TweakingAllPage 1 of 1&nbsp;&nbsp;22DMG&nbsp;files are very common on the MacOS X platform, used for Disk Images. With Disk Images we mean a full “copy” image of for example a CD, DVD or Harddisk. DMG‘s&nbsp;are typically used to distribute applications.Some times however you’d prefer a ISO&nbsp;or a CDR&nbsp;image instead, for example for users on different platforms, or for offering other ways to burn an image to CD or DVD (if applicable).In this article I’ll show you how you can convert a DMG file to either CDR&nbsp;or ISO under MacOS X, Windows or Linux.Please consider disabling your ad blocker for our website.We rely on these ads to be able to run our website.You can of course support us in other ways (see Support Us).When trying to convert a DMG to a ISO or CDR file for MacOS X, we have two options available.The first one is by using just Disk Utility, a preferred method if you don’t like working with Terminal.The second method is by using the command line by using Terminal.To keep the article complete, I’ve added a method for Windows and Linux as well.After converting a DMG&nbsp;to ISO, the ISO file can be burned on different platforms using popular burning applications like for example Nero under Windows.Note&nbsp;: ISO images, just like DMG images, can be mounted as a drive as well under MacOS X – no special software needed, just double click the ISO file.Please consider disabling your ad blocker for our website.We rely on these ads to be able to run our website.You can of course support us in other ways (see Support Us).My own little tool, ApplePi-Baker, originally intended for Raspberry Pi disk images, can assist in this as well.Obviously you will need to download and install ApplePi-Baker first, and after that follow these steps:Mount the DMG file by double clicking it. The DMG should now appear as a “disk” in Finder.Start ApplePi-Baker and located the mounted disk. This can be done in two ways:Option 1: Click the “” in the “” section.A list will appear, and you should see your “” – select it.ApplePi-Baker – Select Mounted DMGOption 2: Open the and find the “” disk.When found double click the “” line to select the disk.ApplePi-Baker – Advanced View – Select Mounted DMGNow select “” and in the file dialog set the “” to ““. In a matter of seconds you will have a IMG of your DMG file.Note: the IMG can be substantially larger, since some DMG files use compression, and IMG files do not.When using Disk Utility you will have to keep in mind that Apple uses the extension CDR for ISO&nbsp;images. In the end CDR and ISO&nbsp;files are the same, they just have a different extension. Renaming a CDR file to ISO&nbsp;afterwards will fix that.The steps are straight forward:so it mounts.Open ( &nbsp;).and select the “” option.Disk Utility – Right click mounted GMD image and choose ConvertIn the dialog that now opens, set the “” to “” and click ““.Disk Utility – Select format and click SaveAfter the converted file has been saved, locate it and . For example if you saved it as “example.cdr” then now rename it to “example.iso”.Please consider disabling your ad blocker for our website.We rely on these ads to be able to run our website.You can of course support us in other ways (see Support Us).Some of us prefer the command line, I for one often forget the details of the particular thing I’d like to do so I find myself using the first option more often.Start ( &nbsp;).Type:hdiutil convert pathtoexample.dmg UDTO pathtoexample.isoHere &nbsp;&nbsp;and &nbsp;&nbsp;are the paths to the files obviously.After pressing , it will take a few seconds and after completion you will find your iso file with an additional .CDR extension. Simply .example.iso.cdr example.isoFor Windows we need a little free tool called DMG2IMG, a successor of DMG2ISO.As usual the file can be downloaded from&nbsp;TweakingAll, but I strongly recommend going to the developers website to grab the latest version.Filename:&nbsp;dmg2img.zipPlatform:&nbsp;Microsoft WindowsVersion:&nbsp;1.6.7File size:&nbsp;64.5 kBDate:&nbsp;2017-02-09&nbsp;Download Now&nbsp;Send me a cup of Coffee&nbsp; &nbsp;&nbsp;After downloading and unzipping the file, the usage in a DOS box is simple.For DMG to ISO:dmg2img example.dmg example.isoFor DMG to IMG:dmg2img example.dmg example.imgPlease consider disabling your ad blocker for our website.We rely on these ads to be able to run our website.You can of course support us in other ways (see Support Us).A tool like DMG2IMG is also available under Linux, in Ubuntu for example, the easiest way to get it is:12dmg2imgThe command line use again is simple:For DMG to ISO:dmg2img example.dmg example.isoFor DMG to IMG:dmg2img example.dmg example.imgYour support is very much appreciated, and can be as easy as sharing a link to my website with others, or on social media.Support can also be done by sponsoring me, and even that can be free (e.g. shop at Amazon).Any funds received from your support will be used for web-hosting expenses, project hardware and software, coffee, etc.Thank you very much for those that have shown support already!It's truly amazing to see that folks like my articles and small applications.Please note that clicking affiliate links, like the ones from Amazon, may result in a small commission for us - which we highly appreciate as well.Please consider disabling your ad blocker for our website.We rely on these ads to be able to run our website.You can of course support us in other ways (see Support Us).Please consider disabling your ad blocker for our website.We rely on these ads to be able to run our website.You can of course support us in other ways (see Support Us).There are 22 comments.

So [-s] means that you can optionally add the ‘-s’ parameter for silent mode.For example using the silent (-s) mode:dmg2img -s example.dmg example.isoReplyJan 4, 2021 - 12:04 AMComment Linki convert the dmg but the disk utility saves it as .cdr file not isoReplyJan 4, 2021 - 6:34 AM - Author:Comment LinkHi Mian,As far as I recall, you can rename the .CDR file to .ISO. (see also step 3 in the Mac solution, where I simply rename the CDR file)Unfortunately, I do not know what OS and tool you’re using, but most allow you to define an output file name (eg. output.iso).ReplyJan 4, 2021 - 10:16 PMComment Linki do it but the iso file did not boot up. and i am usimg mac os sierra. and i use the disk utility to convert the dmg file .ReplyJan 5, 2021 - 4:57 AM - Author:Comment LinkCould it be that the DMG you’re using is not intended for booting?Most DMGs are not setup to be used for booting from.&nbsp;ReplyJan 16, 2021 - 2:51 PMComment LinkAfter hours of researching and downloading, I finally get it together and….dmg2img v1.6.7 (c) vu1tur (to@vu1tur.eu.org)ERROR: dmg image is corruptedReplyJan 17, 2021 - 5:28 AM - Author:Comment LinkHi Jack,One thing to keep in mind is that DMG2IMG may be aging. Apple does occasionally add new features to the DMG format, for example a new compression format, which then may be considered “damaged”.Having said that, a possible trick to convert a DMG to an IMG on a Mac (I assume you have a Mac available, since this article was written for MacOS);1. Mount the DMG by double clicking it.2. Download and install ApplePi-Baker.3. In ApplePi-Baker, find the mounted disk (possibly in the Advanced View – click the little harddisk icon).4. Make a backup of that disk – this will result in an IMG or a compressed IMG.Hope this helps, if the DMG is indeed corrupt then obviously this may not help either.ReplyJan 17, 2021 - 6:01 AM - Author:Comment LinkBased on your question, I’ve added an explanation for the ApplePi-Baker approach as well.ReplyJan 17, 2021 - 6:01 AM - Author:Comment LinkUPDATE:Method added by using ApplePi-Baker to convert and DMG to an IMG.ReplyAug 20, 2021 - 10:33 AMComment LinkThis worked great.&nbsp; I just copied the .dmg file to the directory of the tool.&nbsp; I used powershell and changed the directory to the location of the tool.&nbsp; I hate to use the tool full name to include the file extension.&nbsp; i.e., dmg2img.exe .\sourceFile.dmg .\destinationFile.iso  and it ran successfully.&nbsp;ReplyAug 20, 2021 - 10:54 AM - Author:Comment LinkAwesome, that is great to hear!
