Mark would like to connect up to four monitors on his laptop. Can he connect two by USB? Leo says that it will work. There are a lot of USB monitors out there. But there may be a limit that the video processor can push pixel-wise. So it depends on your video card. Look at your specs. And if you are using an external GPU, you'll need a driver to do that as well. But don't go above 1080p. That'll help.
Brian wants to upgrade his MacBook Pro RAID drive and wants the fastest drive possible. Leo says that a Thunderbolt 3 external drive would be the fastest he can get for it. Leo recommends the Envoy Pro EX from OWC. It's also bus powered. But a 6TB drive is over $1,000, so it's not cheap.
Mark says that iTunes' user interface is horrible, and with iTunes 11, he can't get rid of a podcast. When he deletes it, iTunes reloads it! Leo says that other people report that it's deleting their music! So it's very manic. Mark says that iTunes won't load the playlists onto an iPad Nano because it deletes the media in the playlist. Leo says that is a known bug and it baffles Leo as to why Apple hasn't fixed that bug.
