I've just had a message from Apple after installing their latest update to High Sierra 10.13.4 saying that my Adobe products that are still at 32-bit will not run on my computer after future updates of the operating system. They advise that those apps need to be updated from 32-bit to 64-bit. Do you have an update so that I can continue using my Adobe apps?
Which Afobe products exactly?
Acrobat (for which forum serves) DC is indeed a 64-bit application under MacOS. All current Adobe Creative Cloud applications for MacOS are also 64-bit applications.
However, there are a few remaining background service processes that are not yet 64-bit. These are scheduled to be moved to 64-bit within the next year.
HOWEVER, in the meantime you can safely ignore the warning message. There is no loss of functionality or performance based upon this. By the time MacOS does prohibit 32-bit applications, the updates will be available from Adobe.
Why do my Win10 PDFs say Adobe Acrobat Reader DC (32-bit) in the top bar when I'm on a 64-bit machine? Thanks.
The two things are not related. Adobe is starting the release of the 64-bit version of Acrobat for Windows in limited regions, but for the moment it's still 32-bit for almost everyone. Soon enough you'll get an update, but for the moment you don't need to worry about it. A 32-bit app can run just fine on a 64-bit machine.
