error iso file the disk appears to be invalid

Good Evening:

I created an ISO using DVD Creator on my Mac when it was running 10.14.10. I could burn the ISO file to DVD using the burn to disk selection from the drop down menu. After upgrading to Mac OS 10.15, I tried to burn the same ISO file to DVD and I am getting the following error message: Could not burn “FILENAME.iso”. The disk appears to be invalid”. I then recreated the iso file under Mac OS 10.15 tried to burn it to a dvd disk and got the same error.

All help will be greatly appreciated!

Thanks Mark K.

I figured this problem out. You can still burn iso files to a DVD that gives you the error message: Could not burn “FILENAME.iso” The disk appears to be invalid”. Below are the steps you need to follow:

Make sure you put a DVD into the DVD drive.
Double click on the ISO. This should mount it in Finder as a drive and open up another window that contains the audio and video _TS files.
Click ONCE in that widow to select it.
Go the menu bar at the TOP of the screen and select File.
From the File drop down menu select Burn to disc.

Thats it! Please let me know if this addresses your issue.

Good Afternoon:

After thinking about this for a while, I was wondering if you could please try the following:

Insert a blank DVD into your disk drive.
Open up a terminal window.
CD (Change directory) to where you have the ISO file you are trying to burn.
Enter the following command and let me know if this works for you: hdiutil burn Filename.iso

I know this is not as elegant as being able to drag & drop or use the burn file from the drop down menu, but if it works, at least it is a solution, till Apple can get their act together.

I found this same problem yesterday when I tried to burn a couple of ISOs that worked perfectly fine last week before I did the catalina upgrade on Friday. :sigh:

Could not burn "CentOS-7.5_1804-x86_64-DVD.iso". The disk image is invalid. <OK> - No, this is NOT okay.. ;)

@Batman - That only works if the ISO can be opened. Linux ISOs cannot be mounted on the desktop but previously could still be burned directly to dvd as is.

"The following disk images couldn't be opened

CentOS-7.5_1804-x86_64-DVD.iso no mountable file systems"

pick any iso you want http://isoredirect.centos.org/centos/8/isos/x86_64/CentOS-8-x86_64-1905-dvd1.iso

I have several I had previous downloaded and I could never mount directly on the desktop after DiskUtil went byebye but could be burned directly to dvd that I can then use to boot and install on other workstations (until catalina).

To Batman-15, I tried you five point steps. It does not solve my problem, the disk does burn the files, but as multiple .VOB files that does not autoplay on a typical DVD/Bluray player, but shows up as multiple .VOB files that must be played individually.

I wonder if there is a third party app that will do the same function as the ISO burn in Finder?

Good evening, I just finished executing the steps that I sent you in my previous post using the CENTOS iso file that I downloaded. The burn procedure worked, the only abnormality was at the end after finishing closing the disc it reported the disc was not able to be closed properly. I tried the disc in a X 86 PC and it booted up with no problem and asked me to install the CENTOS. What type of file that you were trying to burn?

I used your 4 step instructions in terminal mode and it worked very well. Thank you very much. Of course, in terminal mode, I had all sorts of SYNTAX issues until I took a quick online terminal command 101 tutorial. It has been probably 20 years since I have used terminal mode. Considering that my first computer language was FORTRAN (yes, I am that old), it has been quite a while since I have used command lines. Of course, I still would like Apple to fix the original issue for .iso files.

Yes, I am having the same ISO issues trying to burn a DVD since I have upgraded to Mac OS 10.15, worked perfectly in previous Mac OS. I hope we can get an answer on this.

I’m currently at work. If you send me a link to the iso file so that I can download that file, I will look into it tonight and let you know If I can figure it out.
