Hi John,
I cannot replicate the problem on my machine, which version of R and
RStudio are you using?
I don't think I can solve the issue but it could help others to have a
finer idea about your system.
Also I used a terminal running bash outside RStudio, what did you do?
I did your test using RStu
When checking a package on MacOS High Sierra the XQuartz server starts up at
the "checking S3 generic/method consistency" step. This is easy to reproduce:
Start RStudio
Select New->Project->NewDirectory->R Package (I checked "use .git")
BuildPane->More->BuildSourcePackage
At the bas command line
