| The linked source is directly from Adobe and directly contradicts the claim that "you need 13.1 to launch in 64-bit." The source says: > Photoshop CS6 and CC only install a 64-bit version on Mac OS. Further, it says: > Photoshop CS5 installs a version that can launch in either 32 bit or 64 bit when you install on a 64-bit version of Mac OS (Mac OS X 10.5 or later). If CS5 install can launch in 64-bit, it wouldn't make sense for CS6 to be 32-bit only from the first version. Even further, I know from personal experience that your claim is highly unlikely. This is a screenshot of Photoshop CS5 (12.0.4) running in 64-bit on my machine (High Sierra). Noticed it says "12.0.4 x64." https://imgur.com/a/nCTghcy I am not sure of the source of your information, but it's simply incorrect. Edit: This is another article directly from Adobe. It says: > On Windows, both Adobe Photoshop CS6 and Adobe Photoshop CS6 Extended have the option to run natively in either 32-bit or 64-bit editions. On Macintosh, only a 64-bit edition is available. https://helpx.adobe.com/photoshop/release-note/release-notes... |
I have no reason to believe that’s not true.
I think it’s quite possible that when Adobe says “64-bit” they’re not saying exactly the same thing that Apple means. I’m no expert with macho binaries and MacOS library linking.
