Serious problem with R on macOS

This is what I get after the current failure, where neither R.app nor the call from the command line work.


fernandodepaolis at MacBook-Pro-2 ~ % ls -l `which R`

lrwxr-xr-x  1 root  admin  47 Jun  5 10:23 /usr/local/bin/R -> /Library/Frameworks/R.framework/Resources/bin/R


fernandodepaolis at MacBook-Pro-2 ~ % ls -l /Library/Frameworks/R.framework/Resources/bin/R

-rwxrwxr-x  1 root  admin  9196 Apr 21 14:47 /Library/Frameworks/R.framework/Resources/bin/R



which is identical to what I got when it was working fine a couple of days ago.

Thank you

Thank you!! I will do that.

PS: No, no additional or different scrubbers/antivirus/etc have been added.

Hum...

Best I can think of is to take the hint (from Simon Urbanek) and move the .pkg file from Downloads and into another folder before installing. Some system cleaner-upper or virus checker could be moving stuff around. You haven't perchance some virus scrubber running which might be restoring your executable directories to a previous state?

You might want to make a note of the location and ownership of installed files, like in

Peters-Air:R pd$ ls -l `which R`
lrwxr-xr-x  1 root  wheel  47 Jun  6 17:41 /usr/local/bin/R -> /Library/Frameworks/R.framework/Resources/bin/R
Peters-Air:R pd$ ls -l /Library/Frameworks/R.framework/Resources/bin/R
-rwxrwxr-x  1 root  admin  9196 Apr 21 23:47 /Library/Frameworks/R.framework/Resources/bin/R

and then, if/when it stops working, see if files have disappeared or changed owner or permissions.
