amusesmile Updating to Catalina caused in instantly so I reverted. When that laptop died because the keyboard could no longer be repaired I bought the same hardware model which had been updated to a newer OS and caused strain issues. I used a factory reset and time machine backup to boot into Mojave and it was fine again. On this machine for my eyes Catalina OS and newer were the culprit.
This mirrors my own experiences. I have a Mojave Macbook Pro 2103 in front of me.
