audio – Disable Bluetooth roaming on Macbook Pro

Thus, my Macbook Pro (15 inches, 2018) often blocks the bluetooth and connects to devices (like my headphones) although it is powered by the battery with the lid closed. I would like to disable this functionality – seems to be a bit of a security / privacy issue.

Any ideas on how to turn off Bluetooth when the lid is closed?

15-inch MacBook Pro under macOS Mojave awakened with blue screen of sleep

So recently, I went home after a few hours on my MacBook Pro (plugged in all day) and saw this:

MacBook Pro screen

What would cause that exactly?

More information about my system:

  • Hardware: Intel Core i7 2.2GHz, 16GB DDR4 to 2400MHz, Intel UHD Graphics 630 1536MB, Radeon Pro 555X

  • Software: Xcode is installed on my computer and the applications that run in the background are Settings, Spotify, Atom (the text editor, with enough plugs -ins) and Chrome.

Update: Under Wilfred's suggestion, I made a diagnosis. Nothing has been picked up; it seems that there are no problems as a result.

macbook – How can I permanently disable Hot Corners on a Mac?

I have a working computer and whenever I turn it on and I log in, active corners are turned on. When I inadvertently move my mouse in a corner, my screen is locked. It's happening all the time in the middle of my work.

Everytime, it bothers me and I go into the System Preferences and set all the hot corner options on no. But the next day or whenever I restart my computer, they come back! I wonder if anyone knows how to disable them permanently. I do not need to manually disable them every time I restart my professional MacBook.

Is there a terminal command or something that I can configure to prevent Hot Corners settings from resetting permanently? I imagine that, by default, my company applies settings that override the settings at reboot.

Macbook air 2017 keyboard and trackpad do not work + other issues

my macbook air 2017 suddenly developed the following problems:

  1. the touchpad and the keyboard suddenly stopped working

  2. I run in bootcamp, but I can not go back to MacOS anymore

  3. CPU utilization reaches 100% when you perform simple tasks, such as opening Google Chrome

  4. In the device manager, there is an "unknown usb device (the device descriptor request failed)"

  5. The memory usage in the task manager is always at least 38%, the amount of memory used is less than 500 MB but my machine has 8 GB of RAM.

I guess 4. is at the root of the problem because a Windows notification appeared about the "unknown USB device" and that's when the keyboard and trackpad stopped responding.

Does anyone know how I can solve this problem?

Edit: I have also made a diagnosis of Windows memory and no errors have been found.

MacBook with faulty display – can not operate an external monitor!

I've been using my 2016 MacBook Air with an external monitor since I fell down and broke my laptop screen. I'm using a Displayport adapter that goes directly to the VGA (unfortunately, it was the only one I could find in my area).

I recently decided to clean my disk, after saving my files on icloud. I actually cleaned it up using the recovery partition. However, the laptop accidentally turned off the mid-installation after wiping my drive and giving it encryption as well as a password.

Now when I start it, the chime sounds, then I close the lid as I usually do, and I move the Bluetooth keyboard to wake it up – and the external monitor turns on to show my desk. However, he just stays black. obviously can not see anything on the internal screen, so I do not know what to do. I have tried cmd + F1, no go. I've tried to start it in recovery mode – the screen still does not turn on. I reset the CMOS, nothing.

Does anyone have any idea or advice on how to operate the external monitor, or what might not be wrong?
