ALL .ts4script files show "corrupted" on Mac ARM - even after full reinstall

After patch 1.121 (Feb 3, 2026), no .ts4script file can load on Mac ARM (Apple Silicon).

Error: "Cannot start because the below file appears to be corrupted" Code: [60c399f9:29f00e76:00000000:4b0d852b]

System: MacBook Pro M3 Pro, macOS 15.5

Game version: 1.121.361.1220

Tested:

 - Official S4CL v3.19 .ts4script - FAILS

 - Minimal 1-command test script - FAILS

 - Multiple ZIP compression methods - ALL FAIL

 - Game repair - didn't fix

 - Full uninstall + reinstall - didn't fix

 - Deleted localthumbcache.package - didn't fix

 - Deleted GameVersion.txt - didn't fix

 - Feb 12 hotfix applied - didn't fix

The error code is identical for EVERY .ts4script file, confirming this is a game-level validation bug, not file corruption. Game works fine with an empty Mods folder. No script mods can be used at all on Mac ARM.

  • did that countless times, actually its the t4script, its a self written mod. I also tried with already available mods and it just doesnt work on mac.

    ekzxn8k53eww​ For support in mod creation issues, I recommend the resources in the Discord server Creator Musings. There is also a friendly, helpful community of experienced modders there, including modders who work on Macs.

    For support with solving file corruption problems on a Mac, please head to Mac tech support. 

  • It is not a mac issue though I am convinced its an issue from EA sports side because before feb 3 update from ea sports there was no problem

    ekzxn8k53eww​ We regularly see lost people here in Sims forums because they followed a Google link without looking closely, and you're saying it's related to EA Sports, so I wondered if it was a different game you meant to be posting for. 

    Please do this exact one-new-mod test:

    1. Drag your whole Sims 4 folder from Document > Electronic Arts to your desktop and rename it.
    2. Run a Game Repair in the EA App. (If you use Steam, the equivalent is Verify Integrity.)
    3. Launch Sims 4 and exit.
    4. Download one script mod to test. I recommend getting XML Injector from the Scumbumbo mod site for this, because I know the file is fine (I help maintain the Scumbumbo memorial site) and because it includes a test file for making sure it's being seen in-game.
    5. Start with New to test if your issue recurs.

     

    Let me know if that works.
