i've just updated to OSX 1.7.2 on my iMac and MBA and to iOS5 on my iPhone 4S and iPad 2. Everything basically works well except the iCloud photo stream on my mac.
iPhone and iPad play well and push and pull fotos from the photo stream.
On the mac i can't activate the photo stream. I've updated iPhoto and Aperture but when i try to activate the photo stream it says that it's unable to reach the photo stream. I've already logged out from i cloud and re logged in again but that didn't help. iPhoto and Aperture are the latest versions.
Anyone with an idea?
Addition: Activation works well on another iMac with another iCloud account from my girl friend (in the same local network), i've also double checked little snitch isn't blocking anything.
Addition 2: It also works on my MBA with the same iCloud account that doesn't work on the iMac. Weird,
