Hello, My upgrade to SL has been a relatively smooth one compared to what I've been seeing on the internet and around here. My question doesn't really have to do with a problem as much as I just need information. It is my understanding that Aperture and Sibelius require certain newer versions of their software to run under SL. For Aperture, if I try to install Aperture 2 and then upgrade, the software will not open at all. Is there any way to get around this? Same question about Sibelius; does anyone know the procedure for getting this to run on SL? Thanks!
