I’ve been getting bothered all day by my Mac going really slow. Ridiculously slow.
Anyway, I played around with a few things and bla bla bla. Eventually I noticed that Teamviewer was running in the background and it wouldn’t quit. So, I uninstalled Teamviewer and now my Mac is back up to full speed.
So, if you have a slow Mac then I’d suggest ditching Teamviewer.
You’re very welcome.
