There is no easy way to do this from within the computer (you could always measure it of course). The hardware on laptops only needs to know whether the lid is closed or not, so a simple on/off switch is enough and built-in. There are (at least) two threads on reddit where apparently the tilt level seems to control audio volume: https://www.reddit.com/r/...

This looks normal. The circular white spots are moisture indicators, which turn red on contact with water. This is to inform a technician if the logic board has been in contact with water to possibly decline warranty cover for repairs. The ‘white dust’ on the edges are part of the production process.

No it doesn’t. The new hardware and iOS can handle kiosk mode / constantly charged batteries much better than the old controllers so you should just keep it charged if you like that. Your XR can be kept 100% topped off without any long term harm. I disagree with Mac World and only think you should shut down the phone if you don’t regularly do that from ...

Yes, you can submit such apps! I have done so before and got them approved. You’ll probably be asked to provide more information about your setup, or be asked to provide a video of you actually using an iOS device to control the hardware.

I believe these are smart chargers, and initially only supply about 3 volts in order to power a power management chip inside the device to be charged. Once powered by the 3 volts, the power management chip inside the device then communicates with the charger verifying that the device is compatible to be charged, and if that fact is verified, only then will ...

I haven't heard about such incompatible firmware updates. I have dual-booted 10.14 (Mojave) and 10.11 (El Capitan) on the 2013 Retina MacBook Pro, which is almost the same configuration - and that worked without problems as far as I recall.

These models support a 7 mm tall SATA III (6 Gb/s) hard drive for the primary storage (using the 3.5" size as opposed to the 2.5"), and getting the Fusion drive means you'll also get what's called a small "blade" SSD via a PCIe connector. Without this you can't attempt what you're wanting to do. So, in summary: Primary storage uses a 3.5" 6 Gb/s SATA 3.0 ...

I have a scanner that looks exactly the same and works perfectly on Mac. Essentially this device works like a USB keyboard, and thus requires no special operating system or driver support. The device is NOT supposed to show up in The Finder sidebar, contrary to other suggestions here. To test the device, open Notes, TextEdit or similar app - then scan a ...

Shut down before you close the lid. Set the lid behavior so that it does not auto wake. I set that behaviour when I want to clean the keyboard but you have to avoid the power button...

Minimizing the risk is simple. Don’t charge the battery. Does’t matter if you are sleeping or shut down, the discharge doesn’t trigger a problem. The charging does. So just don’t use the Mac once it needs a charge. In case you're worried about the time to fix - here is a crowd-sourced list of times to repair: Battery Recall Turnaround by Apple*: From ...

Based on the answers to this question the supply doesn't communicate with a power management chip - it simply looks for a resistance of approximately 40 kΩ between its output and ground, and if this is detected then the full output voltage is enabled. Also based on the above answers, if you often measure 0.2 V rather than 3 V then an intermittent fault in ...

I had the exact same symptom just now on booting an MacBook Air (2014 I think). Regular 5 rapid ticks repeating every ~3 seconds were there. Seemed to be coming from the MagSafe port. After reading on this thread that it could be a fan issue, I gave the machine a couple of firm taps underneath the port. The fan immediately spooled up to full speed for ~1 ...

The accepted answer is incorrect. The outer wire sheath carries V-, connected to the outermost MagSafe pins. It's also connected to the inner metal part of the MagSafe connector, the part that snaps with the magnet. All of these were verified with a multimeter. When connected, it connects with the MacBook's ground system (checked with a multimeter). There'...

To monitor throttling, you may run: pmset -g thermlog in terminal and watch output: If CPU_Speed_Limit is less than 100 at some moments, then it means CPU is throttled.
