I installed Catalina 10.15.4 on the nvme Drive on Windows 10 with the help of your EFI
1. First I changed windows installation from MBR to GPT
2. Then created Partition 50GB for Catalina
3. Then increased size of Windows EFI created by default of 100 MB to 200 MB for Catalina
4. Then installed...
know about bios version but while installing Mojave I had to adjust date back to July 2019, so I said. Maybe on only newer models Catalina can be installed.
How to update bios btw z 390 m non gaming.
I manually also checked date in terminal at disk utility but the error showed up, now i am tryig the other EFI
Is it possible that catalina 15.4 having problem with 19,1 smbios ?
UPDATE : it didn't work either. I give up. I better start working on Mojave. Thankyou for your help :)
With this EFI i am able to install Mojave 10.14.6 instead of Catalina Thankyou sir.
Now i have put new ssd then removed every other ssd and then Loaded Optimized Defaults then set BIOS again for install and now I am trying to install Catalina from first EFI
i will let you know which EFI works.
My USB keyboard and mouse not working when using thisefi, how do I install it ?
UPDATE : Without usb and keyboard I let it load and after 1 minutes it gives prohibited sign from Boot macOS Install from Install macOS Catalina.
For one week, about 10 hours daily I m trying to install Catalina 10.15.4
now it is just stuck on second stage around 10 minutes, I see that it creates data folder and older folder but the installer froze, and I had to restart from the beginning.
i9 9900k, Gigabyte Z390 M, kingston 120 ssd, rx 580 10.14.6 Mojave
Except sleep it is working but panics after 6 minutes then freezes sometimes restart, that feels so bad, although if it don't restart it can go on.
Please check the report and help me !!!
I found this working EFI from hit and trial method on this very thread, all patches are somehow the guy has stored in origin folder and not patched.
Also using Aptiomemoryfix is giving me prohobited sign.
