I have used CCleaner for many years on my 27" early 2013 Mac running OS 10.15.7. When I tried to download the update to the latest CCleaner version 2.* it will only install ver. 1.13, and then it will not start up. I have tried uninstalling, reinstalling, cleaned all cache, cookies, and other items, but the program just will not start up. No message is given as to why it won't start up. I know that I need a newer Mac but I do not like the newest version with a separate Mac Studio and Studio Display. Is there a way to get an earlier version of CCleaner that might work? Thanks for any help.
Make sure, of course, not to accept any update and to turn off any update functionality in the software so it doesn't update to version 2.X when using this version.
