Nov 08, 2019 Drag the dmg file from your Finder window onto the Terminal window and let go. This will fill in the location of the dmg file into your Terminal window. MacOS Sierra (10.12) and earlier is not able to mount the new Apple File System (APFS). A.dmg file is kind of like an USB stick in a file and can be handled more or less the same way. To install from a.dmg file you usually do the following: double click the.dmg to make its content available (name will show up in the Finder sidebar), usually a window opens showing the content as well. Feb 19, 2008 Question: Q: dmg downloads won't mount. Trying to update some software and I'm finding that dmg files won't mount. The dmg files work on another computer running the same version of OSX. I don't get the standard warning telling me that I may be downloading an application. Force The same as -f; forces the revocation of write access when trying to downgrade a filesystem mount status from read-write to read-only. Noasync This filesystem should not force all I/O to be written asynchronously. Noauto This filesystem should be skipped when mount is run with the -a flag. Nodev Do not interpret character or block special. Jesus Vigo goes over the steps to create a bootable USB to install OS X 10.7-10.8 and OS X 10.5-10.6, as well as how to put multiple versions on the same USB.
Kenichi Watanabe, that is an ingenious use of the Disk Warrior preview, smart.
There is a command you can run in Terminal it is actually 'diskutil' another way to access the features of the Disk Utility.app
$ diskutil help - will list help for the command
$ diskutil mount - will list help about mount (because of missing args)
$ diskutil list - will list connected drives (whether mounted or not)
from that list select the identifier to mount eg…
$ diskutil mount disk0s1
$ diskutil mountDisk MyDriveName
I assume you know that the $ is not needed & can understand using the Terminal.
If disk utility the Application won't mount because of damage the terminal version may not either.
PS
'diskutil mountDisk BackupDrive' is handy when used in a shell script prior to making automated SuperDuper! clones. You can also eject them when done too.

Just tried this on my home machine running a webserver. Dragged an image to the Web folder and mounted it thru the Terminal over the internet just as you detailed.
(e.g. hdiutil mount 'http://www.mydomain.com/Image.dmg')
Very Cool

Wouldn't be very hard at all to make a Cocoa wrapper...I'll see if I get around to it today...Any ideas on how it should be designed (feature-wise and/or gui-wise)?
Select an URL in a Cocoa program. Go to the Services menu. Disk Copy. Mount Image. DC will launch and the disk image will be mounted remotely! That explains what that strange Service item was used for!
Since Services are only available in Cocoa apps, I think a general app that did this would still be quite useful. Drag-and-drop a URL onto the program, and that's basically it. Maybe when it's running there's a small 'well' onscreen where you can drag stuff, in addition to the usual drag to dock.
Maybe a list of recently visited .dmg files, too, to make going back easier.
Thoughts off the top of my head...
-rob.

The obvious question is, is it a good idea to mount a large update like this remotely and then run the updater from it or is that going to be worse/slower/use-more-bandwidth than just downloading the entire image and mounting it then?
It depends, really. It depends on how the programs you use on the files were written - if they keep files in memory or read them again or again. At the recent WWDC, Apple emphasized that developers should use the disk sparingly, as it could reside on a network with slow performance.
For most applications it probably doesn't matter. Its probably best to download the dmg if you are going to use most of its contents...I haven't done a lot of testing, so you may have to experiment some to find the optimal working pattern.

Terminal method works for me, but not the service
I just mounted a remote copy of the new QuickTime installer. Whee! I was able to examine the contents with Pacifist and SNAX, although examining them with the Terminal was much faster, including the VolumeCheck script. One use for this would be to quickly decide whether you wanted to download such a package at all (esp. if us are stuck with a dial-up connection). I was tempted to try running the installer, but I decided there was likely no faster road to spinning-beachball hell.
On a less successful note, when I try to mount a volume (even a local one) with the Disk Copy service, the classic version of Disk Copy is invoked, even though the correct application open it when it is double-clicked.

Couldn't get this to work for me. Running 10.1.5 on a Powerbook. Tried one of the examples at the Terminal command line and got:
hdid: unable to convert path to CFURL - error 0x000003E7 (999)
hdiutil: mount: mount failed (59136).
hdiutil: mount failed - unknown error (59136)
No idea what that all means.

hdiutil: mount: mount failed (59136).

Umm...never mind. I had a couple misplaced spaces in the imagename string.
Works fine now.
Works fine now.
Does hdiutil have a timeout? Is it trying to pull the update over and then mount it, or when I access something on the remote disk image does it access that remote server?
It worked fine with my iBook 500 (10.1.5, 320MB) on a LAN connected to the outside world via a T1.

It doesn't download the complete image. It access it in a random fashion, using resume/continue commands, i would guess. Which is why some servers will not be supported.
Yes, the content is only partially retrieved: here's a sample HTTP request made by hdid:
GET /diskImaget/encrypted.dmg HTTP/1.1.
Host: 192.168.7.12:80.
Range: bytes=0-511.
There is also a side note not yet mentioned: if you mount an encrypted disk image remotely, the encryption is deciphered only after the partial retrieval, that is the data is secured during transmission. (At least that is what it looks like, based on analyzing the HTTP requests sent. I wish someone could confirm this.)

i remember the Disk Utility in the services menu under 10.1.5 but it seems to be missing from the jaguar services menu. can anyone confirm this?
thx
ppmax

Not sure about Jaguar, but it sure ain't here under Panther.
comes up with the error 'does not appear to be a disk image: internal error'. Seems to be logical since Apple binhexed the the images. Is there an option in hdiutil which allows binhexing first before the image is remotely mounted?
I managed to mount a .bin image...Hmm...
Alright, I've spent a few hours (literally) hacking up a GUI for this little trick. Its written in AppleScript Studio, so Quick n' Dirty is the name of the game. Regardless, it works and is customizable. Check it out at Remote Image Mounter.
This could be really great for an IT department that wanted to make disk images available to its clients. There are dozens of handy uses for this!
I've administered Suns, and as a matter of fact we used NFS servers (Network File Systems) to remote mount users home directories. This way you could log in to any system in the company and see all your files.
We even remote mounted CDs, as several older Sun systems didn't come with CD-ROMs as standard.
Local UNIX accounts from what I've seen are a bit unusual in the business world.

Macs have been able to remotely mount volumes and CDs as well, but this is the first time we have seen remote mounting of disk _images_.
Is there a way to mount the images so they are writeable? I've tried a few different things (setting permissions on the image itself, converting the type of image to UDRW, etc.) but nothing seems to work. Mounting the image locally will allow me to write, mounting the same image remotely wont.
I'd like to have a few 100 MB images on my server and allow my family and friends to access the images to mimick iDisk functionality. I'm aware that there might be better ways to provide space, but this way I can limit their disk use to 100 MB (or whatever)
Any information would be greatly appreciated.

URLs which start with 'disk://' automatically spawn Disk Copy to mount them over the internet. For an example, go check out WHAMB:
http://www.whamb.com
The download section offers you the option of downloading the disk image containing the software or mounting it over the internet. It seems that you just have to make sure it's an actual .dmg file (not .sit or .gz or any other compression applied), get the web download address, and replace 'http' with 'disk'.
And all without the command-line.
Disk Copy doesn't seem to honor the Proxy settings in the Network System Preferences unfortunately, so this doesn't work for me behind our firewall, but it all should in theory.
