How do I use JDK 7 on Mac OSX?

Solution 1:

This is how I got 1.7 to work with Eclipse. I hope it helps.

  1. I Downloaded the latest OpenJDK 1.7 universal (32/64 bits) JDK from Mac OS/X branch from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
  2. copied the jdk to /Library/Java/JavaVirtualMachines/ next to the default 1.6.0 one
  3. In Eclipse > Preferences > Java > Installed JREs you add a new one, of type MacOS X VM, and set the home as /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home and name Java SE 7 (OpenJDK)
  4. Click Finish
  5. Set the added JRE as default

that should be it :)

Solution 2:

Oracle has released JDK 7 for OS X.
