Question to mac developers: Does Apple let you in any way develop/debug/test programs for older operating systems? If I bought a newly-released-today MacBookAir with Lion, but I want to develop software that would still run on 10.6 and 10.5 - what's the official (and unofficial) ways to do that?

We keep an older Mac Mini around running 10.4, 10.5 (and soon to include 10.6) for support of these older systems. We've also found that our universal binary has no issues whatsoever running on Lion, which is a relief as we still prefer Xcode 3.

Is that one mac mini per version or is there an easy way to set up multiple installs?

Xcode can always target one or two versions back. As for testing, you have two options:

1. Buy old hardware as a dedicated testing server and run the older operating systems on different partitions

2. Run the older versions in VMWare (10.6 can do this, but I'm not positive about 10.5)

If you don't have 10.6, it's still available for free through the Mac Developer Program.

It's quite easy to set it up to boot of an external drive; I've done that and had 10.4/10.5/10.6 all bootable off of one external drive (split into three partitions).

I'm very sceptical of this Mac App Store. As much as I like the idea (apt anyone? :-D) I am very disappointed by it's performance. Neither on SL nor on Lion does it let me update bought apps. Doing the "drag app to trash, click `install', empty trash" mumbo is not really my idea of "working".

If anyone has similar issues, or a fix, that would truly be great!

10.6 and 10.5 (server version) will happily (well, for testing, at least) run in a Virtualbox VM. The host OS have to be OS X server too but with the 99$/year you got also server license for free. Using server instead of desktop is not a significant difference if you don't start the server daemons... somewhat remembers me of NT workstation and NT server (many years ago). :)

Others have answered most of this question, but I'll add a slight addition to supporting 10.5. Since PPC is an unsupported platform, Xcode 4 does not include support for it. I end up using Xcode 3 just for PPC support for one of my projects.

MAS always updates my purchased apps. I have however heard of it declining to do so if you have, on some attached hard drive, a newer or same-version binary or installer. But have had no problems with MAS myself. YMMV.

I'm kinda hesitant to get this as they always change a lot... all those iPhone development tutorials are very specific to a certain version. It took me awhile to find out how to deploy an iPhone app for the newer Xcode.

Agreed. All my dev books are focused on XCode 3 and there are only a couple of XCode 4 books that have been printed. Which is disappointing because now my old books are useless and I spend most of my time replaying the Apple XCode 4 videos to figure out how to do certain things.

Create multiple partitions on the HD - 10.4, 10.5, etc.
