iMac / magic mouse problems
My iMac 2020 (last Intel iMac) and magic mouse developed a very frustrating problem in recent days. The mouse cursor does not track smoothly. It sometimes jumps around. My iMac upgraded to Sequoia 15.3 a couple of nights ago. The problems came up after the upgrade. I've tried the usual solution ... close all the apps and restart. Did not resolve the problem. Any ideas??
As an aside, why has Apple not used its vaunted AI to upgrade the support experience? There may be a solution to my problem out there ... I'm just not clever enough with search terms and filters to find it.
iMac 27″, macOS 15.3
