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.
Mike
