Just lately I upgraded from Mojave to Catalina and I made a decision to encrypt my macbook’s SSD, and in addition it is frameware (it confirmed an extended password after encryption and I wrote it down).
After Set up I noticed considered one of my company softwares does not work and I made a decision to downgrade to Mojave once more.
So I attempted to make use of Startup Disk (in system preferences) to load from Mojave’s bootable USB stick, however it did not present up in there.
So I made a decision to enter restoration mode, however key mixtures did not labored.
Then I used terminal to power getting into restoration mode, I executed:
sudo nvram "recovery-boot-mode=unused" sudo reboot
Lastly I entered the restoration mode!
I deleted Catalina’s each partitions on SSD to put in Mojave, then unintentionally took off my usb stick, after connecting it once more, restoration mode wasn’t in a position to run from usb stick.
I rebooted the macbook, and it now exhibits a folder with query mark which implies cannot learn from bootable disk.
All I can do now could be powering on and off the macbook. Cannot reset nvram, cannot reset pram, cannot reset SMC, cannot boot into restoration mode. All key mixtures fail to work simply after Catalina set up. I attempted utilizing an USB keyboard however that did not labored too.
Additionally it is unattainable to ship macbook to apple for service as I dwell in abroad and there’s no method for me to ship it for service.
It is my work laptop computer, what ought to I do?
If you understand how to reinstall macOS, boot to restoration and even boot from USB stick (to load macOS set up or linux/home windows), please assist me.
System: Macbook Air 13″ (early 2014)
Obtainable bootable USB sticks: Mojave, Catalina, Ubuntu, CentOS, Home windows 10.
