I was wondering if there was someone who could help me with this. I'm working with the PTM fitter (which I have downloaded) and I'm able to run through all the steps properly until I verify my path right at the end, but I'm getting a different error message than normal when it just can't find the fitter, so I'm not sure what it's actually getting stuck on and how I can bypass it. Here's the error message:

Hi there, Thanks for putting that up, but unfortunately there doesn't seem to be any file extension for the fitter for mac? Would you be able to perhaps re-upload it or provide that information?
