Running on both Mac OS Venutra and Sonoma the 'Help/Check for updates' menu item in Rstudio (2023-06-05) has not had any effect. No error message, no freezing of software - just no response.
I had assumed the software hadn't been updated, but a manual check shows there is a current update from September; no idea how many updates have been missed.
I did not have any update push notifications during this period.
Ironically I did have update notifications on my work Windows machine - but am not allowed to update
