I am responsible for a Delphi/Win32 project management application. I have just completed a move to Delphi 2009.
More and more US based users want to use the application on their Mac computers, while the majority are Windows users.
Are there solutions out there to easily build a Delphi app that will natively run on MacOS?
With the release of RAD Studio XE2 in late 2011, Delphi developers should be able to build once and distribute on Win 32/64 and MacOS 32, with iOS support promised.
Mac OS X doesn’t run Windows programs. It doesn’t provide any of the API you’d need, such as the functions in kernel32, user32, etc.
You could try running your program via Crossover. Other options include virtual machines, such as VMware Fusion and Parallels.
Another thing you might try is to use .Net. Convert your program to use the .Net version of Delphi and then run it on Mono on the Mac. I wouldn’t put a lot of confidence in this method, though.
