@osito71, please update your profile (personal details) with your Motherboard, CPU and iGPU or Graphics Card(s).
If you have a prebuilt computer enter make and model instead of motherboard.
If you have multiple systems add them to your signature or build signature.

BreBo : done

I have my Z620 running just one thing to finish : the sound
Another thing that I realise is that if I made the mojave installation and passing my data from my Time machine it was impossible to boot so I made a clean install and everything went smooth.
