I inadvertently reset everything and now must reinstall OS. I rebooted while holding down command, option and R. On boot up, it found my WiFi, I entered my password and then a screen for OS X Utilities appeared. This time however the WiFi icon on top right hand corner is greyed out and I cannot reinstall OS X. Has anyone encountered and solved similar issue?
MacBook Air
Hey Ridgewood6,
We'd be happy to help out. Sounds like you need help reinstalling macOS on an Intel-based MacBook Air. For help with doing so, check out these steps below:
Start up your Intel-based Mac in macOS Recovery
1. Restart your Mac.
2. Immediately press and hold one of the following key combinations until you see the startup screen:
• Command-R: Start up from the built-in macOS Recovery System. Use this key combination to reinstall the latest macOS that was installed on your system, or to use the other apps in macOS Recovery.
• Option-Command-R: Start up from macOS Recovery over the internet. Use this key combination to reinstall macOS and upgrade to the latest version of macOS that’s compatible with your Mac.
• Option-Shift-Command-R: Start up from macOS Recovery over the internet. Use this key combination to reinstall the version of macOS that came with your Mac or the closest version that’s still available.
3. If you see a lock, enter the password for your Mac.
4. If you have multiple volumes on your disk, select the volume you want to recover, then click Next.
5. If requested, choose an administrator account, click Next, enter the password for the account, then click Continue.
When the Recovery app appears in the menu bar, you can choose any of the available options in the window or the menu bar.
Connect to the internet using Wi-Fi
If the Wi-Fi menu icon (in the upper-right corner of the screen) contains one or more bars, Wi-Fi is turned on and connected to a wireless network. If the Wi-Fi menu icon doesn’t contain any bars
, Wi-Fi is turned on but isn’t connected to a wireless network. If the Wi-Fi menu icon has a slash through it
, Wi-Fi is turned off. Wi-Fi needs to be turned on before you can join a wireless network.
On your Mac, do any of the following:
• Turn on Wi-Fi: Click the Wi-Fi menu icon, then choose Turn Wi-Fi On.
• Turn off Wi-Fi: Click the Wi-Fi menu icon, then choose Turn Wi-Fi Off.
• Join a network: Click the Wi-Fi menu icon, then choose a network. If requested, type the network’s password.
• Join a closed network: Click the Wi-Fi menu icon, then choose Join Other Network. Enter the network’s name and, if requested, the network’s password.
Once ready to proceed with reinstallation, work through these steps next:
Reinstall macOS
Under some circumstances, you may need to reinstall macOS. You can reinstall macOS while keeping your files and user settings intact.
1. Make sure you’re connected to the internet.
2. In the Recovery app, click Reinstall macOS Ventura, then click Continue.
3. Follow the onscreen instructions.
Important: When you’re asked to select a disk, select your current macOS disk (in most cases, it’s the only one available).
