Installing A Java JDK On Beta Versions Of OS X

Open the installation DMG and expand the package so we can edit objects inside the package, done with pkgutil:

pkgutil —expand “/Volumes/JDK 7 Update 67/JDK 7 Update 67.pkg” “/tmp/JDKTEMP.flat”

Next, we’re going to edit that Distribution file, which is what’s checking the OS version, using vi:

vi /tmp/JDKTEMP.flat/Dstribution

Then we’re going to look for the OS version (currently 10.7) in the pm_install section:

Edit OS version to 10.10

Then let’s save the file and then flatten the package, again using pkgutil:

pkgutil —flatten “/tmp/JDKNEW.flat” “/tmp/JDK7.pkg”

Finally fire up the package:

open /tmp/JDK7.pkg

And of course, finish running the installer. Good luck!
