#MACOS YEARS USED RUNONLY AVOID FOR MAC OS#However, the file system in use before APFS, Mac OS Extended, isn’t as efficient when working with SSDs. An SSD also has no moving parts, so the likelihood of mechanical failure is extremely low. (In fact, APFS is the file system used by iOS devices, Apple Watches, and Apple TVs-all of which store data in solid-state memory.) An SSD provides much faster performance because it doesn’t suffer from the lag between macOS asking for data and a mechanical disk’s armature skipping to the correct positions on the platters to read it. Although mechanical hard disk drives are still widely used and offer the best price per gigabyte, solid-state storage media is the future. Let’s start with why Apple made the switch from Mac OS Extended to APFS in the first place. 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. #MACOS YEARS USED RUNONLY AVOID FOR 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. #MACOS YEARS USED RUNONLY AVOID FOR 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. ![]() #1620: OS updates, AssistiveTouch for iOS shortcut palette, Photos album sharing bug.#1621: Apple Q3 2022 financials, Slack's new free plan restrictions, which OS features do you use?.#1622: OS feature survey results, Continuity Camera webcam preview, OWC miniStack STX. #MACOS YEARS USED RUNONLY AVOID FOR HOW TO#
