I’ve already made the leap to using Yosemity on my MacBook Pro and so far all seems really stable and good. However I have a number of older version of Adobe applications on my machine like Photoshop CS4.
As soon as I tried to launch any of the Adobe applications after upgrading to Yosemity simply showed an error message sayin “In order to run Photoshop CS4 you need to install Java SE 6 Runtime”. After hunting around the Oracle site for the version of Java SE 6 for OSX I simply couldn’t find it.
I eventually found the correct download on the Apple site. And you can get it here.
