java 7 11 okay for mountain lion??

HI

I am reading that there are problems in Java 7 for Mountain Lion.

I am not able to open any youtube or ASIC video clips. It says "blocked plug in" then has a black screen

Do I download Java JDK 7 then do I download the update JDK 7u11?

Will it then run on my mac and will I be in danger of security breaches eg trojans?

Seems like Apple are not supporting this and not offering any alternatives.

The salesman on line at Apple assured me that there would not be any problems or concerns in running Mountain Lion from 10.6.8 and I find youtube doesnt work

Thanks Trickietrev

iMac, OS X Mountain Lion (10.8.2), Youtube does not work on iMac

Welcome to the Apple Support Communities

Java 7 Update 11 fixes a dangerous bug, and that's why Apple has blocked all Java versions except Java 7 Update 11. If you need Java, download Java from Oracle website > http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads-1880261.h tml

Unless you are a developer, you have to download JRE. When you run Java, you are always in danger because it has got a lot of security problems, and that's why we recommend to not use it or use Java as less as possible to keep your computer safe

Hi

thanks for the info

I have downloaded the Java 7 Update 2 dmg os x 64 from the above site, unpacked it and tried to run a youtube clip and it is still saying blocked plug in
Do I have to restart the computer or allow somehow Java to open youtube files?

thanks Trev

You have to download Java 7 Update 11 and install it, so Java will work after installing this version

You dont use Java to watch youtube videos, you use Adobe flashplayer. Even though Java has been patched it is still advisable to disable it though your browser. Have you any apps that really needed it?

Thank you

I searched for Adobe Flash Player and the only thing on my Imac Flash Player install manager. I click this then it asks if I want to install

How can I tell if I am running Adobe Flash and what do I do to run the youtube clip to unblock log in?

thanks Trev

That should read if I click then Adobe Flash player install asks if i want to UNINSTALL not install indicating that I may already have it (which I assume I did) when I had OSX 10.5.8 until I upgraded all the way to Mountain Lion

Mac OS X x64

50.31 MB

jre-7u11-macosx-x64.dmg

This was the link that i used from your suggestion above it was 11 not 2

As per my posting it still did not run youtube clips and Killhippie suggests that it could be the flashplayer.

Perhaps flashplayer needs a new install or upgrade???

Have you tried to activate HTML5 mode in YouTube? > http://www.youtube.com/html5 It doesn't work for all videos, but it will be useful to get rid of Flash and use HTML5 with its pros

Hi

I tried to download the correct version of Adobe Flash Player but it downloads 47% and an error message says "cannot contact reliable source" and Google Chrome 64% downloads then says "download timeout"

Nothing is easy here

I disabled the firewall and it still errors above

Any suggestions?

Thanks Trev

What are you referring with "there is no link to Safari"? You just have to press the button to turn on the HTML5 mode and check if you can play videos
