This has some improvements that -- I believe -- are unrelated to this task and would make the PR easier to review if they were split out (e.g. removeAppLauncher, removeStartupEntry). @Vzor- can you please split this PR into two PRs so that we can take advantage of the refactor?

With regards to the Mac security stuff, I think it's still a good idea to add this if the efforts are fruitful. I understand that merging the Mac security stuff does not close #1076, however I believe the approach of using MacOS native libraries to be more professional approach at installing our certificates.

Agreed. It may take a couple of days until I'm back on this issue.
