macOS Xcode built app wont run on 10.5.8

[Tomas Sinkunas]

Hi guys. I am new here and new in Xcode world.

I made a simple app with Xcode 3.2 on Snow Leopard.
The resulting built app works on snow leopard, however it will not even start on leopard (10.5.8) - I get message "You cannot use this version of application with this version of Mac OS X". Is it normal?

Or is there a way to make app that will work both on Snow Leopard and Leopard? Please advise, as I have no way to find out myself

Thanks for any input

Oh come on now, that's simply not true. This is covered in the documentation. You just have to read it.

For example Tech Note 2064 is pretty helpful. As is the SDK Compatibility Guide.

Thank you for your help.
All I did was selected Targets - MyApp - Get Info and under Build tab i changed "Mac OS X Deployment" from "Mac OS X 10.6" to "Mac OS X 10.5" and it seems it works.

As my app is super simple and there's no difficult stuff, algorythms and nothing, it's just like a calculator with some text fields and buttons and that's it. So I assume I can even go lower to version 10.4.

Any ways, appreciate your input.

Cheers.
