Faulty Video Software Update...?

[fab5freddy]

I am getting really bad glitches and flashes on any flash video
after i did the software update recently......

Has anyone else had this problem and what can you do to fix the problem ?

thanks!

That update was pulled by Apple, which is getting quite common nowadays.
They will probably issue v1.1 update in a week or two.

Anyway, if you want to fix it now, you can replace with the NVIDIA kexts from 10.5.6 update. Extract them with pacifist from the 10.5.6 update, replace the ones you currently have and repair permissions.

How I went about reverting this update...

As well as a full drive image, you can also pull the mentioned kernel extensions from a time machine backup (from a date previous to when you did the update.)

(The following should be done AT YOUR OWN RISK...)

using 'terminal' cd into the directory on your backup containing the old extensions. For example:

cd /Volumes/TMDrive/Backups.backupdb/My_MBP/2008-12-28-183230/Macintosh\ HD/System/Library/Extensions

Then, for each of the listed extensions, execute a line similar to:

cp -pRv EXTENSION_NAME /System/Library/Extensions/

(cp -pRv: copy, preserve file attributes, recurse, verbose)

Run that command once for each extension name listed in the linked thread, and replace "EXTENSION_NAME" with the extension name.

DISCLAIMER: If these instructions are confusing or scary, please don't follow them. It would be trivial to screw up your OS install messing with kernel extensions!
