Aloha.

My first thought is to check and see if you can run R from the command-line.  My second thought is to create a new user and re-install R under that user and see if it's your user environment or something system-wide.

Good luck.

*Subject: *Serious problem with R on macOS

Hello,

For a few months now, I’ve been having an odd and rather annoying problem. I use RStudio and it frequently cannot start R, producing the error message attached below. This is clearly not the, as I worked on it the night before or even just a few hours earlier. What is clear is that R is not available on my system, although all the files are still there (in /Library/Frameworks/R.framework). It could be that a critical file becomes corrupted, or the system can’t find it. I have not been able to determine whether that is the case, or which file could be affected. I might have re-installed R dozens of times in the last month. This is something that never happened in the previous more than 15 years of using R.

I’ve tried everything I can think of, and the problem persists…and haven’t found any satisfactory feedback online either.

Have you ever heard of a problem like this? Or do you have any suggestions?

Thank you so much for your support.
