Snow Leopard Update Inverts Mouse Y Axis

Post by robert-tmw »

Strange.... I just allowed a fresh install of Snow Leopard to update to the latest updates (for Leopard), and when the machine rebooted the mouse's Y-axis is inverted. I'm not talking about scrolling (which no longer works) but how the mouse cursor moves on-screen. :?

Any ideas?

TIA,
Robert

Post the guests log file ( as an attachment ). Right click on the guest in the Main Manager then click show log. Save and post as an attachment. Compress if it is too large to post.

[SOLVED] Re: Snow Leopard Update Inverts Mouse Y Axis

Hi Perry,

Thank you for responding! :)

I found the answer last night. The update installs a bad IOUSBFamily.kext and bad IOUSBMassStorageClass.kext into the system.

The solution is to copy those files from the original DVD to the corresponding location on the harddrive: from (DVD)/ System/ Library/ Extensions/ * to (HD)/ System/ Library/ Extensions/ *

This solution came from an old 2011 post on sysprobs . com, from a commenter named Semi, to give credit where it's due. :D

Thanks, and I hope this helps someone else in the future.
