Twinmotion Datasmith Exporter not working for Archicad 26 Apple Silicon

Well... basically what I said the subject.

Twinmotion Datasmith Exporter not working for Archicad 26 Apple Silicon

Probably not expecting an updated add-on for a few months. And to add insult to injury, I only found out "after" I uninstalled the MacTel version.

Anyone else experiencing this with the Apple Silicon to Twinmotion export? ...or did I do something wrong?

I managed to downgrade my iOS from to Sonoma, yet not even that brakes the spell...

epic games launcher still in update loop of turning up and closing down... sigh

Here, it is working OK with M1 Max as well as M3 Max MacBookPro and macOS 15 Sequoia.
But I also recommend the FBX workflow that Rex already explained, as Epic needs several months to upgrade the Datasmith plugin to the current version of AC (it's about 28 now).

I am really not sure what might be preventing install and update. I have installed as promised whole thing  just now. https://www.twinmotion.com/en-US/download Epic launcher from here. At installation it updated itself with 300MB and then opened in less then 30 seconds. 23Gb download for latest Twinmotion and it’s all up and running. Verifying Twinmotion took about 5 minutes. And it appears to have stopped. This is when you have to press launch again in Epic Games and it worked fine. My only thinking in your case would be that Rosetta translator has failed to convert from Intel based Twinmotion or you will have to delete all associated files from Epic and start fresh.

finaly found the solution described here: https://forums.unrealengine.com/t/how-do-i-fix-installer-is-stuck-on-a-update-loop/412137/10

Solution:
1.Uninstall Epic Games Launcher and reinstall it
2.After you open the .dmg file, drag it onto your desktop
3. Make a new folder called “Epic Games Launcher” And make sure it’s spelled exactly that way
4. Right click on the original Epic games installer and click show package contents
5. Copy the contents and past it into the Epic Games Launcher folder that you just made
6. Delete the epic games launcher app and eject the .dmg file
7. Rename the Epic Games Launcher to “Epic Games Launcher.app”
8. Click on add and it should run normally

it works... thank you all!

I am glad it got solved for you. That was one odd way of clearly dealing with some corrupt code in Epic Launcher App but it worked so lets hope  Twinmotion works fine as well.

it all works yes - since i just bought my new MBP M3 PRo, i briefly tryed to walk through some preset project from twinmotion and i was expecting smoother movement and clear upgrade from my windows computer from work (ryzen7 5800x, rtx 3060Ti, 32Gb...) - hope, other scenes will run smoothly...

Based on response I had from Epic Games support, developers have now advanced in preparing Twinmotion to become Apple Silicone version. Lets hope that will significantly improve rendering speed from what is even now relatively good performance even with Intel based software version.
