(By comparison, USB can connect up to 127 devices at once through a hub.)Īs usual, not everything on the inside of the new MacBook Pro impressed the teardown team. iFixit also points out that users can chain up to six Thunderbolt devices to one another, which could pose a problem in the future should Thunderbolt-compatible devices take off. "That's nice, as you don't want your display competing with your external hard drive for bandwidth," the team wrote. Apple advertised that the new I/O tech would support a 10Gbps throughput, but iFixit says that both PCI Express and DisplayPort appear to get their own 10Gbps data channel. IFixit clarified a number of details about the MacBook Pro's Thunderbolt implementation as well. iFixit also says that the MacBook Pro's RAM has been upgraded to PC3-10600-faster than previous MacBook Pro models-and that the wireless card now has four antennas instead of three.
The company points out, however, that the battery is held in with tri-wing screws, which could prevent the average joe from making a battery replacement. Other discoveries included the fact that the new MacBook Pro sports the same 77.5 watt-hour battery as the previous model, confirming that Apple has indeed reduced its battery life estimates from eight to nine hours to seven hours for other reasons (Apple cites a "new, more rigorous battery test").
"The only tricky repair is LCD replacement, which could easily result in shattering the front glass panel." "The unibody design also allows for easy access to most of the other components, so it won't be terribly hard to replace things on the machine," said iFixit. The gadget repair team said that Apple made a number of good design choices with this round of updates, though it also questioned Apple's quality control after making a few discoveries.Īccording to iFixit, the latest MacBook Pro revision allows you to disconnect the battery without having to take it out of the notebook altogether-a helpful move for tinkerers, since all power is supposed to be disconnected before digging into the machine's innards.

Hopefully the company extends that solution to future MacBooks as well-and eventually acknowledges why it exists in the first place.The crack team at iFixit has given the newest 15" MacBook Pro a "respectable" repairability score of 7 out of 10 after putting the machine through its obligatory post-launch teardown. Regardless of how Apple frames its new keyboard, it clearly helps keep dust out and solves a vexing problem. But any more thorough solution would likely have required a total redesign of the keyboard, and of the MacBook Pro generally, rather than strategic tweaks. Pouring sand over the keyboard-don’t do that at home-caused a few keys to seize up right away in iFixit’s tests. We used to break those a lot, even being careful,” says Suovanen.
Just going off of feel, I would guess that they changed the dimensions very slightly, and/or maybe the composition of the material they’re using for the clips. “The measurements are very, very slightly different. But iFixit found it could get them on and off on the new MacBook Pro without a hitch. Failing that, an entirely new unit might be needed, since removing individual keycaps risked damaging the underlying mechanism. Previous-generation keyboards were difficult if not impossible to repair Suovanen says Apple’s strategy was to hold the laptop at a 45 degree angle and hit it with compressed air. “I definitely think it’s going to reduce their headaches going forward, and certainly consumer headaches.”Īpple also appears to have done itself a favor in terms of repairability. “It’s not 100 percent effective at keeping debris out, but it’s pretty good,” says Suovanen. Specifically, a thin layer of silicone now sits above the keyboard’s butterfly mechanism-a protective layer that, yes, might make typing a little quieter, but definitely keeps more particles out.

While Apple has offered to fix any affected keyboards for free for the next several years, the new MacBook Pro appears to be its first attempt at a design-based fix. While Apple has previously downplayed the extent of the problem, it’s pervasive enough to have inspired three class action lawsuits, and prompted a rare acknowledgement from Cupertino last month that something is amiss. Debris gets under the keyboard and has no way to get out again, resulting in unresponsive keys.
But a detailed teardown completed by repair site iFixit Thursday shows a much more likely catalyst: keeping out dust and other particles, so that the keyboard won’t break.Īpple’s previous keyboard design (found on MacBooks dating back to 2015 and MacBook Pros from 2016 until this most recent version) has been prone to key failure. It also introduced a new keyboard design, purportedly to make things quieter. When Apple introduced its new MacBook Pro last week, it didn’t just infuse it with faster processor and more RAM.
