Yes, do that first, then make the changes needed and save them before the install.OK. I checked the bios version. it is 2.15
latest bios is 2.75.
Do I still need to update bios?
I recently tested one of these. Installed Mojave with a Unibeast 9.0 drive and used the HD4600 graphics. Worked with no problems. Make sure to uninstall your 1050 Ti before trying to install Mojave.
If you want to use your 1050 Ti right now then install High Sierra instead. Then install the 10.13.6 Nvidia Web driver post install.
