Sometimes OS X doesn’t want to let you eject a volume or an external drive. Sometimes this is because a program is using a file on the volume in question, but other times the volume just seems to be stuck! Fortunately, there’s an easy solution! We’ll show you two ways to force your Mac to let go!

Method 1

  • We’ll show you two ways to force your Mac to let go! Method 1 The easiest and safest way to force a volume to eject is to open a new Finder window, locate the drive or volume in the left-hand column, right-click or option-click the volume, and select Eject “ Volume Name” in the drop down menu.

How to force mount a drive mac

The easiest and safest way to force a volume to eject is to open a new Finder window, locate the drive or volume in the left-hand column, right-click or option-click the volume, and select Eject “[Volume Name]” in the drop down menu. Apple cordless keyboard.

You may see a message like the one above, telling you that there may be a program using that volume. If you’re sure that’s not the case, then click “Force Eject…”, and Voila! That’s all there is to it!

Method 2

For those of you that prefer using Terminal, or would rather eject the drive with a single command, simply open Terminal, and type the following:

diskutil unmountDisk force /Volumes/DISK_NAME

Just replace DISK_NAME with the name of the volume you want to eject, press enter, and you’re done!

I’ve found that the first method is much more successful – I’ve had the disk fail to unmount more than once using the Terminal command.

Note: Make sure you have closed all applications that may be using the volume you want to eject, and that the volume is not in use. Otherwise, you risk facing data corruption or even data loss! And, as always, use Terminal commands at your own risk!

Great, Great, Great.
I am creating a lot of disk images at the moment for the distribution of a product and obviously I have to test those images. After mounting about 10 the Finder stops doing it's work as described in the hint. This problem exists even in 10.3.5 and I am very happy now, cause rebooting, the only solution I had figured out so far, really interrupts my work big time.
Thanks for the tip.

Rehab is for quitters!

I have an image that is password protected, and it still doesn't mount with this hint. Here's the output from terminal. Since the GUI password box came up on the display, I suspect that whatever OSX bug the command line evades is non-evaded when the PW function is called. Another encrypted image that mounts ok in the standard way (double-click) mounts fine using hdiutil. Haven't tried rebooting to see if that lets me mount the first image.

It just so happens that we already built an AppleScript solution using this method; I'll paste it below for those who are Terminally challenged. As for the issue with password protected disks, this script will indeed trigger a GUI window asking for any such passwords not already stored in Keychain. I have yet to find an instance where presentation of the password box triggered the failure we're looking to overcome in this hing, but the -stdinpass switch would likely resolve it (see the man page), and could be added to this script. Sorry about the code wraps, Rob, I tried to install AS returns, but they wouldn't deal with the line wraps any better because of the parentheticals.

Man, it is amazing how fast folks around here report bugs. Sorry for the oversights; the script was originally written for single DMGs, and I added multiples without really testing it or thinking it through; also we rarely use a special character in a file path because we're so used to working on the web. All bugs should be resolved, except those idiosyncracies that exist with name problems in hdiutil (such as 'image already specified' errors).

Now, if you could add an 'on open' handler that handled drag-and-drop, you'd be all set! Just drag your dmg files onto the script and they would mount. No file dialog to get in the way. :-)

AppleScript to Force-mount unmountable disk images

Hi there..
Well, I tried both versions of your script on several disk images (including one that I KNOW mounts fine by itself), and most of them were grayed out in my file dialog. My first thought was that perhaps they were corrupted, but at least one of them mounts fine on its own, and it was not accessible either.
I very much appreciate your scripting skills, but do you have any idea why I might be having such problems? Any suggestions from anyone else out there? I would really appreciate the help!
Thanks in advance,
mlaurenc

AppleScript to Force-mount unmountable disk images

I may just be a big newbie, (and I undoubtably am), but when running this script the only items I could select when it asked me which DMG I wanted to mount were file folders and no DMG files. Even with a foler selected, 'Choose' never highlit. Am I doing something wrong?
Also, is there an applescript super newbie thread I should be hitting up before getting to knee deep in this?
by the way, rebooting still didn't allow me to mount the DMGs. I'm running 10.3.7.
Thanks for any/all help guys!

While this is a nice workaround - I really wish the problem would be solved instead. Very annoying. On my machine - happens everyday after about my tenth disk mount. The image actually appears to get mounted and appears in /Volumes but it shows up no where else and is impossible to access.

I must say, it doesn't happen much with me. https://free-eyes.mystrikingly.com/blog/instabro-5-2-3-browser-for-instagram-password. But if it shows up in /Volumes, you should be able to refresh the finder by doing 'disktool -r'. I am writing a script that triggers mounting of dmg and the 'disktool -r' seems to solve some of my problem.
Good luck

I tried this Hint for the first time today, but I didn't appear to have the relevant utility. Typing in hd and tab brought up
hdiutil
which is not the command quoted in the actual command string in the Hint.
Anyway, I tried hdiutil, and it tried to attach the dmg, but failed with the same problem: no mountable file systems. <sigh>
Back to restarting..

Yeah, 'hdituil' is a typo.
