kernel panic caused by com.apple.driver.AppleIntelKBLGraphics ( iMac Retina 5K, 27-inch 2019) when upgrading from original OS to any major MacOS
Hello,
I tried to fix my iMac Retina 5K, 27-inch 2019 to bypass this critical kernel panic but without any success. Can you help me to find a solution please.
It happened when I tried to upgrade the original MacOS. The new installed OS keeps rebooting until I press shift, so I can boot in the safe mode.
