Looks like here is the solution r-lib/devtools#379

I think the problem is the function call to windows function on line 258 of the MOP.R function, as this function does not exists on mac system (for mac its quartz()). One solution can be either erase this line or ask something like:

if(Sys.info()[['sysname']]=="Windows") windows()
else if(Sys.info()[['sysname']]=="Darwin") quartz() # For Mac
else X11() #for unix

Yes. Luis. We were discusssing the same.
