Q: Installation and Start Up Problems

I want to start off by saying that I am new to Mac and am still learning my way around it. I have an iMac5,2 (Mac-F4218C8). I got it used and it was supposed to come with Snow Leopard installed but didn't. I recieved an installation disk and installed fine the first time, however, after getting updates it froze. I had to force restart it and now when it boots up, I get a screen that says;

 

panic(cpu 0 caller 0x2acca8a): "Version mis-match between Kernel (23) and CPU PM (24)"@/SourceCache/xnu/xnu-1504.15.3/osfmk/i386/pmCPU.c:771

Debugger called: <panic>

Backtrace (CPU 0), Frame : Return Address (4 potential args on stack)

 

followed by 14 lines of numbers, then;

 

         Kernel Extensions in backtrace (with dependencies):

               sk.triaxis.kext.SleepEnabler(1.0.0)@0x2e9c2000->0x2e9c3fff

 

BSD process name corresponding to current thread: Unknown

 

Mac OS version:

Not yet set

 

Kernel version:

Darwin Kernel Version 10.8.0: with a date and time and something I can't read, it's behind a screen that says to restart the computer

System model name: iMac5,2 (Mac-F4218EC8)

 

When I restart, it just keeps going to this screen. I have tried reinstalling with the disc but it shows the Apple logo and the spinning wheel for a while then, a lot of code scrolls down the screen too quickly to read, and restarts, sending me back to that screen. I have tried booting into Safe Mode but it doesn't work. I have tried resetting PRAM and the one that starts with N (can't remember what it''s called, sorry) and nothing. I have also tried installing from a bootable USB drive and the computer recognizes it when I start up holding option, but it shows me a circle with a line through it and the spinning wheel and just stays on that untill I force shut down. I have also tried holding D when I start up to get into AHT, but that doesn't work either. I am at a total loss as to what to try next. Please help.

Thanks


iMac, Mac OS X (10.6)

    If you can't boot with the SL install disc, then a trip to an Apple repair station is in order.

    The first thing you should do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. How you do that depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.

    1. You don't own another Mac.

    If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc, which you can get from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. I suggest you install as much memory as it can take, according to the technical specifications.

    If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. If you don't have the media, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.

    To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.

    If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.

    2. You do own another Mac.

    If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to create a bootable USB device and boot the new Mac from it by holding down the C key at the startup chime. You will need the Apple ID and password that you used to upgrade. Note that if your other Mac was never upgraded in the App Store, you can't use this method.

    Once booted from the disc, the USB device, or Internet Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive, which is what you should do.

    After partitioning, quit Disk Utility and run the OS X Installer. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.

    You should then run Software Update and install all available system updates from Apple. If you want to upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.

    If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Apple customer service has sometimes issued redemption codes for these apps to second owners who asked.

    If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to  authorize it under your ID. In that case, contact iTunes Support.
