Solution  MBOX File

Mozilla Thunderbird

Apple Mail

Apple Mail stores messages inside .mbox bundle folders on macOS and the mailbox data is typically found under ~/Library/Mail/V[version]/. Exporting a mailbox from Apple Mail creates an .mbox folder containing the actual mbox file.

Gmail/Google Takeout
