Java not working

I have a:

Model Name: MacBook Pro

Model Identifier: MacBookPro5,5

Processor Name: Intel Core 2 Duo

Processor Speed: 2.26 GHz

Number of Processors: 1

Total Number of Cores: 2

L2 Cache: 3 MB

Memory: 8 GB

Bus Speed: 1.07 GHz


Running OS X 10.8.2


I was prompted to instal the new java update 7u11 and did - installation was a success.

BUT, I now don't have java plugins for safari or firefox. Can't run java on sites that I need.

Searching didn't help me with an easy to understand solution.

Any ideas?

MacBook Pro, OS X Mountain Lion (10.8.2)

leroydouglas,

after checking on version in teminal- it displays


java version "1.6.0_37"

Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)

Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)


same as husband's. Maybe mine was just disabled (which sounds like that could be a good thing security wise) and his has just not been disabled for whatever reason??

It will always say that if you previously installed the update to Java 6. When you install the JRE version of Java 7 from Oracle, it does not remove the Apple version and installs everything in a different place that the "java" command doesn't know about, so it continues to give you the Apple results.

Get this message but still nothing in cotrol panel and no plugins in browsers.

Unfortunately, I'm not currently in a position to install Java 7 with my current setup, but in going through some of the installer scripts, you should at least have these files in the all user (root level) Library (not your user or System Library) and they most should be dated Jan 13, 2013:


/Library/Application Support/Oracle/Java/

/Library/Internet Plug-Ins/JavaAppletPlugin.plugin

/Library/LaunchAgents/com.oracle.java.Java-Updater.plist

/Library/LaunchDaemons/com.oracle.java.Helper-Tool.plist

/Library/PreferencePanes/JavaControlPanel.prefPane

/Library/Preferences/com.oracle.java.Helper-Tool


I don't ususally do this because it's rarely necessary any more and wastes time, but have you repaired permissions on your boot volume using Disk Utility (found in /Applications/Utilities/)? The installer should tell you if it runs into any permission problems, but perhaps it didn't.

MadMacs0,

I looked at the library and it is there but see the image below - why the dash on the plugins folder. Looked at my husband's computer and his does not have the "dash" or colored folder.

So, it is a permissions problem. Wonder why that happend?


Plugins are a special kind of folder which would normally show up just as the other icons do if you had permission to see what was in it, but the red "x" means that you don't have read access. That's obviously why your browser can't load it and the web sites don't see it as being installed.


I could give you some Terminal commands to fix it if I knew what it was supposed to be, but I don't and you would probably prefer to try and use the Finder, so let's see if we can do it that way.


First of all, look at your husbands again and find out how his permissions are set. Highlight the plugin and select "Get Info" from the Finder's File menu (or type Command-I) and look at the very bottom of the window in the Sharing and Permissions section. Take note of the entries for the Owner, Group and "everybody", both the names and the Privileges.


Now go back to your computer and do the same with "Get Info."

Click on the padlock in the bottom right corner and enter your admin password when requested.

Now see if you can change those Privileges to match those on your husbands computer. If you aren't able to change them, we may have to resort to the Terminal app. In that case, let me know what your husband's computer settings were.
