As per my note above, can I confirm if the folks in this thread are using the latest version CCleaner for Mac 1.18.30 (https://www.ccleaner.com/knowledge/ccleaner-mac-v11830) which was released October 6th, or an earlier version?

 

Also we have had some feedback that some customers experiencing issues on BigSur 11.0.1 found their issues resolved after updating to BigSur 11.1 - indicating that 11.0.1 may have had some bugs that were fixed from Apple's update.

Anyone still experiencing issues with BigSur 11.1 / CCMac 1.18.30 ?

I'm sorry to confirm, but the issue with CCleaner Pro v. 1.18.30 "Run CCleaner" option (dropdown menu) still does not work on Big Sur Version 11.1. This has been a persistent issue across all versions of macOS Big Sur. I have been running Avast Premium Security for Mac across macOS Mojave, macOS Catalina and macOS Big Sur. It is only under Big Sur that the CCleaner dropdown menu option is non-functional.

I am running a clean install of macOS Big Sur, and security settings remain the same in Big Sur as they have in Mojave and Catalina (Firewall On, Stealth Mode enabled), and CCleaner v 1.18.30 has full disk access. I have a 2017 15" MacBook Pro, 3.1 GHz Quad-Core Intel Core i7, 16 GB RAM.

Any help would be appreciated.
