I recently installed Catalina using the guide from this website. Almost everything works but I noticed some issues. I wasn't sure if I should create three separate threads or keep everything in one. I decided for the latter.

Here are the issues:

- Disconnecting the laptop from the power source makes it freeze. It needs a hard reboot.

- Despite Bluetooth being available and discovering my bluetooth devices, it is not able to connect to them. As a side note, the WiFi is working perfectly.

- Despite installing Karabiner-Elements, whenever I press the F11 or F12 keys, the laptop would freeze. It needs a hard reboot.

- Connecting laptop to an external display via HDMI works well, when unplugging it the laptop would freeze. It needs a hard reboot.

 

I attached the debug file.

Thanks for your help.

My BIOS setting had "Legacy Option ROMs" enabled, I disabled it.

I replaced the files from from you bootpack into /EFI/Clover.

UPDATE:

VirtualSMC has been the latest release. Battery indicator had been at 100%.
