Q: What drive format works on both Mac and Windows?

exFAT is the usual choice: both macOS and Windows read and write it, and it handles large files. Its trade-offs are no journaling (an unsafe unplug is more likely to cause errors), no Mac-specific features like snapshots or permissions, and less tolerance for heavy use. Use it for drives that move between computers. For a drive that stays with your Mac, APFS is more reliable.

Short answer: exFAT — both macOS and Windows read and write it and it supports big files. It has no journaling or Mac permissions, so prefer APFS for Mac-only drives.
