M4 deleted Macintosh HD black screen fix.

recovery for Mac mini m4 deleted main drive into activation lock from black screen no video.

Hold down power for 10 seconds so the system shuts down.
Hold down Alt and push power on normally and hold alt for three minutes and let go of alt.
You should be at the activation Lock Screen, enter your email or phone number for the account and password. I used email.
You will now be able to reinstall OSX!

Mac mini, macOS 15.4

Reinstallazione OS X I have found an used iMac 27" ( late 2009 ). When I turn it on, the Utilities window appears. Then I select Reinstall the OS ( it appears 10.10 Yosemite ), the hardware is verified through the net and the procedure goes on. immediately after this, it asks me the Apple ID; I insert my credentials, but the systems says that ID or password is wrong. But they are certainly valid ( although different w. r. those of the previous owner of the iMac, of course ). As a net result, I' m unable to reinstall the O. S. and therefore the Mac seems to be unusable. But It is a pity, since it has 8 GB RAM, 512 MB on the graphic board, 1 TB of SATA disk and a quad - core Intel CPU ( I found these info through the terminal commands ). I hope some expert can help me. Andrea

how to revive a dead macbook air (recovery issue)😭 I have a 2020 Macbook air intel which I'm trying to get up and running. it had or has activation lock but i already fixed that problem. I can't get it to work, every time I start in recovery, only the internet recovery part comes out. it doesn't boot into usb, but it doesn't read usb either. I created the usb with transmac from Windows. maybe I'm doing something wrong. Any suggestions to erase and re install the OS? how should i create the usb, what key to boot from the usb?

Doesnt recognise my apple ID and Re-instaling the OS on 2009 - 2010 Imac I just bought 2 Imac, where the previous owner deleted everything from the disk ( reset to factory ) but wasnt able to instal the OS again. Imac24" : It goes to the utility, I have the Mac OS X there ready to install, no issues, all good, next next , accept, next , "loging to app store" insert apple Login and Pass ... and here is where all comes to a stop, becasue it says My login or pass are not valid when I know they are... using them right now to write this. Notes: recognises the "option" hold, to chose what disk to start with, recognises the "option+cmd+P+R" and does it all to the chose language, and then utilities again. DOES NOT recognise the "cmd+R" or any to grab the internet recovery. Imac27" : It gets stuck at 100% of loading bar, It does not enter Utility, "cmd+R" goes to internet recovery instead of Utility and going through the "download" it stays stuck on 100% loading bar ... left it on the entire night .. nothing happened, just stuck on the Apple logo with a full loading bar. Recognises the "option" , but doesnt show a recovery disk... only shows 1 disk. Neither one seems to recognise my external drive with an installed MAC OS .... So.... anyone has any other idea or options I could use, before opening them up and change their Hardrives or try to directly install a new MacOS through USB ? Thank you
