How can I get my Mac Mini to move my mouse between two screens?
I'm using Catalina and I've just added a second monitor with a HDMI cable. The screens work but I cannot get my mouse off the main screen to the second one. I've gone into System Preferences | Displays and made sure Mirror Display is Off and I've arranged my screens. But still I cannot use my mouse on second screen.
How do I fix, please?
Also, I use BetterSnapTool and this stops working when I plug in the second monitor. Is this related?
Thank you for your help.
