What is Google KeyStone?

When you install Google Chrome on your device, it also installs an update manager service called Google KeyStone. KeyStone regularly checks for the latest version available for Chrome and other Google services installed on your device. If an update is available, it will download and install it to keep your browser up to date.

But unlike other update managers that run when you launch the app, KeyStone always runs in the background even when you are not using Chrome. On Mac, KeyStone somehow affects WindowServer which is a system process causing a spike in CPU usage. The result is your Mac slowing down and lagging.

A user shared his own experience when struggling with KeyStone and how deleting it not only resolved the issue but also improved the performance of his old 2015 MacBook. You can read more about it here.
