No, *.dll files cannot be made to run on the Mac. That is -- not when it's running MacOS. (But yes -- it's actually possible to get the Mac running Windows using a product called BootCamp).
The counterpart on the Mac to the dll is called a dylib. People who ship compatible Mac and Windows versions of their products have to produce compatible pairs of dylibs and dlls. For an example of a JAL app which works on both Windows and Mac, study the package: 'tools/regex' open 'regex' ...and search for the word: dylib and also: 15!:0 --which is J's calling interface to either a dll or a dylib, depending on your platform. This is identified to J by the noun UNAME_z_ , which on the Mac will contain the string: 'Darwin' (the programmer's name for the Mac system). On Windows it's 'Win'. Another good cross-platform app to study is the addon: 'math/fftw' open 'math/fftw' That's all I can say. Anything more needs specialist knowledge of the dll / dylib concerned.
