2011 MacBook Pro 15.5". This is a good quad-core machine that's been looked after well. I used it for a little while but have upgraded since then.<div><br></div><div><div>Buyer beware - all 15" 2011s have unreliable GPUs that die if they get too hot. This can be solved with some technical knowledge but it's best suited for people with technical experience. This one still works because I kept the fans high but I can't guarantee its continuing performance. If you want it disabled, I recommend https://doslabelectronics.com.</div><div><br></div><div>New battery installed, currently has 19 cycles. I tested its life to around 4 hours of YouTube playback.&nbsp;</div><div><br></div><div>There's some damage around the charging port but it charges fine.&nbsp;</div><div><br></div><div>I did a fresh install of macOS 10.13 High Sierra and added Macs Fan Control to keep the GPU working well.</div></div>
