[R-SIG-Mac] Problem R-4.0 beta and Rmpfr (pre-release)

[Simon Urbanek]

... I should add you can remove the serial number from the output, I need mainly the Processor and Model lines so something like:

      Model Name: Mac mini
      Model Identifier: Macmini8,1
      Processor Name: 6-Core Intel Core i5
      Processor Speed: 3 GHz
      Number of Processors: 1
      Total Number of Cores: 6
      L2 Cache (per Core): 256 KB
      L3 Cache: 9 MB
      Memory: 16 GB


Thanks,
Simon
