I have an old Apple Mac 32-bit, running Mac Yosemite.
I have Lazarus 1.4.2 and FPC 2.6.4 installed. I can compile an application (done an application bundle, MyProject.app) OK with it and it runs fine and I'd like to release it. But I have no way of knowing if it will run on 64-bit Apple Mac systems because I can't just download and install a 64-bit Apple Mac OS and run it in a virtual machine.
Can anyone tell me if, like a 32-bit compiled Windows exe, it will simply run in a 32-bit mode on a 64-bit OS or will it fail to run at all, like on Linux systems, wherein I have to create a 64-bit binary on my main PC and then a 32-bit version on a 32-bit Linux virtual machine.
