I might be having the same problem. Ever since installing the Xcode 12 GM, I have two processes, "***" and "pkd" which are eating up 80% CPU each. The computer is completely unresponsive, and frequent beach balls. Numerous apps are Not Responding and need to be forced killed. Even after rebooting, it resumes.
Near top-of-the-line 2019 MacBook Pro 16", i9, 32 GB of RAM running Catalina 10.15.6.
My Console was filled with messages like this:
Code Block error 09:32:52.330888-0600 pkd Failed to create LSPlugInKitProxy object (after sorting) for <private> (853216) |
The only way I was able to resolve it was to rm -rf /Applications/Xcode.app and reboot, and even then I had to reset the SMC.
I tried re-installing Xcode 12 GM last night and it went back to the same thing. I'm going to try again this morning but I'm pretty nervous.
Are you seeing those same two processes @gtrichar?
