Mac Installer not working in mac version 12.6,12.7

[vaibhavopkey]

I'm working on a Mac installer using InstallAware Multi-Platform.Inside DMG file .app not opening in mac version 12.6,12.7.It Says "You can't open the Application app_name because this application is not supported on this Mac.

We do officially support macOS Monterey (in fact, in the best traditions of InstallAware; we do go a lot more downlevel than that on macOS, Mojave for example, is also fully supported - and looks really great with pop-up message boxes and such).

Can you please attach some screenshots of the error you are seeing?

Furthermore, can you please confirm if this happens on Apple Silicon or Intel hardware?

Last but not least, can you try to install InstallAware Multi Platform on those affected devices, and let us know what happens?

Many thanks!

This happens on Intel hardware. I have installed InstallAware Multi-Platform rtm.dmg, and it installed perfectly. I also tried installing rtm.arm.dmg, but I am getting the same error as I did with my installer.

I have attached some screenshots.

Thanks for those additional details - they have definitely helped pinpoint your problem!

You cannot run an ARM64 (Apple Silicon) binary on Intel, this is impossible. This is the same regardless of whether you're trying to run a setup built with InstallAware Multi Platform, or any other program file, such as Acrobat Reader for lack of a better example (we just recently finished setup capturing it on macOS and converting it's installer into an InstallAware Multi Platform setup, so that's just the first example that popped into my head here).

You could consider it a limitation of macOS, but generally you cannot mix CPU architectures like this, regardless of what operating system you're running on.

The other direction works, thanks to Rosetta on macOS, and Windows's WOW (Windows on Windows) and more recent emulation layers (so you can actually run Intel binaries on Apple Silicon and/or aarch64 Windows architectures). But that is the exception that proves the rule.

I used rtm.arm.dmg just as an example—I'm experiencing a similar error. When I used InstallAware Multi-Platform during the trial period in December, the .dmg I built worked perfectly on all versions of macOS. However, after updating recently, this issue has started appearing. Is there a setting change I need to adjust?

[JohnGaver]

You probably remember running the Intel version of InstallAware Multi Platform on Apple Silicon, which is supported through Rosetta.

Or, similarly, you built your installer using the Intel version of InstallAware Multi Platform, running either on native Intel or emulated by Rosetta on Apple Silicon; and your setups ran on both Intel and Apple Silicon.

Please understand that going in the other direction is flat out impossible. Even Apple cannot do it for you.

Thanks JohnGaver , Now it's working using Intel Version.

Yes if you want to support each platform on macOS this is the way to go.

And you can obviously deploy any payload you like.

And if you wanted to, you could even deploy native Apple Silicon payloads and native Intel payloads based on the underlying state of the platform obtained via the Get Native Settings command and a simple If command.
