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

Thank you! This error has been bugging me for a while and all the quick tricks did not work. Once I launched a terminal screen and pasted your commands, I saw an old Facebook.videochat file listed that had to be manually removed.

Perfect.

I had the same experience. I have to say the Java site was anything BUT easy to navigate, but I finally found the link for Java 8u25 and installed it. Same pop-up still happening. It is interesting to note that the Java being installed by the Apple update is Java 6, not 8. I wonder what will happen when I try to install the older version over the new one?

Thank you guys, it helped out Java for OS X 2014-001. Just installed it and annoiyng message disapeared after restart.

What honks me off is that Apple had to have known that this would happen for at least some users and made no effort to explain how to resolve it.

I don't like the idea of installing an outdated version of Java just to get rid of a pop-up window. I'm sure Apple will release a patch for this issue in the next update.

I've installed the update, but I regularly get the same error.

I'm using Firefox, if that makes any difference?

But I don't want Java... I never needed it.

What I want is to know what is triggering this popup! 😐

Frankly, I am not so sure. But something like this should have been a glaring issue in QC development of Yosemite prior to release. I am surprised that it could easily become an oversight of professional devlopers of Yosemite. I get this same repeat popup over and over as well. I will try the suggestion presented here as a resolution to this nagging problem.

Indeed I would like to know what is causing this.

Thanks Casey Rey!! I followed your instructions and that annoying Java error message is gone now.

Best regards,

Jack

Thanks Casey Rey, i had exactly the same issue on my mac pro. followed the instruction above, seems to be ok now.

I have a feeling Apple would prefer that Java was not on the machine. It can be a bit of a memory hog and a battery life killer..feel the heat on your 2008 17" macbook pro when running JRE for a long time in 10.5x..i think i burnt my leg once. But sometimes its a necessary evil to run these things. Support for Java on MacOs has been a bit 'at your own risk enter-here be dragons' for the last 2-3 years.

Just Sayin'

That does not convince me...

I get more and more annoyed by Apple, there's no support (at least no one from Apple here), they send hidden information everywhere without consent, forces us to install unnecessary software without explaining any reason...

I also bought this MacBook Pro with known fault on the screen (ghosting), but they sold it anyway with a "discount" and it was hard to return :/

Hope your hardware is really good because I'm most probably switching back to windows when this Macbook breaks...

P.S.: I won't install Java, unless Apple explains why! I prefer to continue as always using the laptop without Java running unnecessarily on the back

This is a user forum. Apple probably monitor it but they are not on here answering questions.

Not sure what you mean about the hidden information-i mean cheese how much info is 'gleaned' across the net and its nothing to do with the OS and don't get me started on the behaviour of some OSs!. You can set your machine to not give feedback to Apple.

Not sure what does not convince you in what Casey Rey said-its a fact there is a download. Download it don't download it ,what is you want Apple to explain? They made a decision not put JRE on OS X by default -i think there might be some licensing thing about it with Oracle going on. If you need it you need it if you don't you don't. Its like saying you wont install MS Office unless they explain why thats not on the machine by default.

Who sold you the machine with the faulty screen? Apple on line? The Apple store? An Apple Dealer? How long have you had it? If i buy a Ferrari with a dent in the door and i knew it had a dent in the door it would be funny to say 'when this Ferrari breaks i am switching back to Porsche because they don't have dents in the door'
