Dear LQ member
I am currently having problem mounting img file.Appreciate anyone to have a step by step I am trying to convert the IMG file to ISO for installation of the OS to Macbook. My Errors details as below:

macbook@macbook-MacBook ~/Desktop $ dmg2img /home/macbook/Desktop/MacOSXUpd10.5.5.dmg /home/macbook/Desktop/MacOSXUpd10.5.5.img

dmg2img v1.6.5 (c) vu1tur (to@vu1tur.eu.org)

/home/macbook/Desktop/MacOSXUpd10.5.5.dmg --> /home/macbook/Desktop/MacOSXUpd10.5.5.img


decompressing:

macbook-MacBook Desktop # sudo mount -t hfsplus -o loop MacOSXUpd10.5.5.img /media/image
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error

In some cases useful info is found in syslog - try
dmesg | tail or so.





Appreciate to all the help
Thank you

What happens if you remove the -t hfsplus?

Was there any valuable information in dmesg or syslog? (as suggested)

If this img file contains more than one partition, then it may be an image of the device (including multiple partitions and a partition table) rather than an image of just a partition (which is what's needed to mount via loop).

http://osxdaily.com/2011/12/17/mount...e-in-mac-os-x/ mount it and use it from macos?

Hi Grail
I got this error when mounting -t hfsplus as you advised.

macbook@macbook-MacBook ~ $ sudo mount -o loop MacOSXUpd10.5.5.img /media/image[sudo] password for macbook:
mount: MacOSXUpd10.5.5.img: failed to setup loop device: No such file or directory
macbook@macbook-MacBook ~ $

Thank you

Hi Jefro
Right now the macbook is install with Linux Mint 18.2. I have got rEFind install in the Macbook. When I slot in the original DVD that contain the OS in the Macbook CD/DVD Drive and reboot the system I am able to see the Mac OS in rEFind and when I select it,nothing go and it revert back to Linux Mint OS which is install in the system.

I have gone to Apple site and download mac OS 10.5.5 in DMG format and have converted into IMG. The file has been converted successfully. I am now stuck at mounting the IMG file into folder Media/IMAGE as advise by http://dailytechnologiesupdate.blogs...in-ubuntu.html, I have got the Media/Image folder created.

Thank you

Are you sure your kernel has loop enabled in it? And it is loaded?

Try:
If no output you may need to modprobe it and then try again.

yes, file would tell us the file type.
kpartx is useful for mounting disk images with multiple partitions. not sure if it is available for mac.

should this be moved to the other-*nix sub-forum.

Hi Grail
Please the output as below

macbook@macbook-MacBook ~ $ lsmod | grep loop
macbook@macbook-MacBook ~ $ lsmod | grep loop
macbook@macbook-MacBook ~ $

How do I check loop enabled and is loaded?

Thank you

Hi schneidz
Please see output as below

does kpartx work ?:

Hi Schneidz
Please find the output as below:

macbook@macbook-MacBook ~ $ kpartx -av MacOSXUpd10.5.5.img
/dev/mapper/control: open failed: Permission denied
Failure to communicate with kernel device-mapper driver.
Incompatible libdevmapper (unknown version) and kernel driver (unknown version).
device mapper prerequisites not met
macbook@macbook-MacBook ~ $

Thank you

Probably need to run kpartx as root, ie sudo.

Try running the modprobe first:
Assuming you now get output for the above you can try the mount again.

Although it may still error if a multi-partitioned image.
