I can no longer maintain this repository, mainly due to lack of time and hardware switch. Thank you everyone who helped me by contributing to this repository.
You may encounter a keyboard mapping issue where your tilde key (~/`) is wrongly mapped to (§/±). The solution is simple, you can remap the key using native MacOS commands as follows:
hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000064,"HIDKeyboardModifierMappingDst":0x700000035}]}'
If this problem is resolved in the next release, you can remove any remappings back to initial just pass an empty array:
hidutil property --set '{"UserKeyMapping":[]}'

Auto remap keys every time you log in
- Start Automator.app;
- Select "Application";
- Click "Show library" in the toolbar (if hidden);
- Add "Run shell script" (from the Actions/Utilities);
- Copy-and-paste the following script into the window:
hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000064,"HIDKeyboardModifierMappingDst":0x700000035}]}'
- Test it;
- Save it somewhere: a file called your_name.app will be created);
- Depending your MacOSX version:
- Old versions: Go to System Preferences → Accounts → Login items, or
- New version: Go to System Preferences → Users and Groups → Login items (top right);
- Add this newly-created app;

Create the USB
Follow the guide on the OpenCore documentation to create a USB for installation. Choose the operating system you use to create the USB and proceed with the guide. At the end of the Create USB section, OpenCore will ask us to do additional configurations. We don't need to do any of that because the EFI folder in this repository provides all necessary configurations we need for installation on Dell Latitude E7470.
Boot and Install macOS
- Plug in the USB we created to your Dell computer
- Press the Power button to turn on our computer (if you used the Dell to create the USB, shutdown the computer first)
- Wait and we will see the Apple icon on a black screen with a progress bar at the bottom
- Then, we will see a menu with four options. Make sure select
Disk Utilityto partition your disk appropriately and format the partition for installing macOS intoAPFS. If you are dual booting with other operating systems, an easier way would be to partition the drive beforehand as some formats like NTFS are readonly on macOS. - Follow the installation steps and configure the preferences to your liking
- Log in to macOS and enjoy
Booting without USB
You need to plug in the installation USB created previously everytime you start macOS after shutdown. If you want to boot without the USB, follow this guide by OpenCore.
Update Instructions
-
To Update to Big Sur from Catalina, just replace the previous Catalina EFI(only if you're using it from my repo) with this one and update normally.
-
To update from an older version of EFI to the current one, download this repository and replace your EFI folder with this one. Make sure you use your own SMBIOS, the included one is only for reference.
-
After update, you can check your current OpenCore version by typing the following line in the Terminal:
nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:opencore-version
You may see a line printed as follows:
4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:opencore-version REL-074-2021-09-19
where REL means a RELEASE version of OC, 074 means version 0.7.4, and 2021-09-19 is the date of the release.
Fixing iServices
-
In order to get Apple Services like App Store working, you need to generate your own SMBIOS(The included one is only for reference).
-
For more information on how to do that, visit the Dortania Guide.
Update OpenCore and Kexts
Follow this guide to automatically update OpenCore and all kexts to the latest version.
Do NOT upgrade the
IntelBluetoothFirmware.kextandIntelBluetoothInjector.kext. The newest version does NOT work on Latitude E7470.
I clipped the relevant parts of the guide here for reference: Thanks to OCAT, updating and maintaining OpenCore basically boils the update process down to 3 major steps: Synchronizing the config.plist, Updating OpenCore and Drivers, Updating Kexts and Resources. That's it.
Terminal - To find out which version of OpenCore you are currently using, enter: nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:opencore-version
- ProperTree and a plist Editor. I use a combination of ProperTree for creating snapshots of and PlistEditPro for editing the config.plist. There's also the free open-source, cross-platform PlistEDPlus
- Kext Updater - One of the must-have tools for maintaining your EFI Folder. It can mount the ESP Partition, download OpenCore, Clover, Drivers, Kexts and NVIDIA Webdrivers. It also has useful Tools integrated, like creating backups of your EFI Folder, Rebuild Kext Cache, Disable Gatekeeper, compare and validate config plists and calculate ScanPolicy. It is a tremendous time saver for maintaining your EFI Folder. For Kext Updater to work properly you need to disable SIP.
- OCAT (OpenCore Auxiliary Tools) - Tool for editing and updating OpenCore files, Drivers and the config.plist. Its best feature is that it automatically updates any outdated config.plist to the latest structure and feature-set without changing your settings: like adding, renaming, removing or relocating entries. So no more manual editing of the config structure is required to bring it up to date, which was a tremendous p.i.t.a before.
CAUTION: When updating from version ≤ 0.6.5, disabling Bootstrap is mandatory prior to updating OpenCore, to avoid issues. Disable BootProtect (set it to None), reboot, reset NVRAM and then update OpenCore. More details here. My suggestion: don't use Bootstrap unless you really have to (for example, if you have Windows and macOS installed on the same disk, like Laptops often do).
CAUTION: If you are running macOS older than Big Sur, you need to change the following values, otherwise you won't see your macOS Disk(s) in BootPicker, since the APFS Driver will not be loaded:
UEFI > APFS > MinDate: set it to -1
UEFI > APFS > MinVersion: set it to -1
Updating your system's EFI folder basically works the same as updating a downloaded EFI folder. The only difference is that we store a backup to a USB stick and perform the actual update directly on the mounted ESP. There are less steps to perform overall and the workflow in Kext Updater differs slightly. IMPORTANT: Before you do anything, Backup your working EFI Folder to a FAT32 formatted USB Stick as a fallback to boot from if the system won't boot after updating OpenCore.
- Updating OpenCore, Drivers and config.plist with OCAT
Run OCAT and check for program updates if you haven't already (globe icon)! Mount ESP (Hard Disk Icon) BACKUP YOUR CURRENT EFI FOLDER ON A FAT32 FORMATTED USB STICK! Open the config.plist Next, hit "Save" (the Floppy Icon). This will automatically update the config.plist to the latest form with the latest feature-set. Click "Synchronize OC main program" (aka the Recycle Button). This will update OpenCore and the Drivers present in your EFI.
- Gathering latest Kexts and Resources using Kext Updater
Click on "Check" to download the latest kexts for your EFI. They will be stored in Desktop > Kext-Updates by default Next, click on "Bootloader" From the Drop-down menu, select "OpenCore". Another drop-down menu called "Please select" appears next to it. Select "OcBinaryData" and hit "Download" The Kext Updates Folder on your Desktop now contains the latest Kexts and Resources Copy and replace only present outdated Kext files in the downloaded EFI > OC > Kexts Folder Copy and replace the Resources Folder in the downloaded EFI > OC > Resources (ideally, update HfsPlus.efi as well if you use it - it's in the "Drivers" Folder of "OcBinaryData) Basically, OpenCore, the Config, Drivers, Kexts and Resources are up to Date now. On to validating the config...
- Validate and Test
Open the config again in OCAT and click on the green check mark icon to validate it. Everything should be fine. If it is not, compare your config.plist with the sample.plist in included in the OpenCore Package to fix the errors mentioned in the log. Fix Errors if there any. Once they are fixed, save the config and reboot.
DONE! Congratulations you successfully updated your OpenCore EFI to the latest version!
