Unit 7 Hands-on SoccerTwos.app appears damaged on Apple Silicon

[sgoodfriend]

This is after running the mlagents-learn command:

❯ mlagents-learn ./config/poca/SoccerTwos.yaml --env=./training-envs-executables/SoccerTwos/SoccerTwos.app --run-id="SoccerTwos" --no-graphics

Hey there :wave: , did you run this: or Mac you need also to call this xattr -cr training-envs-executables/SoccerTwos/SoccerTwos.app to be able to run SoccerTwos

[sgoodfriend]

I had not. After running xattr it worked!

[lsdxp]

what should happen after running xattr? I tried that also but it seems i am still getting the above error.

ok, after running xattr to clear, then you need to start the application in the folder, then you shall see the unity environment window, but when i tried to start train, it prompts to start another SoccersTwo and failed

This is possibly irrelevant, but this is my directory structure when I got it to work:

I have the same folder structure. I find my issue is because my macbook is an old one.
