Hi everyone! Firstly, I'm new to the forums so I'm looking for some enlightment. I'm also new to buying macs (though I have had iphones and ipads in the past). A friend of my mum's is selling their imac for £550, and I'm trying to figure out which imac it is, as, oddly, they haven't actually told me. The specs are: i7 Processor 12gb Ram 2TB HD 27 inch Screen While I realise this isn't much I was hoping there might be some bright spark on here who might be able to help me out! I've provisionally said yes, barring it being pre-2012 (I've heard that the 2011 imacs have some crashing issues?), but as they're bringing it to me on Sunday, I'm not sure they will get back to me before then. If anyone could help me I'd much appreciate it!
