My Imac is very slow and unresponsive

My iMac is having a lot of small issues, after I installed Xcode. I don't really know if the problem is Xcode or another app. My Mac running macOS big sur. But before I installed Xcode 12 everything was fine. I really need help.

Download and run Etrecheck. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support  to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.


Copy the report



and use the Additional Text button to include the report in your reply.



IMPORTANT: ⬇︎ ⬇︎ ⬇︎

Before running Etrecheck assign Full Disk Access to Etrecheck in the Etrecheck's Privacy preference pane so that it can get additional information from the Console and log files for the report:


Also click and read the About info to further permit full disk access.



Then we can examine the report and see if we can determine what might be causing the problem.
