R and RStudio incompatibility with Yosemite Mac OS X 10.10


There is currently a bug (or feature?) in the current version of Yosemite (OS X 10.10) that messes with the passing of environmental variables to programs launched from Finder (as pointed out by Adam Maxwell).

Notably, this means that PATH variables are not passed properly to or You may end up seeing errors such as the following:

Error in system("pdflatex", intern = TRUE) : error in running command
sh: pdflatex: command not found

Error in system("convert", intern = TRUE) : error in running command
sh: convert: command not found

Until Apple releases a fix to this, the easy workaround is to launch the desired application from the command-line (terminal).

For example to launch R, you can instead run


And for RStudio, you can run


Let’s hope Apple releases a fix soon.

  1. Hi Jon,

    We’ve fixed this on our end in the latest version of RStudio for OS X, available here:

    Give it a try and let us know if it works for you.

  2. Thank you, thank you, thank you! After re-installing MacTeX a couple times I was beginning to think I was crazy!!!

  3. Stuff like this should be referred to the r-sig-mac mailing group. It’s already been handled there, and seeing as the maintainer of OSX-R (Simon) runs that mailing list, you’ll get better info via that list.

  4. My RStudio is working fine with Yosemite. I must have the update.
