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.

I cannot seem to install OnyX due to an error message I keep getting that reads: "The disk needs to be repaired". ' To repair your startup disk, restart your computer while holding down Command-R, then select Disk Utility.' " I've run disk repair from within Utility, but with no success.

5 star app, been using it for many years on laptops and minis - multiple generations of hardware and OSs. Excellent software, reliable and worth running about once/week to clear caches and reset various parameters not normally done by simple restart. Highly recommended! 5 stars - no hesitation!

I have been using for a long time along with another paid maintenance app. When the other app started charging full price for an upgrade I dropped them and only ue this. It is as good as it gets for its purpose.
