Since most of the same questions are older, I'm asking it again. I have an iMac, 21.5", Late 2012, processor 2.7 ghz, Memory 8 mb, Catalina 10.15.4. I've notice the last year and it's getting worse, it is so slow in opening a program, or doing most anything. It's especially slow for the first 10 min after I 'wake it up'.
I see some one suggested running the disk repair feature from Applications. Is this safes without a complete backup? I love the iMac but it's getting harder to stay in love with it at this rate.
