Yeah, I realize this sounds like a freakin' infomercial, but it worked so well I spent a whole $5 on a domain name and set up this website even if it makes me sound like a raving nut.

OK that's weird, how do you delete Chrome and Keystone?

(Update 12/15/2020, if you're technically inclined and can contribute samples please see this thread.)

  1. Go to your /Applications folder and drag Chrome to the Trash.
  2. In the Finder click the Go menu (at the top of the screen), then click "Go to Folder...".
  3. Type in /Library and hit enter.
  4. Go to "Go to Folder..." again.
  5. Type in ~/Library and hit enter. (Note the "~")
  6. Empty the Trash, and restart your computer.

Now what browser should I use?

Safari is good and it's already on your Mac. It's fast and efficient. If you need a Chromium-based browser, use Brave or Vivaldi. Firefox has pretty noticeable pointer input latency which (I, the author) am pretty nitpicky about, but other than that it's fine. (Mozilla are a bunch of short-sighted dopes for firing the Servo team. If the Servo team regroups, I'd be inclined to recommend anything they make down the road).

What's the deal with Keystone anyway?

Wired first reported on Keystone in 2009, when Google put it into Google Earth. It has a long history of crashing Macs by doing bizarre things that shouldn't be necessary for auto-update software to function.

To all the good people at Google who work on Chrome: something is going on between the code you're writing and what is happening on people's computers. I hope you can track it down and give us an honest postmortem.

FAQ

Just restarting probably fixed it.

No, the issue persists across restarts, no indexing/applications running, etc, and is otherwise completely unexplained. Nothing obvious appears in Activity Monitor, and many people have meticulously tried to troubleshoot to no avail (obviously including restarting), and the only thing that immediately and conclusively addressed the issue was removing Chrome & Keystone.
