We are so lucky to have Joel, the inventor of all versions of Onyx . He gives us a free system utility that works better than any other out there, including a lot of the paid ones. He asks for donations — https://www.titanium-software.fr/en/donate.html — and I do believe it is time for many of us to see that he's paid for the work he's done, for us, for Apple, and for the OS we all love. Thank you again, Joel. I know you're not a millionaire yet, but bless you for sharing your gifts!

Just started using this yesterday and so far I'm blown away! It drastically reduced the amount of space my "other" component was taking up in Mac storage. Performance seems better too. Great cleaner!

It is amazing what a small developer can do and what huge multi-national companies cannot. This app is a remarkable tribute to Joel Berre the developer!

Essential. Practical, easy to access, space-saving. An application to always have on your hard drive.

Great app, helps when Mac's acting a little strangely. Non-destructive, safe routines. Easy to use. I recommend it to all whom I help with Mac problems. One thing, though: Titanium's website lists a newer version for Mojave, 3.6.7; it works fine. To all: donate! It's worth it, and they need it.

Problem with the new app. After going to the "Full Disk Access..." and following the instructions I clicked OK. The "Full Disk..." window closed. Onyx quit. I reopened Onyx again and got the "Full Disk..." window. Clicked ok. For some reason, Onyx never opens like it used to. Also, no mention, if you need to reopen the System Preferences Security & Privacy to close the lock. I am using macOS Mojave 10.4.6 supplemental update.

This is unfortunately a problem with the current version of macOS, it's not Onyx's fault. I've had the same issue with other apps. Restart your computer and it will work as it should. Also consider adding more stars to your review so as not to penalize Onyx for a macOS problem.
