The proposed solution by Henry Gross-Hellsen is the most common one, and honestly the only one so far (See Linked & Related questions on here). I have not seen any other answers in researching this question.
It didn't work for me, but there are quite a few people responding that it worked for them.

Dude, i can tell you from personal experience; after buying four different usb-c hdmi adapters that the ONLY adapter that enabled me to utilize my external monitor full resolution + high refresh rate without having to hack internal /System/Library code or messing with SwitchResX/other b.s. GUI garbage;
is the belkin usb-c to hdmi adapter (the white version, ...
I installed the Intel Power Gadget to check if anything can be shown.
Then one time I left YouTube running, showing 1080p, and placed the Macbook 12 inch on the bed, and an hour later, I saw that the notification said CPU performance has been reduced, and Intel Power Gadget shows:
so it seems like the Blue Line (for the processor) is showing that it was ...
There is a known issue with the Macbook Pro Mid 2015 waking from sleep. There isn't a single solution, but there is an Apple article about it. The short version is to disable power nap on the "On Battery" and "Plugged in" power save settings in System Preferences.
Assuming that the monitors use an IEC plug on the backside, you can use an IEC cable splitter, like this
to grab the mains power from the monitor power cable and gain an extra power plug.
Then use an adapter like this
The USB ports in the Desktop and monitors don't provide enough power to charge your MacBook. These ports tend to be build "to spec", meaning they output only about 500mA (USB 2.0) or 900mA (USB 3.0). Sometimes PCs have dedicated charging ports (maybe colored yellow) which provide more than 1A (they exceed the official USB specs), but that's still not nearly ...
If the above don't work, which I imagine resetting the NVRAM won't since that's what you do each time, you can try the following:
Your Mac might be in Safe Sleep. To wake from Safe Sleep, connect
your Mac to its power adapter and press the power button. Make sure
that your Mac isn't turned off. If your MacBook Pro still won't wake
up, follow these steps to ...
I know you've already reset the NVRAM, but the first thing I'd try is to reset both the NVRAM and SMC in that order. Before following the steps below, ensure you have no external hardware connected and make sure you use the built-in keyboard.

Your Mac uses Non-Volatile Random-Access Memory (NVRAM). Here’s how to reset the NVRAM on your ...
For starters, no, the LG UltraFine 5k 27" display will not power the 12" MacBook (Early 2016) models.
As for being able to out put video to the LG UltraFine 5k 27" display, this is not officially supported by Apple. See Use the first gen LG UltraFine 5K Display with your Mac and Use the second gen LG UltraFine 5K Display with your Mac
However, it may be ...
The first thing I would do is reset the NVRAM.

I was using the Hyperdrive Pro Docking Station, and apparently its sharing the signal for its HDMI and DP port. I had to buy an adaptar (USB-C to HDMI) to attach the second monitor to the hub, and this solved the issue.
According to the information on everymac.com, the Early 2015 MacBook Air has a PCIe SSD while the Early 2013 MacBook Pro uses an SSD with a SATA interface. The everymac.com page implies that the Pro's SSD can be replaced with a 2.5in drive up to 7 mm thick.
This ought to mean that you could either look for a PCIe to SATA adapter to use the drive from the ...
Unfortunately the 2.4 GHz band, which Bluetooth uses, is rather crowded. Therefore interference with WiFi (802.11b/g/n/ax), microwaves, USB 3 devices, etc. are quite common. Apple has a support document on the issue and suggests a list of measures (see the link for all suggestions):

See what I was saying above in comments. I don't have a Mac and do not know if they have it, but I have an HP laptop with airplane mode button on it. When I want to disconnect before I close the lid, I just hit that. Done, no connections. When I come back I open the lid and hit the button again to reconnect and thats it. Maybe the Mac has a simple airplane ...
You could install blueutil and SleepWatcher via homebrew and set a .sleep code to call blueutil in order to disable bluetooth and call "networksetup -setairportpower en0 off" to disable wifi when going to sleep mode or closing the lid.
Blueutil comands are "/usr/local/bin/blueutil -p 0" to disable bluetooth and blueutil -p 1 to enable it.
To use ...
It may work, but at the least, you won't be able to close it properly. The LVDS cable is similar, but not identical, so you may have some extra cable parts floating around inside the enclosure. Short answer: it may work, but it is definitely not recommended. The way the top case (display) connects is slightly different. The screws would fit in the correct ...

Can you verify your keyboard is set to the correct language?
Many "wrong password" inputs come from non-english keyboard layouts, e.g. z and y are switched on german keyboards, usually not a problem, but in recovery or single user mode the OS only understands english if not set otherwise.
Many MacBook models will not power up if the battery is basically dead. And, reading between the lines I'm assuming this is an older model MacBook which probably still has its original battery - and therefore at much greater risk of having a dead battery.
You could try powering the MacBook up while connected to AC power and without the battery installed (...
Not likely. Apple can't ship these devices by air due to safety reasons, and there are a lot of them.
If everyone who was inconvenienced by this got together and collectively sued Apple, and won, you might get enough to pay for a fast food meal. In 2024.
Things to try in your situation include:
switch your external display on first, followed by switching on the MacBook Pro (within a second or two) - hopefully it'll get the signal it needs to display the MBP's output
if the above doesn't work, and assuming you only have the one user account, then switch on your MBP and wait long enough for it to be at the ...
Select all photos you want to move (in downloads folder in Finder), go to Edit menu-> cut. Go to desktop and in Finder, Edit menu-> paste.
For photos, Go to File -> import -> navigate to downloads and select using command-click or shift- click and hit review for import. Then finalise.
Have you tried reverting to the original macOS that was shipped with this system? If you can reproduce the same behavior with Mavericks/Yosemite then you could very well confirm that this behavior is rooted in an SSD failure vs file system issue.

Your model MacBook Pro can power external displays at 60Hz in the following combinations:
One display at 5120 x 2880 resolution with over a billion colors
Two displays at 3840 x 2160 resolution with over a billion colors
Two displays at 4096 x 2304 resolution with millions of colors
So, to use both the 5K and 4K displays you need to be mindful of the ...
I would try a third party executable that will allow you to list and change the screen resolution from the command line. cscreen works on macOS Sierra, High Sierra, and Mojave, there are also several projects on Github, but your mileage may vary.
Have you tried turning off auto-brightness on your Mac? That could be why it keeps adjusting the brightness by itself after a while (i.e., its ambient sensor thinks your display should be a different brightness and changes accordingly)

My experience with my MacBook Pro (Retina, 13-inch, Early 2015) is consistent with what Kevin Grabher posted: that the power adapter is not sufficient all the time.
The power adapter that came with it, however, is much better than the one I used before the battery ceased to charge. The one left over from an old MacBook would allow it begin booting before ...
CTR-Click is essentially right-clicking the mouse, and there is no way of remapping the keys without downloading 3rd party applications.
Karabiner can do this for you:
You can use it to map CTR-Click to left-click and it should work as you want it to.
Apparently, the MacBook Pro can only power external displays up to 5K resolution.
What you can do to use both the monitors is:
Connect one of the monitors (preferably the 5k first) and lower it's resolution way down, up to 720p perhaps, by following the steps as illustrated in
Then connect the other monitor(...

Efter dyas of works I found the solution here.
Here are the steps to fix the problem:
Go here and download the A USB flash drive image file
Unzip the file
Insert a USB stick into your Mac or Linux
On a terminal run diskutil list and find your USB key (for me was /dev/disk2)
Run diskutil unmountDisk /dev/disk2
Run dd if=refind-flashdrive-0.11.4.img of=/dev/...
Had the same case with first and second macbook pro.
I think I found the problem and a solution. So it's not the battery that is faulty but it's just the system that doesn't recognize the correct battery level. So when it says 100% it's actually at ~70%. and when it indicates 35% you actually really are at 0% that's why it turns off.
SMC reset alone didn't ...
As you stated in your post, this is a feature of various 2016 (and later) MacBook models, it is not supported on your 2013 MacBook Air.
I suppose you could get into the habit of putting your MBA to sleep instead of shutting it down, as this would mean it'd start fairly quickly upon opening the lid, but of course that's not the same as auto boot.
