Mac Warning: Name is nonexistent or not a directory

I tried running a code I received from someone on both my M1 Macbook and Windows laptop. Without changing anything in Matlab, the code runs perfectly on the windows laptop. However, I am getting the Name is nonexistent or not a directory warning on my mac. Please see pictures below. I have made sure the subfolders are added to path under Set Path. I have also tried restoredefaultpath & savepath, and

>> edit pathdef.m. But they don't seem to work. Could someone please help?

Does the mac care about the direction of the slash in the path (Windows doesn't)? Try using all forward slashes. Try leaving off the training slash wherever you use it? How are you constructing the file paths in those folders? Are you using fullfile? If not you should.

Mac does care about the direction of the slash -- it must be / for the Mac.

I'm just wondering why there is a \ at the end of the path in the warning message

[Walter Roberson]

The user has incorrect addpath calls.

Ah ha! That solved the problem. Thanks all!
