Brush files compatible on one computer but not a second (same PS version)

Hi guys!

I'm sure I've missed something quite obvious, but I'm wanting to transfer some individual photoshop brushes from my work computer (mac) to my home computer (windows 10), I'm using Photoshop CC 2018 on both.

I'm able to "export" my preferred selection of brushes on the Mac, creating a new abr. file, however when I transfer this new abr. file to my Windows computer the brushes won't load, I get an error message saying they are not "compatible with this version of Photoshop" despite both versions of Photoshop being the same and up to date..

I don't think it's the difference in operating systems as I am actually able to import the original brush files used on my Mac to my Windows computer, which include the exact same brushes I'm attempting to transfer (such brush files just includes close to 100 brushes and I'd rather just import the few I want rather the whole lot).

So I'm assuming there may be an issue with the way I saved the files?

Basically all I did was I created a new brush group on my mac, moved my preferred brushes into that group and exported the group. Though I doubt it's as simple as that as that certainly didn't work haha.

Is there any way to transfer a brush selection from one computer to another using the same Photoshop version?

Thank you in advance!
