Trying to figure out how to see activity happening while iCloud Files is syncing. The macOS Console application shows messages from cloudd, but nothing very useful:

enter image description here

The Activity Monitor does not show cloudd nor other process transferring much data either.

I'm looking for log files under /var/log or ~/Library/Logs, but cannot find anything.

Is there any log file that could be used with tail to see iCloud sync activity in real time?


You can use brctl like brctl log --wait. When it stops showing messages it's synced.

There seems to be a lot of options and little information. This blog post might be helpful

    As far as 2020 and MacOS Catalina --wait parameter no longer exists. – Dawid Moś Feb 1 '20 at 14:51

    You can use brctl log -w --shorten on Catalina – intagli Feb 29 '20 at 17:06
