I purchase a refurbished 27 inch iMac 3.1 GHz Intel Core i5 with Mac OS 10.7.3 installed in September 2012. I got the free upgrade to Mountain Lion OS 10.8.2 shortly afterwards. In December 2012, the computer started crashing occasionally while watching videos on the web. It deteriorated to the point that the iMac would crash while it was on, but not being used at the moment of the crash. After calling Apple support, they suggested I take the machine into an Apple store to the Genius bar to have the hardware checked and tested.
I took it into the Apple store, and several diagnostic tests were run on the hardware of the computer. The technician told me the good new was nothing was wrong with the hardware. The bad news was the technician believed it was a software issue. He asked how I got all my data and applications on the computer. I told him I had used migration assistant with the back-up drive of my Mac Book Pro with Mac OS 10.5.8. He told me to never use Migration Assisitant or Transfer to get data or applications from an old computer to a new computer.
Why is this even suggested in the set up process by Apple if it can cause issues? I have owned various Apple computers since my first Mac SE in 1984. I have always used Migration Assistant to upgrade from an old computer, and never had any problems. Thanks for the heads up, Apple!
AS suggested, I cleaned my iMac hard drive completely with Disk utilities. I originally had partitioned my 1 TB drive to have a boot up for the existing OS 10.7 Lion, and another partition for the new Mac OS 10.8 Mountain Lion. This was suggested by Apple Support. I wanted to be sure I liked the new Mountain Lion, and that all my applications would continue to work. I was unable to erase the partitions before reinstalling the OS software from the Recoverry disk. I wanted to reinstall the OS and my data on the Imac the way it was delivered (1 single TB partition) when purchased. With the help of Apple Support, I was able to erase the partions, but had to reinstall the OS from internet recovery. The internet recovery process installed the original OS 10 .7. I decided to install Mountain Lion 10.8.2 before getting all my data and applications copied to the iMac. I used my Mountain Lion Flash drive install disk to do the upgrade.
Than as suggested by the Genius bar Technician, I created 2 new folders on my desktop. One folder was to copy applications from my back up drive, and the other was to copy all my data (music, pictures, doccuments etc.). The technician told me this could eliminate problems by moving everything by hand not any application to empty desktop folders first before putting items in their correct folder on the iMac hard drive.
After finishing copying all the items from back up, I moved the applications from the desktop folder (named applications from BU) into the hard drive application folder. I tested all the applications to be sure thay would open. Some had multiple user issues, and Photoshop cs4 wouldn't open or reinstall from the original downloaded .dmg. I contacted Adobe support to see what to do about Photoshop.
I was getting ready to follow Adobe's fix instructions, and the iMac crashed again just as before. The Genius Bar technician said a "kernal" message was what the error display was called. After starting the computer, I took a "picture" of the crash report before sending it to Apple. All my data (music, pictures, doccuments etc.) I copied from my back up drive remains in a folder (Doccuments From BU) on my desktop. I have not even bothered to boot up the iMac the last few days. I'm hoping it doesn't crash before I post this message.
Below is a list of the applications from my back up drive that I have moved from the desktop folder to the Application folder:
Adobe Bridge CS4 (Version 18.104.22.1684)
Adobe CS 4 (No Version, won't open, reinstall of software failed.)
Disk Warrior (Version 4.4)
Jawbone Updater (No Version, need to plug in Bluetooth speaker to get update for speaker software)
Microsoft Office 2011 (Can't open,need to update multple users permission)
Quicken 2007_Lion Version (Version 16.1.2)
Turbo Tax (for 2006 - 2011)
To say I am tired of investing all my time and energy doing all of the above work on a computer that I bought only 4 months ago is an understatement!!! I do not enjoy spending what little free time I have trouble shooting an expensive recently puchased item that is supposed to make my life easier.
As I stated earlier, I have only owned Apple Computers since 1984. I supported all their products based on their innovative, trouble free operating systems, and the reliability and stability of their hardware. This frustrating experience is changing my opinion. I'm wondering if the company should consider changing their name to another fruit ... Lemon. Maybe, the operating system should be called Lemon and Mountain Lemon.
Any help or suggestions to fix this "crash" problem would be greatly appreciated!
