After the system automatically checks for updates, you can click "Upgrade" to download and install. Prepare before update: 1. Back up data using Time Machine; 2. Make sure that the power is sufficient or the power is connected; 3. Turn off the background program; 4. Make sure there is enough disk space.

Updating macOS is an important operation to keep your computer safe, stable and up-to-date. If you find that the system prompts that a new version is available, or want to actively check for updates, the whole process is not complicated, but there are several key points that need to be paid attention to.
How to check macOS updates
macOS comes with its own system update tool, which can be found directly in the settings:
- Open System Settings
- Enter General → Software Update
- The system will automatically check whether there are updates available
If you see an update prompt, the updated version number and main improvements will usually be listed next to it. Click "Upgrade" to start downloading the installation package.
Note: Some updates may require closing certain apps or logging out the current user first, so it is recommended to update when it is idle.
What should be prepared before update
Before a formal update, preparing for a lot of problems can be avoided:
- Backup data : The most recommended way is to use Time Machine to backup to an external hard drive
- Ensure sufficient power : The power cannot be cut off during the update of the laptop, it is best to plug in the power supply
- Close unnecessary background programs : This reduces the risk of update failure
- Confirm that the disk space is sufficient : Large version updates usually require about 20GB of spare space
If the power is accidentally cut off or forced shutdown, it may cause the system to be damaged or even fail to turn on. So it's really important to prepare in advance.
Frequently Asked Questions and Solutions
Sometimes updates are not smooth sailing, and you may encounter some minor problems:
- Slow download speed : You can try changing the network environment, or use the "combination update" package provided by Apple
- Cannot start after update : try restarting a few times. If not, you can reinstall the system in recovery mode.
- Stuck in the update progress bar and remained moving : if there is no response for more than 1 hour, you can press and hold the power button to force restart, and then enter the recovery mode to repair
If an old device upgrades to a new system, compatibility issues may occur, such as the driver does not support it, some software cannot be opened, etc. At this time, you have to weigh whether it is worth upgrading.
Basically that's it. Although updating macOS seems simple, paying attention to details can save you a lot of trouble.
