    For anyone struggling to use this on a Mac (until hopefully one day a MAC binary is made avalable), I found a way to run it without having to boot a virtual machine or go into bootcamp.

    Download PlayOnMac ([Only registered and activated users can see links. ]) - it's a free download.
    Install it
    Launch the program and click on "configure"
    On the new configuration screen, click "new"
    This will launch the "Virtual drive creator"
    Click next twice
    Type in any name you want and click next
    This will create a new virtual drive which appears in the list on the left of the configuration screen.

    Now click on your new virtual drive
    On the right section of the window, click on the "wine" tab.
    Then click command prompt
    This will launch a familiar windows CMD window.

    Put the gimgunlock.exe file in the same folder as the .img file you wish to unlock
    Navigate the command prompt to the folder where both the gimgunlock.exe file and the .img file are stored.
    (navigate using the usual cd.. and cd commands as per windows)

    Once in the correct directory (you can do a dir command to check), type gimgunlock.exe xxxxx.img (where xxxxx is the name of the img file)

    You will then see the command prompt spool through a whole list of stuff.

    Voila! IMG is unlocked.

    I've yet to figure out how to "package" the exe into a standalone .app which supports drag'n'drop of a .img file onto it. Whoever manages that will be a star!

    Can you compile and run it on Mac?

    Hi Guys i use a MacBook Pro.Is there anything out there i can use to unlock .IMG files on my Mac please

    Features of gimgunlock:

    * Direct Modification - unlike other tools which use GMapTool to split an image file, unlock each tile, then join all tiles; this tool unlocks all tiles in an image file directly without splitting and joining. Therefore, you should back up your original map first before running this tool.

    * Super fast speed - The 1st result of direct modification is super fast unlocking. For example, a 2.3 GB image file can be unlocked in less than 4 seconds.

    * Zero disk space - The 2nd result of direct modification is that no intermediate disk space is required. In fact, you can unlock a big image file on a SD card or USB connected GPS device directly and quickly.

    * Intact header - The 3rd result of direct modification is that the original header of the image file is preserverd. Thus, timestamps, version number, Mapset name, etc. remain the same.

    * Less memory used - this tools runs happily on Win32 without the need of 3GB switch.

    * Multi-platforms support - this tool is distributed with Windows binaries. But those who prefer to run on Mac or Linux platform can compile the source code by themselves.

    * Ease of use - to unlock, simply drag the image file over the icon of gimgunlock.exe, the dragged file will become unlocked. That's all. You can also run it in a command prompt window or batch file by supplying the pathname of the image file as the only argument.

    Download link of open source code (click on the tab ZIP)
    Code:
    Please Login or Register to see the links
    Download link of Windows binaries
    Code:
    Please Login or Register to see the links
    Note: the original binaries above cannot handle image files grearter than 2 GB. It is recommended to download the patched version as attached which can unlock any size < 4GB.

    Also Note: Gimgunlock assumes the first byte of an IMG file is zero. If not zero, the whole IMG file is protected by a very simple scrambling scheme via XOR (logical eXclusive OR operation). In such case gimgunlock will stop and prompt you to descramble the IMG file by the attached gimgxor.exe first.

    A Mac OS X version of gimgunlock v0.03 is added to post #1. Let me know if it works or not.
