## In no particular order. I'm pulling these from a bookmark folder, I'll work on labeling as I have time. Hope these help. Will be mixing in Linux reference as well. 

Sidenote: the macOS Internals series is amazing, although might be out of reach for some. However if having a hard time deciding (I definitely way) and in budget, In my opinion, they are worth the price. I've worked through Volume II, waiting on Volume III. 
As always, most of what we need in our world can be found open sourced and provided by some of the brightest, but it can be a frustrating journey finding material.

UPDATE

Although below are methods to extract the contents of a macOS package without actually installing it, the best way might be to create a blank disk image and install the package to this disk image in order to inspect the package contents. To do so:

• Open the Disk Utility app.
• Choose "File > New Image > Blank Image". Alternatively, simply press CMD-N.
• Set the parameters and click on "Save" to create the blank disk image.
• After creation, it should be already mounted. If not, you can mount it by navigating to the directory that it is placed at and double clicking on the disk image file.
• Run the package installer by double clicking on the package file.
• Select this newly created blank disk image as the destination and install it.
• If the script is preventing you from installing by saying, for example, "macOS isn't installed", you can:

There are a ton of different ways to split up a string in Zsh. This gist attempts to show them with examples to help you build your own. I write Zsh scripts all the time, and still reference back to this gist, so there you go.

From the Zsh docs on Parameter Expansion Flags (yeah - I know... how would anyone ever find that if they didn't know where to look!?)

j:string: Join the words of arrays together using string as a separator.
s:string: Force field splitting at the separator string.

You can also read more by running man zshexpn. (Again, I know, right!? How would anyone know to look there!?)
