Reminder for MacOS users about running the RMCProfile fitting

[Kvieta1990]

These days MacOS seems to have more strict permission control on disk access. At least in my case, the default Terminal app does not have full disk access and while we try to execute the RMCProfile fitting from within GSAS-II, the terminal would always ask for login. Then we would just got stuck -- in my case, I am running on a lab-owned MacOS machine which requires PIN and Ybikey combo for logging in and when the terminal asked me for logging in, it turns out I could not log in using either the PIN, password or whatever.

To solve the issue, we need to go the settings, find Privacy & Security and further go to Full Disk Access and enable the Terminal app from there.

This issue actually should be created in the tutorial repo as well but it seems that the issue functionality is not available there.

This might work differently for some locations or MacOS versions. My recollection is that I get asked when I first run terminal if it should have disk access and if I say yes, I'm done. It may be that ORNL security settings prevent that from happening or it might be the latest (15.x) that is different.

I will create a VM with the latest MacOS so we can do tests of what will happen on a new install without site-specific security settings.

Thanks a lot Brian for taking care of this!

This is an ORNL specific thing, I believe. The thing is, when it is asking for login, for some reason (due to the Yubikey security PIN setting specific to ORNL, I think), I could not log in with anything, either password or PIN. None of them works and I just got stuck no matter how many times I tried. To me, the only way out is to go to settings and change the permission to let Terminal to have full disk access.

This is probably useful to other people, so I think it should be documented. The only question is what is the best way to do this? I could see doing it in a tutorial, but here is another choice: The RMC help page (source file MDhelp/docs/phaseRMC.md). Perhaps it makes sense to note it in both places with a link to whichever page has instructions on what to do.

It is probably best to keep the code/help/tutorials discussions all in one place.

sure, I will put it in both places. Thanks!
