Google Chrome may not be able to keep itself updated - hit or miss

[atomczynski]

I have two scripts for Google Chrome and it's a hit or miss if Google Chrome will auto update itself or not.

Thoughts?

@atomczynski Just use Google's enterprise .pkg installer which sets up autoupdate in the postinstall (I'd provide a link, but I use AutoPkg to grab it)

[atomczynski]

If deployed "on top" of the current install, will it erase the user's profile (bookmarks, history, cookies)?

Is this available for all or only Google Enterprise customers?

[sdagley]

It just installs the app, so no problems running it on top of existing.

Here's the download page for the .pkg version of Chrome I mentioned: https://chromeenterprise.google/browser/download/ You should find info linked from that page regarding any restrictions on its use.
