REI Blackbook Compatibility

[Danny Overfield]

I am just entering the industry and appreciate any insight anyone can share. 

I have heard a lot about REI BlackBook and I am considering signing up but I am unable to find information on which operating systems it is compatible with.

I am currently using macOS but have considered switching to a Chromebook for it's versatility. Naturally, I want to use what will allow all essential programs to function optimally. Does anyone know what operating system will allow REI BlackBook, and any other "must have" programs to run without a hitch? I am also open to Windows if that means I'll have the least amount of issues.

Thanks in advance!
