Can't run Google Chrome on macOS Sierra For some reason, no matter how many times I delete (using AppCleaner) and redownload Google Chrome, I am unable to launch Chrome on my 2017 MacBook Pro running 10.12.6 Sierra.

When I click on the application, it's icon appears momentarily in my Dock and then disappears.  I am using Firefox, downloading directly from Google Chrome's website.



This is what appears in my system log when I try to run the application:

Does anyone know why I might be having this problem? It's making it difficult to test UI code.
If you just deleted the app from the applications folder there may be some remnants hanging out in other places like pref files and other places in the ~/Library/Application Support folder.  Try downloading an app like AppCleaner
http://freemacsoft.net/appcleaner/
Drag the app onto its window and it will find the associated files for Chrome.  Then hit the delete button, and then re-download Chrome and try it again.  Hope that helps.
