[R-SIG-Mac] obsolete LaTeX software in "R CMD check" on Mac?

[Marc Schwartz]

Hi,

I will stand to be corrected, but from what I can tell, 'realpath' is not part of a default macOS installation, and would need to be installed from a third party repo (e.g. homebrew). 

There appear to be shell script incantations that would accomplish the same functionality, but in the end, in the absence of these approaches, there is not an easy way, under a standard macOS install, to trace through the layers of symlinks to the target file.

You can also do this manually via the Finder, by right clicking on the symlink and using Show Original to navigate as well.

Also, note that under Catalina, the default shell changed from bash to zsh.

Regards,

Marc
