After upgrading to Catalina [Mac Mini 2014 vintage] the cursor jumps. Rebooting fixed for about 3-4 days but it has now returned.
Restart in Safe Mode. Test. Safe Mode is slow - that’s ok. Do you see the same problem? Restart normally again. If the problem reappears please run Etrecheck and post its report here.
Etrecheck is a diagnostic tool created by a respected member of this community to help users help by providing a report about a system. Often problems can be caused by software modifications that the user may not even know are installed. In order to help one needs information, and often the solution presents itself just by reading the report.
Thanks for your help. Perhaps I'll try that app.
Thanks for your reply. Since rebooting [in the normal way] fixed the problem before, won't doing it again not be a definitive test? I don't know what you mean by Etrechek. Thanks again.
