Changing the startup disk on your Mac can seem intimidating, but it’s actually a straightforward process. All it takes is a few clicks in your system preferences, and you’re good to go. Whether you’re looking to boot from an external drive or just switch between different operating systems, this guide will help you get it done quickly and easily.
Step by Step Tutorial: Changing Startup Disk on Mac
Before we dive into the steps, it’s important to understand what changing your startup disk will accomplish. This process will tell your Mac to start up from a different disk than the one it usually does, which can be helpful for troubleshooting issues or if you’re running multiple operating systems.
Step 1: Open System Preferences
Open System Preferences from the Apple menu.
Once you’re in System Preferences, you’ll see a variety of icons. Look for one that says "Startup Disk" – that’s where you’ll be able to make the change.
Step 2: Click on Startup Disk
Click on the Startup Disk icon.
After clicking on Startup Disk, you’ll see the available disks that your Mac can start up from. If you’re not seeing the disk you’re looking for, make sure it’s properly connected to your Mac.
Step 3: Select the Disk You Want to Use
Select the disk you want your Mac to start up from.
You can only select disks that have a compatible operating system installed. If the disk you want to use doesn’t appear, you may need to install an operating system on it first.
Step 4: Restart Your Mac
Click the "Restart…" button to restart your Mac and boot from the selected disk.
Make sure you save any open files and close all applications before restarting, as this will close everything that’s currently open on your Mac.
After you’ve completed these steps, your Mac will restart and boot from the disk you selected. It’s that simple! Just remember, if you want to switch back to your usual startup disk, you’ll need to repeat these steps and choose the original disk.
