How Does macOS Update Work?
Once you've enabled automatic update notifications on your Mac, you'll be informed every time Apple releases a new macOS version. To install a recent macOS version, you can navigate to the Apple menu > System Preferences > Software Update, where you'll find two options for installation.
To get a macOS update, you can also access it through the App Store.
- Update Now
Now refers to updates within the same current system version, such as from Monterey version 12.1 to Monterey 12.2.
- Upgrade Now
Upgrades refer to updates between two different versions of an operating system, such as from Catalina to Big Sur, or from Big Sur to Monterey.
Installing the available update for macOS Monterey on a Macbook can take around 35 minutes to several hours, depending on the health and performance of the Mac disk. This update also keeps other Apple apps like Safari, Messages, Music, Photos, FaceTime, and Calendar up to date.
Before proceeding with either update option, it's crucial to create a backup of your personal data, as a regular update may not be enough to safeguard it. Never rely solely on a machine to protect your data - trust yourself to take proactive measures to ensure its security.
When macOS Update Causes Data Loss
We highly recommend making a copy of important files on a Mac using Time Machine or reliable third-party Mac backup software, as upgrading to a new major macOS release can potentially damage the hard drive, resulting in lost data.
27% of Mac users have experienced unexpected data loss during a macOS update, with over 90% of the causes attributed to insufficient free space on the internal hard drive.
10% of data loss cases are due to interrupted and failed macOS updates, resulting from various errors. This is a separate scenario from the 90% of data loss cases caused by user error, accidental deletion, or other factors. The remaining 10% of cases are a result of the specific issue of interrupted and failed macOS updates. This distinct scenario should be acknowledged and addressed separately from the other data loss cases.
- Not enough free space on the Mac hard drive
- Incomplete macOS installation
- Mac takes forever to download the update
