So, your Mac won’t remember your Wi-Fi passwords? And you are tired of manually inputting passwords for the Wi-Fi networks at home or work? In this post, I’m going to show you a few tricks that may work. By the way, I’m on a MacBook Pro that runs OS X El Capitan. The other Mac models and OS X versions are supposed to work as well.
Tip 1: Make sure you checked “Remember this network”
Check this only for Wi-Fi networks that you trust, for example, at home or in the workplace. After you input the right password, check the remember this network option below “Show password”. Then click the blue “Join” button to continue.
Tip 2: Delete Keychain and retry
Do this only if tip 1 doesn’t work out, or your Mac fails to memorize the passwords for other reasons.
Step 1: In the Spotlight search box, type “Keychain Access”, double click the first result.
Step 2: A new window pops up, under “System” (on the left panel), select your Wi-Fi network, right click and delete it.
Step 3: Now re-join the network and don’t forget to check the “Remember this network” option as I showed in tip 1.
Tip 3: Reset NVRAM
If your MacBook is suffering some other issues such as your Mac is super slow to start up, Bluetooth won’t work, screen resolution not display properly, etc. besides won’t remember WIFI passwords issue, resetting NVRAM may help. Note: this tip originates from an Apple Discussion. Personally, I haven’t suffered the issues above.
Resetting NVRAM is harmless, and it only takes a minute. Follow the guide in this Apple support article, or watch this YouTube video:
That’s all. Let me know if these tips help.
