I downloaded the new macOS Catalina last night and started having issues with my volume and laptop freezing. So I decided to try and out my laptop in a safe mode using the shift + power button, which never worked for me. I decided to just restart my computer the regular way and it’s just been stuck on the apple loading screen. I have tried doing disk utility recovery. At first, everything was okay but then I started getting the cross match error when I ran the first aid option. I have tried reinstalling the os but I cannot because my hard drive space is somehow now out of storage space, which it wasn’t before. I really don’t want to have to wipe my hard drive clean because I have a video I was working on in Final Cut Pro along with other files. I do have A old timeshare backup from February/March. But I would like to keep my files if possible. What can I do??? Safe mode never worked, I’ve tried the all the reset commands and they did nothing. My computer is now stuck on a boot cycle load that turns on and then restarts.
