Hi I used the "macOS Mojave ISO creator" script created by thelamehacker published on github.com I attach link, it created me mojave iso, burned, works perfectly, I would like to create bootable dvd for Catalina, does anyone know if the script exists also for Catalina ?

 

https://github.com/thelamehacker/macOS-toolkit/blob/master/toolkit/macOS_Mojave_ISOMaker.sh

change everything is written "Mojave" to rename "Catalina", it should work. presumably it will cause problems with "HFS + Journaled" and will not work properly after installation. So I would change it to APFs from begin.

macOS-toolkit-Catalina-master.zip

check it out if it works

HFS+ should not be a problem for an installer. It's the target disk/partition that gets converted to APFS at installation.

 

@Solaris82 Read the script and make sure you fully understand all of the steps. Do consider the allocated disk space given that a more traditional Catalina USB installer requires a 16GB key...

Of course, the problems only arise after the installation such as installing programs etc. or updating would be problematic with "HFS + Journaled".

But it could also be, that I did not enter the exact name of the Catalina app correctly into the script. please check the exact name of the catalina app with the entries in the script.
I am currently working on Windows OS and cannot check it on macOS Terminal

Guys, seriously! A little brain effort... It's obviously a problem of target image size as I stated above. Shouldn't take a genius to realize that.

 

It's even more surprising that the OP hasn't thought of posting a copy/paste of the error message.

I reissued the command, it created iso files but in the script it reaches 70% gave this error " 

  1. Copying to disk: 0%... 10%... 20%... 30%... 40%... 50%... 60%... 70%...
  2. Error: Error Domain=NSCocoaErrorDomain Code=512 "Unable to copy “InstallESD.dmg” to “SharedSupport”." UserInfo={NSSourceFilePathErrorKey=/Applications/Install macOS Catalina.app/Contents/SharedSupport/InstallESD.dmg, NSUserStringVariant=(
