Problem
I had to get some files onto a server today that had no internet access. I did have iLO access, so if I could get the files into an .iso file, I could present that as a virtual CD/DVD drive, and install the software I required.
But how to create an .iso file on my mac?
Solution
It’s a two step procedure, first you use Disk Utility to create a CDR image, then you convert that image to an ISO.
Launch Disk Utility > File > Image from Folder > Browse to and select the folder containing your files > Set the ‘Image Format’ to DVD/CD master > For ease I’m saving it on my desktop.
This will create a CDR disk image, to convert it to an ISO image, open a terminal windows and use the following syntax.
cd ~/Desktop hdiutil makehybrid -iso -joliet -o -FILENAME.iso FILENAME.cdr

Thanks Much! I was able to make a Custom Windows 11 ISO with no TPM 2.0 requirement(SUCH BULLCRAP!) for my 2015 iMac.

It’s also free, don’t pay AnyToISO 30 doll hairs for a license!

Simply rename the file and remove .cdr extension and use .iso extension works fine too….

No, it’s not the same thing. It works only because the file still have leftovers of signs it is .cdr and the app opens it as .cdr
