We have a lot of software in our systems that's open source/Unix stuff. Typically it's done for Linux or BSD and ported by someone to OS X. I noticed in the "Security & Privacy" section of System Preferences the only two options to allow software installation are from the Mac App store or from registered Mac developers. Is there a way to change this or work around it? The only way to become a registered Mac developer is to pay the $99 for the "privilege" of working on OS X and then sign the product with Xcode. One developer who's stuff we use said he had no intention of signing up for Apple's program, which is apparently quite the red-tape festival, and if Apple didn't change it, he just wouldn't develop for it. I can see a lot of Linux/BSD/Unix developers, especially those working on open source stuff, being more than a little irritated by this. Apple wants them to pay $99 so they can distribute what they produce at no cost to anyone? It makes no sense. This is right up there with putting together hardware that can't be configured or upgraded by users. Is there any way to circumvent this…by disabling SIP for example?
