One of the recent changes Apple made to iOS and macOS is introducing a new file system called APFS which would be replacing HFS+, a file system that was previously used by both platforms. However it was recently discovered that Mac computers with Fusion Drives would not support APFS.
The good news is that if you do own a Mac with a Fusion Drive, you’ll be pleased to learn that support for APFS will be coming in a future update. This means that users won’t be missing out on the features and benefits of using APFS. This is according to an email sent by a MacRumors reader to Apple’s software engineering chief Craig Federighi, who responded by saying that support for APFS on Fusion Drives will arrive in a future update.
However Federighi did not mention when exactly support will be coming, which means that for all we know, it could take a while, but hopefully it won’t. It is rather strange considering that earlier previews of macOS High Sierra did include support for APFS on Fusion Drives, but for whatever reason Apple decided to remove it in later releases, and it did not make the final cut.
In any case we guess better late than never, and we’ll definitely be keeping our eyes peeled for when the update is released.
