The program is excellent at digging into deeply-rooted chunks of macOS, setting and repairing Unix-level functions that would otherwise only be accessed through the Mac’s Terminal program and the command line, and rooting through odd settings to restore functionality after you’ve slogged through strange errors and weird behaviors from your Mac. With Onyx at hand, permissions can be repaired, databases rebuilt, file structures reorganized, hard disk structures checked, and indexes restored. It’s been a long time since the heady days of 2003, and along the way, French developer Joël Barrièrehas has continuously released steady updates of the popular free customization and maintenance tool. Since the days of Mac OS X 10.2 Jaguar, Onyx has been in the arsenal of Mac techies to help fix Macs and assorted operating system weirdness. It offers a great set of tools and an incredible level of customization.
There’s a reason Onyx has been among the tools of choice for Mac techies for such a long time.
