iOSScreenCaptureAssistant This seems to be a problem in Sonoma causing a lot of hangs.
What is this? Is this part of the OS or a 3rd party app?
It's part of the macOS, but I have no idea what it's doing in it. It appears frequently as the cause in hang reports in Sonoma.
That's just my Time Machine drive. I don't think I'm supposed to clear off its space manually? Should I just disconnect it whenever I'm using FCP?
That's fine. I didn't notice any sign it was a TM drive. It's not a problem then as the OS removes items as needed.
Why does Chrome need to be removed? What if I need to use it on a regular basis? What are the keystone daemons?
The keystone daemons that Chrome installs that run continuously to do update checks and flood other resources like the VideoToolbox. Use Brave, or Opera, or Firefox.
Why not (genuinely asking)? It's what I use to block ads and suspicious stuff when I'm on the internet. It has come in handy many times for preventing weird pop-ups.
Anything that runs continuously to check content can cause problems. If it's not doing virus checking and only running in a browser it shouldn't be a problem.
What exactly is it in the report that led you to this conclusion that it has damaged the system for pro apps? I find CMM to be really helpful for shredding files and looking at how my SSD's space is being used.
CMM has been a major problem for years. It "cleans" up the system by removing what it sees as unnecessary files and often damages system resources used by pro apps. Many users have had to do full wipes to rebuild their systems.
Every OS is different and users should never assume that everything that previously worked will continue to work as it did. I think most pro app users still always test new systems first and do a full wipe and clean install to rebuild to a new operating system rather than migrating applications and their system content. Migrating users and files is fine, but everything else should be rebuilt.
