process "bird" taking up to 140% of CPU and running constantly

Mac OS X 10.10.1 Yosemite/iMac mid-2011


My iMac is really slow to start-up, to run, and to have applications run. I have 32 GB memory, 113 GB hard disk capacity and it has never been slower in its life. There is a process called "bird" that is running almost constantly whenever I run Activity Monitor and it is taking up to 140% of CPU time. What is "bird"? Why is it running constantly and eating up so much CPU time? Why is my iMac so slow running Mac OS X 10.10.1 Yosemite?


Other issues on my iMac include: Software Update is supposed to be updating and installing updates automatically and it is not. When I log in, I see a blank white screen with an apple logo and a progress bar below. It takes forever for the progress bar to get 1/4 of the way across, then the screen flashes and the progress bar finishes the remaining 3/4 really fast. And then once logged in, it takes forever for my dock icons to appear, and my iMac hard drive is chattering like crazy even though nothing is running yet. Whenever I launch Safari I get a progress bar in the address field that goes 1/3 of the way across and frequently hangs. And then just nothing. All of these issues never happened before Mac OS X 10.10.1 Yosemite. Is anyone else experiencing issues like this? How did you solve them?

iMac (27-inch Mid 2011), OS X Yosemite (10.10), Safari 8.0

The process is linked with the iCloud sync.

Select System Preferences > iCloud and uncheck the iCloud Drive option.

Once it’s enabled iCloud Drive starts working automatically, syncing data between your devices in the background (slowing your iMac down). Unlike the first version of iCloud, iCloud Drive can be be accessed in the Finder like other folders. You can store any type of file in iCloud Drive provided it is less than 15 gigabytes in size. When it’s enabled, it will show up in the side column of a Finder window. iCloud Drive is not as advanced and widely accessible and supported as Dropbox, but it’s useful if you work and share documents between your iOS and Mac devices. The service should improve further.

Thanks for the info. I had stored some files on iCloud Drive but I really do not have to have them there. I'll try disconnecting iCloud Drive and see if performance improves. I hope you are correct and Apple gets this working better because it would be great to use it if it did not impede performance so much.
