This may be a longshot, but I NEED to get Java JRE 7 running on Mac 10.6. The official documentation states

Mac OS X System Requirements

  • Intel-based Mac running Mac OS X 10.7.3 (Lion) or later.
  • Administrator privileges for installation 64-bit browser

Is there any way I can trick the java JRE 7 into installing itself on OSX 10.6? Is there some community version of a JRE 7?

  • I highly recommend not doing that because you end up getting some strange and unpredictable behavior for you applications and you end up spending a lot of time trying understand and debug. why don't you just upgrade ? – grepit Feb 27 '13 at 19:35
  • user717630 I would if they were my own machines, but my client said there is a 0% chance of them upgrading. – Daisetsu Feb 27 '13 at 19:40
  • To be clear - this is ***NOT*** a dupe of this question http://stackoverflow.com/questions/14102761, which this post has been flagged as. They refer to different OSX versions. – Richard J. Ross III Mar 01 '13 at 17:21

It can be done, just follow what this answer suggests. I successfully installed JDK 7 update 11 a couple of weeks ago. However I have only used it for some development, and am not sure if it runs e.g. Swing apps without issues.

No.

Easiest is most likely to install virtual box and run Ubuntu inside.

EDIT: The comments indicate that this is not for hobby use but a client. I would personally never base a commercial solution on unsupported software, and I hope it has been made absolutely clear to the client what this can result in.

A better solution might be recompiling your Java program for Java 6 (use the Eclipse compiler with -source and -target) and run it under Java 6. If you cannot do this - as you said NEED - then open a new question asking how to backport that facility to Java 6.

  • Sorry, but "No." is just clearly not true. See my comment on the question. – zagyi Feb 27 '13 at 19:55
  • @zagyi being able to _install_ a program under an unsupported operating system does not mean that it _runs_ correctly which I - and most likely also the OP - would consider a requirement for being able to say yes instead of no. Especially for such a complex system as a modern JVM. – Thorbjørn Ravn Andersen Feb 27 '13 at 20:01
  • You are probably right, however I answered to the question. "Is there any way I can trick the java JRE 7 into installing itself on OSX 10.6?". I guess the OP also realizes what it means to install a JRE in an unsupported platform, but if he doesn't have any other option, he can at least give it a try. – zagyi Feb 27 '13 at 20:29
  • If you answer, write a proper answer instead of a comment saying I am wrong. This allows the OP to select it as the most helpful answer and does not pollute other answers with non-constructive comments. – Thorbjørn Ravn Andersen Feb 27 '13 at 20:32
  • Sorry, you are right. I just thought my post doesn't deserve an answer being barely more than a reference to another thread. I'll add an answer now which you can downvote :), and will remove my comments from here if I can. – zagyi Feb 27 '13 at 21:09
  • Technically you are right Thorbjørn Ravn Andersen. On the other hand zagyi did present a reasonable solution, which actually solved the problem (JRE 7 installed via Pacifist). upvotes for both of you, but zagyi delivered. – Daisetsu Feb 27 '13 at 21:18
  • @zagyi I am not interested in down voting your answer, and haven't. That does not mean I agree with you, though, but it is two different directions. – Thorbjørn Ravn Andersen Feb 27 '13 at 23:04
  • @Daisetsu your recent comments indicate that this is not for hobby use but a client. I would personally never base a commercial solution on unsupported software, and I hope you have made it absolutely clear to your client what this can result in. Also software exists to retrofit a java program to an earlier version of java. – Thorbjørn Ravn Andersen Feb 27 '13 at 23:09
