Hi! I am having some trouble. I am trying to reinstall software again but when I try there is no disk to select to install (attached a picture).
How can I create a disk? (Attached another picture of my disk utility).
could someone walk me through please?
MacBook Air 13″, macOS 10.13
Try booting into Internet Recovery Mode using Command + Option + R to attempt to access a macOS 10.13+ online installer. Use this key combination even if you are still booting to the Yosemite installer as it should not require authenticating to the App Store.
The reason you cannot select a disk is either because "disk0s2" is an APFS partition/container, or that partition is damaged. I suspect the former.
If you cannot boot into an online installer of macOS 10.13+ using the key combination I mentioned, then you will need to partition the whole physical SSD using the instructions in the following article starting at Step#2:

If this is an older MBAir which does not support macOS 10.13+, then you may run into a problem with the installer's certificate which may need to have the date & time set to 2017.

Click on disk0s2 and try using the Mount or Verify function. If neither of those works and you have a backup, erase it.

Hello! Thanks for replying. Unfortunately verify doesn’t work because it’s greyed out. I’ve clicked mount but that doesn’t get the disk to appear.
I don’t think I have a backup and I’ve just cleared the disk. Any other ideas?
