![]() In either case, the external drive won’t be recognizable by the older operating system. The problem comes about should you ever connect the drive to a Mac running an earlier version of the Mac operating system, or if you boot your Mac to an earlier version of the OS. If these two conditions are met, and you select the option to encrypt the drive, by right-clicking the drive icon and selecting Encrypt from the popup menu, the drive will be converted to APFS format and then encrypted.Įven though the drive has been converted to APFS and encrypted, it will continue to work just fine with your Mac running macOS High Sierra. Must not have a Mac operating system installed on the drive.Under certain conditions, encrypting a drive will modify the format to APFS without the user being aware of the changes. Related: A Note On High Sierra Compatibility with Third Party SSDs (Encrypting an external drive can lead to the drive being converted to an APFS volume.) The same is true for APFS (Apple File System) formatted drives choosing the encryption option shouldn’t change the APFS format of the drive. ![]() If the drive was HFS+ (Hierarchical File System) before you chose to encrypt it, it should remain an HFS+ drive afterwards. MacOS High Sierra continues to support full disk encryption, but Mike Bombich, who created Carbon Copy Cloner, has verified a bug in High Sierra that will cause an external drive to have its format changed from HFS+ to APFS when the drive is encrypted in High Sierra.Įnabling encryption on a drive should not alter the underlying drive format. ![]() This is especially true for portable Mac users, who need to worry about their Macs being lost or stolen. Full disk encryption has been a boon for Mac users who worry about their personal data being easily accessible on their Macs or external drives. The tradition lives on with macOS High Sierra, so we’re gathering a list of what High Sierra broke and how to fix it (when you can).Įncrypting an entire drive to add a level of security has been an easy task in the Mac OS ever since FileVault 2 was released as part of OS X Lion. It seems with each new version of the Mac operating system, there are some features that just don’t seem to work the way they used to. High Sierra is so similar to Sierra in so many ways that it’s honestly pretty hard to tell them apart.It’s almost become a tradition one that we wish we didn’t have to put up with. Updates like Mountain Lion and El Capitan have drawn comparisons to Snow Leopard for focusing on refinement rather than features, but High Sierra is the closest thing we've gotten to a "no new features" update in years. But the UI doesn’t change, apps get only minor updates (when they get them at all), and multiple features continue to be more limited than their iOS counterparts. ![]() Changing filesystems, adding external graphics support, adding support for new image compression formats, and updating the graphics API to support VR are all important, and none of them are small tasks. That's not because there's nothing here but because most of Apple's development work this time around went into under-the-hood additions and updates to foundational technologies. If you've felt like the last few macOS releases have been a little light, High Sierra won't change your mind. ![]()
