Apps freeze when starting up on my iMac
Hi, I am getting a problem where apps often freeze when I try to start them up. I have reinstalled the OS (Catalina 10.15.7) twice, I have flushed the app cache in the library also twice, and I have uninstalled MacBooster - since I was told that could be the problem. I uninstalled and resinstalled MS Office, since those were the apps I was using most often. On each fix, the computer is quite responsive for a few days, and then it's back to beachballs. So I spend a lot of my working time fixing - or trying to fix - problems that are preventing me from actually working.
Today I tried to open an Excel file. It took more than two minutes from the app starting to bounce in the dock to me eventually getting a message saying 'application not responding.' I then tried to open the file in Numbers. No result. Similar when I tried to open Outlook.
This happens in other apps too.
Apart from putting my fist through the screen, are there any other options for fixing this problem?
Note, tech specs are iMac late 2013, 2.7GHz Quad Core Intel Core i5, 8Gb RAM.
