Try not to rename it. Leave 'untitled' as label and rename it afterwards.

LOL but I've never even seen an SSD like that before Quit simpler then the old ones Thanks
[automerge]1590172693[/automerge]
Is there any other way to wipe that SSD clean out of the macbook air ?

Are you booting to internet recovery? That's probably the best way to erase the SSD, assuming it is still good.

How to reinstall macOS - Apple Support

You can use macOS Recovery, your computer's built-in recovery system, to reinstall the Mac operating system. Reinstalling macOS doesn't remove your personal data.

support.apple.com

Boot holding the keyboard combination of Option-Command-R.
You will see a spinning globe during boot, rather than the Apple icon.

 

[justabrake]

I’m trying that now but I’ve been here before
I think there’s a virus in this computer

 

[Taz Mangus]

Try doing a SMC reset and then try the erase again.

Remember to disconnect from the beta of macOS 10.15 if you are interested on going release channel only - I think your computer will be activated for macOS beta despite a reinstall?! Someone can probably tell more about that.

If you want to get off the beta, that is.. I would, but that shouldn't mean you should too. There's shouldn't be anything hindering you in reinstalling macOS. The way to get a restore image of macOS Catalina is to download macOS Catalina 10.15.4 through the Mac App Store. That won't help you now unless you haven't totally gotten to erase your SSD yet, then boot back to macOS and download macOS Catalina - you won't have to sign in to Mac App Store to download the "Install macOS Catalina" app. Just search for it and click the Get button.

Depending on where you're deleting from, assuming that you at least have a chance to get to a Recovery Boot - use the Terminal on the recovery partition to erase and format the drive in question

diskutil list

Find the SSD - check the size in GB

diskutil eraseDisk JHFS+ Macintosh\ SSD disk0

or

diskutil eraseDisk JHFS+ Macintosh\ HD disk0

diskutil eraseDisk JHFS+ "Macintosh SSD" disk0

or

diskutil eraseDisk JHFS+ "Macintosh HD" disk0

- might be disk0 in your case - please check up on that.

you decide if you want to use the quotes code or the back slash. That's why there's two similar sounding commands.

If there's no way access any other Mac - look into getting on a Windows computer and see what tools are available for making a solid macOS install of Catalina on USB.

I might have been able to delete the HD not sure yet I’m downloading Catalina now I’ll get back when it’s finished

Thanks

I went and did this and it might have deleted it waiting for Catalina

 

[justabrake]

I'm on 10.15.4. with 121.12 GB

is something wrong here

 

[allan.nyholm]

Can you click the View button and have it Show All Devices.

 

[justabrake]

do you mean the finder tab

 

[allan.nyholm]

No in Disk Utility - gives a better overview of the drives IMO. The left most button there in Disk Utility

 

[justabrake]

Still not right. That's what happens when I try to erase the HD

 

[allan.nyholm]

I think you need to completely dismantle the APFS partition for this to work better for you. Try opening the Terminal and type

diskutil apfs

and try the

diskutil apfs deletevolume

or

diskutil apfs erasevolume

code


what are the details of the error? if you click the little arrow or press spacebar in that window? Perhaps unmount the disk beforehand.
I believe the ones giving you grief are the Macintosh HD - Data and such.

Edit... Or

diskutil apfs deletecontainer

I think that's it - now that I tap into my memory

diskutil apfs deletecontainer disk0

You'll notice that disk0 is what your SSD is. That's why I typed it out. Terminal is available in the Utilities menu of the Recovery Partition

I hope you have backups of all the stuff
