All of a sudden today, apps that normally ran on my Macbook stopped working. I went to get info and sure enough they were PowerPC apps but they used to work for me (apps such as Limewire, Clutter, etc.) The only thing I can think of was I downloaded the app Downsizer earlier just to have, and that may have interfered. I did not even run Downsizer, and I now have it deleted, however the problem is still occurring. Any suggestions would be grateful. Thank you.
