Hello world!
I’m Arthur—technical writer, teardown engineer, researcher, and photographer at iFixit.
I have the illustrious honor of taking devices apart, identifying components, figuring out how things work, and showing others how to fix stuff. In addition, I perform electrical analysis and research how emergent tech works.

Education
I graduated from Cal Poly, San Luis Obispo with a master’s degree in electrical engineering, with a focus on control systems and mechatronics. Along the way, I designed high efficiency DC power circuits, grew organic OLED panels in a vacuum, and programmed a small swarm of robots to autonomously navigate and map out a cluttered room. My thesis work involved training neural networks to detect hidden structural faults in commercial buildings using acceleration sensor data. I enjoy both the theoretical and practical hands-on nature of my degree.

“By teaching, we learn”
Much of my time at iFixit is spent instructing people how to fix stuff by writing step-by-step repair guides. So far, I’ve written over 180 guides for devices ranging from Rug Doctors to iPads. As I research, disassemble, and document repair procedures, I’m always learning something new. Working on smartphones necessitated a good understanding of how lithium-ion batteries work; writing Rug Doctor guides taught me how to remove rivets— something I haven’t had to deal with in smartphones…yet.

I am also a member of iFixit’s team of teardown engineers, publishing informative, in-depth reports on the inner workings of newly-released gadgets such as the Magic Leap One and the iPhone XS. These teardowns include chip analysis and explanations for complicated concepts (such as waveguides) in layman’s terms.

Interests
I’m curious by nature; I enjoy exploring long-forgotten roads, trying non-mainstream food, and disassembling new smartphones! I like retro, well-designed mechanical machines; I own four typewriters and drive a Suzuki Samurai.

The good news is that the memory model is common and brand-agnostic, so you can find it online. Search for 8GB DDR4 2400 PC4-19244 260 pin SODIMM memory, and any results should work.
Sorry! This should be the right model. Unfortunately, it looks like we have low stock on the RAM.
Hi Tristan!
This was back in the day when Pentalobe screws were new and controversially proprietary. iFixit sold kits that replaced the screws with common Phillips screws as a gesture towards reparability. Now, Pentalobe screws are considered common, so this guide is not as useful anymore.
The Face ID hardware is paired to the logic board and will not work if you transfer the front sensor assembly. Everything else should work.
Thanks! I will correct the step with the right screw size.
The silvery arcs are magnets as you noted, but they are there to hold the magnetic ear cushions. There is definitely adhesive holding the plastic ear cup grilles in place. Since there are four nifty twist-lock tabs already holding the grilles, maybe the adhesive helps dampen vibrations or buzzing?
Good question! You should replace the back cover adhesive with either a custom-cut adhesive or double-sided tape such as Tesa tape. You can choose to reheat and reuse the existing adhesive, but there may be a chance that the back cover will fall off. If you’re reusing adhesive, be sure to remove any uneven adhesive chunks.
The cable has a coaxial connector and can be slightly tricky to click back. Make sure to align it properly and press it down firmly with your fingers.
Hello! Isopropyl alcohol should not damage the plastic surface.
Hi Len,
It so happens that we sell the exact RAM you’re looking for at a much lower cost than Apple! Before you purchase the RAM, look over this guide to get an idea on how to replace the modules.
