Here's the thing: I have an ageing black Macbook, one of those cult objects with a 2.4GHz Core 2 Duo processor and 6GB of RAM. No multitouch and, worse still, a pathetic X3100 graphics chip. As a result, I can't install Mountain Lion. I'm stuck at Lion 10.7.5, which should be released in the next few days. I don't want to buy a new mac now and would like to extend the lifetime of this senile machine by 1-2 years by buying a new battery and a 256GB SSD, all in all at only $300. I don't mind the lack of Mountain Lion features but my questionlong story shortis this: Using Xcode, will I be able to build binaries for 10.8 on this old machine (assuming that I don't use APIs for features that aren't supported on Lion, e.g. notification center)? Thanks.
