Burn ISO to DVD in macos 10.15 Catalina

https://support.apple.com/guide/mac-help/burn-cds-and-dvds-mchl8addfd95/mac says it works on Catalina, but when I select "Burn Disc Image" after selecting the .iso in the Finder, no windows opens, nothing happens at all. The same machine, a MacBook Pro (15-inch, Mid 2012) running Mojave works in exactly the same manner. (The two machines were exact copies of each other, except the amount of RAM, before I upgraded one to Catalina for testing.) The same thing happens on a vanilla install of Catalina on an iMac with a USB burner attached. I can't find anything interesting in the console.log either.


I know optical drives are not very common, but I still work with old computers and booting from USB is not always feasible. If it is planned not to work, then the option should be gone from the Finder.

MacBook Pro 15", macOS 10.15

If you are not afraid of the command line, you can burn ISO images from there where the Finder fails. For example, to burn the latest Ubuntu ISO, load Terminal.app, and there you would type the command (in bold; the resulting output is below):


hdiutil burn ubuntu-19.10-desktop-amd64.iso


Please insert a disc:

I submitted a bug through feedback assistant. I have noticed Etcher has problems writing flash drives as well. I finally ended up using dd to write to a flash drive.

I would recommend submitted a bug as well through feedback assistant so that it gets more attention at Apple.


You can get to feedback assistant but using the following applefeedback:// in a browser.

I have this exact same issue, and also with attempting to burn Solaris ISOs to cdroms. Yes, you can burn the mounted ISO disk image from the desktop drive icon when it's mounted, but it looks like it copies the files to the cdrom and doesn't make a bootable cdrom from the image.


Before Catalina this approach worked fine, same MPB 2015, same USB cd burner, right clicking the iso file and selecting 'Burn image to' ... on Catalina this option just closes the menu and nothing happens.
