger drive, will report upon conclusion.
Upgraded to day to 5.0. Tried first a full defrag and then optimization on a secondary drive I use for achieved data. Application crashed both times. When I tried to send a report to Coriolis both times, that failed too. Not a good sign!
iDefrag 5?????? Either I missed something along the road or I’m not good at math. Last up-to-date version running just fine under Yosemite 10.10.3 was 1.7.3., of which I’ve registered version 1.0 some 11 years ago and which has served me well throughout all MacOS X iterations.
I don’t mind paying for an upgrade, but what justifies the jump to 5? Or the upgrade price of USD 20 for that matter?
Here’s what’s “changed” since 1.7.3:
+ Fully OS X 10.10 Yosemite compatible version.
Ahem, the last version was running fine without problems. Just as a sidenote.
+ New Yosemite-style UI.
Couldn’t care less.
+ New “Selected Files” algorithm.
The original algorithms are just fine. I’ve never done anything but a “full defrag” anyway. And everybody I know hasn’t changed to another algorithm either all those years.
+ New, rewritten documentation.
Yawn, who cares?
+ Better handling of bad blocks.
Yeah, nice to have. But again, is it such a major step forward? iDefrag was pretty good at handling bad blocks already.
+ Improved support for Retina displays.
Who is looking at the app when it does it’s tedious job? I couldn’t care less for Retina support.
+ Simpler, easier-to-understand statistics
What statistics? I’ve never read them anyway.
Overall, this is a weak upgrade at a hefty price tag. I’ll stay away from it and suggest to stick with 1.7.3 for the time being.
I've had no trouble with iDefrag 2.2.8. I used it recently to defrag and reorder the files on the 1GB Fusion Drive in my 2013 27" iMac. It restored scattered system and application files to the 120GB SSD portion of the drive. As a result, my system runs faster and apps start more quickly - as they should.
I had previously been using TechTool Pro to defrag my drives, until I noticed that it had no file priority options. iDefrag offers a number of these - as the old Norton Utilities did. On a stand-alone SSD or HDD this might not make much of a difference, but the performance difference between the two elements of a Fusion Drive is significant.
As for iDefrag version 5, if you are currently using Yosemite, my sympathies. In case you hadn't noticed, it's still effectively in beta; the OS X 10.10.3 update has just been released to the general public for beta testing, as the first iterations of Yosemite were. Now, six months after it supposedly came out of beta, Yosemite is still not ready for prime time. As a result I won't be upgrading my mains system until I read reports from early adopters that version 10.10.3 is stable and all, or at least most, of the persistent bugs have been fixed.
Because I upgraded to iDefrag 2.2.8 not long ago, and am still running in Mavericks, I will have no need for version 5 any time soon. When the time does come for me to move to Yosemite, I will consider iDefrag 5. In the meantime, iDefrag 5 has arrived late only for those brave enough to have migrated to an unfinished version of OS X. For the rest of us the delay, if you can call it that, has been no inconvenience at all.
We’ve had a few queries from people who’ve been sent free upgrades; if you purchased iDefrag 2 after 1st September 2014, you will have had an e-mail from us with an iDefrag 5 license in it. This is normal — we always hand out free upgrade to people who purchase close to the date of a new release, though in this case we’ve gone a bit further than usual because of Yosemite.
Anyway, if you’re lucky enough to have one of these, it’s free, you don’t need to pay anything for it, just go and download the new version.
Also, some of the people who received this e-mail and tried to activate straight away might have had problems. If you did, please try again; it's probably fixed already.
Just what is the problem with the 'forthcoming' Yosemite-compatable iDefrag 5?
Yosemite has now been out for a good 5 months, 'Drive Genius' is able to defrag yosemite drives, as things stand, we only have another 7 months or so before the next OS release, are we being asked to pay for an upgrade from version 2 to 5 for software that may only run on our Macs for little more than half a year?
Now we are told that, quote: Coriolis 'are trying to get their new website up and running, so that they can release the new version', since when was a new version of software reliant upon an updated website? I'm afraid that Coriolis appear to have dropped the ball here!
If you’re having difficulty updating to version 2.2.8, please see our blog post, here:
http://www.coriolis-systems.com/blog/2014/09/gatekeeper-and-os-x-1095/
which explains what’s going on.
Outstanding application in this iteration it is superb. I just did the full defray and I would expect great speed as I did many times before. It works on 10.6.8 as well. I agree with RavenNevormore that this is a great application and worthy of 5 Stars or more.
I am not able to upgrade from version 2.2.4 - the installer destroys original app and politely informs "Unfortunately, your copy of iDefrag has become corrupted and it is not possible to continue.(...)".
Mac Pro/12 cores, OSX 10.9.4
I used to use TechTool Pro to defrag the volumes I use in my Mac tech support business. I have to be able to run maintenance routines from various versions of OS X and have to keep them all in good condition. When I previewed a partition recently with iDefrag I discovered that TTP left files in rather random order. Unlike TTP, which pays no attention to file priorities, iDefrag optimizes a volume by putting like files with like, and puts system and catalog files nearer the center of the drive so they can be accessed more quickly. Some may question whether this makes any real difference and I cannot prove that it does, but it appeals to my personal sense of order. So I now use iDefrag to tidy up all my drives and partitions.
Coriolis has been around for a long time and they keep iDefrag up-to-date. These days when new Mac utilities are proliferating madly, I'm inclined to stick with more experienced developers with a\\ well established reputations.
I cannot properly load the coriolis-systems.com webpage using Safari 7.0.6 (with Mavericks 10.9.4). Paused the blocking that Ghostery performs. Is it ClickToFlash perhaps? Anyway, it works with Chromium and Firefox. <shrug>
-HI-
FYI: I asked the developer about using this with SSDs. He responded to say that version 3 is nearing release candidate status and will defragment SSD volumes, including Fusion drives.
Since an SSD wears out after a certain number of write cycles, defragmentation is normally not recommended. iDefrag 3 will defrag SSDs by directly accessing the controller to manipulate the drive's garbage collection and wear leveling routines. The developer I spoke with couldn't say which drive controllers would be supported, but it's a fair guess that it will at least work with Toshiba and Samsung controllers since Apple uses them as OEM SSDs. What the developer did say is that their SSD defragging will yield bigger gains than HDD defragging. Even when run on a virgin OS X installation, gains of up to 1.3x were realized. That's right, Coriolis's SSD defrag heuristics are superior to Apple's own Mavericks installer!
This will be HUGE for the Mac community. Until now we've been punk'd by OS X's poor TRIM support, but soon we'll have the first and only SSD defragmentation utility on the market! I can't wait to see how fast my Mac Pro is after iDefrag 3 works it's magic!
