Hi everyone, I want help with this headphone problem that gets stuck and returns to work once the system sleeps. I've tried a lot and couldn't find solutions. Any help would be greatly appreciated I did everything from CodecCommander and alc_fix but to no avail.

Hello all! Here my configuration. Maybe someone will need it. Dell Latitude e7440 (no Fingerprint version) CPU: Haswell Intel Core i7-4600u dual core 4th gen IGPU: Intel Graphics HD 4400 Ram: 16GB DDR3 SSD M-SATA: 256GB Bios: A28 Mac Os: Catalina 10.15.4 Working: full graphics acceleration on Intel HD4400 iGPU, including brightness control (Fn+F3 Brightness up Fn+↓ Brightness up) (with Lilu v1.4.2 + Whatevergreen v1.3.7) multi-display with HDMI audio, including HDMI, (no microphone input) and headset output (with AppleALC v1.4.7 & No Inject audio) GigEthernet LAN connection (with IntelMausiEthernet 2.5.0 kext) wireless and bluetooth with any compatible card (a BCM94352HMB with Airportbrcmfixup.kext v2.0.6, BrcmBluetoothInjector.kext 2.5.1, BrcmFirmwareData.kext 2.2.10, BrcmFirmwareRepo.kext 2.5.1, BrcmPatchRAM3.kext 2.5.1, FakePCIID_Broadcom_WiFi.kext 1.3.15, FakePCIID.kext 1.3.15) All USB ports (3.0) integrated webcam sleep & wake battery management (with ACPIBatteryManager v1.90.1) keyboard and touchpad, max 2 finger multitouch(with VoodooPS2ControllerR6 v6.0.0) SD Card reader Not working: Nothing For Bios settings follow this perfect guide by Hervè (set like this all option that you can find) For create bootable usb/Installation/Post Installation follow this perfect guide by Hervè (just download latest Catalina 10.15.4 from Apple Store) Is better to use the latest clover release, for download it click here You can also follow these steps, starting from the installation of the clover in the usb stick (after the media creation tool process in terminal is done) : Run Clover r51xx.pkg and select USB (Install Mac Os Catalina) as destination Just flag in true on Clover for UEFI booting only, Install Clover in the ESP, UEFI Drivers - Racommended drivers - Install Open terminal and paste: diskutil list Choose your usb EFI partition and type (for example disk1s2): sudo diskutil mount disk1s2 Open Finder and open mounted EFI Replace the EFI folder with this: EFI 10.15.4 e7440 V2.zip Boot from USB and install Mac OS For post-installation repeat the same steps with these differences: Run Clover r51xx.pkg and select your SSD/HHD as destination Just flag in true on Clover for UEFI booting only, Install Clover in the ESP, UEFI Drivers - Recommended drivers - Install Remove all usb sticks and others disk (leave only the target Mac Os disk) and just type : sudo diskutil mount EFI Open Finder and open mounted EFI Replace the EFI folder with the USB EFI Change your serial number in clover configurator SMBIOS section Enjoy your hack!

I would love feedback from those who have installed Yosemite on a Dell Latitude E7440. I used Pokenguyen's guide at the link below to perform an installation on mine: URL: https://osxlatitude.com/index.php?/topic/6461-guide-e7440-with-clover/ The system boots fine using Clover. However, I've observed that the mouse cursor is "jumpy" - and the same can be said for launching applications. Even the first screens of the installation process had sluggish animations and mouse cursor movement. Other times, windows that are closed leave behind "ghosts" of what was being displayed. Eventually the display refreshes to clear these old contents off the screen. The system is using a SSD drive, and would run Windows 7 & 8 very well, as far as response behaviors would go in a completely different environment. It is also using HD4400 for video output. I'm just curious if my description of how things are performing are of no surprise to those that also run this model, in that these behaviors are expected despite the model being able to be used as a Hackintosh. Otherwise, if there are those who have encountered these behaviors, and somehow overcame them, I'd love that input. As for things to try, I'm pondering the value of: 1) Trying out Jake Lo's Yosemite guide for this model, as outlined at: https://osxlatitude.com/index.php?/topic/7478-dell-latitude-e6xxxe7xxx-yosemite-install-guide/ 2) Evaluating if Yosemite is too heavy for this model, and seeing how Mavericks performs by comparison, using steps from Pokenguyen's guide at the top of this post. Folks in this community have so much valuable experience and understandings of how things operate, so I want to thank you in advance for anything you're willing to share with me!

Good day all, I've managed to install Mac OS X Yosemite 10.10.3 on my Dell Latitude E7440. Sound is working. (Actually the volume is a bit on the low side, but still works) Wi-Fi doesn't work at the moment. The main issue I'm having is the Intel HD4400 graphics. When starting up the graphics seems to be ok, but when moving the cursor it seems to lag a bit. Sometimes it starts to flicker a bit. Can someone help me out with it? <key>Graphics</key> <dict> <key>DualLink</key> <integer>0</integer> <key>Inject</key> <dict> <key>ATI</key> <false/> <key>Intel</key> <true/> <key>NVidia</key> <false/> </dict> <key>ig-platform-id</key> <string>0x0a260006</string> </dict>
