Looks ok for now. The things I've noticed are:

1. Replace the static functions functionName (prefix underline) with functionName (suffix underline), to be consistent with the rest of code.
2. Replace the TODO's with TODO Mac.

1. Good eye Alex for the underscore.
   Suffix underline is for member variable which the static functions are not. So we'll be using the prefixed underline for the private static functions. The others should have been changed but went in because the framework needed to be merged. All future private static functions that we create for callbacks will be with the prefix. And existing one should be modified as we go, there is also a Jira issue that was created to track the issue with the original ones to be changed to prefix underscore.
2. We need TODO Mac for shared files with Appcel, as these are new files that we control, the Mac part is not necessary.
