Hello,

Since a few versions of Defold (I couldn’t say when), when I’m building a macOS bundle on Windows 10, I encounter this error in the _Build Errors_ console:

> Cannot run program “C:\Users\fulura\AppData\Local\Temp\3330806739543307014\x86\_64-darwin\strip\_ios”: CreateProcess error=193, %1 is not a valid Win32 application

However, the bundle seems to work, as I played the game on macOS with the generated files without any issue.

I’m not sure if this is a critical issue, but I just wanted to let you know.

Ah, sorry about that. I think @JCash had solved it recently and it will be included in the next release.
