This is simply a MUST HAVE when you own a Mac. The best fix it utility when something isn't working and you're not sure why. I haven't worked on a Macintosh without it since Mac OS X 10.6.

Anyone know if there is a setting in the Ventura version of Onyx to STOP the system from creating 'versions' of a file? I have a 4Gb CAD file I'm working on that insist on Spinning beach ball saving (allegedly in the background) apx every 5 minutes and takes it 20 seconds to do, its super annoying slow down every few minutes. Check the file and the 'last saved' date keeps updating as it does it. If Drop box is running the problem test worse as it uploads each time, plus then downloads on all my other machines, its a royal P.I.T.A. ?

I've been running OnyX for years and just ran the Ventura version on my M1 MBA. It ran for about 1/2 and stalled when rebuilding my Spotlight index. I needed to force quit and prayed nothing was messed up. So far, everything seems fine. So there are issues with this version.

My Mac was very laggy, especially when clicking on links to open in other apps. With some trepidation, I ran the maintenance schedule with default boxes checked. Got the spinning wheel of death after re-start. Left it a long time to do its stuff. Forced a restart and my Mac has been running *miles* better ever since. In short, it has worked brilliantly, but gave a nerve-wracking journey. I wouldn't have risked it if I hadn't done extensive back-ups on CCC & Time Machine. *MAKE SURE YOU USE THE VERSION FOR YOUR OS*

Runs only on OSX 12.x. There are many Mac users who still use version 11 or 10. This is not user friendly.
