[JUSTINMKAUFMAN]

Code was falling through to macOS 10 block for macOS 12 and higher.

Hey @JUSTINMKAUFMAN i would like to merge some of this in, but there's also a lot of extraneous files. For instance, some of your project configurations & paths as well as some of your Pod data files

I went ahead and cherry picked the initial commit and reason for opening the PR (fixing share contact). I definitely would like to look through the rest, but it's difficult to follow with the amount of commits and number of files changed. If possible, submitting seperate PRs with only changes for one specific feature/bugfix would be much appreciated.

I am going through the entire bundle and rewriting it (with proper support for Tahoe), so I will verify the cherry-picked changes and (likely) change the implementations to align with better code quality overall. Thanks for the contribution!

Reverting this to draft status for now in case you have time to revisit.
