I can’t see a trivial way to allow this to propagate backwards, even if Apple were in the habit of releasing upgrades for older macOS releases except for security reasons or Safari updates.Ī third-party might be able to use the APFS spec to allow mounting such volumes, but there seems to be little market for what would be an expensive product to develop and support only for an ever-smaller number of users of older macOS flavors who also had upgraded boot or external drives in High Sierra or later releases to use APFS.Īpple says encryption is built into APFS. APFS is a fundamental reworking of the filesystem, which requires extensive changes to the OS. My definitive answer is also no (though I don’t know Apple’s mind). One reader asked if Apple might release a compatibility upgrade for pre-Sierra OS X and macOS releases to allow them to mount APFS externally. We tested with a USB-connected SSD drive, and we can read and write to an APFS partition. Says in its APFS FAQ, “For example, a USB storage device formatted as APFS can be read by a Mac using High Sierra, but not by a Mac using Sierra or earlier,” this seems incorrect, as we’d heard from other Mac experts that Sierra could. Only Sierra, which can read and write APFS volumes. (That’s when you select a volume, right-click, and choose Encrypt “Drive Name.”) Can I mount an APFS volume on a Mac running an older version of macOS than High Sierra? No! Apparently, an unexpected behavior in this first release is that using the Finder-based option to encrypt a mounted physical drive converts HFS+ drives to APFS without warning. Should I turn on encryption on an external HFS+ drive in High Sierra? But I can’t imagine that HFS+ will be unmountable in macOS anytime in the next three years, and it will very likely remain possible for years after that-although Apple could only support read-only HFS+ mounting at that point. It will likely provide more and more reasons in future releases for external drives to move to APFS, like requiring APFS drives for Time Machine. It would be foolhardy and it’s unnecessary. Not for many years, because of the tens of millions of systems out there. (APFS drives apparently can’t be shared over the now-outdated Apple Filing Protocol.) Use Dropbox, SFTP, SMB, email, or any other networked file transmission technology to mount a remote volume, sync with a directory, or send a file or files.Turn filesharing on for your High Sierra Mac, and mount it as a volume on the older Mac.Eject that drive and move it to the other Mac. Attach an HFS+ (or other supported format) external drive to your Mac, and copy files to that drive.How do I move data from an APFS volume to a non-APFS volume or an older Mac? I would advise people who rely on clones as one leg of their backup process-something I strongly recommend-delaying High Sierra until both major clone-software companies express satisfaction with the state of documentation and stability on their blogs. (See below on converting external drives.) It’s not mandatory, but it’s a good idea. This command completely erases the USB, then creates native installer media from the Install macOS Beta Application.You should also upgrade your clone target to APFS for reasons of like-to-like compatibility, and if you want to have a bootable High Sierra volume.
