Erased Macintosh and made my monday a little worst

Hey The_ruess!

Thanks for the kind words. Sorry to hear it came down to a repair, but getting to know your spirit, and determination, I’m sure it’ll work out fine for you!

We can’t always control the technology that we all so heavily rely on and use today, but we can control how we use it, and therefore have the responsibility of using it for good, and to help others as we’d like to be helped, when we need it, and we all need a helping hand here and there, so glad to do my part, no matter how small of a contribution it is.

Best of luck, and let me know how it goes, curious to see, and hope it works in your favor! Thanks!

I would like to try this  Linux boot disk please , and have a good night or day.

Download a Knoppix DVD .iso file for v8.6.1 making sure to get one with "EN" in the name for "ENglish". Use the Knoppix .iso file as a source for Etcher (Mac/Windows/Linux) which will create a bootable Knoppix USB stick. Option Boot the Knoppix USB stick and select the orange icon labeled "EFI". While Knoppix is booting the Mac may appear to be frozen on the boot picker menu so make sure to give Knoppix lots of time to finish booting. Make sure you have disconnected all external drives except for your Knoppix USB stick.

Once Knoppix reaches the desktop click on the "Start" menu icon on the lower left corner of the Taskbar and navigate the menus to "System Tools ---> GSmartControl". Within the GSmartControl app double-click on the Apple SSD icon to access the SSD's health report. Post the complete report here. You can also try running the long/extended self diagnostic as well. Even if the self diagnostic fails the secure erase could fix that issue (I've fixed several Apple SSDs with failed self-diagnostics).

Now launch a terminal app. You can click on the terminal app icon on the lower left side of the Taskbar. Now you will issue the following commands to get the Linux drive identifier for your SSD or you can retrieve the drive identifier from the GSmartControl app. If you've never used the command line before you need to press the "Return" key at the end of the line to execute a command.

List the drives to find the Linux drive identifier for the internal SSD (usually it will be "sda"):

sudo  lsblk  -f  |  grep  -i  sd

There will be two main drive identifiers listed with one being the Knoppix USB stick and the other one should be your internal Apple SSD (assuming all other external devices are disconnected and that the internal SSD is a SATA based SSD).

For all of the commands below make sure to replace my sample "sdX" with the actual drive identifier of your internal SSD.

Confirm the drive identifier you have selected is your Apple SSD by using this command:

sudo  hdparm  -I  /dev/sdX  |  grep  -i  model

Now you need to put the laptop to sleep for a moment by clicking the "Start" menu icon on the lower left corner of the Taskbar and selecting "Logout", then select "Suspend". Wake the laptop (I forget if you can use any key or whether you need to press the power button). Once it wakes run this command:

sudo  hdparm  -I  /dev/sdX  |  grep  -iE  '^security'  -A5

The output should look something like this:

Security: 
	Master password revision code = 65534
		supported
	not	enabled
	not	locked
	not	frozen

The important parts here are the "supported" line and the "not frozen" lines. If the " supported" line shows "not supported", then the Apple SSD doesn't support the hardware secure erase so you can stop here. If the last line is just " frozen" without the "not", then most likely the laptop did not make it all the way asleep so try "suspending" the laptop again.
