I'm running macOS 13.4 (22F66) on a MacBook Pro 16" (2019) and the process bird (which seems to be iCloud-related) keeps running at very high CPU utilization. It also makes Xcode unresponsive until I force quit bird, after which Xcode resumes operating but bird immediately restarts and shoots back up to high CPU utilization.

It also seems to write a ton of data, as seen by the Bytes Written value in Activity Monitor relentlessly climbing.

My ~/Library/Caches/com.apple.bird cache is merely 160 Bytes large. The size of this cache is not my issue, the CPU hogging of the process is.

bird process takes up 95% of CPU

Now I've seen elsewhere that I can see the log via

brctl log -w --shorten

but I don't know how to interpret that log, and despite many mentions of bird taking up a lot of resources, I can't find any thread in which someone actually resolved this problem.

I'd appreciate any help here. How do I make bird chill out?

The general solution for problems with iCloud processes is to sign out from and back in to your AppleID.
