Don't be so upset. The Mac platform is attractive to developers and users because it has a high level of openness (say, compared to the iOS), combined with elegant interfaces in the APIs and UI (compared to Windows). Apple will start losing customers if they make their platform less open. And if that happens, it will bring opportunities for competitors who can deliver openness on top of a platform that, for the user, sucks less than Windows.

On the other hand, if developers don't really care about the presence of open platforms, and are happy to work within the confines of Apple's new totalitarian empire, then the laissez-faire world of PC development will disappear. But does anyone really think that that will happen?

Maybe they're just xenophobic.

Look for somewhere that will allow you to be a jack-of-all-trades. My second job was as a casual tech support person at a university. While I was there I was able to branch out into a few different fields that interested me, one of which was programming. I was able to display an aptitude for it and a willingness to pick up new skills so that when I returned to them after a year of travelling they re-hired me as a full time programmer.

Universities are generally unable to offer the best salaries so they have to make themselves appealing to potential employees in other ways. In my case, they were less stringent about their requirements for qualifications and allowed me to develop my skills on the job. I've spent the last couple of years bluffing my way through at a software company so the experience was definitely worthwhile.

I don't think it's naive to expect other opportunities to appear but you just need to look for an employer who is going to offer them. And be willing to accept a lower salary in exchange for some good experience.
