Disk Utility on the MAc is one of those hidden gems which does so much however is hidden away and has a terrible interface which hides its features. Very un-Apple like. OSX Dail posted a really great guide on using it to convert file containers such as IOS and DMG.

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. Iso to exe converter free download - Free ISO Converter, Exe to Msi Converter Free, Free ISO to USB, and many more programs. Nov 02, 2017 Go to the Finder WindowOpen TerminalClick GO-Terminal. Then, type and enter the Following Command in the Terminal Window: hdiutil convert/folder/folder/file. Iso-format UDRW.

Need to convert a DMG disk image file to a CDR or ISO disk image format? Don’t bother downloading any third party tools, all you need for conversion is built right into Mac OS X and you don’t even have to go the command line route for most cases.

Converting a DMG to CDR

Going from DMG to CDR is as easy as it gets:

1. Mount the DMG disk image you want converted to CDR format by double-clicking it in the Finder
2. Launch Disk Utility found in /Applications/Utilities/
3. Select the .dmg image from the sidebar list and then click the “Convert” button in the toolbar
4. Pull down the “Image Format” menu and choose “DVD/CD master”, then click “Save”

Conversion happens very quickly and you’ll find the converted CDR file at the destination where you saved it. It’s also immediately visible in the Disk Utility sidebar if you want to do something else with the file.

Now if you want to get the CDR file to ISO format, there are a few easy ways to do that.

Converting the CDR to ISO the Easy Way

You can think of a .cdr as the Mac variation of a .iso disk image, and in fact you can often convert the cdr to iso just by renaming the file extension from the Finder. If you don’t have file extensions showing in Mac OS X you’ll need to do that first, then just rename the extension to .iso and accept the changes by selecting “Use .iso”.

It’s important to point out the file extension method typically works fine on a Mac but if you want to use the resulting image to burn a bootable disk, or burn it through Windows or Linux, you’ll probably want to go with the more complete method shown below.

Converting CDR to ISO via Command Line

Convert Cdr Files To Svg

If you want to be certain the ISO conversion and its headers are accurate, jump to the command line by launching Terminal, found in /Applications/Utilities/, and then using the following hdiutil command:

hdiutil convert /path/imagefile.cdr -format UDTO -o /path/convertedimage.iso

Be sure to plug in the correct paths for the both the input and output file.

Name	CDR	DXF
Full name	CDR - CorelDraw File Format	DXF - Drawing Interchange Format
File extension	.cdr, .cdt	.dxf
MIME type	application/x-cdr	image/vnd.dxf
Developed by	Corel Corporation	Autodesk
Type of format	Vector graphics	CAD
Description	CorelDraw is a vector graphics editor developed and marketed by Corel Corporation of Ottawa, Canada. CorelDraw file formats include CDR, CorelDraw Compressed (CDX), CorelDraw Template (CDT) and Corel Presentation Exchange (CMX).	AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a CAD data file format developed by Autodesk for enabling data interoperability between AutoCAD and other programs. Versions of AutoCAD from Release 10 and up support both ASCII and binary forms of DXF. Earlier versions support only ASCII.
Technical details	The CDR file is a ZIP-compressed directory of several files, among them XML-files and the RIFF-structured riffdata.cdr with the familiar version signature in versions X4 (CDREvrsn) and X5 (CDRFvrsn), and a root.dat with Corel Draw X6, where the bytes 9 to 15 look slightly different.	As AutoCAD has become more powerful, supporting more complex object types, DXF has become less useful. Certain object types, including ACIS solids and regions, are not documented. DXF coordinates are always without dimensions so that the reader or user needs to know the drawing unit or has to extract it from the textual comments in the sheets.
