Hi!

MacOS Steam is giving me "invalid platform" when I attempt to install

I appear to meet the minimum requirements, is there anything in my spec that's preventing installation, or is this a Steam issue? Any known workaround if so?

MacBook Pro (15-inch, 2017)
2.9 GHz Intel Core i7
16 GB 2133 MHz LPDDR3
Radeon Pro 560 4 GB
