Is there a way to install Xcode 4.2 on OS X 10.8?

I need to compile some Firemonkey projects on my MBP (latest without retina) and I have OS X 10.8 installed and through normal means it's not possible to install Xcode 4.2.

  • Which are those normal means? – Thecafremo Mar 7 '13 at 10:01
  • Why can't you use the more modern Xcode 4.6 ? – user151019 Mar 7 '13 at 11:00
  • If the reason is that you need the 10.6 SDK take a look at this question: stackoverflow.com/questions/11989007/… – jaume Mar 7 '13 at 11:49
  • 1- without destroying my current setup, preferable legal since I actually "own" a "license" for both osx 10.7 and 10.8 2-firemonkey only works with 4.2, I have the 4.6 3-no, that's not the reason. – Jake Armstrong Mar 7 '13 at 13:15
  • Is Firemonkey this dev environment? If so what exactly does it need? – user151019 Mar 7 '13 at 14:12

No, you can't run Xcode 4.2 on OS X 10.8 (Mountain Lion).

Xcode 4.2 is available as a download from the developer site at Apple:

but it needs Lion.

On Mountain Lion, Xcode 4.2.x will show an error message similar to this, as mentioned here or here:

This installation of Xcode 4.2.x requires Mac OS X 10.7 Lion.

If you need Xcode 4.2 you will need to install Lion, preferably on an external harddrive to avoid overwriting your current Mountain Lion installation.

  • yes, but how did you get those results? – Thufir Mar 17 '15 at 1:53
  • @Thufir Honestly, I don't remember, my post is 2 years old. Why do you ask? – jaume Mar 17 '15 at 15:20

There's answer on Apple discussions groups to install Mac OS X Lion into virtual machine to use previous FM-ios.

PS: You're allowed to install Mac OS X in virtual machine on Apple hardware which meets requirements.
