Hello. I had a perfect running system with macOS 10.11 for almost 6 months. Today I upgraded to Sierra and it ruined all my setup. One kernel panic after another, Sierra is just not ready yet. Long story short: I need to work with that computer in Windows tommorow, thats why I install Windows 7 on it now. I have two problems now:
1, I have a installation disk and I installed macOS 10.11 succesfully two times with it. Now, when I start to boot is it gives me a kernel panic. Why??
2, Is there any way I can keep my now installed Windows 7 as a Dualboot to my tommorow installed macOS 10.11?
3, If no: How can I install macOS 10.11 and Windows 7 and what partitions and bootloader settings do I have to make for that?
Thanks for response and feedback.
Have a nice day!
