When you first start up Onyx, the first thing you see along with the Software License Agreement is the message to Back Up Your Data. To get back your files just restore from the backup you made.

If you are still having problems, click on the the link to Visit Developer's Site at the top of this page, and then ask your question in the forums there.

Hi and thank you for your reply, it worked after I restarted. Can someone tell me how I delete my account here (and this comment possibly)

An important question: Can the permissions for an installation of OS 10.7.5 on a portable USB or FireWire drive be accurately fixed using Apple’s Disk Utility from an OS 10.6.8 startup disk? In other words, are permissions OS-specific, or can one OS’s Disk Utility accurately fix the perms of a different OS?

NO, permissions can only be repaired by the same OS.

That’s not what I asked. I’m wondering if the permissions of an OS 10.7.5 disk can be repaired using Disk Utility from a 10.6.8 startup disk. In other words, are permissions OS-specific, or can they be repaired by any OS?

That's what I answered. Although you would be able to repair permissions on your 10.7 install from your 10.6 disk, you definitely shouldn't as they have different install packages - attempting to do this could actually make any permissions problems worse.

However, you should be able to boot into recovery mode on your 10.7 install (hold down option key at start-up) and repair permissions from there. Otherwise, you could boot into single-user mode and repair permissions from the command-line - ONLY use this option if you are confident using the command line, although the actual commands aren't that difficult if you are.

Hmm, I misread your first response. Thanks for that.

Your second response helped clarify for me that it’s possible but stupid, and therefore not recommended! Thanks for that, too.

Listen...Listen...what don't you hear? That darn start-up chime. Thanks developers---silenced both my 27 inch iMacs (2010 and late 2012). Now my wife can sleep undisturbed:)

Great utility. It solved a persistent "spinning beach ball" lag that was steadily growing worse on my Macbook Pro. The Onyx maintenance script restored my laptop to usability once again.

First of all sorry for my bad English ..
Still many compliments to the developer Onyx. Now thanks to this program I was able to solve a problem discussed on many forums (even the official Apple), but not yet solved ... https://discussions.apple.com/thread/5490918?tstart=0
Thanks to Onyx the problem has been eliminated, it would seem a problem with Spotlight is that due to the indexation of corruzzione email ....
Thank you again ..
PS, I tried to bring this solution within the Apple community, but my post was promptly done away with!

I can't say enough how grateful I am to have OnyX. It has always been a fully competent system utilities app. It also has a beautiful look and feel, a real thoroughbred! I recommend it to any Mac user who wants to keep h(er)is Mac running smoothly and pleasurably. A real gem!

Eaasiest, most reliable utility app i've ever met :) It even solves that persnickety problem often encountered with Trash. Onyx will take care of even taking out the garbage :)

Gitte had trouble on 02 Feb 2014
I'm new to Mac and someone advised me to run Onyx on regular maintenance basis.
On first run it locked up and I could only move the mouse pointer. Clicking in anything did nothing at all.
The only way to get past this lock up was to shutdown by pressing the on/off button of my iMac for several seconds.

Seeing this program gets a lot of positive reactions, it may well be my new iMac caussing this? Should I return it? Should I run Onyx again?

Please advice.

I just saw that the ability to change the Login image has been restored in version 2.8.2. When I change the image, either one of my own or one of Apple's included backgrounds, my Sleep, Shutdown and Restart buttons disappear. They seem to still be there because if I click on the area where a button should be (for instance Sleep), then the command is executed. Note that I do not have the button checked to hide these items on the Login screen.

Any ideas on this? And yes, I did read the manual.

BTW this has been my favorite utility since it came out!

Thanks

It seems that OnyX on my machine gets through the entirety of Automation until it gets to the Deleting the Trash contents part. It's been stuck on that part for more than 2 hours, but I'm hesitant to force close the application. I deleted the trash contents myself, so was pretty confident that there isn't much to do there...

I'm running OS X 10.9, if that helps. Anyone know what might be going on?

User-Name had trouble on 15 Oct 2013
As a habit (for years now) I run "Automation" once a week. 2 days ago my 2012 iMac (10.8.5) could not boot up after running Automation. I had to re-install Mountain Lion, which fortunately restored the iMac to prior-condition without losing anything.

Thinking it was an isolated incident and perhaps my iMac was at fault, I ran "Automation" on my 2010 MacBook Pro (10.8.5). Regretfully exactly the same thing happened.

I searched and no one seem to encounter the same issue... but having it happened on both my Mac seems unlikely I'm the only one experiencing it.

Davelon had trouble on 15 Sep 2013
Using 2.73 Onyx messes up my permissions such that I have to do a restore from backup to use the disk.

This happened before with earlier versions but I wasn't 100% sure it was Onyx but today I ran it only for permissions and boom, useless disk with lots of "you cannot use that " etc due to not having the right permissions and we are talking about my home directory. Running other permission repairs does not help.
Is this just my machine or have others had this issue?

I can't seem to update the program from within the program itself. It always says that there is an error, the site may be down and try another time. This has happened with several different attempts.

I wind up downloading from MU and replacing the program manually. Anybody else have this problem?

This is for Onyx 2.4.7 on Lion 10.7.4
re: scripts hanging. Took over an hour to run Automation scripts. Partial solution is to keep clicking (periodically) in progress bar while waiting for script executions to finish. It seems to help "unstick" the scripts. More permanent solution is to delete Onyx and install YASU, at least until developer fixes this glitch.
