- is it feasible to install Rosetta under MacOSX for a not very computer-literate user?
Yes, but if you've never had to install software from source before it may be a little intimidating. (Not sure if they plan to release binary builds at any point - will check on this.)
- Phenix seems to slow down my MacPro a lot, even if I use just one of the 8 processors - is 4 Gb of RAM too little?
In general it is wise to have at least 1 GB per core, and preferably 2+ GB. The slowdown is probably due to other applications swapping to disk to make room for Phenix; adding memory will definitely help with this. The amount you actually need depends on what kind of structures you're working on - but keep in mind that other apps such as web browsers are also memory hogs. (Watching YouTube while refining structures on the same computer is probably not going to work very well with only 4GB.) -Nat
