Leorik 3.1 macOS ARM doesn't start

[twoplan]

Hi,

the arm version of Leorik 3.1 doesn't start on my m4 mac running macOS 15.4.

Leorik 3.01-arm and Leorik 3.1-x86 work fine.

./Leorik-3.1 
zsh: killed     ./Leorik-3.1


lldb ./Leorik-3.1
(lldb) target create "./Leorik-3.1"
Current executable set to '/Users/max/chess/UCI/Leorik/Leorik-3.1' (arm64).
(lldb) run
error: process exited with status -1 (no such process)
(lldb) quit

Sadly I don't have a Mac to try that but maybe the executable is not "secure" enough for the OS to run it?

It could be in quarantine status and according to chat-gpt you could remove that by running

xattr -d com.apple.quarantine ./Leorik-3.1

Or maybe there's codesign issue? Then this might help:

codesign -s - ./Leorik-3.1

Let me know if any of this worked! :)

I had already removed the quarantine flags from the downloaded binaries. Along with granting the execution permission, this was enough for the x86 version of Leorik 3.1 and the ARM version of Leorik 3.01 to work.

However, the ARM version of Leorik 3.1 also required the step you mentioned, codesign -s - ./Leorik-3.1!

Thanks 👍, I've never had to do that before ... never stop learning. 🤓

Thanks for confirming that the Mac version work and how to get them to run! 🏅

I had the same problem with ARM version on Mac, but the non ARM works fine on Mac M4 silicon after chmod permissions. The ARM versions works after codesign. Not good at Unix so used Warp

AI terminal and it did the job for me.See attached file. Thanks

👍 👍 ...that AI terminal is really cool!
