I have saved songs I write on my BIAB for Windows and loaded them on my Mac with BIAB.

Adding to Mike's comments, even if you both have the same level of purchase (example UltraPak), remember that the Mac version 2021 is not yet available, so don't include any of the 2021 styles because they likely contain some 2021 RealTracks your friend could not have.

There is an interesting utility in Save Special to email a song AND the style files used. This would not help if the recipient did not have all the RealTracks you used in that style, but it's partway there.

Assuming you've worked out all of the above, then you can consider freezing the tracks before you send it, if you want your friend to hear the same arrangement and same solo.
