I am working in a mac application with snowleopard.This application is created with leopard os,but this not support in lion due to some external application.So we converted this to snow leopard and work fine .Now the client need to convert this application to leopard version ,for that i am using the xcode 4.2 and lion os and convert the bsec SDK to Mac osx 10.5 and Architecture to 32_bit intel ,but we getting an error "The run destination My Mac 64-bit is not valid for Running the scheme 'AppName'."
How can avoid this error ?
I want to test this application with 10.5 os, but we have only the 10.6 & 10.7 osx, 1)where we get the leopard osx ? 2)Has the Apple issue leopard osx now? 3)Is any problem for instal the leopard os to new MAC system(iMac,Macmini,Macbook)?
