Apple’s newest file system is the default for new installs and upgrades, unless otherwise specified by the user. The final code for Apple File System (APFS) was released to the public alongside macOS High Sierra in 2017.

Marking the switch to Intel-based processors, Apple introduced OS X, a redesigned operating system based on UNIX that was capable of running on the new hardware. Mac OS Extended ( HFS+) was introduced in 1998 for Mac OS 8.1, the previous iteration of the desktop operating system found on Apple’s computers which ran on IBM’s PowerPC processors. SEE: Data backup policy (Tech Pro Research) HFS+ In particular, we focus on performance, usability, and which special features (if there are any) will benefit users the most. We compare HFS+ and APFS to determine how the file systems stack up for end users. The new file system is called APFS, and it has modernized technologies that address the shortcomings of HFS+ and includes new features to provide better support for all Apple products.īut is the latest Apple file system really the greatest, or is the remedy a step backwards? WARNING:Formatting the drive will erase all data on the drive, so you should copy any data you want off the drive prior to formatting.Apple’s venerable yet flawed HFS+ file system has been criticized for years, and it finally received a replacement in 2017. If APFS is not available then the drive is in MBR and not GUID Partition Map. NOTE: Make sure that Scheme is set to GUID Partition Map and not Master Boot Record (MBR). Check step 2 to confirm Disk Utility is Showing All Devices NOTE: If you don’t see Scheme, then make sure that all devices are showing and the non-indented entry is selected. Select the non-indented entry, you will see Media in the nameĬlick the button labelled Erase in the menu which will bring up this window.Click View in the upper left and select Show All Devices.To open Disk Utility - Open Finder > Applications > Utilities > Disk Utility IMPORTANT: Reformatting the drive will erase all data on the drive, so you should copy any data you want off the drive prior to formatting.

If you need to go between macOS and Windows then format your drive ExFAT on macOS APFS does not natively work with Windows.APFS formatted external drives are not compatible with Time Machine on macOS versions High Sierra to Catalina. Time Machine requires the external drive to be formatted Mac OS Extended (Journaled) for these versions.APFS is only available when Scheme is set to ‘GUID Partition Map’, APFS will not be shown when Scheme is set to Master Boot Record – See Step 6. ![]()
