Hi, I have a small problem with my Open core Hackintosh build.
I actually got EFI from someone on the internet and tweaked it a bit so I could get up and running.
Here is my EFI.
My laptop boots fine but while booting, it shows the apple logo for the first 5 seconds, then goes blank for 2-3minutes and then I see apple login screen.
This happens every time. I tried a few config edits but didn't work.
Can someone look into my EFI and suggest any necessary changes that can improve boot times?
I'm transitioning from Clover to Opencore. I thought the process will be simpler but it turns out it isn't. I have created a bootable Catalina USB with Opencore but stuck at this error. I have attached my EFI and the verbose output. Anyone please provide some guidance please?
The laptop is HP Pavilion 15 Gaming:
Intel Core i7-9750H
256GB SSD + 1TB SSD
PS2 Keyboard + I2C Trackpad
Hi, I wanted to transpose my CLOVER installation to OpenCore for future updates.
I followed this guide and after some googling
I've fixed the LOG: EXITBS error (RANDOM SEED like error).
Now I still receiving the IOPCI error (kernel_task kernel panic).
My CLOVER is fully working.
- Backlight and Monitor
- Battery Patch
- Camera and Audio (B&O)
- dGPU GTX 1050 is turned off
On OpenCore I translated everything except the battery (I just need to apply the If statement in ACPI), but I want first to boot on Mac OS using the OpenCore.
In this thread, I have fully documented the installation of macOS Catalina on my HP EliteDesk 800 G4 Mini. It is a PERFECT HackMini8,1 and is running very well for me without any issues. I hope this documentation helps you to install macOS on your hack. Please leave feedback if you think there is anything I can improve and let me know if you have any questions.
This is my first "modern" hack supporting UEFI and my first hack using Clover "on-the-fly" patches. My previous hacks
Laptop: Thinkpad T61 / Nvidia NVS 140m
Laptop: Dell Latitude E6410 / Nvidia G3100m
Desktop: Gigabyte G31 / GeForce 9600
Desktop: Biostar TH55HD / Sapphire Pulse RX580 (Google "Catalina Biostar TH55HD" and look for user name deeveedee)
are all perfectly running Catalina and I patched them all "manually" - all DSDT patches applied with MaciSL with virtually no Clover on-the-fly patching and all booted Legacy Clover. This UEFI hack was MUCH easier and took about 20 hours vs. a combined hundreds of hours for the old hacks. I wanted a hack that was a little more future proof and I think this is it. I hope you enjoy this as much as I am enjoying it. It is a perfect MacMini8,1.

I am really at my wits end here. I am hoping someone on here with more experience with UEFI and boot loaders might be able to provide insight into an otherwise inexplicable problem I am having with a brand-new system built around the ASUS TUF Gaming X570-PLUS. My gut tells me the problem is somehow related to UEFI settings, Secure boot, or some combination, but I really have no idea if that is the case.
The problem is two-fold. First, my system will only boot to a device (e.g., USB stick) under two conditions: 1) no SATA drive is plugged in or 2) when a specific SSD is plugged in (I'll refer to this as SSD1). I have three other hard drives that otherwise work (I have tested them in another system). None of them have Windows installed, though some do have existing data partitions. One of the three is a brand-new, never-been-used 1TB SSD. If I plug in any of these three other hard drives, the system will reboot immediately after POST. However, if SSD1 is plugged in it will boot to a USB stick - UEFI or Legacy, doesn't matter.
Secondly, if I attempt to create a partition, run a surface test, or install an OS to SSD1, the system immediately reboots. I can format SSD1, change volume sizes, run a surface scan, but only in a live linux environment - if I plug SSD1 into another machine as a secondary data drive (i.e., I boot to my primary boot volume), the other machine will blue screen when loading into Windows. If it is attached to this new machine, it will boot to a USB stick just fine.
I have also enabled Hot Plug, which allows me to access SATA drives that I plug in after boot. If I hot plug the brand-new 1TB SSD during a live linux distro, the drive shows up and I can see its properties. However, if I try to do something like create a partition or run a surface test, the machine will also immediately reboot.
Does anyone have any idea as to what might cause this? The only thing that I can think of that explains both problems is some kind of secure boot-like security feature, but I haven't been able to figure out how to confirm whether that is the case. In 20 years of building computers I have never even heard of anything like this. I am new to EFI systems, however, so I'm quite out of my element - this is the first EFI-based system I've set up.
