Macbook Pro Retina hangs when making new scene

Can you give me any possible reasons why my brand new i5 Macbook is hanging for about 15 to 20 seconds every time I try to >Split Current Scene in timeline workspace?

I don’t have any extra apps running (apart from iPhoto).

The project file has an mp3 audio track of about 6 MB but is only about 40 MB total size.

I usually lay my audio track down and create one long panel over everything, then divide that up into panels. As I draw in the panels, I divide up the scenes where needed.

I was using v2 on a older machine (2008 Macbook Pro) and didn’t have this problem.


It could depends on the RAM on your computer

It’s got 8 GB. Not tons, but enough that I don’t think it should hang so long.
