Cubase 6.5 / Cubase Artist 6.5: 6.5.4 Update available

My friend, i’ve exposed this issue because Steinberg says I can open Cubase 7 project under 6.5.4, that’s why. With some exeptions about Cubase 7 features of course. But I didnt used any “special” features in the C7 project. I hope it’s more clear now.
I started a project under C7 but under OSX 10.7.5 it crash and CPU spikes, as other osx user reports. So they suggest to back to 6.5 and open the project but… I cant. 6.5.4 get more crash than 6.5.3 on my experiences on OSX 10.7.5 and 10.8.2 , if you are Windows user you should not have any problems as I saw on the forum users experience. Remaining in 6.5.3 still crash on quit somethimes. Looks like problems with Ram and 64bit management of the system. But i’m not a programmer, that’s what I feel.

Thanks for asking.
