The best of its class. I don't even worry about the betas. I just want to know why it's free, doing all that it does so well? I hope users are using his Paypal Donations button at his web site.

BEWARE—THIS UTILITY (MOUNTAIN LION VERSION) RENDERED MY MACBOOK PRO UNBOOTABLE. Executed Cleaning and Maintenance functions, after which the MBP would boot only into a white screen. Saved by a backup clone, or this virus would have put me out of business. USE AT YOUR OWN CONSIDERABLE RISK. DO NOT USE IF YOU DON'T HAVE A WAY TO RESTORE YOUR HARD DRIVE.

How is it a virus?


All OnyX does it run built in scripts and routines, or change hidden parameters that are part of Mac OS X. So it could not have damaged your hard drive.


You likely had an existing problem that the cleaning routine exasperated.

This app has been around for many years now; calling it a virus just because something in your system broke is outrageous. It's not like OnyX doesn't warn you when modifying system files, such as clearing the cache, etc.

Right, it warns you, and it offers to check your disk, which I'd bet wasn't done.
And that's why we have backups.

Maybe calling it "virus" was a bit harsh, but I share these sentiments...
Onyx HOSED my system a couple OS's ago and haven't used it since.
My Mac was unbeatable as well...only the white screen just as stated above. I've heard/read the same elsewhere.
"Use at your own risk" is a wise piece of advice.

I meant "unBOOTable"...spellcheck works double-time to make me look like a dumb**!!!

I tried to leave this on the Titanium Forums, but I am waiting for approval as a new forum member. I am running 10.9.4 with a Samsung 840 EVO SSD and OnyX is "stuck" at between 5-10% along the blue progress bar. I'll have to try to quit it from the Activity Monitor gently at first and forcibly if necessary. Not sure why as all other digs I have run have given me a pass. FYI.

When I try to use the automation tab on my SSD it never gets started the beach ball keeps spinning and I then have to force quit it. Tried re-downloading Onyx but no improvement.

Used it yesterday on 10.9.3.
Developer, is it still ok for 10.9.4?
It's the best of its class.
Can't believe it's free . . . please donate to the continuation of Onyx.

And we meet again! lol

It should be fine to use an older version as long as it works. It's using built in system scripts and services. :)

Ram usage with 2.8.6 is low/way down from prior iterations; glad to see that. Solid program.

Onyx told me I needed to restart and boot into disk utility to repair my disk. It found no problems but Onyx keeps telling me to do it. when I try to run the automation, it hangs and must use force quit.

This has been my favorite and I have used it for years with no problems.

DiskUtility often doesn't see, or can't fix certain problems that other utilities do. You should try something like DiskWarrior.

OnyX is actually a shell for built in scripts/utilities. If it's hanging there might be other problems going on with your system.
