os x yosmite shows this message at startup: To view this web content, you need to install the Java Runtime Environment.

The fix by Casey worked for me as well. Thank God! It was like a mosquito annoying me for the past couple of months.

Your method seemed to worked for many, however I clicked on your link but it showed me a white blank page.. If u know another way for me to get rid of this message please reply 😟

Clear Safari's cache, quit and relaunch it, and try the link again.

27" i7 iMac (Mid 2011) refurb, OS X Yo (10.10.1), Mavs, ML & SL, G4 450 MP w/10.5 & 9.2.2

For those who don't want or need Java installed, this worked for me. Open Terminal and run

$ launchctl list

to list the processes that launch automatically on startup. One of these is your problem – mine was an old Facebook browser plugin at com.facebook.videochat.{username}.updater, so I ran

$ launchctl remove com.facebook.videochat.{username}.updater

to disable it. Presto, no more Java popup, no download required,

It's not outmoded. It's up to other developers to make their apps/webpages compatible with SE 7 & 8, not Apple.

Try http://support.apple.com/kb/DL1572

For all, here's something from someone who knows the history, about Java and the JRE.

"Originally, Sun developed Java and supported it for all platforms except OS X. Since Sun did not develop and support a JRE for OS X, Apple stepped in and did the ports. At the time, it appeared that Java was going to be an important development language for client side applications as well as browser embedded applets. In fact, many applications were developed in Java as that was essentially the only language that allowed a single binary to run on multiple platforms. Apple also did not fully integrate the JRE, so on the Macintosh Java also had some rather serious performance issues.

"As Java faded as a development language for client applications and moved to being a server side language on Linux and BSD boxes, Apple pulled development resources from the OS X port. Later, even some the integration components allowing a more Mac like GUI were dropped. (Note that Java has been very successful for developing Android applications, where the Google JRE has extensive optimizations and a very good JIT. {Yes, I know about Dalvik - the point stands that a proper JRE can have very good performance even if Google uses a modified byte code.})

"With Oracle's purchase of Sun, Oracle decided to commit resources to the OS X port of the JRE and JDK. Apple no longer needs to do this port to maintain platform parity; hence Apple no longer supplies the JRE. However, it does still supply some of the integration components that Oracle uses in their ports of Java for OS X."

Try my way it works for everyone. Am sure of that ;-)

Well, why didn't you just say so!

Because I didn't have the info when I posted the original to reinstall SE 6.😎

Hello guys,

Apple original link is down. Here is a direct link to the file: support.apple.com/downloads/DL1572/en_US/JavaForOSX2014-001.dmg

I had this same issue ever since installing Yosemite. In addition, by iMac 27 has been restarting on its own accord, right in the middle of working, but mostly right after waking from sleep. After a couple of Genius calls, once to run disk utilities and another to run Apple Diagnostics, they finally provided this solution to install Java 6. This will get rid of the annoying pop-up, but i have doubts that it will resolve the restarts. Time will tell.

Worked perfectly. Thanks so much!

I had exactly the same "Java Runtime Environment" message at the beginning of the thread. I chatted on line with Apple and they checked a few Safari settings. An hour later the message re-appeared. I arranged a call (covered under Apple Care) the following day. I was told Java is a third party app, so Apple can't do anything and that I should contact Java. I'm not a Java expert (so I could be wrong) but it appears that the support is fee based and was reluctant to pay. In the end I deleted the Java plug in and installed Java for OS X 2014-001 listed above. Since then I haven't seen the Java Runtime Environment message. I've no idea if I did the right thing!

You did. The message popped up because you didn't have the Apple-supplied JRE component installted. The braindeads you talked to under AppleCare led you astray.👿
