How to remove 10.6.8 system update?

Question

After Installing 10.6.8 system update, my mac book pro panics randomly. I really really really want to remove the system update. What is the proper procedure for removing a system update? This is beyond annoying!!!!!!Apple is irresponsible to push out junky system update out just like this without testing!!!!The output is:Interval Since Last Panic Report:  3347 secPanics Since Last Report:          4Anonymous UUID:                    2E02BFAF-C79C-4D75-935C-D9852491A2B5Fri Jul  1 15:04:01 2011panic(cpu 0 caller 0x5054a6): "OSCollection::_RESERVEDOSCollection6 called."@/SourceCache/xnu/xnu-1504.15.3/libkern/c++/OSMetaClass.cpp:906Backtrace (CPU 0), Frame : Return Address (4 potential args on stack)0x7c5b3698 : 0x21b837 (0x5dd7fc 0x7c5b36cc 0x223ce1 0x0)0x7c5b36e8 : 0x5054a6 (0x5de36c 0x5def46 0x5def46 0x6)0x7c5b3708 : 0x50834e (0x85f858 0x6 0x7c5b3748 0x507001)0x7c5b3728 : 0x99a59b (0xd91ec00 0x0 0x24 0xd929ec0)0x7c5b3788 : 0x99a9c2 (0xd91ef00 0xd929ec0 0x2 0x99a9e6)0x7c5b37c8 : 0x966720 (0xd91ef00 0xd923300 0x7c5b37f8 0x0)0x7c5b3818 : 0x543f60 (0xd91ef00 0xd923300 0x1 0x506b76)0x7c5b3878 : 0x542137 (0xd923300 0xd91ef00 0xd9245a0 0xd924640)0x7c5b3928 : 0x5426e9 (0xd923300 0xd929d80 0x0 0xffffffff)0x7c5b3978 : 0x5439b9 (0xd923300 0x0 0x7c5b39a8 0xd924800)0x7c5b39b8 : 0x542d91 (0xd923300 0x0 0x7c5b39e8 0x85f8f8)0x7c5b39f8 : 0x963441 (0xd923300 0x0 0xd548cc0 0xd9248c0)0x7c5b3a18 : 0x95be86 (0xd923300 0xd8a2000 0x0 0x7c5b3a78)0x7c5b3a58 : 0x995d8a (0xd8a2000 0xd8a2d00 0x0 0xd912740)0x7c5b3ae8 : 0x543f60 (0xd8a2000 0xd8a2d00 0x1 0x506b76)0x7c5b3b48 : 0x542137 (0xd8a2d00 0xd8a2000 0xd9126a0 0xd9129c0)0x7c5b3bf8 : 0x5426e9 (0xd8a2d00 0xd8fb8c0 0x0 0xffffffff)0x7c5b3c48 : 0x5439b9 (0xd8a2d00 0x2 0x7c5b3c88 0x507001)0x7c5b3c88 : 0x542d91 (0xd8a2d00 0x2 0x1 0x1)0x7c5b3cc8 : 0x9340d0 (0xd8a2d00 0x2 0x7c5b3cf8 0x506785)0x7c5b3cf8 : 0x938246 (0xd8a2f00 0xd8a2f00 0xd8a2d00 0x0)0x7c5b3d78 : 0x153a184 (0xd8a2f00 0xd8eb480 0x1 0x1)0x7c5b3d98 : 0x153ae4b (0xd8eb480 0x1 0x1 0x0)0x7c5b3de8 : 0x153a6af (0xd8eb480 0x955778 0xd4efdc0 0x10001)0x7c5b3e18 : 0x543f60 (0xd8eb480 0xd8a2f00 0x1 0x506b76)0x7c5b3e78 : 0x542137 (0xd8a2f00 0xd8eb480 0xd89e760 0xd8d8e40)0x7c5b3f28 : 0x5426e9 (0xd8a2f00 0xd8ace40 0x0 0xffffffff)0x7c5b3f78 : 0x5443d5 (0xd8a2f00 0x0 0x7c5b3fac 0x1)0x7c5b3fc8 : 0x2a179c (0xd884930 0x0 0x2a17ab 0xd722b7c)      Kernel Extensions in backtrace (with dependencies):         com.Mouse.driver.MouseSetting(1.0.1)@0x999000-&gt;0x9a0fff            dependency: com.apple.iokit.IOUSBFamily(4.2.4)@0x920000            dependency: com.apple.iokit.IOUSBHIDDriver(4.2.0)@0x992000            dependency: com.apple.iokit.IOHIDFamily(1.6.6)@0x956000            dependency: com.apple.iokit.IOPCIFamily(2.6.5)@0x909000         com.apple.iokit.IOUSBHIDDriver(4.2.0)@0x992000-&gt;0x998fff            dependency: com.apple.iokit.IOHIDFamily(1.6.6)@0x956000            dependency: com.apple.iokit.IOUSBFamily(4.2.4)@0x920000         com.apple.driver.AppleUSBComposite(3.9.0)@0x1539000-&gt;0x153cfff            dependency: com.apple.iokit.IOUSBFamily(4.2.4)@0x920000         com.apple.iokit.IOUSBFamily(4.2.4)@0x920000-&gt;0x955fff            dependency: com.apple.iokit.IOPCIFamily(2.6.5)@0x909000         com.apple.iokit.IOHIDFamily(1.6.6)@0x956000-&gt;0x991fffBSD process name corresponding to current thread: kernel_taskMac OS version:Not yet setKernel version:Darwin Kernel Version 10.8.0: Tue Jun  7 16:33:36 PDT 2011;

One or both of these extensions may be incompatible.com.Mouse.driver.MouseSetting          1.0.1 - last loaded 1268654864com.Seagate.driver.PowSecDriver          4.4.10The first one is where the panic occurred, so you might try removing whatever the mouse is and its driver to see if the problem is resolved. Alternatively, boot into Safe Mode and see if the panics stop.Apple claims no responsibility for incompatible third-party hardware or software.You can reinstall OS X to return to an earlier version:Reinstall OS X without erasing the driveDo the following:1. Repair the Hard Drive and PermissionsBoot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.&#x27;s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don&#x27;t have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.2. Reinstall Snow LeopardIf the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.Download the appropriate Combo Updater to return to the version you desire from support.apple.com/downloads/.
