Computer is reborn to a new life - still in 2019;
with latest apps and fast running :-)

What doesn't work:

AirPort card is not recognized after installation;
some models has a Broadcom wireless chipset build in -
and therefore ->

What was done to make it work:

1. From the menu, run Administration -> Driver Manager
2. Select the "bcmwl-kernel-source" drive
3. Apply changes
4. reboot
AirPort Extreme is recognized and working now :-)

Additional notes:

Boot Manager is recommended and in use
