How to update chromedriver to the latest version on MacOS using homebrew? - macos

Question

My current version is 81.0.4044.69 and I want to update to the latest version 83.0.4103.39
When I open Terminal and I do:
brew cask install chromedriver
It says:
Warning: Cask 'chromedriver' is already installed.
How can I update to the latest version 83.0.4103.39?

Answer 1

UPDATE: Now you can also do:
brew update
brew upgrade chromedriver
or
brew update
brew upgrade --cask chromedriver
Also be aware that after each upgrade you will get again a system warning when using the chromedriver for the first time so you need to click Cancel in the warning and then go to "Preferences => Security & Privacy" and click "Allow Anyway" to accept the risk. Then on the next run, you'll have to click "Open" once.
Note: The answer below was given for an older version and may not work anymore
I found out that I should do:
brew update
brew cask upgrade chromedriver
Another option is to uninstall and install it again like this:
brew cask uninstall chromedriver
==> Uninstalling Cask chromedriver
==> Unlinking Binary '/usr/local/bin/chromedriver'.
==> Purging files for version 81.0.4044.69 of Cask chromedriver
brew cask install chromedriver
==> Downloading https://chromedriver.storage.googleapis.com/83.0.4103.39/chromedriver_mac64.zip
######################################################################## 100.0%
==> Verifying SHA-256 checksum for Cask 'chromedriver'.
==> Installing Cask chromedriver
==> Linking Binary 'chromedriver' to '/usr/local/bin/chromedriver'.
🍺 chromedriver was successfully installed!
Now:
chromedriver --version
ChromeDriver 83.0.4103.39 (ccbf011cb2d2b19b506d844400483861342c20cd-refs/branch-heads/4103#{#416})

I would recommend start using webdriver-manager:
pip install webdriver-manager
what I prefer mostly and use it like:
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())
with that package you should not worry about version of chromedriver, even though, you can even choose particular chrome driver version:
driver = webdriver.Chrome(ChromeDriverManager(version='86.0.4240.22').install())
it is not the solution of the ticket, but it makes live easier working with chromedriver

Answer 3

Now its just brew upgrade chromedriver no longer cask

Answer 4

Uninstalling & installing the chromedriver worked -
brew uninstall chromedriver
brew install --cask chromedriver

Answer 5

I have recently have issues where I would receive a warning about chromedriver's developer not being trusted. To resolve this I use brew info chromedriver which gives the directory for chromedriver. Change into that directory and type ls -l and if the code like drwxr-xr-x has an # at the end, that means your mac has quarantined that file. To pull it out of quarantine, type xattr -d com.apple.quarantine chromedriver. Then you should be good to go.

Answer 6

When I initially ran the following commands,
brew upgrade chromedriver
brew upgrade --cask chromedriver
brew uninstall chromedriver
I got the error below.
Error: Cask 'chromedriver' is not installed.
So I had to remove the chromedriver not managed by Homebrew first.
rm `which chromedriver`
After that, brew install chromedriver successfully installed the latest version.
