Hi All! I just recently obtained the new 2011-edition 17" MacBook Pro. Although it's quite a very high-performance machine, it seems to have a definite consistent problem. Every time I connect my iPhone 4 and enable USB tethering, the computer almost immediately crashes, asking me to manually shutdown/restart the computer (in several languages). I'm still using iOS 4.2.1 and Bluetooth tethering still works (albeit obviously slower than USB). I've installed BootCamp and confirmed that USB tethering still works in Windows 7 perfectly. I've even installed Parallels and assigned the virtual machine to use my iPhone 4 as the primary network, and VM USB tethering works perfectly as well. However, USB tethering in Mac OS X only seems to be a major problem This problem never happened to my previous MacBook Pro(s). Has anyone else experienced this? Thanks much for the input!
