CATALINA INSTALLATION STUCK AT APPLE LOGO WITHOUT ANY PROGRESS BAR

[MDee]

Ok I replaced the EFI folder with the one you provided, but I am still seeing that I get stuck at the same exact point when running in verbose mode…

Clear NVRAM before trying to boot ?

I am not sure how to clear the NVRAM, but I understand there is way to do it with Opencore? If yes how do I install Opencore? Thanks.

I am not sure how to clear the NVRAM

At the Clover boot menu press the F11 key.

Ok did that, yet I still see an empty progress bar.

However, I think that the verbose language may have changed slightly…

Attached is a screenshot.

Are you sure your motherboard supports native NVRAM ?

Z270 should have native NVRAM.

trs96, I am not sure…I’m thinking it may not.

Either way, what is the next step my friend?

Bustycat, do you have a solution as well?

Native NVRAM Available?

If you don't know what NVRAM is, according to Wikipedia: Non-volatile random-access memory (NVRAM) is random-access memory that retains its information when power is turned off (non-volatile). This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM)...

This post doesn't mention Gigabyte 200 series boards. You may have to do some research.

trs96, It has DDR RAM, not NVRAM…
