It is very unfortunate that you are not getting the latest Ps updates.
Please confirm your Ps version from Help->About Photoshop and provide us with the following logs.
You can find them at:
Program Files(x86)\Common Files\Adobe\Installers
/Volumes/%Volume Name%/Users/%Username%/Library/Application Support/Adobe/AAMUpdater/1.0
You can zip all the files together and send us through mail. This would help us in finding the root cause.
Appreciate your help. Apologize for the inconvenience.
Thanks for your prompt reply to my issue with updating Photoshop CS6. I found the AAM Logs quite easily, but ran into a snag while looking for the Installer in the Library\Logs\Adobe\Installer, however I am sending you what I did find. Hopefully, this will help you find out why I can't update Photoshope CS6. If it will help you I did transfer my Creative Cloud Student and Teacher Edition to the Photoshop Photography Program. Thank your for your help and if I need to delve further into my Mac for anything else that will help, please let me know.
