I changed my Wi-Fi password and now MacBook Air won’t connect to the internet. It’s not asking me for the new password either. I’ve restarted my Mac and don’t know what else to do. Help?

Troubleshooting Mac Wi-Fi:

A few thoughts to try...

I. Clear the Temporary Internet Files:

• Cookies perform remembrance of certain site-entered data.
• Cache keeps a snapshot of the last time you visited a site.
• Go Here: Clear your browsing history in Safari on Mac - Apple Support

II. Restart your Router:

1. Power: off the router
2. Wait: 30 seconds
3. Power: It back on

III. Boot in Safe Mode:

[Hold Down: shift key, upon boot], In Safe Mode, Login Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait 30 seconds, and then boot up normally, attempting another update install. See more here: How to Use Safe Mode on your Mac - Apple Support

IV. Try a New Admin User:

What happens when you create a new administrator user, and log into it? Do you still get this error? If not, then it is likely an error with the current user. If so, then it is likely an error with your Mac.
