Google Chrome might be bad, but it’s not slowing down your Mac

This weekend, developer Loren Brichter released a website claiming that Google Chrome for Mac — or more specifically its auto-update mechanism — was causing the WindowServer process on macOS to constantly have high CPU usage, damaging the performance of macOS, even on high-end machines.

The website includes information on how to completely get rid of Chrome and its updater from your Mac to get your performance back, and went as far as calling it “malware” (that word has since been removed). Many users have reported that this does work and that after removing Google Chrome from their machines, everything got a lot faster.
