I have the exact same problem. I have yet to find a solution.

Rstudio will not launch: "This site can't be reached 127.0.0.1 refused to connect"

See also: This issue should be fixed in the latest release of RStudio, but evidently it is not in your case. Can you try the following: export DYLD_INSERT_LIBRARIES=/Library/Frameworks/R.framework/Resources/lib/libR.dylib /Applications/RStudio.app/Contents/MacOS/RStudio and see if you have any better luck? I'm also curious whether having anaconda3 on the PATH is causing issues for you. What is the output of: which R on your system?

?

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

"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?

I am having exactly the same problem. Did you ever get this fixed?

[day7kim]

Nope, still a problem even with the newest releases for both R and R studio, so I have been using a different device for R. I would like to know how to solve this though.

[bshobe]

The problem crops up for people who have Cylance installed on their machines. Are you using Cylance? If so, go to the thread below. The suggestion to uninstall Cylance, reinstall R and RStudio, then reinstall Cylance should work.

Great! If that works, please circle back and mark a solution.

Hey @bshobe, I haven't been able to delete cylance due to some complications, but I believe it will solve the problem (saw the rsession was blocked by cylance). Thank you so much.
