New iMac 2021 - Can't play anything... Why?

[mrs_doodykins]

Hey everyone,

I just got my new iMac 2021, but I can't play any new game nor any of my old games that used to run on my former Macbook Air.

The new iMac comes with Big Sur. I also checked the box regarding the Betaversion testing, but still nothing. Whenever I try to start or install a game it shows me a note saying that my platform is not supported (in German, I don't know what the English equivalent says).

Is it not possible to use steam on the new iMac? That would be shocking... can't find any helpful stuff via Google ...

Help plz? Thx!

Additional info: I migrated my old data via backup to the new iMac, but I re-installed steam twice. All updates were downloaded, but I always get the same message that my platform is not supported :'(

Do these games have a 64Bit version available? Apple dropped support for 32Bit apps entirely and they can no longer run.
This affects MANY games for Mac OS.

This should be the answer, as the ARM architecture of the M1 doesnt affect the game compatibility. Any game running on a "normal" (x86) mac will run on ARM aswell. The only problem will be slightly longer waiting times at the first launch due to rosetta.

Thx for the suggestions!

I fixed the problem by using the Clean My Mac software to get rid of all the backup information for Steam from my old laptop so that I could re-install Steam without it using old data left behind, now I can use Steam again as usual *sigh.of.relief*. Before I used the CMM software there must have been residual data left from the backup.

Thx again, maybe this entry will help someone else with a similar problem. Kudos!

First time you start a x86 game on Apple Silicon it will be translated via Rosetta 2 so sometimes it will take time before the translation is finished and you can play.

I just joined Steam and purchased a game and it won't run. I'm running Big Sur on my iMac and the error says it won't run 32 bit app on Catalina. I don't know what to do.

You ask Steam for refund. You can't run 32-bit games on Catalina, Big Sur or Monterey. Unfortunately Steam doesn't always show the right info about this. Despite the warning on the game page some games are 64-bit and will run, like Metro 2033 Redux and Last Light.

Drag your 32-bit applications from your real Mac into the virtual Mojave system. Double-click them to run them. If you're running Mojave and not an earlier version, you'll see the familiar pop-up warning that your 32-bit is not optimized for macOS and will need to be updated. Ignore the warning.
