[R-SIG-Mac] incompatible lldb on mojave?

[Simon Urbanek]

Vince,

Apple no longer allows debugging of distributed apps - see R for Mac FAQ 10.17:
http://mac.r-project.org/bin/macosx/RMacOSX-FAQ.html#I-cannot-attach-debugger-to-R

Another (not recommended) work-around is to disable SIP.

Cheers,
Simon
