To update Google Chrome on a computer or MAC, you can do the following:
Open Google Chrome
Click the three dots (⋮) in the top-right corner
Select Help > About Google Chrome
If an update is available, click Check for updates
When the update is complete, click Relaunch
If you don't see the Relaunch option, then your Chrome is already up to date.
On an Android device, you can update Chrome by doing the following:
Open the Play Store app
Tap the profile icon in the top right
Tap Manage apps & device
Under "Updates available," find Chrome
Tap Update next to Chrome
Chrome updates are usually automatic in the background. However, if you're having trouble updating Chrome, you can check your antivirus, firewall, or parental control software settings. Make sure that software updates aren't blocked from going online.
