 No, no… I don't disagree with you. I am just not very well versed in the
 usage of the availability macros you mention. I have mainly been active
 here, submitting tickets, fairly recently as things have started to break
 much more often for me. Possibly because I am still using a legacy OS. I
 just shared what solutions I applied to solve the problem for me. The
 solution is in no way, shape, or form made out to be an ideal solution,
 but it works. I personally consider it a workaround.

 Indeed, that was the point of getting rid of it :)

 As for the availability macros, thank you for the example. I will have a
 look at your suggested reading for the next time something like this comes
 around. It would probably be good to learn how to do this.

 (And if I have the time later today or tomorrow I may revisit this and see
 if I can figure out how to do this for iTerm2. Unless someone else beat me
 to it.)
