I need to download XCode for school but I am stuck on 10.7.2, because of all the "no sound" issues that I have had with the 10.7.3 update. I wrote a blog post on the subject here. My machine is completely useless to me without sound; I make YouTube videos and edit in FCPX every day. Do you guys think I should wait for 10.7.4 to come out, or try the 10.7.3 update again, or find another way to install xCode? Also, I would like to install the iPhoto update, which is only available with 10.7.3.
