Java 1 6 Mac 10 4 Ppca
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?
We don't have any change log information yet for version 1.8.11.12 of Java SE 8 Environment 8. Sometimes publishers take a little while to make this information available, so please check back in a few days to see if it has been updated.
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.

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.

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. Steam cracked free download.

1) Go to /Library/Internet Plug-Ins/
2) Remove from this directory everything listed as 'Java'. Yes, that includes Apple's own alias file 'JavaAppletPlugin.plugin'. I advise that you store these files somewhere, just in case you want to use them later for some odd purpose. I have them in a folder labeled 'Internet Plug-ins (disabled)' inside the Library folder.
3) QUIT and restart all your web browsers. Java now cannot run in them over the Internet, which is where Java is particularly dangerous.
There are other Java bits and pieces you could trash. But for the sake of simplicity and the ability to reinstate the Java Plug-In whenever you may want to actually use it on the Internet, I'd leave everything else in place.
NOTE: Running Java applications off the Internet is not typically a problem. Just be sure you run Java apps, off the Internet, from reliable developers. Trojan horse Java applications are possible. So avoid running mysterious Java apps you know nothing about. Check up on their reputation and verify they are NOT Trojans.
Why is Java over the Internet now so dangerous? Thank Oracle, who obtained Java when they bought Sun Microsystems. Oracle specifically BROKE the Java sandbox, allowing Java to interact directly with computer systems. This was the stupidest thing Oracle could do with Java.
