One last thing to mention about the Mac OS Extended format is that it isn’t compatible with Windows, so if you want to use a given external drive with both Mac and Windows computers, we do not recommend this format. An HDD can still be formatted to APFS, but it’s recommended to use the Mac OS Extended format for mechanical hard drives (especially if you want to connect those drives to macs with older OS X versions). This is why it’s strongly recommended to format drives you intend to use with older macOS releases to Mac OS Extended (Journaled).Īlso, note that Mac OS Extended is optimized for mechanical hard drives (HDDs) whereas APFS is specifically created to work well with Solid State Drives (SSDs). Therefore, if, for example, you have an external drive formatted with APFS and a Mac running on macOS El Capitan, your Mac wouldn’t be able to access and read the data stored on the APFS-formatted drive. You see, one of the few problems with the APFS format is that it’s not compatible with macOS releases older than macOS High Sierra. The main reason to still use Mac OS Extended (Journaled) is reverse compatibility.

However, Mac OS Extended (also known as HFS Plus or HFS+) is still being used and, though it has a lot of disadvantages compared to APFS, there are several reasons why you may want to format a Mac hard drive (external or internal) to this format. Currently, the APFS file system is the default one in newer Mac models. For discussion of Mac OS X, journaling, or other related topics, visit the TMO forums.Since the introduction of the newer, more advanced, and better optimized APFS file system that came with macOS 10.13 High Sierra, the Mac OS Extended (Journaled) format started to get pushed to the sidelines.

The Mac OS X 10.2.2 update is available via the Software Update pane in the System Preferences.
More information on journaling in Mac OS X can be found in an Apple technology PDF. It should also be noted that journaling can exact a toll in the form of CPU usage. To disable the journal, type "sudo diskutil disableJournal /" (also without the quotes). If, despite the warning above, you wish to turn on journaling, open a Terminal window and type "sudo diskutil enableJournal /" (without the quotes).

You can also find out more about the CLI in Mac OS X Command Line: 101, our series by Richard Burton. If you would like to learn more about journaling and the command line, visit our Hardcore X! forum, and ask questions of the command line fiends that hang out there. WARNING! IF YOU DONiT KNOW WHAT YOU ARE DOING WITH THE MAC OS X COMMAND LINE, WE DO NOT RECOMMEND THAT YOU TURN ON JOURNALING USING THIS METHOD!!!
In desktop version of Mac OS X 10.2.2, however, you must use the command line (CLI). To enable journaling on Mac OS X Server, simply open up the Disk Utility application, select a volume, and click "Make journaled" on the Information pane. While Apple indicates that journaling is only available in Mac OS X Server 10.2.2, it is also present in the client release of the OS. This is essential for many server environments, where downtime can result in serious losses. As a result, downtime is greatly reduced and the effective stability of the system is increased. Instead, the system will replay the recent entries in the journal to correct any problems that may exist. This eliminates the need for a file system check during startup. In the event of a failure, your Mac can use this file to restore the system to a working state. It also helps to maximize the uptime of servers and server-attached storage devices by dramatically expediting repairs to the affected volumes when the system restarts.Įssentially, journaling tracks all modifications and operations on the file system and keeps a log of these actions in a journal file. Journaling protects the integrity of the file system on Xserve and other Mac OS X Server-based systems in the event of an unplanned shutdown or power failure. Mac OS X Server version 10.2.2 provides a robust new journaling feature for the Mac OS Extended (HFS+) file system that enhances server availability and fault resilience. Among other things, the update brings a journaling file system to the Mac. S we reported Monday, Apple released an update to Mac OS X to version 10.2.2.
