Yes, happened to me for almost all game of macOS bulids uploaded on itch. Not sure it has to do with zip algorithm nullify the permission set before compressing. I didn't go far trying to fix the issue.
I can't seem to replicate this issue. Then again... I have not updated the is on my 2016 MacBook pro since... Well... 2016. So it may be that newer versions have that issue. Once again, thank you very much for your comment. If you don't mind, I'd like to add that point to the installation instructions.
