Intel, Universal 1 or 2 apps

If I read things correctly with the introduction of MacOS 27 it will be the end of Intel apps. (Some sites say MacOS 28).

My understanding is that if the app is designated “Universal” it will work in MacOS 27 and beyond.

Again my understanding is that “Universal  1” was for PowerPC & Intel and “Universal 2” is for Intel & ARM.

As my M1 is running Rosetta 2 ( I presume) the “Universal” and Intel designated apps are working.

When Rosetta 2 is dropped in MacOS 27 will these ‘Universal” apps still work if they are designated just  “Universal” or will they need to show  “Universal 2” or ????

iMac 24″, macOS 15.5

So I'm a bit confused on the Intel/silicon issue. I see recommendations that installing Rosetta 2 will enable the use of Intel-based apps, but elsewhere I see that Rosetta support is to be dropped when a future version of MacOS is launched.

Universal 1 and Rosetta 1 is roughly twenty years back, and no longer relevant.


Universal 2 is current, shows as Universal, and is relevant for old app versions and for effectively if not actually unmaintained apps.


Support for Intel x86-64 apps is going away in macOS 27, except for a few specifically unmaintained games.

So far I'm not seeing much evidence of even majors (Amazon, for example in their desktop Music app, Intel only, offering a silicon-compatible version? Can anyone clarify? I already have several notifications popping up reporting that some of my apps will need to be updated...

Which apps, and do those apps have newer versions?


If Amazon’s desktop music app is not updated for instance, don’t update to macOS 27 when that arrives, and then check with Amazon for updates or alternatives for macOS 27.


Some of the printer vendors haven’t updated their apps in some years, and some of those apps might even be unnecessary for AirPrint / TWAIN / ICA printers and scanners.


These macOS 26.5 app notifications are presumably all trying to warn people about their old apps before the macOS 27 betas arrive, and break the old things.


Also probably to encourage the vendors to update their apps for Apple silicon Macs, that having first been released back in 2020.


Or to not rush a macOS update when some critical app hasn’t been updated or replaced.
