How can simulate a run on a older OS X version ?
Right now my app works on 10.7 and 10.8 but I want to make it compatible with 10.6. Since I’m using some new apis I’m still compiling with the 10.8 base SDK, I can only change the deployment target.
So on my OS X 10.8, how can I simulate a run on OS X 10.6 ? (If it’s possible)
Thanks
TheZ mentions virtual machines. Lots of hoops to jump through with licensing.
My personal "path of least resistance" was to use an old PPC Mac Mini and an almost-as-old intel-based. PPC runs 10.4 for old app testing; Intel mini boots various OS versions with which to test. All install images are disposable and can be restored from a network volume for a clean environment no matter what I do to it.
If you don’t care about PPC, then just get a used Intel Mac Mini, partition it for the older OS versions and use it exclusively as a test environment.
2022 Update: Apple has relaxed their stance on virtualization. Today I use VMWare (Parallels works too).
