![]() If you decide to format a drive in Disk Utility to set it to Mac OS Extended, you may notice that there are four different types available. You should consider Mac OS Extended if you're looking to use your drive for any of these purposes. ![]() Similarly, Time Machine and Fusion Drive only work with Mac OS Extended and not APFS (yet). This doesn't mean that you can't format an HDD to APFS-it's just that many of the speed and performance enhancements that APFS brings rely on using a high-speed SSD or portable flash memory drive. This is why it's recommended to format drives you intend to use with older macOS releases to Mac OS Extended (Journaled).Īnother benefit of using Mac OS Extended is that it's optimized for mechanical hard drives (HDDs), whereas APFS was specifically created to work well with Solid State Drives (SSDs). Thus, if you're using an older Mac, you'll need to either keep using Mac OS Extended or use an alternative such as ExFAT instead.įor example, if you have an external drive formatted with APFS and connect it to a Mac running macOS El Capitan, your Mac wouldn't be able to access and read the data stored on the drive. The biggest downside to using APFS is that Macs with older macOS versions (macOS 10.12.6 Sierra and older) can't read, write, or access drives that use it. This, alongside its speed and optimization improvements, makes APFS a great file system format. Similarly, improvements to metadata mean it's very quick to determine file details, such as how much space a folder is taking on your drive.ĪPFS is also more reliable, leading to less file corruption when compared to Mac OS Extended. It became the default format with 2017's macOS High Sierra and offers many benefits over Mac OS Extended, the previous default.ĪPFS is much faster at basically everything-data handling, copying, and pasting are quicker. Both bookstores and libraries have books on the shelves, but at the library you would look. Its how I formatted my HDDs, but what I am asking myself is if this is the best way to format an SSD. If you've recently bought a Mac or moved over from Windows, you may be wondering-what is the AFPS format? APFS, or Apple File System, is Apple's newer file system for solid-state drives and flash memory. Windows uses FAT or NTFS, OS X uses Mac OS Extended (Journaled). This article explains how to format USB drives for Macs and why it is necessary. On a Mac with multiple partitions, go to Disk Utility > choose partition > Partition > - > Apply > Partition > Done > partitioned drive > Erase. But what's the difference between both, and which one should you choose? Here, we'll discuss both file systems and offer a comparison to help you decide. Connect the USB drive, go to Disk Utility, select the drive, and go to Erase > Mac OS Extended (Journaled) > Erase > Done.
