I installed the latest "macOS Monterey 12.3" and this weird error "Volume Hash Mismatch. macOS should be reinstalled on this mac". Also the macOS restarts randomly. Please provide the resolution for the same if your time permits. Thank you so much. Kudos to you.

Could you give me some guide? Thanks!

Hi,
I've got the 1080p touch-screen version of the E7250. Is there a kext to enable touch screen on the hackintosh?

Hey @SkyrilHD, I need a piece of advice: have you tested Big Sur on this laptop with clover ?
Thanks in advance, cheers.

Hi @SkyrilHD
I'm pretty close to finish hackintosh on my latitude, i just need know how i can will do the fix on Wi-fi connection in Intel Wifi Card.

thanks in advance!!

Hi,
I have installed Catalina with your EFI and it's working all fine, but trackpad gestures aren't working. Is there any fix?

Hello, guys! Luckily i managed to partition my hard drive and install Big Sur. Everything works amazing except the wireless which i've read that is disabled by default. As the title says i am a complete noob and i have no idea how to enable it :( Shall i use OpenCore Configurator or something else? Thank you in advance! Keep up the great work!

I'm using Big Sur and everything works fine, was wondering if there's a way to get the fingerprint reader working? Or is this not possible?

Hello sir @SkyrilHD i want to thanks to you for all your hard works.. I really appreciate it. But after i used monterey hackintosh on my e7250 5300u.. I realize last night when my battery go for 6% it still and it won't to charge the batteries. The battery before install this hackintosh can last for more than 3h. But suddenly cant charge. I go for bios menu battery condition is in good level.. But on monterey it shows to service battery.

Thanks for your attention..

Hey, I just got a 1080p touch display to upgrade my 768p model. Display looks good and touch works in Windows and Ubuntu, but isn't working in Monterey after enabling the Voodooi2c kexts. Looking to troubleshoot, but not exactly sure where to start.

The relevant facts:

• This display came as a fully assembled top laptop panel which was listed on ebay as being from an e7250. I had no reason to doubt this before, but I'm wondering now if the seller got the model number wrong and this is from a different dell laptop of the same size and similar build. It's definitely compatible with the hardware of the laptop itself, I'm just wondering if maybe it's using a different interface or something than the stock e7250 touch display and that's why it's not working.
• The outside casing of the display itself is different from my stock 768p display. The original was a solid matte black, but this 1080p replacement has a subtle checkerboard pattern. Can anyone who has the e7250 with a stock 1080p touch display confirm whether that's normal or if mine may be from a different model?
• Further detail of this panel assembly that may help identify whether it's from an e7250 or not: the inner display surface is a glossy screen which extends above and below the display itself to encompass the camera area and Dell logo. The glossy screen extends to form nearly the entire bezel, reaching to the top and side edges, and coming to an end about half an inch from the bottom of the assembly with rounded bottom corners.

What i've tried so far:

• Enabling the Voodoo kexts that came with this repo. Voodooinput from Voodoops2 disabled and the one from Voodooi2c enabled. No luck.
• I also tried using the latest release of Voodooi2c; I figure these are the same files as in this repo based on that one having been released back in february, but I tried em anyways. I even included the VoodooI2CAtmelMXT, as I think that's the brand of digitizer included in some other dell laptops, but I also had no luck with that configuration.

All that being said, I'll drop an ioreg if anybody has the time to look at it; I've always been not quite sure what I'm looking for when I open IOregistryexplorer so any help is appreciated. Will also reboot to windows shortly and attach a DSDT. If there's anything else I can provide or check to help figure this out, please let me know! Thanks for your time.

Hi @SkyrilHD , I need your help. Those days I have tried to restore my dell-hack that has got right now Big Sur running wit OC without any issues but I wanna give it to my dad so I need to restore it and downgrade to 10.14 .
The problem comes right now, because when I select from the BIOS the USB containing the Mojave Installer and the right EFI (obviously the one for Clover) the pc runs it and later got stuck in a sort of apple boot logo screen but the progress bar doesn't seem to show up at any time. I will attach a picture right below in order to explain better my situation.
Have you got any advice ?
Cheers, Luca.

Hi,,
Thanks for your amazing work,
I got issue with Microsoft Excel, always show error "There isn't enough memory to complete this action", I use Last update of MS. Office, my memory 8GB,
In BigSur can work fine.

Thanks a lot for EFI

Please help
Dell E7250 Trackpad(shows searching for bluetooth trackpad) & battery status not working in Sierra.

I upgraded to Ventura via OTA. Found out that HDMI is not working. Haven't patched GPU acceleration yet. Please guide.

Hi,

I want to install macOS BigSur on my E7250 as well. Same hardware specification as yours.
Booting from the USB into the macOS installer works fine, but I can only select the USB drive and not the internal ssd.

Do I need a specific BIOS version or BIOS settings?

Best regards,
Gino

So I tried troubleshooting according to the dortania guide and the sleep on this EFI is non functional and when it works Bluetooth crashed and the trackpad stopped working.

Hi, I followed everything and tried loading the USB but it says Re-Install instead of Install.
When I click re-install, it says it needs internet to install MacOS.
I'm lost now.

Hi,
I have installed successfully macOS Catalina and it's working fine, but I have found that hdmi doesen't work because when i plug in an external monitor i have a black screen on the laptop monitor and the external doesen't found ani signal. To restore the laptop I have to reboot it because if I unplug the hdmi it still has a black screen. Any fix?

The current issue I am having is very weird... With the current config which is downloadable in 11.0 branch, the kext for the Trackpad doesn't get loaded.

My current try is to re-do the config from scratch again (which I already did) and see if the trackpad will work again.

Here is a quick log of the VoodooPS2 kext:

I think, with the implementation of UTB Map and the USB Tool Box, the WWAN Card ist not seen anymore. could that be?

Hello I am pretty new to hackintosh and got everything to work except dual monitors.

I am on macOS monterey with laptop HP 15-dw2xxx.

This is my current config file:
config.plist.zip

Actually bluetooth and wifi at first also did not work but I fixed it using a wifi and bluetooth usb which now works fine.

My display settings window does not even show the display arrangement tab, just the tab for the main display to change scaling.

I tried to follow this guide but it was too complex for me and too time consuming.

Does anyone know a fix? Just comment if you need more information.

Touch screen is no longer working on the latest Bootloader, tried using the previous version one booting from USB EFI and it worked.

What my Ventura is only installablr with Ethernet? Can you plis tell me why? I want Install with WiFi

I'd like to propose an addition to your repo. By default, your EFI detects macOS and Windows installations/drives. Would you consider adding Linux support too, through OpenLinuxBoot.efi and ext4_x64.efi?

I've been using these in addition to your EFI and they work great (once I figured out that you actually need grub installed for OpenLinuxBoot to detect things). No config changes were needed; simply adding the two files to the Drivers directory and snapshotting in ProperTree made linux autodetection work in OpenCore & OpenCanopy.

Before I got into hackintoshing (this most recent time), my bootloader of choice was rEFInd, which I think is a common choice for people wanting a single graphical EFI boot manager that shows all of their OSes through smart autodetection. OpenCore + OpenCanopy + OpenLinuxBoot is a pretty solid drop-in replacement for that, while also supporting macOS, so I think supporting that configuration is a laudable goal.

That said, do you think this is a worthy addition to the repo? I don't want to push you to make it more bloated if that's your concern, but I think it would make a more well-rounded OOTB bootloader setup for people who want a drag-and-drop solution. I look forward to hearing your thoughts on the matter. Thanks for your work as always.

So, this bug happens on Clover and OpenCore...

Sleep works fine on battery if nothing is connected (USB). But as soon as the charger is plugged in or any USB is connected sleep will not work.

Extracting the logs shows this:

2020-05-07 18:05:57 +0200 DarkWake DarkWake from Normal Sleep [CDN] : due to LID0/ Using BATT (Charge:36%) 6 secs
2020-05-07 18:06:10 +0200 Wake Wake from Normal Sleep [CDNVA] : due to LID0/Lid Open Using BATT (Charge:36%)

Any help is appreciated.

Hello, I have a problem with the EFI that you have given us... I don't understand how to enable bluetooth on the Intel card (the AC7265) one!
I have successfully made into catalina desktop but can't enable the bluetooth =(
Pls help me =)

At first, thank you for this great project, it was really helpful and i appreciate the work you put into it. I installed MacOS on my DELL but Intel Wifi drops to 1-2 Mbps sometimes, so i baught the DW1820a card. I disabled the Airportltlwm.kext, IntelBluetoothFirmware.kext and IntelBluetoothInjector.kext. I added the requiered kext following this guide osy/HaC-Mini#91 (comment) and eddited config.plist but my DELL gets stuck at Mac OS loading screen at around 50%.

Kernel Panic with AppleHDA and AppleALC

It caused to a non booting macOS... RIP

It isn't about the EFI, but how many hour that your laptop use without charge? I'm using the E7450 and it's around 2 hours of battery life On System Information, it said my battery full capacity is 3954mah.

Battery indicator is not showing realtime updates. It suddenly drops from suppose 80% to 10% which causes inconvenience.
You can find the screenshot attached below. At this point of time the battery is removed but still it is showing charging.
Please address the issue if possible. Thanks for the fully working mac os and keeping it updated all the time. Kudos to you.

In the folder there are 2 kext referring to bluetooth.
Could you tell me which one should I enable?

hi

thank you for this .. I installed Catalina using opencore & i was pulling my hair out to get the touchpad to work.

if i use your EFI folder (OpenCOre), my wifi doesnt work, but touchpad works fine.

i had success with OpenIntelWireless/itlwm though with your VooDoops2 kext & touchpad works too. The speed is pathetic but it works.

My WiFi module is Intel(R) Dual Band Wireless AC 7265, REV=0x210

I tried adding the itlwm kext to your EFI, but it still doesnt work. Any help will be appreciated

PS: I'm new to hackintosh

hi,
I created the boot drive, substituted the EFI folder in the EFI volume with yours, and boot up. The boot starts but the page shows the only grey color and the Clover green logo...no options.
What can be?
thanks

I got random issue trackpad doesn't work after restart,

I just updated the BigSur to 11.6 and found that the wifi is not working. Cannot toggle wifi/bluetooth on or off. Used proper tree to activate all the kexts by using OC Spapshot option. I don't know if i am doing anything wrong.

Hi! i tried to install macos with this EFI on my latitude 7250 laptop, but the ethernet wont work, i downloaded other kext-s but dont work.... If i try to install macos "An internet connection is requed to install Macos"

Hey @SkyrilHD, sorry If I disturb you once again, you know that I've recently passed to open core but I've found a little bit of a problem: simply the ethernet doesn't wanna work.
Do you have any ideas on how to fix this matter ?
PS: I will attach a video where you can see the lights popping in the back but the ethernet still don't wanna work.

Hi, I recently hackintoshed my e7250 using this repo as a base, and I love it! Everything's working perfectly in macOS Monterey. This is a Windows issue, so I'm not especially expecting to have it addressed, more just wondering if anybody else has noticed it and might have ideas for a fix.

My issue is that now, when booting Windows 11 through OpenCore (0.8.0) with this configuration, the screen is initially dimmed on startup. Specifically, the screen seems to use my bios brightness settings (100% on AC, 70% on batt) throughout the boot process as expected; but then when Windows enters the GUI and shows the lock/login screen, brightness is set to very dim--I would guess about 10%. This is instantly corrected when modifying the brightness: pressing either brightness key brings brightness back to expected levels, seemingly automatically bumping brightness to the last value used during boot before adjusting it.

The issue only occurs when booting through OpenCore. If I use the uefi boot selector to directly boot the Windows boot manager, bypassing OpenCore, everything works normally. So it's a minor issue that I can easily work around, but it compels me, and if possible I'd like to be able to just use OpenCore as my sole boot manager for macOS, Windows, and Linux (as I do on my other hackintosh, a desktop).

This is something I've never seen Windows do before, and google wasn't especially helpful in troubleshooting it. Theories I have that might be starting points to figuring this out:

• Maybe I changed something in the config.plist that caused this?
  • I don't think this is the case, as I just now re-downloaded the config.plist from this repo and booted it nearly as provided; the only modification is my generated smbios/rom/etc.
• Maybe my smbios is the problem?
  • When I generated my smbios, I used MacBook10,1 (no reason in particular, the e7250 just seems like an entry level compact laptop to me so I picked the closest MacBook I could find in terms of hardware as a base. If others are using MacBookPro12,1 as in the supplied plist and not having this issue, maybe that's the cause.
• Is it Windows 11-specific or specific to the drivers Windows Update installs?
  • I only have an installer lying around for 11, so I haven't tested to see if 10 reproduces this issue on my hardware, but I have tried reinstalling 11 from scratch and the issue starts happening upon the first reboot after Windows is fully installed. It doesn't happen during any of the reboots during the windows install, though, so it seems to be caused by a driver or driver configuration that is installed (probably by Windows Update) during the final installation stage... or by some other code that only gets executed when the login screen is shown.
• Something else?

Again, I'm not expecting this to get fixed and you can close the issue if it's not appropriate, but if anyone has any ideas for isolating or fixing the problem, I'm happy to work to figure it out. Thanks for your time and thanks for this repo!
