Can I use my iPhone to get internet connection to my MacBook Air? It has a problem installing the software. The 🌎 spins around trying to do an internet recovery boot. I’m not connected to the internet so what can I do

I have my hotspot on to my iPhone and it hard tethered to my MacBook Air. I’ve done this before with at&t and direct tv. I disconnected the internet but was able to plug my iPhone into the wireless modem and create a connection. I also just purchased a day pass for Xfinity WiFi but I was not the user in the MacBook Air

I did and it was searching for internet recovery, I already did everything to connect my MacBook Air to the internet but then this pops up

I just pressed the shift + ctrl + option + power button all 4 for about 3 minutes. I restarted my MacBook Air and now this is popping up

No, I just posted how to save your Apple devices from the black screen also known as the kiss of death 💀

I fixed it all by myself

To fix the kiss of death 💀 screen simply hold the shift + ctrl + option + power button down all at the same time for 15 seconds. Plug your power cord into your Mac or 💻 air or pro, then hold the option + command + P + R + power, hold for about 25 seconds. Your computer will make a couple of booting noises about 3 times. Then you will see a file folder 📁. Power off your device then pres the power button + command + R, when your device starts immediately let go of your power button. Wait to let go of your other two keys until you see a globe spinning...RELEASE! You will then be asked to select a network to login to internet reboot your device
