Hi dear all
After I update my MacBook Pro 2015 to Catalina, I faced some issues, so I decided to clean install my Mac. When I want to install new os from bootable flash (after holding option), I choose to boot from a USB drive. For some moment apple logo appears, and exactly after the apple logo, I faced a circle with a line in the middle, and nothing happens (you can see in the attached photo).
What can I do to fix this? And for which reason, it happened.
And also, in the area that comes when I press and hold command+R, I can't connect my MacBook to wifi. How can I fix this problem?
