Problem booting the Mac OS Sierra 10.12.6

#1 Post by whitewolf1608 »

Hello, I am very warmly I have installed the OS Mac OS

Sierra 10.12.6 on the second SSD.

I can not boot this system due to a corrupt HFS + file system.

When trying to boot from this SSD on which is macOS Sierra 10.12.6

or when I try to start booting from PenDrive I get a message

Operation System Not Found

All details on screenshots of the G parted tool are included.

Damaged HFS + file system I also have on my PenDrive.

In both cases the G parted tool communicates with me

Growing message is not available for this file system

The G parted tool repairs the HFS + file system to the final stage.

Unfortunately, G Parted can not cope with fixing the HFS + file system

to end.

Ladies and Gentlemen, I am very kindly asking for your support in solving

my problem.

Can I use the TestDisk tool to repair the file system?

HFS + on my SSD drive - where Sierra is installed

10.12.6 as well as HFS + on bootable PenDrive from the macOS Sierra installation

10.12.6?

Please kindly reply as quickly as possible
