Yes, Apple Mail can open MBOX files, but the process depends on how the mailbox is being accessed. If the MBOX file contains emails exported from another application, Apple Mail provides an import option under File Import Mailboxes. Select the option to import data from an MBOX format file, browse to its location and follow the prompts. Once the import finishes, the messages should appear in a separate mailbox under the import section.
If the intention is to move those emails into another format, such as PST, EML or MSG, Apple Mail alone may not meet that requirement. In that case, WholeClear MBOX Converter provides additional export options for Mac. I’d keep the original MBOX file unchanged until the imported messages and attachments have been checked.
