I am writing this to inform people of the horrible experience that I had with my Early 2011 MacBook Pro. In November of 2011, I purchased an Early 2011 MacBook Pro. It was the base, 2 GHz quad-core i7 model with 4 GB of RAM and the 500 GB Hard Drive. It was rock solid until February, when the sound stopped working. Apple replaced the speakers, then said that it was fixed. However, when I went in to pick the machine up, the sound was not working still. They kept calling me and telling me to come in, that it was fixed. Each time, either the sound wasn't fixed, or some other issue cropped up. For example, one time, the backlights on the keyboard did not work, and the sound only came out of one speaker. They replaced the logic board, and that did not resolve the issue either. Their only option was to do a clean install of OS X Lion. I wrote about the issue here. 5 days ago, I took it into Apple to have the Logic board replaced AGAIN, because the headphone jack was very loose, and would not grab the plug when you inserted it. They replaced the Logic Board. I recieved the machine back on Tuesday night. All was well, until I was really using it that night. I started getting Kernel Panics and the dreaded 3-beep error. It would just freeze and do the 3-beep error, randomly. I tried resetting the SMC, PRAM, and replacing my Crucial 8 GB upgraded RAM with the stock 4 GB. Nothing worked. Yesterday, I took my machine into Apple after it had frozen with the 3-beep error, and then refused to boot up. I asked to speak to the manager after the "Genius" told me that they would replace the Logic Board again. IMO, for a Logic Board to last TWO DAYS in a machine is totally unacceptable. For a Logic Board to last 3 months in a machine is also totally unacceptable. I was not about to get my third Logic Board in under six months of ownership. I explained the situation to the manager of my local store. After much discussion with him, he agreed to give me a new machine: A Late-2011 2.2 GHz i7 with my 8 GB ram that I'd upgraded in the previous machine. Hopefully this ceases all the problems that I've had with my dud of a MacBook so far. A few of my tech friends have MacBook Pro's, and have had little to no hardware issues with them. What are your thoughts on all the issues I've had with my "Certified Refurbished" Machine?
