I have used the link that open High Sierra in Mac App Store, but I can’t see it in my App Store, why?
I want to double check with you before I start the update.
I have a new clean SSD 1TB, should I install Sierra on it first?
1 Open the full installer (10.13.6), do the firmware upgrade. I shutdown the computer and start it by holding the finger on the button and releasing it after the sound stops.
2 After the firmware upgrade (10.13.6), installer will open again and I close it.
3 Check if BootROM is MP51.0089.B00, if yes I shutdown and install the Metal capable GPU.
4 Download the full Mojave installer from Mac App Store.
5 Open the installer and do the firmware upgrade. Same as 1.
6 After the reboot I check if BootROM is 140.0.0.0.0.
7 Not sure if this is right. I use a bootable Mojave USB-key and do a clean installation?
Now I have the 18AWG dual mini 6-pin to 8-pin PCI-E Y power cable. Does the cable look right?
RX 580 pulse have HDMI, so it should work to use Apple HDMI to DVI adapter for my second display Cinema HD (old)?
