New Mac User Questions, about Logic and OS X Options

[jean claude van ...]

Hello,

I'm using Mac for audio production only for few weeks now, so please forgive me those silly questions

Ok, so I've read on this forum that making two accounts on OS X -one for daily stuff and other optimized for music making is very good solution. Well... indeed it works fine, but I have some annoying problems with it too. I'm using Logic Express 7 and every time I open my song all the samples have to be reload again, software cannot save overview as this account doesn't have enough privileges for that. Do I have to change privilages to every folder ? Is there a way to set it globaly ?

Other problem I have is that Logic does mix/export audio to either WAV and AIFF format but neither of them can be played later with Quick Time and system don't know how to open this files. I overcome this problem importing it to Audacity (at least WAV files because Audacity don't recognize Logic's AIFs) I can live with that... but since I do everything on Logic (mixing and mastering too) it takes much more time.

And the last thing is memory in Mac's. I have G4 with 512MB. I don't use a lot of software samplers and much ram consuming applications... so the question is - how expanding ram to 1GB would change my system performance for my use ? Would it change it A LOT ?

I'm a bit affraid of reading what I wrote. Anyway it's a Getting Started Forum, isn't it ?

thanks !
