Bird process

I had this issue on two computers, an iMac and MacBook Pro. I had to make certain all iCloud info was shut off in preferences and the restart the computers. (I am running Sierra). The difference was amazing. The background process Bird never runs now - I check regularly with Activity Monitor - and both machines are lightning fast compared to what they were. Also, that’s why I use Dropbox.

Hope you get it fixed.

Bird, as you already know is a file associated with iCloud Drive, is it causing a problem?

Then kill it in Avtivity Monitor.
