When I login to my MacBook Air, I now get this error message about Photostream: "Photos for iCloud account "xxxxxxx@mac.com" cannot be accessed. Review you account information in System Preferences." I review my preferences

Same problem.

I suspect this has something to do with Apple providing me a new "@icloud.com" email address to go along with my "@mac.com" and later "@me.com" address. My Apple ID is still "@mac.com", so I presume I still need to log in as "@mac.com" in my user Apple ID settings.

Looking under "About this Mac" and then under "Software Installations" I believe the issue is:

iPhoto 9.4.2 installed 11/8/2012

Aperture 3.4.2 installed 11/8/2012

OSX 10.8.2 and thus using the App Store for software updates.

Yes, this issue has also appeared for me since I installed this update.

I have had the same problem for many months now...What can we do?

Log out of iCloud in the System/iCloud preference pane and disable Photo Stream in iPhoto's Photo Share preference pane. Then log back in and re-enable, respectively. That should jump start Photo Stream.

OT

I have the same problem!! I tried all possible solutions, nothing solved the problem. This issue is quite serious and for me it seems to be huge. I just want my photostream back, I want to sign in, I want to use it the way I did before... but I constantly get the same message as written above. Anyone out there, who could help us with this problem???

That would be so great!!

That erased all my icloud info (except my contacts). is there an eaiser option for this. Now I have to redo my calendar and all that. icloud is wasting my time.

you deserve the points!!

All of your info will reappear when you sign back in.

They came back when you logged back in as Csound1 mentioned, didn't they? Are you backup and working OK?

I had the same problem. Then, i remembered that the problem occured after i opted for alternative xxx@icloud.com id.

For photostream on mac, i had icloud account setup as xxx@gmail.com which is my apple id. so, i logged out from my xxx@gmail.com id from mac. and then entered xxx@icloud.com id under accounts in my mac and guess what photostream started working again.
