How can I reinstall JAVA on Mountain Lion?

The last Java Update screwed up Java on Mountain Lion. Thanks a lot, Apple. This is where blinking/flashing images etc etc start, and it also affects the three-finger word-look-up gesture. I compared my mac running Facebook in Safari with one in an AppleStore and the one in the shop renders the Java stuff flawlessly -- no blinking or flashing graphics, and the three-finger tap gesture works perfectly. Both macs were running the same version of Java, OS X and Safari.
If I turn off Javascript and Java (in Safari) I don't get the flashing images and three-finger-tap works.
So my question is (after reading similar threads of the same topic): IS there any one-click solution to this -- can I reinstall Java, or do I have to re-install Mountain Lion... JUST to get Java working again??!?
And per the above.. why ISN'T there a standalone Java re-installer for OS X? How difficult could it be??

I just found the solution, thanks to the "MORE LIKE THIS" links:

That's where you can download the standalone installer!! I did it, ran it, and it works. Solved all the problems I've been having.
Thing is.... why is it hidden???

  • HT4718 How can i reinstall OS X Mountain Lion on my computer after my hard drive failed and i had a new one installed?

    I paid for Mountain Lion about 2 months ago and my Hard drive just crashed.  Is there a way i can reinstall Mountain lion without having to pay again?

    What OS did it ship with? If it was Lion, then you can use Internet Recovery to install on the new drive. IR will install the original shipping OS. You can then log into the App store and upgrade to Mountain Lion.
    If it came with Snow Leopard, you will need to install Snow Leopard from your install DVD, then upgrade to Mountain Lion.

  • Can i reinstall OS X Mountain Lion from scratch from a Time Machine Backup

    Can i reinstall OS X Mountain Lion from scratch from a Time Machine Backup
    Asking because i'm a new mac user having used windows since 3.11, wanting to know if the Time Machine bacup was enough or will i need to make a seperate OS install disk or usb drive ???
    thanx in advance guys

    Lizardcarter's instructions are correct, you can (and possibly should) consider a second external HD to create a bootable clone. Redundancy in backups is a very good thing because backup can fail too. A bootable clone is an external HD that has a mirror of your internal HD so if the internal HD does crash you can boot from the clone, something that cannot be done from TM. This means you will be down for minutes and can resume work until you have had the internal HD replaced. Never use an external HD for both TM and a bootable clone, each should have it's own EHD. The reason being is if the EHD crashes you have lost ALL of your backup and are dead, don't laugh it happens! To create a bootable clone get either SuperDuper or Carbon Copy Cloner (both about $30) and you're pretty set. Many people on these forums (including myself) use that strategy and yes I have had a backup fail.

  • How do you reinstall OS X Mountain Lion?

    I have had a problem and I was wondering how you take off Mountain lion and reinstall it onto the OS?

    restart your computer while pressing down both the command and r keys at the same time....
    once you see the apple logo, release the keys and you'll get into the disk utility menu....reinstall from there...
    good luck...
    another way of doing it is to redownload mountain lion and create a install usb thumb drive....
    read here for instructions on how to create one....that way, you don't have to redownload it everytime you need to reinstall...

  • I installed Maverick It turns off for no reasons, makes Safari a miserable experience, and more.  How can I get back to Mountain Lion?

    Maverick is a mess, well up to MS at its best.  i installed it over Mountain Lion on a base Air that initially came with Lion.  The worst is when the screen suddenly goes blank.  After a few times, i found tha tsimpy pressing the power button brought up the welcome screen which - after the password - took me back to where I was with no loss, bu tthe first time was horrible.  Then WORD for MAC started behaving strangely, with normal operations simply not working - shading to copy or cut out, for instance.  Click again and again, no shading - then suddenly it workds!  Safari has similar issues.  So too with other software downladed earlier.  simply nothing works as well as all did under Mountain Lion.
    So, I want to deep six Maverick and get back to Mountain Lion.  I assume that if I use CONTROL R I will simply reload Maverick.  Can I download Mountain Lion from the App Store and then ???  All the copying and such - a half day lost.  Is there are easier way? 
    <Edited by Host>

    It's Command-R, not Control-R. You won't lose your files or settings if you reinstall 10.9 this way. Why don't you give that a go before reverting to 10.8.

    If your system's not compatible with 10.8 and has at least a Core 2 Duo(not Core Duo) CPU, phone the online Apple Store and order a download code for 10.7.

  • How can i re-download osx mountain lion ?

    I buy it once and i dond´t want to buy it twice, but i can't get access to my account and download it again.

    Taktak59,
    if you’ve bought it already, then you need to connect to the Mac App Store using the same Apple ID as you’d used when you first bought it. You should then be able to redownload it by holding down the Option key while clicking on Purchases, and then Option-click on OS X Mountain Lion from the list of purchased apps.

  • How can I reinstall Quicktime X in Lion?

    OK, to make a long story short, I had a new audio problem in the Quicktime X Player after installing Lion (that I oddly enough didn't have in QuickLook, QuickTime Player 7, or VLC), and I assumed a reinstallation was in order (because I also assumed I had mucked something up by trashing some "orphan" files with TrashMe). I thought I couldn't reinstall Quicktime X Player from the Lion installation package without another two-hour-plus download, so I reinstalled it from my Snow Leopard installation disc using Pacifist naively assuming Software Update would bring me back up to date. Well, that didn't work, and now I have a copy of Quicktime X Player that won't run on Lion. I tried redownloading the Lion installation package and reinstalling the correct version of Quicktime X Player with Pacifist again, but Pacifist can't handle Lion's installation package (it crashes when you try to install or extract anything). Well, I don't have a backup, so that's not an option, and I don't have any external devices large enough to back up my files and applications, so a clean install with Lion Recovery isn't an attractive option either. Is there any way I can install Quicktime X Player on my computer again without wipping my hard drive? Is it safe to let the original Lion intallation process I downloaded from the app store run again? Will it simply replace the relevant existing files no-harm-no-foul, or will I just further muck things up?

    Yeah, I don't feel like taking any more risks. Obviously, I don't know what I'm doing.
    On the support.apple.com article on Lion Recovery, it says "These steps will erase and reformat the storage device. This article will instruct you on setting up the storage device to use the GUID partition scheme and the Mac OS Extended (Journaled) format, which are required to install Lion and an Internet Restore partition on your external storage device. You should back up any important files that are on the device to a different drive."
    I understand the necessity of a backup option, but I need to replace a failed superdrive, and that gets budget priority over reinstalling Quicktime. (My MacBook Pro, bought in Japan, shipped with a defective superdrive that could read but not burn - it could never burn and was just plain broken. I wasn't willing to part from my laptop long enough to get it replaced while it was still under warranty, let alone deal with Japanese Apple support, but now I have something that I need to burn by the end of the week.)

  • How can I tell if my mountain lion installation failed?

    My 2007 MBP has been updating to 10.8 from 10.7 now for about 3 hours. I see an Apple logo on the main screen, the keyboard is lit, and that's it. If I put my ear up to the machine around where the HD is, I hear noise, but no seeking (not that I really ever heard any from this HD).
    Anyone know how long this can take? Should I "pull the plug" and see what happens? I have a backup I can restore from (2 actually).
    TIA

    Make sure you blow out the dust in your machine.
    Try reseating the video card (remove and reinsert).
    What kind of monitor and what kind of video card are you using?

  • How can Mail of OS X Mountain Lion read Chinese Characters?

    Mail cannot read Chinese characters. Message looks like a series of "??????". However, Safari can read Chinese characters. What setting can make Mail read Chinese Characters?

    Normally that indicates an encoding glitch, where the email headers are not telling Mail the right encoding to use.  The first thing to try is Message > Text Encoding and see if UTF-8 or one of the various Chinese encodings give the right display.
    Also go to View > Message > Raw Source and tell us what you see in the headers that say "charset=  ".
