FAT32 would actually work on both platforms. SxS cards are FAT32 so if you’re just copying the BPAV over FAT32 would work.
If you’re on an Intel Mac you can install Windows with Parallels or VMWare Fusion.
The alternative is that there are some 3rd party Mac utilities that may allow you to write to NTFS on Mac.
I believe NTFS is read only on the Mac.
