Might be worth mentioning a bit about filesystems:
- Apple HFS + and APFS are neither read nor write from Windows. These FS's are required for Mac things like booting, and Time Machine.
- Win FATnn is read and write from Mac, but may be other issues. For example, file size limitation of 4GB (think movies).
- Win NTFS is readable by Mac, but Macs cannot write to them. <- Paragon provides drivers to make this work fr Macs.
- Win exFAT is read and write from Mac.
Remember that solutions like Paragon, which I believe are good, is only part of the answer. You still need to connect (such as wi-fi) and get access permissions to work on both sides.
