I saw huge performance boost going from HS to Mojave, its a lot more polished, countless bug fixes, Im not too sure about nvidia cards in mojave though, I’ve heard apple hasnt let nvidia release drivers yet, I may be wrong.With 10.14.3 just out, pondering if I should upgrade. Is it stable? Will it slow down my machine?
GTX 770 should be OK. The Mojave installer complain about no METAL GPU?Might be a good idea but I couldn't get Mohave to install with a non EFI GTX 770. If your 780 was flashed to be EFI compatible there might be a chance it would work, as Mojave has built-in support for the GTX 780M that's in Late 2013 iMacs.
Were you already on the 126.96.36.199.0 or 188.8.131.52.0 firmware (BootROM), or were you on something before MP51.089.B00? There are EFI GPU requirements getting to MP51.089.B00 (and for previous). MP51.089.B00 is basically a requirement before proceeding to Mojave install.Yep it didn't like the 2 GB GTX 770, no Metal card detected, had to switch in my old EVGA GTX 680 Mac Edition.
Curious as to the "huge performance boost" you saw and in which areas. Anything you did not like?I saw huge performance boost going from HS to Mojave, its a lot more polished, countless bug fixes...
Curious as to your rational.Might be a good idea...
How was your experience?I upgraded to Mojave with a flashed 780.
Where did you get the rom for your GTX?I upgraded to Mojave with a flashed 780. I believe an unflashed may also work. Be aware that the 680/780 require an upgrade to Mojave from an existing OS. ie you can’t make a usb installer and use it to clean install Mojave. I found this out after wiping my original drive lol.
