Apfs Or Mac Extended

Personally, if just data backup I would partition GUID and format as. MacOS extended, journaled (HFS+). In the even of some disaster, it. Mac os x 10 mavericks. Would be readable by any Mac that would be hardware compatible. With what ever drive type you are using. If it is formatted APFS, it will. Only be readable by a Mac running High Sierra or Mojave. One of the notable features of macOS High Sierra is the introduction of the APFS file system. APFS is a modern file system that replaces the extraordinarily aged HFS+, introduced in 1998.

In my MacBook Pro mid-2010 running High Sierra 10.13.6, I'm upgrading the drive to a 1 GB SSD (SanDisk 3D SSD). I replaced the drive, booted with another external backup drive, formatted the new internal SSD to APFS, and then used Disk Utility to restore the old drive to the new.


This process converted the SSD to regular Mac OS Extended (Journaled) formatting. When I select either the drive or the volume and go to Edit > Convert to APFS, it is greyed out. This happens whether I boot from the internal SSD or the old drive externally (both High Sierra).


How can I convert the SSD to APFS?

These instructions apply only to Mac computers with an Intel processor.
Erasing your Mac permanently deletes all of its files, so make sure that you make a backup of any files that you want to keep. If you're attempting to restore your Mac to factory settings, first learn what to do before you sell, give away, or trade in your Mac.

Start up from macOS Recovery

Turn on your Mac, then immediately press and hold these two keys until you see an Apple logo or other image: Command (⌘) and R. You may then be asked to select a user you know the password for. Select the user, then click Next and enter their administrator password.

Use Disk Utility to erase your disk

  1. From the utilities window in macOS Recovery, select Disk Utility and click Continue.
  2. Select Macintosh HD in the sidebar of Disk Utility. Don't see Macintosh HD?
  3. Click the Erase button in the toolbar, then enter the requested details:
    • Name: Continue to use Macintosh HD as the name, or enter a different name.
    • Format: Continue to use APFS or Mac OS Extended (Journaled), as recommended by Disk Utility.
  4. Click Erase Volume Group. If you don't see this button, click Erase instead.
  5. If Find My is turned on for this Mac, you may be asked to enter your Apple ID to authorize the erase. Forgot your Apple ID?
  6. After the erase is done, select any other internal volumes that may be listed in the sidebar, then click the delete volume (–) button in the toolbar to delete each volume.
    You don't need to delete the Macintosh HD volume you just erased, or any external volumes or disk images.
  7. Quit Disk Utility to return to the utilities window.
  8. If you want to start up again from the disk you erased, you should now reinstall macOS on that disk.

If you don't see Macintosh HD in Disk Utility

Your built-in startup disk should be the first item listed in the Disk Utility sidebar. It's named Macintosh HD, unless you changed its name. If you don't see it there, choose Apple menu  > Shut Down, then unplug all nonessential devices from your Mac and try again.
