High CPU usage of xcodebuild and IDECacheDeleteAppExtension after Big Sur upgrade

Hi all,

I upgraded to Big Sur v11.2 a few days ago, and Xcode command line tools popped up an upgrade, which I installed as well. The current Xcode version is 11.1 Build version 11A1027.

However, I have been unable to use my computer. There are 3 instances of `xcodebuild`, a `filebeat` and a `IDECacheDeleteAppExtension` running since the system starts. I have no idea what they are doing. They would eventually cause the system to force shut down in about 1-2 hours. I couldn't kill those processes, and when I do, the system would freeze. For example, if I kill them in Activity Monitor, AM would freeze, force quit, and cannot be opened again until I reboot. The same thing is I try to kill the processes in Terminal.

Meanwhile, everything is very slow on my machine. Tried first aid on the disk but no issue was found. Any suggestions?

Hello aroundghost and welcome to Apple Support Communities. It appears you are having some difficulty with processes associated with Xcode.

1) Start by doing a safe boot of the Mac. This will clear some cache files, turn off some system extensions and log-in items and give you a good foundation. After doing the safe boot, reboot normally and test.

2) If the issue persists after a safe boot, set up a new admin user account and boot into that for testing. Doing so helps you to isolate the issue to the system or the user data and ultimately resolve it.

You can find the steps to add a user here:

If these steps do not resolve the issue, as Xcode is a developer tool, you'll want to reach out to developer support.
