I'm looking for a used 13" or 15" MacBook Pro, and I'd like to know which models are good enough to run VW well, (for small and for mid-sized projects. I also work with Sketchup regularly.) I looked at the list provided by VW (many times over the past year), but honestly it's over my head. The terminology about graphics cards seems to shift constantly, so the I can't determine which brand or type most computers are. Any fool-proof thoughts on which years and models I can search for to hopefully come up with a good machine? (I'm thinking not more than 3 or 4 yrs old, just for serviceability. ) Thanks for any thoughts.

When I try to edit the custom title block I'm working on it just disappears. I can undo, and it reappears. But I can't seem to make any edits without it diesappearing. It is corrupt? Also I made a title block document. Now that I have something I like, I can't get it into a project file I'm working on. I tried copying it in, exporting. It doesn't show up. I think I'm completely unclear on how these components are organized to work together. One sheet border component. One title block record. seems to work in the original file in which i built it. Now what? I've tried 'adding a sheet border' to a new sheet in my project file and haven't succeeded yet.
