iMac 21.5 Late 2015 Purchased new by a single owner. Used in a smoke-free environment, no pets. No heavy workloads, and it was not left on for extended periods. I used it without noticing any particular issues. To the untrained eye, there appear to be no color irregularities or screen burn-in. Surface: I couldn't find any with my own eyes, but there should be very faint wiping scratches. Back: Minor scratches (red circle in the 5th photo) Foot protection film: Still attached from the time of purchase (6th photo). Memory: Upgraded to 16GB Initialized. Only the main unit and power cable are included; no other accessories. The shipping label will be affixed directly to the original box. iMac (21.5-inch, Late 2015) - Technical Specifications Display 21.5-inch (diagonal) LED-backlit display with IPS technology 1920 x 1080 pixel resolution, supports millions of colors Processor 1.6GHz dual-core Intel Core i5 (Turbo Boost up to 2.7GHz) Memory 16GB 1,867MHz LPDDR3 onboard memory Storage 1TB (5,400rpm) hard drive Graphics Intel HD Graphics 6000 Video Support and Camera FaceTime HD camera Simultaneous support for the native resolution of the built-in display and an external display (up to 3,840 x 2,160 pixels) Supports extended desktop and video mirroring modes Audio Stereo speakers Dual microphones 3.5 mm headphone jack Headphone/optical digital audio output (mini-jack) Supports Apple iPhone headset with microphone
