I'm a total Xcode novice and have never used or installed it before. The goal is to compile code that will run on a PowerPC. Trying to use a machine thats faster than a G5 running a newer version of OS X than Leopard using a newer version of Xcode. Searching the web there are many guides, I've tried a few but none of have worked. Today I decided to try the XcodeLegacy script (https://github.com/devernay/xcodelegacy). The documentation tells you to download Xcode 3.2.6, Xcode 4.6.3, Xcode 5.1.1 , Xcode 6.4 (and I have). Then it says "install them in Xcode 4/5/6/7". Here is where I'm in need of some guidance . . . 1) I didn't download anything with 7 (Xcode 7) 2) Xcode 3 isn't doesn't (apparently) get installed 3) Where to install these versions of Xcode? Do I use the default path?
