Since all the Mac systems have a different environment altogether, they are not compatible with all the existing file formats.

Also, multiple email clients extend their support to MBOX files, including Thunderbird, Apple Mail, Opera Mail, Spicebird, Entourage, Sylpheed, Eudora, Sea Monkey, etc. It is not a convenient way to store a series of emails holding relevant information, but still, users decide to use it. All the emails are saved in a back-to-back format which can be differentiated only by the ‘From’ header. MBOX is a simple format that stores all the messages of the mailbox in a single text file. You can also transfer the files from Apple Mail to PST, which is another suitable format to store the information.

But to get out of this problem, there are a few approaches that will help you to open an MBOX file in Apple systems as well. If you are a Mac system user, it might be a bit tricky to read them directly due to their formatting. These MBOX files have a simple format and can be opened on Windows as well as Apple environments. Users often use them to store old emails, which continue to hold relevant information that can be used in the future. MBOX is the most widely compatible format, supported by several email applications.
