Hi again, MacRumors Community! This time, I'm considering upgrading from Win 7 (installed in a bootcamp partition BTW) to Win 8 in my 2012 MBP 13". I got one of those promotional codes and thus I thought it would be a good idea to upgrade before it expires. However, the Win 8 installer is giving me a few warnings prior to the installation about stuff that won't work anymore after the upgrade. These include my USB 3.0 ports, my DVD driver and iTunes! To make my DVD work again, MS is pushing me their media center, which will cost me roughly $60, 4 times what I'll spend on the OS! And for the USB 3.0 they don't mention anything... Also, I've seen some videos on the web that mention sound and wi-fi not working after the instal Has anyone did this upgrade before? Have these issues been solved? Is it possible to get at least my USB 3.0 working again? Also, is it possible to just buy Win 8 through their upgrade tool without having to actually install it? This way I could wait until these issues are solved to upgrade... I appreciate any thoughts you might have.
