Horizontal lines over iMac (M1, 2021) 24-inch screen
Hi, so this problem happened around 10 hours ago. These lines also flickers a lot and looks like this.
Steps taken:
- Restart the iMac
- Screen Mirroring (the screen is normal when being mirrored to my Macbook)
- Screen capture (Normal screen image without black lines)
iMac 24″, macOS 26.5
