I currently dont have a licence...just wanted to test CCleaner, but it just wont start on my Mac Mini with the newest MAC Os (no other Updates available).
Any suggestions? I want it to work, before i buy it :)
I assume that you downloaded CCleaner for Mac 2.08 from the official website (https://www.ccleaner.com/ccleaner-mac) and are using macOS 10.12 or higher? Note that if you picked up an old CCleaner for Mac 1.x from somewhere that's been end-of-lifed and is unlikely to work on MacOS 11 or higher.
