By default, your Mac starts up from its built-in hard disk, but a startup disk can be any storage device that contains an operating system compatible with your Mac. Auto tune the news app online. For example, if you install macOS on an internal or external drive, your Mac can recognise that drive as a startup disk. You can then follow the steps in this article to start up from it.

Use Startup Disk preferences

When you use Startup Disk preferences to select a startup disk, your Mac starts up from that disk until you choose a different one.

I use my mid-2012 11' MacBook Air for gaming and school work. My hard drive is filling up fast, and I was hoping I could use an external hard drive and Boot Camp to run Windows for my games, thus freeing up most of my hard drive.

Use Startup Manager

When you use Startup Manager to select a startup disk, your Mac starts up from that disk once, then returns to using the disk selected in Startup Disk preferences.

1. Press and hold the Option (Alt) key immediately after turning on or restarting your Mac.
2. Release the Option key when you see the Startup Manager window.
   If your Mac is protected by a firmware password, you can release the key when you're asked to enter the password.
3. Select your startup disk, then click the arrow under its icon, or press Return.
   If you press and hold the Control key during this step, your selection will be saved in Startup Disk preferences, so it will persist until you change it.

If your Mac is using OS X Lion 10.7.3 or later, you can also use this method to start up from your Time Machine backup disk. Startup Manager identifies your Time Machine backup as ”EFI Boot”.

If you can't select your startup disk or start up from it

Check for these possibilities if you can't see your disk in Startup Disk preferences or Startup Manager, or your Mac won't start up from it.

Check for a compatible operating system on the startup disk

Make sure your startup disk is using a version of macOS that is compatible with your Mac.

Mac Os Boot From External

To start up from an external disk with macOS Catalina 10.15 or later, the disk must be connected via USB-A, USB-C or Thunderbolt, not FireWire.

Check startup security settings

If you're using a Mac that has the Apple T2 Security Chip, check the settings in Startup Security Utility. These settings determine whether your Mac can start up from another disk.

Check for Option ROM firmware

If you're in Startup Manager and can't see a third-party startup disk, the startup disk could be using Option ROM firmware. To enhance system security, Mac computers with up-to-date software don’t display devices that use Option ROM firmware until you load their firmware. To do that, press Option-Shift-Command-Period while in Startup Manager. If your startup disk appears, do that each time you want to start up from it or from another disk connected to it.

If you're using a firmware password, the ability to load Option ROM firmware is disabled as an additional security protection.
