My apologies for muddying the waters. Yes, it's been so long that I've
worked on a Mac without XQuartz that I forgot to install it -- even
though the most common problem with the Rcmdr on Macs is failure to
But there's still a problem: With XQuartz installed and without the
developer tools, loading the Rcmdr or just the tcltk package produces
In system2("/usr/bin/otool", c("-L", shQuote(DSO)), stdout = TRUE) :
running command ''/usr/bin/otool' -L
had status 1
xcode-select: note: no developer tools were found at
'/Applications/Xcode.app', requesting install. Choose an option in the
dialog to download the command line developer tools.
and, as this warning states, a dialog box pops up offering to install
the developer tools.
I suspect that most users will respond positively and have to wait
through a potentially long download, even though tcltk and the Rcmdr
load properly if the offer to install the development tools is declined.

>> I discovered this issue when a user (cc'd above) wrote to me about having to install the macOS developer tools in order to use the Rcmdr package. I didn't encounter the problem myself because (of course) I have the developer tools installed. I was able to reproduce the problem by dusting off an old Mac without R installed and starting from scratch.
