Location of the installer .app for High Sierra and higher

[matteosecli]

Hi, first of all thanks for this great tool! 🙂

I've had problems when making ISOs from installers of High Sierra and higher; the script was failing with the following error (though the GUI was saying that the process completed ok):

Erasing Disk: 0%... 10%... 30%... 100%...
Copying installer files to disk...
The copy of the installer app failed.

Mojave and Catalina were giving similar errors, basically saying the copy failed because they couldn't allocate space, but I believe the root reason was the same.

It turns out that my installers were stored in an external drive formatted as NTFS; while this seems to be ok when creating ISOs up to Sierra, it doesn't seem to be the case for High Sierra and higher (which, if I'm not wrong, require administrator privileges). I've solved by just copying the installers from the NTFS drive to somewhere on the internal storage of my Mac, just for the time required to make the ISO.

I don't know if the problem relates to external drives in general or to NTFS or non-Apple partitions, but I think it would be useful for other users to know about this possible issue, and to make sure to temporarily copy the installers to a native partition before running the ISO creation. Was thinking about some warning in the README or so.

Hello Matteo Thanks very much for the feedback. I'll take a look at at this. I must confess that Socratis and I never considered people using NTFS drives when we were working on this. Regards, Bryan
