I’m only going back as for as 10.6 Snow Leopard as over 90% of users are using at least this version.
JAVA FOR MAC OS LION HOW TO
To help makes sense of this, I’ve listed the latest Mac OS X operating systems, including which versions of Java can run on it, and how to update it. Apple’s transitions coincides with the release of Java 7, which is currently the most recent major version of Java. Prior to Mac OS X 10.7 (Lion), Java was automatically included with the OS, and updates to it, were included in the regular OS updates. Most of this confusion comes from Apple’s transitioning away from being responsible for providing and distributing Java with its Operating System.
JAVA FOR MAC OS LION INSTALL
This has left a lot of computer users wondering whether they have Java on their computer, which version they might have, and which version should they have.įor Windows users, this is fairly straight forward, the best recommendation, is to install the most recent version of Java (currently Java 7, update 11) which can be downloaded from Oracle’s Java Downloads for all Operating Systems.įor users of Mac OS X, things get more confusing. A major security flaw was found in the Java browser plugin, and a fix has subsequently been released by Oracle. Java has been in the news a lot in the past few days, and not for good reasons. How does Java Security Flaw affect Desktop Applications
Test in terminal: % j8 % java -version java version "1.8.0_121" Java(TM) SE Runtime Environment (build 1.8.0_121-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode) % j9 % java -version java version "9" Java(TM) SE Runtime Environment (build 9+181) Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)ĮDIT: Update for Java 10 export JAVA_HOME10=`/usr/libexec/java_home -version 10` alias j10='export JAVA_HOME=$JAVA_HOME10 export PATH=$JAVA_HOME/bin:$PATH'ĮDIT: Update for Java 11 export JAVA_HOME11=`/usr/libexec/java_home -version 11` alias j11='export JAVA_HOME=$JAVA_HOME11 export PATH=$JAVA_HOME/bin:$PATH' Top 3 video Explaining java - Where is JAVA_HOME on macOS Mojave (10.14) to Lion (10.This is a follow up to another Blog post I made: Some additional alias to switch between the different versions: alias j8='export JAVA_HOME=$JAVA_HOME8 export PATH=$JAVA_HOME/bin:$PATH' alias j9='export JAVA_HOME=$JAVA_HOME9 export PATH=$JAVA_HOME/bin:$PATH'
Set active Java: export JAVA_HOME=$JAVA_HOME8 export PATH=$JAVA_HOME/bin:$PATH Note, that for the latest version it is 9 and not 1.9. bash_profile: export JAVA_HOME8=`/usr/libexec/java_home -version 1.8` export JAVA_HOME9=`/usr/libexec/java_home -version 9` Note, updating this to 1.8 works just fine.
export JAVA_HOME=`/usr/libexec/java_home -v 1.7` Update: Understanding Java From Command Line on OSX has a better explanation on how this works. usr/libexec/java_home still insists on 1.6. The only fix that actually works for me is setting JAVA_HOME manually: export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_06.jdk/Contents/Home/Īt least this way when run from the command line it will use 1.7. It does list the 1.7 JVM but I can toggle/untoggle & drag and drop all I want there without actually changing the output of /usr/libexec/java_home.Įven after installing 1.7.0 u6 from Oracle on Lion and setting it as the default in the preferences, it still returned the apple 1.6 java home. That's what the Java Preferences app is for, which in my case seems broken and doesn't actually change the JVM correctly. It outputs the currently configured JAVA_HOME and doesn't actually change it. usr/libexec/java_home is not a directory but an executable.
