Question

I got a new Macbook pro in March and transferred all of my old files into the new macbook from my old one. But ever since then, my iPhoto just does not open up. It says 'error' every time I try to open it, but I am still able to attach the iPhotos saved to emails. Help! How do I get my iPhoto back?

Answer 1

Thanks, Sig.
The old computer is a 2.6 Ghz Intel Core 2 Duo
The new one is a 2.3 GHz intel core i7
In going over this, thanks to "tallking it out" with you, I did discover the Text Edit problem.  Because I've still been unable to get the new computer text size (fonts or whatever) to match the old computer, I did not notice that the curser is now different--the line midway down the curser has to be placed on the line I am working upon, otherwise the edits go elsewhere on the page.  Now, with a bit of difficulty, I am able to get Text Edit to work correctly.
If you have any ideas as to why my menu bar and Text Edit type are still so slow, I'd love to have them. 
(I went through the process you suggested earlier, re my Trackpad preferences, and found no improvement.)
