Use Software Update
- Choose System Preferences from the Apple menu , then click Software Update to check for updates.
- If any updates are available, click the Update Now button to install them. Or click “More info” to see details about each update and select specific updates to install. You might be asked to enter your administrator password.
- When Software Update says that your Mac is up to date, the installed version of macOS and all of its apps are also up to date. That includes Safari, Music, Photos, Books, Messages, Mail, Calendar, and FaceTime.
- To automatically install future updates, including for apps that you got from the App Store, select “Automatically keep my Mac up to date.” Your Mac will notify you when updates require it to restart, so you can always choose to install those later.

Mac Update Java Version
- If you have Java (JRE) installed on your Mac, then you have Java Web Start (JWS). The question is does the Java application you normally run in Safari use JWS technology? JWS launches automatically if you download a Java app that uses it (usually in the form of a.jnlp file).
- Note that macOS Big Sur changed the behaviour of the javahome command. Noe, if if the JAVAHOME environment variable is already set to a valid JDK that is all it will return, it will ignore the -v parameter. If JAVAHOME is set to an invalid folder, the javahome command won't work at all.
