I have an iMac and I stopped using the Apple Magic Mouse because it would randomly disconnect from Bluetooth and stop working. This is scary because I need my mouse to work effectively while I'm executing stock trading orders, so I bought a generic, wired Logitech M100 mouse as a backup. This mouse served me well until last week when I noticed the iMac screen was scrolling up and down wildly without me even touching the mouse. I unplugged the M100 and my iMac screen no longer moved erratically. I wiped the M100 down thoroughly with a special cloth, but it continued to make my iMac screen move. Does anyone have any recommendations for a mouse that would work on a 2017 iMac without any of the above issues?
