So it turns out that Google Chrome was making everything on my computer slow even when it wasn’t running, because it installs something called Keystone which is basically malware. I made a website because this shouldn’t happen.
I'm currently using Safari every single day. It is lightning fast and I love the tab overview feature. I miss Firefox's Containers feature - but I'm trying my best to stick to apps that are truly Mac apps.
I can't see a single reason to have Chrome installed on a Mac these days since so many browsers use similar rendering engines. Even on Windows I would think Firefox or Edge would be better. I've seen some say they need Chrome for some services but I'd wager only Google services require that.
