Hi,

I have an issue with my laptop. It goes to sleep, but the power button is not glowing. When I press it it wakes up - the keyboard lights up, but the screen stays dark until I press a key on the keyboard, then I see the login screen. Sometimes the screen stays dark and I have to power down the laptop. Here are my hardware specs:

DELL XPS 9550 15151

Chipset: Skylake

RAM: 16GB DDR4

CPU: Intel® Core i7-6700HQ CPU @ 2.60GHz

Video: Intel HD Graphics 530

macOS Catalina 10.15.4

I am attaching my DSDT. Will be very grateful if someone can help me.

Best regards and stay safe.

Wow!!! Jake you are the man. Thank you so much. It worked with DSDT.aml + SSDT-xx. Haven't tried DSDT-slice.aml to see if it works too. I am super happy now. Everything works - sleep, wake, restart, shut down, battery, etc.

Hi Hervé,

I did a fresh install of High Sierra following Jake's guide and using the correct bootpack for Optimus configuration. Now the system boots with video only when I enable Optimus is the BIOS. When I restart or shutdown somehow Optimus is disabled in the BIOS and I have to enable it again in order to boot with video. Also, when in sleep mode, when I press the power button to wake the laptop it directly shuts down. Besides those issues everything else seems to work fine. I know that DSDT is unique for each system, that's why I have extracted my original tables (F4 in Clover). I am attaching my current config.plist, original tables and current DSDT file. I'd greatly appreciate it if you could help me patch my DSDT. Thank you in advance.

Turns out my LCD died, that's why there is no image. I am replacing it and will do a brand new installation with the correct bootpack.

OK. The question now is how to unbrick the laptop?

Yes. I used Jake Lo's guide. I used E6420_HD3000_A23 bootpack and DSDT for high res. My BIOS version was A26.

I used the SSDT that was in the bootpack. The about this Mac was showing only the Intel HD3000.

Hi everyone,

I have a really wired problem with my Latitude E6420. I was able to install High Sierra on it as per the guide and bootpacks offered here. The system has Optimus - NVIDIA NVS4200 and Intel HD3000. The installation was using Intel graphics. Everything was working great until the system went to sleep in High Sierra. The power button was pulsating, which was ok, indicating that the system is in sleep mode. I pressed the power button and the system started to wake up - the hdd light was flashing and I could see the backlight of the LCD, but nothing was showing up on the screen. I waited a little more to see if anything will show - but nothing. Then I pressed the power button to turn off the system. It did, but after starting it up again there was nothing on the screen - no image whatsoever. No DELL logo, no BIOS - nothing. Is it possible that High Sierra has done something? Wrote something bad in the BIOS or whatever? Can somebody help with this problem? Any ideas will be greatly appreciated. Thanks in advance.

Best regards.

Hi,

@OSX64, I am trying to install High Sierra using the Orlarila build but I can't get the installer to work. Can you share how did you do it? Thanks in advance.

Jake Lo, is this a vanilla installation? I want to have an installation which is as close as possible to a real mac.

Hi all,

Can someone help me create a proper config.plist for LATITUDE E5450?

Here are the specs:

CPU: Core i7 – 5600U @ 2.6 GHz

RAM: 16 GB DDR3

HDD: 256 SSD GB

Display: 14 inch

Res: 1920×1080

Video: Intel HD5500

Other: Camera; HDMI; USB 3.0;

I'm looking for the Lion bootpack for D520. It's not on the bootpack download page. Where can I get it from?

Best regards,

Djuby

Thank you. It makes sense not to pursue this idea any further.

Hi all,

I need some assistance in getting OSX installed on Dell Vostro 1220. I know there is no bootpack available for that specific model. I tried myHack vanilla way but so far no luck. Chipset is Intel GM45 with integrated video. I'm not sure if Mavericks will work on that hardware, so Mountain Lion will be fine too. I will support any help available and will try any suggestions. Thank you in advance.

Best regards,

Djuby

How far do you get when you boot off the USB key?

With -v -f flags it gets stuck on "Read HFS+ file: [hd(0,2)]/System/Library/Extensions/AppleHDA.kext/Contents/PlugIns/AppleHDAHardwareConfigDriver.kext/Contents/Info.plist] 14352 bytes."

Djuby

have you tried myhack with a generic extra?

Yes, I've tried it, but can't boot after the installation.

Hi,

Here are the specs:

CPU: 3rd Generation Intel® Core™ i7-3517U processor (4M Cache, up to 3.0 GHz)

Chipset: Intel HM77 Express

RAM: 8GB8 DDR3 SDRAM at 1600MHz

Video: Intel HD 4000 with discrete NVIDIA® GeForce® GT 630M with 1GB GDDR5 VRAM

Audio: Intel High Definition Audio with Waves MaxxAudio4

Let me know if you need anything more.

Hi all,

I've been trying to install OS X ML on a Dell XPS 14 Ultrabook with almost no luck so far, though the XPS 14 Ultrabook is almost identical to Mac Book Pro in terms of hardware. In theory a plain vanilla installation (myHack) should work out of the box, but again, no luck. Is there an EDP and/or a bootpack for that XPS model or any other way to get OS X ML working on that laptop. Any help will be greatly appreciated.

Best regards,

Djuby
