Catalina(10.15.5), Opencore(5.8), Dell Inspiron 5447, SLEEP & Trackpad/keyboard?


  • CPU: Intel Core i5-4210U
  • GPU: Intel HD Graphics 4400
  • RAM: 8gb DDR3
  • Motherboard/Laptop model: Dell Inspiron 5447
  • Audio Codec: ALC255/ALC3234
  • Ethernet Card: Realtek Ethernet
  • Wifi/BT Card: BCM94360NG
  • What guide/tool followed:
  • What part I got an issue with: Trackpad and keyboard don't work after waking from sleep
  • What files/config I am using: Here is my EFI folder minus SMBIOS info
  • Extra Info: Everything works except this one issue with the sleep. After the laptop goes to sleep, it doesn't seem to wake from keyboard or trackpad, so I push the power button. After it wakes from sleep, the trackpad and keyboard don't work. Has anyone had this problem before? It would be super to be able to walk away from the laptop instead of turning it off.

USB Mapping help

USB Mapping help

Hey hackers,

Post-install troubleshooting my fully functional Hac (except for sidecar) - OC 0.5.8 - Catalina 10.15.5 with smbios MacPro 7,1.

Want to finalize this build with USB mapping. After going through the guide- I have done the following:

  • USBInjectAll under both EFI/OC/Kexts and config.plist -> Kernel -> Add
  • config.plist -> Kernel -> Quirks -> XhciPortLimit -> True
  • config.plist -> ACPI -> Patch -> EHCI and XHCI ACPI renames (did not do due to MacPro7,1)
  • identified the following usb ports through Hackintool and attaching usb 2.0 and 3.0 devices.
    • Is it possible I'm missing some USBs? And by this I mean, is there a chance even with plugging in usb into all known ports that I am still not identifying some internal ones (i.e. like the wifi and aura ones?)

Is it possible to upgrade from 10.15.4 to 10.15.5 with a 5700XT/Navi?

I'm running into what seems to a known issue of a crash on the second restart of the 10.15.4 to 10.15.5 upgrade. I'm using a 5700XT as my main card and I'm not using RadeonBoost.kext

My Specs are:

Intel i9600k Gigabyte Z390 Aorus Pro Gigabyte Titan Ridge Thunderbolt Card MSI Gaming X 5700XT Opencore 0.58

I've seen threads where people run into the same issues as me:

I've also seen at least one comment of someone with a 5700XT upgrading without issue:

Apparently this is a fairly well known issue but it definitely took me a bit of searching to find even that one failure post.

So is it possible to upgrade at all? Am I missing something obvious?

Hi, I would like to try this raid card on an Asus z370 prime a II with Intel i7-8700. Is it something like this supported? HYPER M.2 X16 CARD V2

It has specific bios entries, but the os will access the drive?

Vanilla/Open-Core guide for Z390 Designare?

I'm getting ready to build a hackintosh with this motherboard. While the tonymacx86 guides are quite comprehensive, I'm wondering if a cleaner vanilla guide exists anywhere else? The tonymac stuff uses quite a bit of their custom tooling and patched files and it's a lot to sift through...

VDA on RX580

I just discovered my computer has a problem. When using boot-arg "shikigva = 128 and shiki-id = Mac-7BA5B2D9E42DDD94" to turn on acceleration for vga rx580, the GB5 score is 31k. While not using the other two boot-args, the GB5 score is 46k, and of course it will lose acceleration.

How should I handle this problem? if you can turn on full acceleration and the GB5 score is not too much difference (up to more than 10k points), it is still great.

I’m using SMBIOS iMac19,1 | i5-9400F | RX 580 | b365m asrock pg4

My first try with OC Hackintosh...

My first try with OC Hackintosh...


I have 2+ years experience with Hackintosh, having built one using Clover. After the Mojave update and loss of support for NVIDIA graphics I put the project on hiatus for 1 year.

After finding this Reddit and Open Core I decided to start from scratch.

I followed the instructions from the Vanilla OC Desktop Guide
The EFI Partition on my install USB thumbdrive looks like this:

When I start the installation from the USB thumbdrive this shows up:

Then this:

And the process stops right there. Anyone else has had this problem? Is there a file I am missing in my EFI/OC folders?

My machine's specs:
CPU: Intel Core i5 6500 @ 3.20GHz (Skylake)
RAM: 16.0GB
Motherboard: Gigabyte Technology Co. Ltd. Z170X-Gaming 5
Graphics: 4GB NVIDIA GeForce GTX 1050 Ti (soon to be replaced by a 8GB Radeon RX580)

Thanks in advance.

And, apologies if this post falls outside rules.

X99 Success with Mojave, failure installing Catalina

Hardware/Software used:

  • Asrock Fatality X99m Killer motherboard
  • Intel® Core™ i7-5820K CPU
  • Sapphire Pulse RX580 8GB GPU
  • Samsung EVO 850 SSD 250GB
  • Samsung S24B150 1080p LCD Display
  • Opencore 0.5.8 bootloader.
  • P3.50 BIOS

Initially, I tried installing Catalina(10.15.4) on the above system, but could never get it to install. I had trouble with the initial install because it would hang in the middle of the apple logo while loading the installer, then once it finally loaded neither of the ethernet interfaces would come up. Once i forced an interface to come up and got the first part of the OS installed, the second part would hang on the Country picker( you could scroll through the list of Countries but could not select continue).

After giving up on Catalina I tried installing Mojave, and had the exact opposite experience. It just installed and ran without any issues. I installed several programs, and they all ran fine, watched youtube videos without any problem. I'm very happy with the Mojave install.

Four days later I boot MacOS and it fails with the Prohibited symbol on the screen. Several reboots all withe the same results. I boot with the installer USB, run disk utility to check the disk and it comes up clean. I reinstalled via TimeMachine and everything is working again.

I guess time will tell whether or not this disk failure will be a recurring theme.

One odd thing I've noticed is that my boot device list in my UEFI BIOS/Firmware keeps growing. Everytime I reboot, a new copy of partition 1 of the MacOS disk is added to the boot device list.

Any comments or advice are welcome. Thank you.

Random glitches and lag


This seems to be a persistent issue for quite some time, and I assume it's something ACPI related but I haven't been able to isolate the issue. Symptoms appear randomly from time to time (i.e. once every couple of minutes) and include:

- Mouse suddenly moving faster and without any precision

- Audio drops or artifacts (I have an USB audio card)

- In rare cases, very small video glitches

System Specs:

  • Motherboard: Gigabyte GA-H87-D3H
  • CPU: Intel i7 4770k
  • GPU: Radeon RX580

The config, ACPI and everything else can be found here:

Any idea what could cause issues like these ?

Opencore 10.15.4 installer auto updating to 10.15.5??


I had a fully working hackintosh-


Opencore Catalina 10.15.4

  • CPU: i3 8100
  • GPU: UHD 630
  • RAM: 8gb 2666 DDR4 Ram
  • Motherboard: B360 WIFI Gigabyte

Me being silly i accidentally updated to 10.15.5 as soon as it came out (yeah i know i'm a noob) and as expected it broke and stopped working.

So i decided to reinstall back to 10.15.4 with what i knew was a 100% working USB to install it on but for some reason it didnt work.

After days of pulling my hair out installing countless different versions changing kexts etc i finally got the system booted without UHD 630 (running at 7mb) i checked the version and it's 10.15.5 so for some reason it is auto updating to the latest version even though im using a 10.15.4 install. Is there a way around this i am very new to hackintoshing but even after countless hours of research i still cant find the solution.

Hoping someone can help me out on this one it's driving my crazy.

Thanks in advance!
