A German repair shop has found a way to fix malfunctioning lid angle sensors in the MacBook range by sidestepping Apple’s hardware encryption with a new tool.
The device, called the Nerd.Tool.1, was developed by Dortmund-based NotebookNerds and it specifically works on the lid angle sensor in MacBook Pro and MacBook Air laptops. If damaged, the sensor won’t turn the screen off when the lid is closed, which will drain battery because the device is still powered on.
Typically, a repair involves scraping away any corrosion on the sensor (water damage is one of the more common reasons for a mangled lid angle sensor) and hoping it’s intact enough to be reused.
The simplest and easiest route is completely replacing the component. But that can only be done at the Apple store because the new sensor needs to be calibrated using Apple’s pairing software that is only available to select organizations. Repair specialists argue that this is expensive for consumers because it reduces choice.
Stephan Steins from NotebookNerds claims that the Nerd.Tool.1 can calibrate a replacement sensor without using Apple’s pairing software. Check out the tool in use in the video below.
Ricky Panesar, founder of repair specialists iCorrect, says this a gamechanger for the current generation of MacBooks. “We all thought the [the lid angle sensor] was paired to the logic board in a way that you could not copy the data over…but he’s been able to copy that data, which is genius.”
Apple’s hardware is notoriously difficult to repair for third parties because of the company’s policy of serialization. This is where certain components in Apple devices parts are paired to the logic board and can’t be replaced, even with parts from the exact same model, without losing features if Apple’s calibration tool isn’t used. That tool is only available to Apple and Apple-certified repair shops.
The Nerd.Tool.1 is seemingly the first piece of kit to do this independently, although it only works on this specific MacBook lid angle sensor. Panesar told me that a similar tool wouldn’t work on other serialized components in other Apple devices, like the iPhone 15, because they have a deeper level of encryption.
NotebookNerds confirmed that the tool was only developed for the MacBook Pro and MacBook Air lid angle sensors, but the company hopes to expand the tool’s possibilities in the future.
“The nerd.tool.1 for now just fixes the problem with the lid angle sensor. It has an extension port which should offer the possibilities to fix other problems too. But these are plans for the future. We are mainly focused on MacBooks, less iPhones, but the plan is to give the community a development board to tinker around an find solutions for other problems. So we will try to build new tools but we also want to empower the community to do so,” the company explained to me.
Will Apple increase its level of encryption on the lid angle sensor now that this tool has been invented? The company has paired key components to the logic board across its device range, which affects functionality if repairs are completed without Apple’s authorization. But Apple may be softening its attitude towards serialization. iOS 17.0.3 bought back previously disabled camera features if the iPhone 15 selfie camera sensor was replaced. Last month, Apple also u-turned on its opposition to a Californian right to repair bill that would make it easier for consumers to repair their electronics. How the company responds to the Nerd.Tool.1 remains to be seen.
