disk utility repair disk permissions mac os 10.12

Your Mac should be able to boot despite the MBR.This is the most user friendly way to view or adjust file permissions in Mac OS X, it works with anything found in the Finder file system, be it a file, binary, application, or a folder. Remove and restore the 2nd partition: gpt remove -i 2 disk0 Get some details: diskutil list #below I assume the disk identifier of the internal disk is disk0

Open in the menubar > Utilities > Terminal.

To get your APFS partition back remove partition disk0s2 and restore it with the proper type: In no case try to repair anything with diskutil! Any disk or partition verification executed with diskutil may yield some bogus result. Your boot system (in Internet Recovery Mode) seems pretty old. The default pMBR was replaced with an old-style MBR, probably by the Linux installation! Would it be possible (and how) to recover the data of the deleted partition (s2) if I reinstalled macOS on an existing unused partition (the Linux partition disk0s4)? The new disk utility does not recognize the disk0s2 partition at all, and diskutil list included the size of the main osx partition in GUID_partition_scheme part of the disk.

I created a MacOS High Sierra Installation disk, and rebooted to it. My data is not backed up and I would really love to recover it. My computer's model: MacBook Pro late 2013. What's the uuid of the new APFS format? I cannot seem to find it anywhere in the web, and my computer isn't detecting the type of the main macOS partition. I cannot boot into macOS, my computer is in internet recovery environment. When I tried correcting the GUID error as shown in the answer, after reaching the step in which the following command: gpt add -i 2 -b 409640 -s 372637568 -t APFS /disk0 had to be entered, it returned an error: usage: gpt add device.

I have encountered a nearly identical issue to the one in this question (and this too: Data Not Backed Up, Partition Type: FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF), but my hard drive's main partition is formatted in APFS.
