WebGl no skybox is showing up (Mac)

Pretty much what the question says. I’ve exported the game to a mac app and it works fine, but with WebGl export I get no skybox.

I have a skybox in a webgl build. It works fine on all browers except for Firefox on a Mac (it’s fine in firefox on Windows). It shows as black, which is noticeable because the clear color is light grey.

I have no answer for this, but wanted to join you asking the question.

Thank you Barry, that was exactly what I had (Firefox on Mac) had a friend test it on windows which it worked fine on.
