[HOWTO] Recover from "asr: Couldn't personalize volume" in InstallerApp2ISO.sh

[Brother Bear]

For some installers, InstallerApp2ISO.sh aborts with a cryptic

asr: Couldn't personalize volume /Volumes/OS X Base System - State not recoverable.

I don't know why (or what this means) but you can still use the script (and/or the GUI) if you follow these steps:

1. Do a dry run. The GUI or the script will show the commands used in the dry run.
2. Create the temp directory. The GUI or the script will show you where the temporary files are created. They look something like this

   /var/folders/yz/_g96wy5s1_9f102yptfz2h2r0000gn/T/TemporaryItems/(A Document Being Saved By InstallerApp2ISO 4)/10.12.sparseimage

   The last item in the file path can be ignored, but the parent directory needs to be created.
3. Cut and paste each step that the dry run produces into the command line (i.e. Terminal.app). You may have to run it with administrator privileges (i.e. sudo). You still encounter the above error but you can just ignore it.
