Easily Mount an ISO in Mac OS X

Apr 22, 2008 - 87 Comments

ISO If you’re wondering how to mount an ISO image in Mac OS X, it is very easy. For most ISO images you can mount them simply by double-clicking the ISO image file, and it will go through the auto-mounter app within Mac OS X putting it on your desktop.

If for whatever reason that doesn’t work there are other methods to mount ISO’s within Mac OS X, and we’ll cover ways to do this with the built-in Disk Utility and a more advanced option of using the command line.

Mount ISO on Mac with Disk Utility

You can mount ISO images in Mac OS X by using Disk Utility, located in the /Applications/Utilities/ directory. After you have launched Disk Utility, navigate from the Disk Utility menu down to “Open Image File” and select your ISO file. The ISO should now appear mounted on the Mac OS desktop. Yes, this works for other disk image files too (dmg, img, etc).

mount iso mac

You can then burn the ISO if needed, or just use it as a mounted disc image as needed. Ejecting the ISO is done by selecting the mounted image and dragging it to the trash, or by hitting Command + E keys with the ISO selected in the Finder of Mac OS X.

Mount ISO with Mac OS X command line

Another option is to mount an ISO using the command line on Mac. In the Terminal type the following command:

hdiutil mount sample.iso

With sample.iso being the path to the image you want to mount. For example, ~/Downloads/sample.iso

After the checksum is completed, your ISO will appear mounted on your Mac OS X desktop – that’s it. You you can actually mount virtually any other disk image type with hdiutil as well, so give .dmg .img a try too.

    I have been on the mac since 1987. Disk Utility has been a great program almost like the Swiss Army knife of image files and hard disk on the Mac.

    But recently it seems to me that Disk Utility has been purposely crippled on my Mojave Mac.
    I can create a cdr image from a CD and it is not only unmountable by Finder but Disk Utility says it is unreadable when I try to open it!! This is nuts! Disk utility just created the image file and then tells me it cant read it! WTF!!

    I have made iso files from Burn shareware for the mac, still unreadable. I used this utility for years and now it will not mount from finder. Did they remove finder support for ISO files?

    I look on Windoze, and there is a plethora of choices for shareware and retail software to build, burn and manage iso files.

    And, all the instructions that come up for this issue are old, like before 2012 old.

    What gives? ANyone out there successfuly using iso files with his/her mac?

    I have an .nrg file on a removable disk which contains Mac native software. I believe the file is Nero, which is not Mac compatible. I found out that I needed to convert it to an .iso file.

Everything I read suggests that Macs can read ISO files with no problem but that is not my experience. Any ideas?

  24. JazzyJ says:

    The only program that can mount in the same ways a Daemon Tools etc on a Mac is Roxio Toast.

    If you mount Disk Images using the OSX disk utility you get a white drive icon. If you mount using Roxio Toast you get a silver CD icon.

    If you need to mount CD images for games etc then you have to use Roxio Toast for OSX.

    There is absolutely no other alternative that exists by any company or program for OSX and never has been.

    Google is full of hits for ‘Alternative to Daemon Tools for OSX’ and thre is nothing except for Toast.

    Hi, I’m also quite new with Mac, and can’t solve a problem: I would like to create .iso or .dmg images from audio CD, which I cannot using the disk utility (somehow it doesn’t recognize). Then, if I convert it using my Windows into .iso, I cannot mount it — the reason is the same. I tried typing in the terminal as well, but the message is the same: Mount failed – not recognized. (No double click, no disk utility.) Any suggestions? It would be so important… Thanks.

  36. rippsss says:

    i am trying to mount a series of .iso images that work fine on my XP machine. when i try to mount them through the terminal i get the following error:
    hdiutil: mount failed – not recognized
    i receive similar errrors when attempting to mount the image by double-clicking the icon from the desktop and attempting to open the image in disk utility.

    any thoughts on what is going on here? the software on the disc is supposed to be Windows/Mac compatible and, as i mentioned, i have been running the program from images mounted on my XP machine for quite some time now.

  37. spamaoararoaa! says:

    type the following command: hdiutil mount sample.iso with sample.iso being the path to the image you want to mount. After the checksum is completet, your ISO will appear mounted on your Mac OS X desktop – that’s it. You you can actually mount virtually any other disk image type with hdiutil as well, so give .dmg .img a try too.

  38. Kerry says:

    Confused, it may just make you more confused, but if you open Teminal and enter man hdiutil you will get the manual page for hdiutil. It’s possible some of the optional tags for the command, like -verbose or -debug might give you a clue.

  39. Confused says:

    I successfully mounted the disk, but i still cannot open the application because it says there is no disk inserted. It is clearly mounted, though. Any suggestions?

  40. Newb says:

    Fantastic, worked like a charm, appreciate it.

  41. Michael says:

    @Newb , you can usually just mount an iso by double clicking on it which will mount it through Disk Utility. If you want to use the command line though just type

    hdiutil mount ~/Desktop/imagefile.iso

    ~ is your home directory, and /Desktop/ is the literal desktop. Alternatively, you can just type hdiutil mount and then drag the file itself into the terminal and the path to it will appear after ‘hdiutil mount’ which works well if your file is in some obscure location

    • uyen says:

      hi,
      all the files are unix executable files after I mount .iso file. How can i install .iso file on Mac? it’s a software.
      thank you.

  42. Newb says:

    Ok, so I hate to be a newb and post a newb question, I am a very new mac user (in fact got it yesterday), and thus far love it, however I used to mount dvd iso’s on my windows laptop and watch them using powerdvd (to save on the battery). What I am trying to figure out is the exact command string that needs to be entered in Terminal for an iso that is located on the desktop. I tried just opening terminal and entering the details as per the example at the top of the page but it could not find the file (i’m assuming that the example assumes that the iso is in a root directory). In windows it was pretty simple c:/folder/file.iso if anyone can point me in the right direction that would be great. Cheers

    Thanks again.

  45. klm says:

    (shucks – missed a backslash there…)

  46. klm says:

    @matt and lucky, mabye there are spaces in the name of your .iso? if so, you have to do something extra to make the shell delivering the name to the program as a single, unitary item – you need to quote or escape the name.

    for example, use quotes around the name:

    hdiutil mount “Final Fantasy XVLII – Yet More.iso”

    alternately, you can also use backslashes to “escape” the spaces:

    hdiutil mount Final\ Fantasy\ XCVI\ -\ The Epoch.iso

    avoiding this delicacy in expressing special characters is one way a gui can make things easier – but sometimes, at the loss of flexibility.

  47. chris says:

    matt, and lucky i think the problem is that your not actually mounting an iso. your most likely trying to mount an .rar, etc. so make sure you DL a program like UnRarX and extract the .rar file then mount the .iso file that pops up.

  48. Drago says:

    can one boot mac software .iso image dvd on a mac or does it have to be .toast image extension?

    I got the same thing, Matt. Any suggestions, anyone?

    any suggestions??

    @ Kesr: good point, but as unix commands are case sensitive, make sure to type “cd Desktop”

  56. tc says:

    Hi. I’m trying to mount a wii iso file and even though I follow the above instructions, it simply doesn’t work. It says the iso file cannot be mounted (or something to that effect). Any ideas? I can’t burn it if I cannot mount it properly.

    • Fishcake21 says:

      Wii isos uses a custom proprietary file system that Operating systems do not recognize.

      And if you burned the disc, it will show on windows as unrecognize format, but with OSX it will show as a blank disc when that is not true, and you have to do a raw data dump.

      Of course i don’t expect you to know about this… completely off related topic..

  57. Kesr says:

    If your iso is on the desktop, simply type ”Cd desktop” in terminal before typing ”hdiutil mount sample.iso”

    Okay, *sigh* I will explain…

    ISO.
    ISO is _not_ an IMG.
    got it?

    • BeforeA says:

      An ISO is an image, dimwit.

      • Stephen says:

        A JPEG is an image as well but you can’t double click to mount those in Mac OS X either.

        See what I did there?

        • James says:

          ISO and IMG are much the same thing; they’re both filesystems in a distributable/ loopback form- an ISO is usually an iso9660 image (Which is where we get the name from) though of course because OSX relies on magic numbers and not suffixes it could be anything:

          bash-3.2$ file centos-5.5.img
          centos-5.5.img: ISO 9660 CD-ROM filesystem data ‘CentOS_5.5_Final’ (bootable)

          Now; hdiutil is essentially a wrapper around the mount command to do the Mac specifics; you can see this with strings /usr/bin/hdiutil|less.

          I know it is tempting to jump on the perceived “I’m a Mac user, that must mean I can be a dick” bandwagon but seriously? Use your brain a little more.

    • Ange says:

      Didnt it say that it works with img files the article? -_- its a bit proof eh?

    • BEFOREZURADICK says:

      Yes, this works for other disk image files too (dmg, img, etc).

  63. paulc says:

    It worked.. but now what? the image is mounted but when i click on it it just does the same thing… which is nothing lol.. please help

  64. @ngel says:

    I tried it with an .img file and it doesn’t really work…

    • Flemming says:

      hdiutil mount filename.img
      worked just fine for me. I’m on Snow Leopard (10.6.5)

      My .img was a dvd-image and after mounting it played just fine in DVD Player

  65. uxp says:

    @ James: This is a whole lot easier than trying to use the GUI when you’re logged in remotely via SSH. :)

  66. James Nevara says:

    easy enough, is it really any harder than that in the desktop gui view?
