Upgrading to Mac OS X, version 10.10, “Yosemite”

Since teachers of students in Grades 6–12 and students in Grades 9–12 are “administrators” of the MacBook Air laptop that has been issued to them, these users have the ability to open the App Store application and upgrade to the latest operating system. The new version of Mac OS X (pronounced Mac O S ten) is version 10.10 (ten point ten) and is referred to by Apple as “Yosemite,” named after the National Park known for its spectacular granite cliffs and wilderness areas.

Yosemite (the operating system) is the eleventh release of Mac OS X (the first version was 10.0) and represents a major overhaul of the look and feel of the software. Many of the features of the Mac operating system are designed to interact with and complement iOS 8, the new operating system that runs the iPhone, iPad, and iPod touch.

While there is currently no requirement to upgrade to Mac OS X Yosemite, many users may wish to do so to take advantage of the new features. So far, the operating system has been very stable and works well on Barrington 220’s network. The only application that requires a bit of additional attention is GroupWise, our email and calendar system.

Upon launching GroupWise in Mac OS X Yosemite, you will see a message asking you to install an earlier version of Java. Below you will find a set of directions to help you install the software to allow GroupWise to run in Yosemite.

1. Launch the GroupWise app.

2. Click More Info...

3. Click Download and wait for the software installer to download.

4. Look in the Downloads folder for the file JavaForOSX2014-001.dmg and double-click the file to open it.

5. Double-click JavaForOSX.pkg to open it.

6. Click Continue (three times):

7. Click Agree.

8. Click Install.

9. Type your computer’s password. Click Install Software.

10. After installation, click Close.


Because these instructions downgrade the Java version, the Mac will ask you to upgrade Java within a day or two. Make sure to resist the urge to upgrade since it will cause GroupWise to no longer work. When you see this screen, click Skip This Version.


  1. MANY THANKS to Vanessa Fennig at BHS for spotting a correction in Step 2!

  2. Heading: The Alternative To A Mac Upgrade
    When you are using a Mac sometimes you can notice that over time your computer will be
    slower with a bit more lag than you are used to and that's because sometimes information gets
    truly clogged up and starts overlapping and really destroying the functions that should preform
    normally. You do not need to upgrade your Mac anymore not with Detox your Mac. What this
    program does is it truly helps to clean out everything in your Mac and make it function better
    and faster than it has in a long time. Sometimes even restoring the factory quickly you had when
    you bought the computer to begin with. When you use a computer it becomes absolutely filled
    up with useless files and copies of files which you thought you might have gotten rid of but the
    fact of the matter is that everything is stored on a computer until you can really get in there and
    clean it with a product such as Detox my Mac simply because it gets down deep into the
    computer to places that a normal Mac user wouldn't even go to look for things. Understanding
    full well that Mac computer are not cheap means that instead of getting an even more expensive
    upgrade you can actually use this product to help clean out everything that need to be cleaned
    out and get your computer up and running at peak performance.
    Within just a few seconds after starting the program you can have it go through hundreds of
    thousands of files getting rid of everything that is useless. Having a hard drive full of useless
    information really does make things so much harder on the computer itself and can be a true
    frustration to someone who really needs to just get the job done on the computer but instead
    they are having to wait longer and longer periods of time for loads and downloads or even for
    the initial startup of the computer before they can get anything done. That's the great thing
    about Detox my Mac is that it takes your computer and goes through file by file and everything
    that is useless it will get rid of it and help restore the Mac back to a point where you can actually
    get what you need to get done without issues or waiting or even the dreaded crashing. It's not
    the standard files it goes through it also goes through the logs which can totally slow down the
    whole function of the computer even though they aren't needed except for in development
    states that doesn't seem to matter, this program will truly get in there and with an intelligent
    nature it will get rid of all the log files. It will also go through the language files and get rid of all
    the unused language files as well.
    This is very important because it can take a huge portion of your hard drive just storing unused
    languages and this gets rid of all of it. You will be getting with the Detox my Mac program the
    most innovative and powerful product in the world when it comes to this kind of software. You
    get absolutely instant access to the program with a very quick download. You will get totally free
    upgrades for life with this program as well which means that you will never again pay for another
    update like with most software you will pay a one time fee of $37.95 and you will have
    everything that you need at your finger tips. You will have a safe and trusted program which is
    the industry leader in it's field, and that means that you get 24 hour a day 7 day a week support
    if any issue comes up. You also get a 60 day money back guarantee which means that if for any
    reason you do not like what you've gotten or it didn't work as well as you'd expected in 2 months

    then you can return it for the full price you paid for it and not a cent less. Detox my Mac is truly
    the best program you can get to help get your Mac back in factory fastness and standard.
