I received it about 8-10 days ago and just unpacked it  and started the process of getting it up and running and ready. Boot time is so long, I could start and probably finish shaving by the time it completes the process.  No joke. It has failed the system update a few times, but I'll give it another try or two.If it starts to function properly, I will likely upgrade it. Perhaps and external SSD boot drive and RAM. So far, I am wishing I bought something better. I am a Mac guy, but this model is not making me smile at all, aside from the screens quality. I will update as time goes by.Well, It's been doing and redoing the update.  Growing old waiting. Oh I have a 500 meg connection incase you are wondering. Hours and hours trying to update. SELLER, are you reading this?Update: It’s not happy about transferring the files from my old iMac. So time consuming to get this process working on this new machine I have no Smiles left for this product.Total downer. I gave up on it some time ago. My almost 12 year old iMac runs better and is more reliable. Do yourself a favor and take a pass on this one.
