We know that iOS 11 marks the end of the road for legacy 32-bit apps and now we’re learning about Apple’s new 64-bit requirement for Mac apps.

In an advisory on Dev Center yesterday, the Cupertino giant announced that macOS High Sierra will be the last macOS release to support 32-bit apps “without compromise.”

Apple originally said at the Worldwide Developers Conference that macOS apps submitted to Mac App Store must support 64-bit computing starting January 2018. The new advisory states that Mac app updates and existing apps must support 64-bit starting June 2018.

“If you distribute your apps outside Mac App Store, we highly recommend distributing 64-bit binaries to make sure your users can continue to run your apps on future versions of macOS,” reads Apple’s note to developers.

In a separate notice, the company reminded developers to submit updates to their 32-bit apps because iOS 11 is 64-bit only. ”Support for 32-bit apps is not available in iOS 11 and all 32-bit apps previously installed on a user’s device will not launch,” reads the note.

Two days ago, Apple asked developers to update their product pages for iOS 11’s redesigned App Store.

    Great product placement 🙂

  • This makes sense with iOS, but not with macOS. There are a LOT, and I mean a frickin’ lot of old Mac apps that have not been updated. Games as well.

    EDIT: By apps, I mean programs, 3rd party programs.

    • Actually this makes sense to do for a lot of reasons. For instance if you look at why Windows 10 requires more than double the storage even though it has significantly less features than MacOS out of the box it’s primarily because of all the hardware it has to support and everything required to make things backwards compatible.

      The more you have to support the slower, more complex and more bloated the OS becomes. Periodically trimming out support for older processors is a great way to keep things lightweight and fast for the most possible people. It’s exactly what happened back in Snow Leopard and personally I’m looking forward to it happening again 🙂

    This is where apple is wrong

    • How so? I’ve seen people talk about Snow Leopard as being one of the best releases of MacOS in recent history not because it had any big new features, but because it became smaller, faster and more stable by a noticeable about. How did they pull that off? They dropped support for older processors. Curious why it’s a bad idea this time around.

  • Jose Rivera

    Does this mean Apple will drop support for certain Mac models come next year when macOS 10.14 or 11? (If we even move past 10) I have a feeling that macOS 11 (or 10.14) will be like iOS 11. 64bit only.

  • So Young

    If Apple wants to shoot on their own feet by dropping support of many, many older programs and games and want more of their users to install and use windows way more frequently than macOS, this is exactly what to do.

    • It seems everyone around here has forgotten that Apple has always treated their desktop OS like this and it has survived just fine so far. Or does no one else remember all the processors that were no longer supported as of Snow Leopard?

      • Caspian Will

        Who cares about the CPU, we’re talking about software here? The OS can require the latest CPU but your games will still work on Windows, not on Mac, because Apple logic. Stop talking about old hardware when this is about old software.

        I wonder how many people would cheer at the inability to watch classic movies for being “old” and not “remastered” because that’s exactly what’s happening here but with software.

        Also, soon even Linux will overtake Mac market share and you call it doing fine?

      • LOL, I think you missed the entire point. The person I replied to was essentially stating that if Apple removes support for 32 bit apps people would lose tons of old apps and flee in droves to Windows. I brought up the CPU just to point out that Apple has done this before (literally cutting support for every app ever made before a certain year) and survived. And not only did they survive, many people think of Snow Leopard as one of the great updates of the past.

        As for the rest of your comment. Games are a silly thing to comment on. If a game has been built around technologies like DirectX it will not run on MacOS because DirectX is a Windows Designed graphics library. It’s not that Apple can’t run games. It can and does very well. But currently most developers opt to use tools that are not compatible with Apple products. And Microsoft is not about to share their DirectX technology with the competition.

        And finally your comment on movies made me laugh a bit. Or do you still use VHS tapes? I mean, I have to ask… Why on earth do you have a Mac if this bothers you? Apple has been known for doing this stuff for years. Unlike Microsoft they don’t hold onto dying technologies, but are all about clearing out the old to make room for the new. Or did you not know this when you got your Mac?

        And as for the market share, it’s been steadily growing since 2006. If linux is also growing just as rapidly that means that Microsoft must be bleeding users and that’s good news for the competition 😛

        Not everybody is an Apple fagboy. Uh, I mean, “fanboy”.

      • I’m not sure I understand the point of your comment. There’s obviously lots of people with lots of different needs and/or tastes.

      • Aleph Knull

        You misspelled “customers”. You wrote “Apple has always treated their desktop OS like this”, when I am sure you meant to write “Apple has always treated their customers like this”.

      • Actually, if I were to go back and edit it I think I would change it to say products instead of desktop OS.

        Historically Apple has never treated its own products like enshrined things to be protected at all costs but has often led the way in the tech world to change and update things to new standards even if it sometimes means a painful transition as the old is cleared away in preperation for the new.

  • Matti J O

    So there will be a need for a separate Mac for running old programs. For the gaming purposes I’m switching to PS or Windows.

  • Donald Feuer

    OS 11!!! The new apple begins, in 3!

    • Aleph Knull

      Are you confusing iOS 11 (as mentioned in the article) with macOS? The next release is macOS 10.14, not macOS 11.
