Well, not necessarily. Whether it's a problem really depends on how Java programs decide which version to use, or really if they get the choice at all. If they do, the code should be fairly simple and all the user would have to do is make sure that they have installed all the updates from Apple. ------ And actually after writing this I thought "why not try it out on Java Web Start?" and so discovered that it's quite easy to require Java 6. I simply opened "freenet.jnlp" in a text editor and changed the line <j2se version="1.5.0+" /> to <j2se version="1.7.0+" /> In an attempt to then run the installer, I received this error: "The application has requested a version of JRE (version 1.7.0+) that is not installed." ------ Now that that's out of the way, we'll still have an issue if we don't tell Mac users ahead of time that if they aren't using 10.6 or greater, the'll need to (1) at least be using 10.5 and (2) actually install all of official software updates from Apple.
