Java 1.6 on Mac OS X 10.5?

All we need is an easy explanation of the problem, so here it is.

I’m running OS X 10.5.8 on an Intel iMac and don’t have any immediate plans to upgrade to Snow Leopard. Am I able to upgrade Java to 1.6 somehow?

The release notes on Apple’s website for Java are kind of cryptic and aren’t clear what is necessary to upgrade Java to 1.6. (they mention that 1.6 only works on 64-bit Intel Macs… how do I know whether my Intel Mac is 64-bit or not?)

edit: java -version says I’m running J2SE 1.5.0_19 and I don’t understand how to upgrade from Java 1.5 to 1.6

update: I just downloaded the Java update from Apple, and I’m now running J2SE 1.5.0_20, not 1.6… argh.

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Grumble. There are multiple versions of Java that can coexist on Mac OSX, and you have to run Java Preferences (in /Applications/Utilities) to select the default version.

I love my iMac but sometimes Apple just doesn’t bother explaining some really simple stuff that would make life a lot easier.

So now I am running 1.6.0_15 successfully.

Method 2

For checking if you have a 32-bit or 64-bit Intel Mac, see Apples thorough KB article.

For updating Java, have you tried software update yet? You can also download Java SE 6 from Apple.

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
