I just run the installer pointed at an external hard drive partition. You can boot from that and run the OS installers for the same or later versions but you also have the full OS if needed, including extra apps like Carbon Copy Cloner or whatever, not just the recovery environment.

#12Disk Maker X [1] is a GUI which has been around a long time and does this. That said, it's closed source which could make a person justifiably twitchy when manipulating the installer. [1] http://diskmakerx.com

Open the .app in Script Editor. It's pure AppleScript, albeit with some do shell scripts.

#13It's not clear to me why this was made. We'll ignore the question of why you would want an ISO (you can write a DMG direct to USB, and Jamf, DeployStudio, etc, require a PKG...), and move on to optimization.
You can skip a lot of the convert/copy/asr steps by just using the hdiutil -srcfolder command, targeted to the createinstallmedia DMG, in conjunction with your target format. (This can be reproduced in Disk Utility as well, by the way.) As far as I can tell, you need about 3 commands here, and not a 189 line bash program with functions.
As mentioned elsewhere, Disk Maker X is the way to go. Thanks for sharing your work though, even if it's a bit over-built.

This isn't really accurate. It's not possible to find and download macOS releases older than the current release. The only exception I was able to find a few months ago is if you've already downloaded them once previously while signed into the App Store on a different machine. I believe in that case an old release can be downloaded on a new machine from the Purchased list after signing in under the same account.
EDIT: formatting; clarification

I just downloaded El Capitan today from the App Store from the same machine I installed from.

Yes, releases older than Sierra can still be found if you had previously downloaded them, but Sierra is gone and presumably High Sierra will be as well once it’s been replaced.

#19Couldn't you just use createinstallmedia that comes bundled with those Installers instead of using a 3rd party tool? https://support.apple.com/en-us/HT201372
This is basically a wrapper that handles the mounting process, different mac versions, etc.
