Yesterday I tried to update to the newest MacOS. First it failed bescause I had not enough space on my mac. Before second try I got the messegage that there was not enough space, so I deletet things and then I had like one more gb than I needed for the update. Should be working..... I started the update.... Mac restarted.... I think then there was the Apple Icon with the status bar, rest black....? Dont remember every step exactly. Later I came to the login Icon. I loged in. Then there was the Apple Icon with status bar, rest of the screen was the catalina image. The status bar went to like a third of the bar, then the hole screen went black. I tried waiting, nothing happend. Only way to get an image is to press the start button. It then turnes on and shows the same login screen as before. When I log in again, the same thing happens again over and over. (I tried this like ten times) Also tried some shortcuts. (turn off - turn on with holding shift, turning on and immediatly press command option r p, also with just pressing command r or option p. I am maybe describing it wrong - dont know.
Basically I was not able to startup the mac.
I pressed certain command to get the mac into recovery mode. Worked. The screen looked like as what it looks like when you set up a brand new Mac. Language, Apple ID, Password etc. Did all this. Then there was the option to recover from timemashine backup, to repair harddrive storage thing or to delete all things on it, there was also the option to reinstall macos, or to get help via safari. (those four options as shown below) I connected an external storage disk and reinstalled macos on it. Mac worked when this storage was connexted. (I did this because I didnt want to lose my data, or there was not enough space for that on the mac) With the new macos on the storage disk, mac seemed to be working. My data is not shown. Thats maybe because its running on an external disk or it has been deleted, I thought. Started that storage disk application. It showed that the internal storage was exactly as before I tried the update (~110gb of 128gb) -> think my data is still on that harddrive.
Right now I turned the mac off and disconnected the device because of time, I mean it was already like midnight and I had to sleep. The mac now shows the login sign when powering up without external disk - I also think when when powering up with. I think you will need to install macos again on the disk. Have no idea basically - That problem made me crazy.
Its again failing to login with no external disk with macos installed....
Can somebody show me what to do - I mean like step by step because I am really confused.
If there is a way I would also like to keep my data.
Sorry for that long text
Thanks for your help.
I'm soooo confused
