How to find which apps on your Mac are 32-bit

“Apple has been warning developers for some time that 32-bit apps would be deprecated on macOS, as they have already been on iOS. macOS High Sierra is now displaying a warning whenever you launch a 32-bit app, informing you that the app is ‘not optimized for your Mac,'” Kirk McElhearn writes for Kirkville.

“If you click OK, the app will launch, and if you click Learn More, you’ll be taken to an Apple technical document explaining this change,” McElhearn writes. “You can continue to use these 32-bit apps… [but] it’s a good time to check if the apps you depend on have updates available.”

McElhearn writes, “There’s an easy way to find all the apps on your Mac that are 32-bit.”

MacDailyNews Take: Hopefully, if you’ve got any older 32-bit apps upon which you depend, there’s already a 64-bit version available or in development!

  1. I am going to miss DVD Player! It works on every DVD, VLC unfortunately does not.

    It’s hardly any work at all to recompile into 64 bit. I could be done in a few minutes if Apple wanted to.

  2. My System Information > Software> Applications times out and only lists: “The plug-in did not respond quickly enough while gathering this information.”
    Anyone know of a plist file I can modify to lengthen the time System Information.app Applications plug-in scans my 700+ Applications?

  3. I’ve got about 700 executables (processes, apps) that are 32-bit. As usual, it’s Adobe who’s the biggest foot dragger. I’ve got 7 Adobe applications that remain 32-bit. Otherwise, I’ve got ~10 older applications I use that need updating.

    Of my 700, perhaps 10 are irreplaceable and unlikely to be updated. The saddest of them all is Spell Catcher upon which I depend all day, every day. It’s brilliant, excellent, profound, and its developer died six years ago. You can’t buy it any more, let alone get updates. It will be my prime reason for not updating to macOS 10.14 when it arrives. (;_;) Boohoo.

    As ever, it’s amusing to note that Apple has a number of 32-bit processes/app they have yet to update. Eat your own dog food Apple! Better catch up with yourself!

    The biggest casualties among the non-critical 32-bit apps are several games. I know very well that they won’t ever by updated.

    And of course it’s going to be a big PITA having to pay for 64-bit versions of apps that have yet to be updated, those from the slow boat developers that should have known better sooner. *sigh*

  4. I am embarrassed to admit that I am still using iWeb (the few sites I create are simple and lend themselves to the graphic driven page layout). Another confession is that after giving Lightroom a trial, I still prefer Aperture. So, can I create a partition that has a 32 bit capable OS and my oldie-but-goodie apps? It seems like the answer should be yes, but I am still trying to recover my iPhoto database after Photo got its hands on it. Thanks.

  5. All the apps that are shipped with the OS will likely be delivered with the first 64-bit only beta. If DVD Player is still included, it may get updated. I’m guessing they don’t include it anymore, though.
