This is why itвЂ™s recommended to format drives you intend to use with older macOS releases to Mac OS Extended (Journaled). One of the main issues of APFS is that Macs running older versions of macOS arenвЂ™t able to access it.ДЇor example, if you have an external drive formatted with APFS, and connect it to a Mac running macOS El Capitan, your Mac wouldnвЂ™t be able to access and read the data stored on the drive. The main benefit of Mac OS Extended is reverse compatibility.

Thus, if you try to use an APFS-formatted drive to back up your Mac using Time Machine, macOS will ask you to format it to Mac OS Extended before you can proceed.ДЄlthough APFS is much faster and more reliable, there are still a few reasons that you may want to use Mac OS Extended.
