I have a file with .mexglx and .mexw32 extension. I need to run this files in MATLAB R2012a 32-bit. Is there any possible converter available or any other solution to it.
Thanking you in Advance,

You cannot convert the compiled Mex files, but you can run them directly as if they were M-files. But the file extension must match your operating system and Matlab version, see and follow the "Tips".

Once you have a file with that extension you should be able to use it as a normal function.
Also Mac is a Unix system.

But it didn't help me either.

I have a similar issue. I need to run some functions that call two files having the extension "name1_mex.mexw64" or "name2_mex.mexw32".
I tried to replace these extensions with ".sh" but I get back an error saying: "Unrecognized function or variable 'name1_mex'."
Is there any solution to that?
Operating system: macOS 13.3.1
Matlab version: R2019b

Neither of those MEX-files will run on Mac OS. MEX-files are architecture specific and the extension indicates the architecture for which they were built. The file with extension .mexw64 is for use on 64-bit Windows and the .mexw32 file is for use on 32-bit Windows (and so can't be run on any release past release R2015b, the last release of MATLAB for 32-bit Windows.)
You will need to either ask whoever gave you the MEX-files to give you a file compiled for Mac, which should have the extension maci64 (if you're using an Intel-based Mac) or maca64 (if you're using the Apple Silicon beta), or ask them for the source code and create the MEX-file yourself using the mex command.
