Over the weekend Loren Brichter wrote about Google Chrome and how it makes your computer slow even when it’s not actively running. There is a website going into detail called chromeisbad.com. What’s going on?
Google Chrome installs something called Keystone on your computer, which nefariously hides itself from Activity Monitor and makes your whole computer slow even when Chrome isn’t running. Deleting Chrome and Keystone makes your computer way, way faster, all the time.
- Users aren’t told that the updater is being installed, nor given the option to decline.
- The update software has an aggressive update cycle. As Guilherme Rambo of 9to5Mac discovered, it checks for updates every 3623 seconds, or every hour and 23 seconds.
Mr. Brichter and others on Twitter say they noticed their Macs performed much faster after deleting Google Chrome and Keystone, although “Google Chrome as a resource hog” has long been a thing. But it seems Keystone in particular may be the secret.
Mark Chang, the project manager for Google Chrome, said Keystone only runs (at low priority) when it has tasks to perform. Check your system logs for GoogleSoftwareUpdateAgent as a user or GoogleSoftwareUpdateDaemon as root. The team isn’t aware of issues that would lead to high CPU usage for Keystone.
The good news is that Google Chrome isn’t the only browser available. Apple’s own Safari is a good choice, and other alternatives include Mozilla Firefox and Microsoft Edge. Mr. Brichter provides instructions on how to fully remove Chrome and Keystone from your Mac.
