Re: WD My Passport/My Book w/High Sierra In reply to jhersco • 11 months ago Thanks for the link to the article. WD External hard drive mounts on you macOS High Sierra when it is connected to Mac. Mounting makes the drive available for use and is visible in Finder and Disk Utility. In case the drive is corrupt, the data structure information is damaged or lost, which makes hard drive unmountable on macOS.

(Apple File System.) [UPDATE: ] Thanks to sharp-eyed Rocket Yard commenter Chris pointing us to an Apple support document, we now have a bit more information on,, and how it all works on Macs and on volumes that are formatted with the legacy HFS+ file system. [NOTE: At the request of several readers, we’ve added some “translations” to the Apple document listed below to make it more understandable.] Chris pointed us to this Apple tech document, titled. Probably the most important information from Apple is this quote: Apple File System (APFS) is the default file system in macOS High Sierra for Mac computers with all-flash storage. APFS features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals. When you install macOS High Sierra on the built-in solid-state drive (SSD) of a Mac, that drive is automatically converted to APFS.

Fusion Drives and hard disk drives (HDDs) aren’t converted. You can’t opt out of the transition to APFS. (Rocket Yard emphasis) So basically, if you install APFS on any Mac that uses a solid-state drive as a built-in boot drive, it will automatically convert to APFS and you will not have a choice. Those Macs that use Fusion Drives (like the iMac, for example) or good old hard disk drives will not be converted, period.

[UPDATE 09/25: Apple software engineering chief Craig Federighi has confirmed in a later update.] Here is the rest of the technical note verbatim, with our translation of Apple’s writing in italics. APFS compatibility Devices formatted as Mac OS Extended (HFS+) can be read from and written to by devices formatted as APFS. Translation: You can read and write to disk drives that were formatted as HFS+ from a Mac with a boot drive formatted as APFS.

Devices formatted as APFS can be read from and written to by: • Other devices formatted as APFS • Devices formatted as Mac OS Extended, if using macOS High Sierra 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. Translation: Drives of any type (USB flash drives, SSDs, HDDs) formatted as APFS can be be read from and written to from a Mac using High Sierra, even if it is not formatted as APFS. APFS and Time Machine • You don’t need to change any Time Machine settings to back up APFS-formatted disks. • Any Time Machine share points must be shared over SMB instead of AFP. Translation: You should be able to connect your Time Machine backup drive to your APFS-formatted Mac and things should run as expected. Vidbox video conversion for mac. The Backup Drive can be formatted as APFS or HFS+.

If you share your Time Machine drive over a network, it will need to be shared over SMB rather than AFP (Apple Filing Protocol). Apple has been moving away from AFP for the past few iterations of macOS. For more tricks and guides, including coverage of the, check out the page!

Wrong, you cannot reverse formatting and have never had that ability on any formatting type used on any OS or file storage drive, Mac or X86 or Linux etc. If you want to change you must offload your files and reformat. However the offload must be done on a Mac that can read APFS.

If you expected this feature you cannot have you should not have formatted a storage drive to use in a device that reads basically a windows based drive formatting type which is universally recognized i.e. Fat 32 for all USB flash drives.
