Hi, I have an iMac 2007 core2duo i7 that has started to be quite slow recently. I stil can use Logic Pro X on it, but it is getting at the end of its pro line usage. Otherwise, my mac is in excellent shape, since I take care a lot of my computers. It still looks brand new. If I were to revert to the initial configuration, would it recover it's initial speed (or close) and could I continue using it for basic email, web surfing and a few card games? I will get another mac for my pro software, but I find it a real waste not to be able to use my iMac 2007 for other usages. Selling is not an option. Putting my iMac in the garbage is not an option I'll consider due to environmental issues. I recycle 'old' iPhones because I am mad at all electronics going into the garbage around the world. That should not be allowed. Thanks for your advice.
