I have a mid 2020 27" iMac. After upgrading to 14.1.2, everything is running just a little slower, particularly when typing (even this post), working in spreadsheets, etc. There is a noticeable delay. I can't see anything untoward in Activity Monitor that's hogging a bunch of CPU or memory. Anyone else seeing this? I only have 8GB of RAM and ordered an upgrade so I'll see if that changes anything, and I supposse 14.2 is coming out next week which might resolve any problems I'm having.
