I have just changed computers, and after installing Acrobat Pro 9 from the disk, I can't find updates anywhere. All the links to Mac updates only go back to 10. Also, my Help menu does not contain the traditional "check for updates."
I know there are updates--my current machine (Snow Leopard) shows version 9.5.5. I have no idea how I did it.
The un-updated Pro 9.0 seems to work fine with Yosemite (new machine), but I'd really like to get it up to date as much as possible.
