I'm close to losing my mind. I bought a Snow Leopard disc to try and get things running better on my MacBookPro and it's pretty much done the opposite. I have a Lexmark X1130 all in one printer/scanner which now cannot be made to work. I've tried downloading the so-called latest drivers from both Lexmark and Apple...no joy. If anyone knows the magic way to sort this - please share it! I also upgraded my Google Chrome to the version for OS 10.6...only to find that apparently my Mac can't operate it. I've given up on that entirely and switched to Firefox but it's a right pain. As I wait to find out what else is going to go horribly wrong...feel free to warn me in advance!
