Remember. Friends don't let friends use Macintosh.

     It's been a while since I've used any product made by Apple. The most recent I've used being the Apple //c. When they decided they wanted to lock down their machines so that regular people couldn't write software for them, I decided I didn't want to have anything to do with their machines. Linux always has and always will come with a compiler and assembler built in. (You need them to install new software. The same source will work on different versions of Linux. But the same binaries won't.) For Windows, Microsoft out of the goodness of its heart because there are other compilers and assemblers available for free, offers a fully functional compiler and assembler at no charge -- although they would prefer that you upgrade to one that you actually pay them for. Before that, DEBUG allowed the writing of programs. Even if it wasn't particularly convenient.
