So I did the 10.7.2 update, did all of my iCloud login and whatnot, and today when I booted my MacBook Pro, I noticed my network activity skyrocket. For a good 15 minutes straight, I was pulling about 1.0 mbps. I discovered it was due to the iDisk file sync agent. I went to activity monitor and killed it. Fixed the issue, but i'm wondering if anyone else has had this issue.
