Hey, thanks. I followed the instruction and still would not show up. But in the terminal it says:
Macs-MacBook-Air:~ macuser$ export DYLD_INSERT_LIBRARIES=/Library/Frameworks/R.framework/Resources/lib/libR.dylib
Macs-MacBook-Air:~ macuser$ /Applications/RStudio.app/Contents/MacOS/RStudio
[35828:3664666:20200707,094405.682274:WARNING process_memory_mac.cc:93] mach_vm_read(0x7ffee431f000, 0x2000): (os/kern) invalid address (1)
[35828:3664666:20200707,094405.825797:WARNING system_snapshot_mac.cc:42] sysctlbyname kern.nx: No such file or directory (2)
"Uncaught TypeError: Cannot read property 'notifyRCrashed' of undefined"
Also when I tried "Which R", <- the second instruction from the link
Macs-MacBook-Air:~ macuser$ which R
/usr/local/bin/R
Any insights to these?
