I'm automating my Mac installation using puppet. As a part of it I need to install several programs that come in a .dmg format.

I use the following to mount them:

sudo /usr/bin/hdiutil mount -plist -nobrowse -readonly -quiet -mountrandom /tmp Program.dmg

The problem is that some .dmg files come with a license attached, and so script is stuck accepting the license. (There is no stdin/out when running with puppet, so I can't manually approve it to continue.)

Is there a way to pre-approve or force-approve the license?

    Do "yes | hdiutil attach disk.dmg > /dev/null" - that'll type a 'Y' for you. – mauvedeity Oct 8 '11 at 11:35

If you have a GUI and are able to perform two command-line calls in parallel, you can use

/System/Library/CoreServices/DiskImageMounter.app/Contents/MacOS/DiskImageMounter /path/to/file.dmg

and

osascript accept.scpt

the latter of which executes the following AppleScript:

tell application "System Events"
    delay 5 # wait 5 seconds -- I tested it using two terminal tabs and needed the time
    key code 48 # press tab 4 times in the license window
    key code 48
    key code 48
    key code 48
    keystroke " " # press space to click "accept"
end tell

In bash, I'm able to write

/System/Library/CoreServices/DiskImageMounter.app/Contents/MacOS/DiskImageMounter file.dmg & osascript accept.scpt
  • I forgot to mention that I don't use puppet. This answer might therefore be terribly useless, but since it's been a few days, I posted anyway. – Daniel Beck Dec 25 '10 at 21:14
  • hmm I get an error when trying to run osascript accept.scpt ➜ dotfiles git:(master) ✗ osascript accept.scpt osascript: accept.scpt: No such file or directory – grant May 26 '15 at 19:13
  • @grant You have to create the file with the specified content first. – Daniel Beck May 26 '15 at 19:33

This worked for me when I encountered a .dmg that contained a EULA which I wanted to install it via the command line with no user interaction...

/usr/bin/hdiutil convert -quiet foo.dmg -format UDTO -o bar
/usr/bin/hdiutil attach -quiet -nobrowse -noverify -noautoopen -mountpoint right_here bar.cdr

(note: I am reasonably sure not all of the above options are needed to bypass the EULA, such as -nobrowse, -noverify, -noautoopen, -mountpoint. However, I used them and I didn't test without them so I didn't want to claim something that I hadn't tested.)

What I ended up with was a directory with

bar.cdr
foo.dmg
right_here/

where right_here/ contained the contents of the foo.dmg without being prompted for the EULA.

Be sure to detach when you are done!

/usr/bin/hdiutil detach right_here/

    Thanks -- this worked well with a multi-page agreement, where a repeated 'y' didn't work. – Lars Rohrbach Sep 17 '12 at 22:14
  • Worked for me too. Although I just needed the first line to convert it to a cdr file, then I can just attach it without all those argument and it works. – Maxime Viargues Nov 20 '17 at 21:17

If it just needs "Y" typed in, then pipe the yes command into the hdiutil command:

yes | /bin/hdiutil [...]

That will emulate pressing 'y' and return at the command line.

To type something else, just put it on the command line as a parameter:

yes accept | ...

That'll enter 'accept' into the script.

Note that if the script asks for input multiple times, the yes command will put multiple entries in. You may see output like 'broken pipe' - this just means that the command you piped into quit while 'yes' was still sending input.

  • I've never tried this, so I didn't know about the stout redirect. Thanks for the +50! – mauvedeity Oct 10 '11 at 22:26

I recently came across a DMG that had a EULA and it was really irritating me since I couldn't script around it. I figured out if I converted the DMG to a CDR it bypassed the EULA on mounting the CDR.

Here's what I did:

hdiutil convert foo.dmg -format UDTO -o bar.cdr
hdiutil attach bar.cdr
rm foo.dmg <--optional

Hope this helps.

  • This helped me a ton! The yes | hdiutil... solutions would hang for me when called from a python script for some crazy reason. – Nathan Apr 16 '15 at 3:37

If you have a multi-paged EULA that you need to accept, you can get to the accept part by putting a q before the rest of your accept command (since all you need is an accepted quit command in less, you could also use ZZ or Q).

For example, if the EULA requires you to type a y to accept you'd run:

yes qy | hdiutil attach ...

Shouldn't you be using puppet's own tools to install packages? I'm a radmind admin myself and I'm not familiar with puppet, but a check on their wiki reveals that there is a tool called pkgdmg that might do the equivalent of what you're trying to accomplish.

    it doesn't handle apps that require accepting license. – Vitaly Kushner Feb 3 '11 at 19:39
  • Indeed; I was under the impression that you would be creating your own packages with no need for a license acceptance. Such is the mindset of a Radmind admin, I suppose. – NReilingh Feb 3 '11 at 22:51
