Re: photostream not working on my mac

I do not know if anyone ever runs into this issue anymore, but the Apple Engineers helped me fix this recently.
They had me do the following:
Turn off Photo Stream in your user account:
Quit iPhoto
Goto System Preferences > iCloud > Uncheck Photo Stream.
Close System Preferences
Then deleting the entire ~/Library/Application Support/iLifeAssetManagement/ directory.
Open Terminal and type in cd Library
then type open . (open space period)
navigate to Application Support and delete the iLifeAssetManagement folder.
quit terminal
Then turn photo stream back on in their photo library.
open iPhoto and click on Photo stream in the left column.
enable photo stream.
It will take some time to download the cached photos but this resolved my problem of having 0 display and no photos in the "My Photo Stream" area when any of my other devices showed new photo stream photos without any problems.

Re: Shared albums won't show up on new Photos on Mac
in response to mwbaker210
Guys,
If you are still facing this issue after rebuilding, try this:
1. Close Photos
2. Go to System Preferences, iCloud, Photos and disable “My photo Stream” and “iCloud Photo Sharing”
3. Go to folder /Users/YourUser/Library/Containers/com.apple.cloudphotosd/Data/Library/Applicati on Support/com.apple.cloudphotosd/services
4. Delete com.apple.photo.icloud.myphotostream and com.apple.photo.icloud.sharedstreams folders
5. Enable “My photo Stream” and “iCloud Photo Sharing” again.
6. Start Photos. After a while, the shared photos will start coming.

Re: Photostream not updating on Mac Photos
in response to leonfromearth
Helpful
I had this same issue. I fixed this by:
Closing Photos.
Opening Activity Monitor.
Killing the process titled "Photos Agent"
I opened up Photos again, and my Photo Stream immediately updated.
