In that case you'd do both yourself and those who depend on you for your contributions a favour by taking some of that time to get acquainted with alternative platforms seeing as how Apple seems to be on a course which will make it harder and harder to use their platform for this purpose. Like the Boy Scouts (used to) say, "Be Prepared!". Install a (few) Linux/BSD distribution(s) in a VM and try using those for a while to get a feel of the platform and its strengths/weaknesses so you have somewhere to land when the time comes.
