I´m searching many days but did not a solution.
I am using a iMac 19,2 from 2019.
Normally I use Linux for my daily business.
Now I have tried Haiku on my laptop for a long time and its like… year - I like it
Here is what my problem is:
I create a installation media (tested all things: partition with direct dd of image, live boot from usb, efi boot from external hdd, formated internal hdd with efi partition and tried to boot…)
All the time I try it, I get only a black screen.
I can choose the Haiku EFI-boot via ALT on startup.
After that - nothing.
No logo, no splash - just black.
If I wait about 5 minutes, the iMac simply reboots.
I have tried do blacklist the intel_extreme and many other drivers, without success.
I can´t get in the bootloader with shift or space bar, get only black screen.
I have also installed Haiku from my laptop to external hdd and booted from there same thing.
Also I have installed Haiku via VirtualBox and direct access to the partition on the internal hard drive.
In Virtualbox it boots fine and I can disable all drivers during boot.
But, if I really boot it…
…I must not tell it…
I have currently no idea what to do, because I don´t get any error or some other messages.
Some ideas ?
I have currently installed Linux and can test anything.
Thank you for helping (any sorry for my really bad english )
