I own a really old version of Photoshop. After I upgraded to El Capitan when I attempt to launch Photoshop I get a dialog saying...
To open "Adobe Photoshop CS5.1.app" you need to install the legacy Java SE 6 runtime.
This is my current system Java version that came with the OS -->
java -showversion java version "1.8.0_65" Java(TM) SE Runtime Environment (build 1.8.0_65-b17) Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)
I downloaded the old, deprecated Java 6 DMG, but I haven't installed it yet.
My question is, will it replace the Apple's distributed Java?
And if so, is that likely to break applications that are expecting an up-to-date Java version?
Or will it just make the older JRE available as an alternative for applications that need it?
