stop charging while plugged in
Is it possible to change the internal operating system of apple's charging methods? So if I want to make an app or some code to make a MacBook stop charging at a certain percentage while it's still plugged in and then let the battery drain until 20%, it automatically starts charging again to 80%. All while it's plugged in. Does apple allow this? to make something like this?

Reply to iPadOS 15.5 beta 3 incompatible Apple Pencil 2
Still experiencing the same issue here - 15.5 w/ Apple Pencil 2 on iPad Pro. Nothing I do seems to get the pencil to be registered as an active Bluetooth device. I’ve tried disconnecting the magic keyboard, restarting, resetting, and “forgetting” the pencil with no resolution. We need this patched ASAP - I’m sure I’m not the only professional artist who is scrambling to find alts for digital art production because of this.

onTapGesture is working for finger, but not Pencil
Here's a weird one. Do I need to do something different to handle Pencil taps, or is this a bug?The following code shows a standard `Button`, and a few of custom Views called `SelectButtons`. The `Button` registers a tap with a Pencil or finger, as expected. The `SelectButtons` only work with my finger, on my iPad Pro. The Pencil taps don't register. struct ContentView: View { let nums = [1,2,3] @State var selected: Int = 1 var body: some View { VStack { Button(action: { print(Test button tapped)}) { Text(Test button) } ForEach(nums, id: .self) { num in HStack { SelectButton(num: num, current: self.$selected) Text(Number (num)) } } } } } struct SelectButton: View { let num: Int @Binding var current: Int var isSelected: Bool { current == num } var body: some View { ZStack { Circle().inset(by: 5).stroke() Circle().inset(by: 7).fill(isSelected ? Color.blue : Color.clear) }.frame(width:40, height:40) .onTapGesture { print(SelectButton.onTapGesture (self.num)) self.current = self.num } }

Reply to Apple pencil force non-perpendular force calculation
If you are pushing the pencil along its axis then the force perpendicular to a surface will be a fraction of the force along the axis - you want to divide the exerted total force along the pencil axis into two components - one perpendicular to the surface and one parallel to the suface. The component perpendicular to the surface will be smaller than the whole by a trigonometric factor - you want to multiply by the sin. BUT..........But you don't do that because the pencil will slip along the surface! Instead you torque the pencil into the surface. (Actually you learned this technique in Kindergarden and that's why you broke all those pencil point tips because you were trying too hard.) The result is that the pencil tip only exerts a force perpendicular to the surface and there is no slipping force along the surface. The surface pushes up against the pencil point and you divide that total force into two components - one perpendicular to the axis of

Reply to Apple Pencil and iOS 11 issues
it’s not just you I’m not having as big a problem but it sounds like alot of you are tho , although I did have that problem about a year ago but it seems since the betas most noticeably when installed beta 3 that’s when I noticed just random bugs I guess is the best way to put it in the pencil because I use the pencil for everything I love it ..... however recently it’s been acting up especially when I’ve been in Safari and things I guess the best way to put it is just are not clicking like they work I was in Pinterest today and I found myself having to use my finger because my pencil was not sensing screen so I I don’t know what’s going on but I use the pencil for everything as well you should be able to use the pencil for everything I don’t know why you can’t to pull up docs the dock and would you turn the top that’s ridiculous but that’s for another time ..I don’t understand why you can’t use Apple Pencil to bring up the dock or bring down your
