APFS offers a few notable automatic benefits and some useful things you can do directly. But in the process of writing my just-released book Take Control of Your Digital Storage, I learned why Apple went to all the trouble.
#OPTIMIZE SSD FOR MAC OS X PRO#
High Sierra converted my 2016 MacBook Pro when I upgraded and, since nothing blew up, I filed APFS away as another technology shift that Apple managed efficiently. To find out, open Disk Utility, click your startup disk in the sidebar, and look under the disk name. You may not even have noticed that your Mac is now running APFS. There are any number of ways the switch to APFS could have gone wrong, but for most people the shift was seamless-if a bit more time consuming than most macOS upgrades. The file system is the bedrock-level technology that specifies where data is stored-not just in terms of how files and folders are represented in the operating system, but where individual bits are physically stored in the cells of an SSD chip or on the magnetic surfaces of the spinning platters in a mechanical hard disk drive.
#OPTIMIZE SSD FOR MAC OS X UPDATE#
Installing the update on a Mac with a solid-state drive (SSD)-but not a Fusion drive-automatically switched the underlying file system from Mac OS Extended (also known as HFS+) to APFS (Apple File System). When Apple released macOS 10.13 High Sierra in 2017, one of its most notable features was nearly invisible.
