I got this imac, and i wanted to reinstall Snow Leopard (the cd is from a 2010 macbook pro). The imac notices the cd, and reads it just fine, but after selecting the main system language (which is now set to Dutch and should go to English) it just tells me that it cannot reinstall OS X on this imac. I googled some things but i can't find why its happening, i thought the software was supposed to be installable on multiple machines? Help is much appreciated! Thanks in advance.
