[R-SIG-Mac] FinderKit error message on starting up R

[Simon Urbanek]

Tim,

it is a benign warning due to two conflicting classes provided in the macOS system itself. You can either ignore it (see R for macOS FAQ 10.4 on disabling stderr forwarding in the R.app GUI)[1] or upgrade your macOS version.

Cheers,
Simon
