Today i tested the card in a different (Latitude) laptop and it worked flawlessly under both Windows and macOS.
In Mojave it did not require any kext, it was recognized as airport, bluetooth worked fine out of the box as well.
So i don't know what's going on with my Inspiron laptop, seems like this kind of card is not compatible for unknown reason. I'm glad (not really) to hear that my PC is not the only one, otherwise i would have spent hours of useless troubleshooting. I think i'm gonna return my card and try a different type (DW 1560 maybe).

Ok, I gave up using DW1820a. I finally ordered a DW1830 and everything is working like a charme. Although the card has one additional pin for a third antenna I got bluetooth working and also wifi is working without any issues so far. Wifi is working OOB without any kext. Only for Bluetooth the following three recent kexts are needed (in efi/clover/kexts/other)

you didn't have to cover pin 54 and 55 on dw1830 to get wifi and bluetooth working? you didn't add 3rd wifi antenna? Can you verify the card is showing as AirPort Extreme 14E4 in system report / wifi?

Yes you are right. I do not had to cover any pins and I didn't add a 3rd wifi antenna. And it is really working flawless, even Siri is working and listening now (to be honest, I don't know if this is related to the new wifi card).
Let me know if you need further informations.

im only guessing, but I think since you are using Catalina that might be the difference. I noticed your Airport utility is NOT installed, and other airport based services are not available. maybe a Catalina thing

Hi All,

I spent one whole week finally made my touch pad, touch screen, GPU, backlight, and audio working.
However, sleep/wake is still not working, which will ruin all my effort. A laptop that cannot sleep/wake correctly is
not a laptop...:< I went through the thread several time and saw nobody talking about sleep/wake issue.
Hope I am not the only one who has sleep/wake issue. When AC power is connected, my Inspiron 7586 seems to
sleep and wake up well. It can dim backlight automatically and then sleep for hours before being waken up.
However, if AC power is disconnected, it will not wake up correctly. Instead, it reboots after I press any key several
times. I've also tried patching my DSDT with 'Fix _WAK Arg0 v2', 'HPET Fix', 'IRQ Fix', 'RTC Fix', 'Shutdown Fix v2' but
none of them help. It's driving me crazy. Please help me.
The attached file is the report generated by gen_debug.sh for your reference.

Thank you.

Regards,
Steven
I've got this too, it's quite annoying. I have no idea how to fix it. (i7 1080p model).

I have another problem, relating to the backlight. About once in every 3 boots, the maximum brightness will be really low. I then need to reboot the laptop to fix it. Has anyone else been getting this issue?

Try AppleALC with layerout-id=77 (0x4D) then both internal speakers and headphone will be working.
I just tried this, no input or output devices detected.

OK, here I share what I did to make my laptop work. But keep in mind, everything I mention below might only work for
Dell Inspiron 7586. I might not be able to offer any support since I still don't know much details about how they works.
I remember someone said Hackintosh is not for lazy guy. Indeed, I am just a fool that willing to browse tons of hard-to-understand articles and scratch my head doing uncountable number of experiments in the nights. I am not an expert.
So forgive me first if I cannot answer your questions.

Let me start with skipping those creating USB installation disk blah blah things since you can find tons of articles talking about it.

1. Before you get started, make sure you copy one of the config.plist from this thread and make sure you have this ACPI patch:
Fix AsRock Z390 BIOS DSDT Device(RTC)

I've been scratching my head for a whole night trying to figure out why my laptop suddenly stop booting due to NVME assertion failure.... Please see post #28. In my config.plist, I renamed it as 'Fix NVME assertion failure' just in case I
remove it again.

2. It will be very handy if you have a supported USB ethernet adapter on you hand. When you see black screen
playing around UHD 620, sometime it isn't real black screen. You can still control your laptop via remote desktop.
https://www.amazon.com/gp/product/B00ZZ6NW5E/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

3. Once you have installed the system, the first thing you do is enable remote desktop. Combining with the USB ethernet adapter, you can have one more option to try with when you see black screen.

4. Preparing DSDT.dsl. My DSDT.aml dumped by Clover bootloader somehow caused kernel panic.
So I used AIDA64 extreem to write out a DSDT binary.
https://www.aida64.com/products/aida64-extreme
And then following Rehabman's guideline to disassemble the binary.
https://www.tonymacx86.com/threads/guide-patching-laptop-dsdt-ssdts.152573/
By the way, RWeverything somehow hung while writing DSDT.

5. Enabling touchpad, touch screen, backlight, and battery manager:
a. Processing VoodooPS2Controller.kext, VoodooI2C.kext + VoodooI2CHID.kext by following steps in this post:
https://www.tonymacx86.com/threads/guide-acer-swift-5-sf514-53t-whiskey-lake-macos10-14-5.277618/

b. Add these patches to kext patches to config.plist

View attachment 421080

b. Patching DSDT for touchpad/touchscreen and enabling backlight and battery manager. Just follow post #42.
Yes, just that simple. Thanks hacker1024.
https://www.tonymacx86.com/threads/dell-inspiron-7586-i7-8565u-intel-uhd-620.277104/page-5

While you compile the patched DSDT, you might have this error.

View attachment 421009

Simply correct the syntax from

Code:
                    CreateBitField (BUF0, \_SB.PCI0._Y0C._RW, ECRW)  // _RW_: Read-Write Status
                    Store (Zero, ECRW (If (PM0H)
                            {
                                CreateDWordField (BUF0, \_SB.PCI0._Y0D._LEN, F0LN)  // _LEN: Length
                                Store (Zero, F0LN)
                            }))
to
Code:
                    CreateBitField (BUF0, \_SB.PCI0._Y0C._RW, ECRW)  // _RW_: Read-Write Status
                    Store (Zero, ECRW) If (PM0H)
                            {
                                CreateDWordField (BUF0, \_SB.PCI0._Y0D._LEN, F0LN)  // _LEN: Length
                                Store (Zero, F0LN)
                            }
and remove a bunch of 'Zero' that also cause syntax error. Then you should get your DSDT compiled correctly.
Code:
                Zero
                Zero
                Zero
                Zero
                Zero
                Zero
                Zero
                Zero
                Zero
And save the assembled file to EFI/CLOVER/ACPI/patched/DSDT.aml. For Inspiron 7586, the above should all the patching we need for DSDT.

**Update: I reinstalled my laptop and found touchpad not working with the exact same hacks.
Spent a couple hours trying to figure out why and finally it was working again after installing
Displaylink Driver for Mac. I don't know why the driver has something to do with touchpad...
Anyway, the touch pad is working again.



6. Enabling Intel UHD 620 GPU. Follow the guideline here.
https://www.tonymacx86.com/threads/guide-intel-framebuffer-patching-using-whatevergreen.256490/
Or simply copy whatever in my config.plist to see if it works for you or not.
View attachment 421035
By the way, don't rename GFX0 to IGPU or you will need to connect to remote desktop to recover it back.

7. CPU power management. Simply follow Rehabman's guideline.
https://www.tonymacx86.com/threads/guide-native-power-management-for-laptops.175801/
You only need SSDT-XCPM.aml
https://github.com/RehabMan/OS-X-Clover-Laptop-Config

8. Fixing wake up reboot issue. I simply create a SSDT-DIDLE.aml by referencing the two posts and put it to EFI/CLOVER/ACPI/patched.
https://pikeralpha.wordpress.com/2017/01/12/debugging-sleep-issues/
https://github.com/darkhandz/XPS15-9550-Sierra/issues/44

Update: You also need to put these method into DSDT directly or the wakeup reboot issue will come back. I don't know why.
Code:
    // Fix wake up reboot issue

    Scope (\_SB)
    {
        Method (LPS0, 0, NotSerialized)
        {
            Store ("Method \\_SB._LPS0 Called", Debug)
            Return (One)
        }
    }

    Scope (\_GPE)
    {
        Method (LXEN, 0, NotSerialized)
        {
            Store ("Method \\_GPE.LXEN Called", Debug)
            Return (One)
        }
    }

    Scope (\)
    {
       Name (SLTP, Zero)

       Method (_TTS, 1, NotSerialized)
       {
           Store ("Method \\__TTS Called", Debug)
           Store (Arg0, SLTP)
       }
    }

    // end

By the way, you need to short press power button first then press any key to wake up your laptop.

9. Enabling WIFI. Replace the Intel WIFI card with a Broadcom BCM94352Z

10. Enabling HDMI. Read the guideline here or simply copy whatever in my config.plist.
https://www.tonymacx86.com/threads/...ching-guide-hdmi-black-screen-problem.269149/
By the way, I don't know how to use hackintools correctly since it doesn't put every required configs into config.plist.
Sometimes even messed it up. So I manually edit everything in GPU's properties.

11. Enabling Audio card. Download AppleALC.kext and use layout-id=77.
https://github.com/acidanthera/AppleALC
AppleALC supported ALC295/ALC3254 since 1.3.6.

View attachment 421036

I tried all possible layout-id for ALC295. Layout-id=77 (4D) works the best (I think).

12. Disabling discrete graphics card to save power. Follow Rehabman's guideline:
https://www.tonymacx86.com/threads/guide-disabling-discrete-graphics-in-dual-gpu-laptops.163772/
For Inspiron 7586, it seems that we only need to add a line in SSDT-9-OptTabl.dsl (Dumped by Clover bootloader).
Not sure if I patch it correctly. At least it doesn't bring me any issue so far.

Code:
        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            Store (DID1, Index (TLPK, Zero))
            Store (DID2, Index (TLPK, 0x02))
            Store (DID3, Index (TLPK, 0x04))
            Store (DID4, Index (TLPK, 0x06))
            Store (DID5, Index (TLPK, 0x08))
            Store (DID6, Index (TLPK, 0x0A))
            Store (DID7, Index (TLPK, 0x0C))
            Store (DID2, Index (TLPK, 0x0E))
            Store (DID1, Index (TLPK, 0x0F))
            Store (DID2, Index (TLPK, 0x11))
            Store (DID3, Index (TLPK, 0x12))
            Store (DID2, Index (TLPK, 0x14))
            Store (DID4, Index (TLPK, 0x15))
            Store (DID2, Index (TLPK, 0x17))
            Store (DID5, Index (TLPK, 0x18))
            Store (DID2, Index (TLPK, 0x1A))
            Store (DID6, Index (TLPK, 0x1B))
            Store (DID2, Index (TLPK, 0x1D))
            Store (DID7, Index (TLPK, 0x1E))
            // Added to turn nvidia off
            \_SB.PCI0.RP05.PEGP._OFF()
        }
12. SSDT hotpatch. I just added some of Rehabman's SSDT hotpatches for run since I don't have the knowledge about how ACPI works...
https://github.com/RehabMan/OS-X-Clover-Laptop-Config/tree/master/hotpatch
By the way, SSDT-XOSI.dsl somehow makes my laptop hard-to-wakeup. So I removed it.

I finally made it works after a sleepless week. That's all I got. I hope it will save some of your time.

Thanks, this is a great consolidation of all the random helpful stuff throughout this thread. I'm trying the sleep fixes, hopefully they'll work!
One thing to add - after a recent UEFI update, my ACPI files stopped compiling properly in MaciASL. Setting the iASL version to 5.1 helped, but I was still getting a random premature end of file error (even though I counted the amout of braces, and the number of opening and closing braces were equal). I had to recompile it with iasl in a terminal, and that worked perfectly.
