session not created: This version of ChromeDriver only supports Chrome version 74 error with ChromeDriver Chrome using Selenium
I'm trying to run RSelenium using the rsDriver function, but when I run
rD <- rsDriver()
I get a message telling me I need a newer version of Chrome:
> rD <- rsDriver()

Selenium message:session not created: This version of ChromeDriver only supports Chrome version 74
(Driver info: chromedriver=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Mac OS X 10.14.3 x86_64)
Could not open chrome browser.
Client error message:
Summary: SessionNotCreatedException
Detail: A new session could not be created.
Further Details: run errorDetails method
Check server log for further details.
The error message appears to say that I need Chrome version 74.0.3729.6, but when I look in Chrome's settings, it tells me that I'm running the latest stable version (73.0.3683.75). Upon further googling, 74.0.3729.6 is a pre-release dev version of Chrome: do I need to install this in order to use ChromeDriver with RSelenium?
I'm not wedded to the idea of using Chrome, but I haven't been able to get rsDriver to use Firefox: when I specify browser = "firefox", rsDriver gives me the same error message about ChromeDriver not supporting my version of Chrome.

Answer
For MacOS chromedriver upgrade did the trick:
brew cask upgrade chromedriver
