MacOS ARM64 version not launching

[jrupinski]

Summary:

Launching via console or directly (after granting executable rights) doesn't launch the app on Mac ARM64; it's killed instantly instead.

Warning about installingdotnet wasn't mentioned as well (it did show when I tried running the x64 version).
Let me know if I can help with any further information!

System information:

  System Version:	macOS 26.0 (25A354)
  Kernel Version:	Darwin 25.0.0
  Chip:	Apple M1 Pro
  Memory:	16 GB

Expectation:

• Install dotnet
• Grant executable rights to repackinator
• Launch ./repackinator, UI launches

Actual outcome:

• Install dotnet
• Grant executable rights to repackinator
• Launch ./repackinator, Terminal returns:

 [1]    5482 killed     ./repackinator

I followed the same steps on Linux (Steam Deck) - install dotnet, grant rights, run application - and it works as expected.

Output:

➜  ~/Downloads/Repackinator-osx-arm64 ./repackinator
[1]    5482 killed     ./repackinator

Same thing happens after I installed dotnet (brew install dotnet) + echo 'export DOTNET_ROOT="/opt/homebrew/opt/dotnet/libexec"' >> ~/.zshrc.
