In Windows, I can easily search for a file that ends in any file extension such as .ipsw (iPhone software) by searching my C:\ drive for files named *.ipsw So how on earth would one search the contents of a Mac's hard drive for the same file? I've only been using OS X for a few months but this seems like it should be fairly straightforward and yet I can't seem to figure it out for the life of me. This works fine for items such as documents/pics/music inside my user folder (.doc, .pdf, .jpg, .m4a, etc) but not for anything outside of it. So how do you do a REAL search in OS X - preferably not from the terminal if possible? Thanks!
