Following dismantling the latest refreshed MacBook Air models yesterday, today iFixit dives inside the new MacBook Pro model that arrived this week with upgraded internals and more.
On Monday, Apple’s 13-inch MacBook Pro received an update alongside a refreshed MacBook Air lineup and with it gets the new Force Touch trackpad that Apple debuted on its brand new 12-inch MacBook this week. The trackpad doesn’t actually push in like previous generations, but it provides enough haptic feedback to provide a similar and reportedly improved experience. Here’s what was discovered in the teardown …

Apple’s “Taptic Engine” is powered by an array of electromagnets that rapidly push and pull against a metal rail mounted beneath the trackpad, to create a tiny “buzz” of feedback with each click (and a second buzz for a “force click”)… Based on the wiggly pattern of traces stuck to the metal tabs, we’re pretty sure the magic pressure sensors in the new Force Touch trackpad are tiny strain gauges. Mounted on flexing metal supports, they detect the amount of flex on each—and based on that, the force from above.
iFixit gives us its usual rundown on internal components, some of which aren’t disclosed by Apple:
• Intel SR26K Dual-Core i5-5257U processor with Intel Iris Graphics 6100 • SK Hynix H9CCNNNBLTALAR LPDDR-SDRAM • Cirrus 4208-CRZ HD audio codec • Intel DSL5520 Thunderbolt 2 controller • Texas Instruments TI 58872D • Fairchild Semiconductor DE46SY • SK Hynix H5TC4G63AFR 4 Gb (512 MB) DDR3 SDRAM • Texas Instruments/Stellaris LM4FS1EH SMC controller • Broadcom BCM15700A2 • Texas Instruments HD3SS213 DisplayPort differential switch • Samsung S4LN058A01 PCIe 3.0 x4 AHCI flash controller • Samsung K4E4E324ED 512 MB LPDDR3 DRAM • Samsung K9LDGY8S1D-XCK0 16 GB flash storage • Parade Technology PS8401A HDMI jitter cleaning repeater • Genesys Logic GL3219 SDXC card reader controller • NXP Semiconductors PCA9501 8-bit I/O expander
Apart from the fancy new trackpad, though, the MacBook Pro earns a 1 out of 10 repairability score from iFixit for what it called a “gluey mess of a battery, soldered RAM, and other proprietary problems.” Don’t expect any repairs of the new trackpad to be easy, either: “the battery covers the screws holding the trackpad in place, meaning it’s impossible to replace the trackpad without first removing the battery.”
