I'm currently on 10.5 Leopard and my apps and system are very stable, which is really boring so I want to upgrade the OS and screw everything up!
Only kidding - I want to enter the world of 64bit goodness and am tempted by Adobe's CS5 Production Premium pricing for the monthly payments. I'm very happy with M100 but Premier looks very tempting with its ability to ingest anything without transcoding and integration with AFX. I think one NLE is too limiting these days so ultimately I'll get Premier, FCP X and M100 suite as the costs are getting more reasonable.
In the short term though, am I going to need to partition my disc and run both 10.5 and 10.6 separately to keep M100 V13 working or can I install 10.6 without issues?
