Every day Creative Cloud informs me that an update is available for Photoshop. I download and all seems to go normally. If I check in the help menu in Photoshop it says there is an update available. I can download this and the computer goes through the normal procedures of downloading, asking me to quit PS and subsequently updating. If I then open Photoshop and check for updates it again tells me than update is available.
I am currently running v 14.2 x64 on an iMac running OS X 10.9.1.
