Organizing fMRS .IMA files

I’m using conventional MRS. Currently, LCModel is installed on a different machine. I’m using Osprey on Mac, and LCModel is on Linux. Do I understand correctly from this thread that I would need to build LCModel for Mac? Or I can look into the possibility of doing everything from the Linux machine.

Edit to add: If I fit with LCModel through Osprey, can I specify control parameters like ATTH20 and WCONC?
