How to update a Mac
Updating your Mac keeps it safe and fixes bugs. It can take a while, so start when you don't need the computer for an hour.
This page is for you if
- A message says a macOS update is available
- An app says your Mac software is too old
Before you start
Apple says to back up your Mac before you update. If you're not sure your Mac is backed up, ask someone you trust to help you check first.
Do these steps
-
Step 1: Open System Settings
Click the Apple menu. It's the apple in the top-left corner of the screen. Choose System Settings.
-
Step 2: Go to Software Update
Click General on the left, then click Software Update on the right.
-
Step 3: Install it
If an update is there, click the button to install it. If nothing shows, click Check for Updates.
-
Step 4: Type your password
Your Mac asks for an administrator password. That's the password you type to log in to your Mac.
-
Step 5: Let it finish
Don't put the Mac to sleep or close the lid. It may restart and show a progress bar or a blank screen several times. That's normal.
Good to know
- Plug in a laptop before you start so it doesn't run out of power.
