Question: Mouse stutter with High Sierra - iMac
when I updated fom Sierra to High Sierra a couple days ago, I had the problem that with every mouse I used (Magic Mouse 2, Logitech G403, normal Windows Mouse) there was a sudden stutter in the movement, every couple seconds.
The stutter was less frequent with the magic mouse, but also there and really annoying when you try to work.
So I tried to reset my NVRAM and it was gone. Until today. The problem is there again but now a NVRAM-Reset does not work anymore. Same problem with every mouse I use. The only mouse you "can" work with is the magic mouse, because the stutter happens "only" every 10-20 seconds.
I can not wrap my head around, what the problem could be.
High Sierra 10.13.1
27" Mid 2011
Intel Core i7 3,4 GHz
AMD HD 6970M
Does someone have an idea?
iMac, macOS High Sierra (10.13.1)
