For the best file integrity, though, I’d probably recommend doing this from Recovery Mode. You will notice that your Mac becomes unresponsive for a time, as it verifies the filesystem, checks everything out, and then carries out the resize operation.

Yes, You Can Resize Your APFS Container on a Live Filesystemīefore you ask, yes, I’ve verified this process works even when you’re booted into High Sierra on that APFS volume. If you still find that the drive is failed to get mount on Mac and requires recovery then, use Bitwar Data Recovery Software for Mac to recover all your data.

In this case, diskutil automatically claims all available free space on the physical storage device, but you can also replace 0 with a size value. Next, resize your APFS container: diskutil apfs resizeContainer disk0s2 0 sudo diskutil eraseVolume "Free Space" %noformat% /dev/disk0s3 This command will do the trick, assuming your volume is named disk0s3. First, though, you have to delete the JHFS+ or other partition and set it as free space on your hard drive. If you decide you want to reclaim that space into your APFS container, you can do that using diskutil as well. Shrinking Your APFS Partition to Reclaim Space

The diskutil command automatically locates the physical store for my APFS container, and resizes things accordingly.

Note that in my case, I could replace disk0s2 with disk1 for either command, since my APFS container is located at disk1. I could also create multiple partitions, using a command like this: sudo diskutil apfs resizeContainer disk0s2 750g jhfs+ Media 200g FAT32 Windows 50g The output of the command will look something like this: Resize you APFS container from Terminal I could have also issued the command like this, and diskutil would automatically determine the size for my new partition: sudo diskutil apfs resizeContainer disk0s2 750g jhfs+ Media 0b We need to use sudo here, to take administrative privileges over the Terminal session. That command would resize the APFS container from 1TB to 750GB, also creating a 250GB journaled HFS+ partition with the freed space. To shrink my 1TB APFS container to 750GB, I’d issue the following command in Terminal: sudo diskutil apfs resizeContainer disk0s2 750g jhfs+ Extra 250g

You use the same command for both processes, but you might be likely to want to reduce the size of your APFS partition first, perhaps to install another operating system on your Mac. Let’s talk about shrinking the APFS partition, or container, first. Locating your APFS container prior to resizing it Resizd Your APFS Container (the Hard Way) Note that my APFS container is named /dev/disk1, and resides at /dev/disk0s2. Once there, issue this command to find out where your APFS container lives: diskutil list Boot into Mac Recovery by keeping Option/Alt key pressed at boot.

The most easiest method you should try first is to use the fsck command-line tool from Mac OS X recovery to check and repair the consistency of the corrupted file system. The volume Macintosh HD was formatted by hfs_convert (748.21.6) and last modified by apfs_kext (945.250.134).To do this, you’ll need to open Terminal from Applications -> Utilities. Method 1 : Using inbuilt fsck 'file system check' utility to fix the node structure. Performing fsck_apfs -n -l -x /dev/rdisk1s1Ĭhecking the space manager free queue trees.

NOTE: First Aid will temporarily lock the startup volume. Raw First Aid output follows: Running First Aid on “Macintosh HD” (disk1s1) The only message I can diagnose with some certainty is the fourth one, according to this Apple Developer post, that says that some Time Machine snapshots were corrupted when Apple switched from the old file system to the new APFS. The volume /dev/rdisk1s1 could not be verified completely. error: Cross Check : FSroot tree references extent (#) which is not present in the ExtentRef tree Here are the five types of messages output by Disk Utility's First aid after stating "Checking snapshot 1 of 14" error: Cross Check : ExtentRef physical extent (#) has kind APFS_KIND_UPDATE but was not referenced previously Posts online mention different combinations of them, but none with all 5 and just the five. Can someone provide documentation or their own knowledge to interpret the below messages? I've researched this diligently but no post has the same combination of messages that I have.
