I was wondering why my disk space was reducing pretty quickly on my Mac, and it turns out my
~/Library/Caches/com.apple.bird/ directory was 92GB in size! Inspecting some of the larger files, I notice that it has a WhatsApp header, which suggests that these are my WhatsApp iCloud backups.
There obviously seems to be some kind of bug as I have files, one per day, from sometime in April. They all start around 800MB and grow to 2GB in size. Each.
It seems like there are other files there too, and I wasn’t sure if deleting it would just make sense. The solution?
System Preferences -> iCloud then toggle iCloud Drive off. There is a warning about how it will delete all iCloud documents from your Mac. Its all good considering this is supposed to be saved in the cloud right? Restart it, and voila, you see the directory go down to 0 bytes.
Something up with the
bird daemon? I don’t know if
brctl would help in any way, so I’m happy there’s an easier way to recover lost space.
