Hi, Finally I finished the installation of 10.14.6 on my Dell E5440. Everything works just fine, but HDMI will not work. Every time I plug it in, it causes a grey screen on my laptop monitor. Also on boot up. I attached my EFI Folder, maybe someone can help me. I searched a bit and read something about Azul Framebuffer Kext. Thank you for helping. Greedings, Hugo EFI EFI.zip

Hi @Jake Lo On reboot, the Bluetooth device needs to be removed and reconnected to get it to work again. Is there something that can be fixed here?

Hi All, I am new here and after struggling for over 16 hours, I finally managed to install MAC OS 10.14.6 on my Dell E5540. A big THANK You to all the members in the forum who helped me get this far. Bluetooth, WiFi, Sound, and Display working!! I am stuck with the last piece, my HDMI port is not working. Connecting HDMI cable makes the laptop display go black and my monitor doesn't detect any signal. From this point, there is no way to recover the display and I need to do a force reboot. I would like to use a monitor in my setup as the laptop display is not that great. Can someone please help me in layman terms? Sorry for my lack of knowledge on this matter. Appreciate help on this.
