Revised Clover pack #7:

Patched DSDT of pack #6 was causing system reset. Re-patched raw DSDT from BIOS 1.11.0 to inject support for Fn-F11/Fn-F12 brightness keys (no other patch) and all seems Ok.

Edit: 05 Oct 2019:

Revised Clover pack #8:

Injected HDMI connector type to iGPU FB@1 to recover from a picture issue (like yellow veil) with HDMI output + loss of HDMI audio, all due to default DP connector type on the framebuffer. This worked OOB initially (certainly did with my initial 10.14.4 build) but clearly not any more with subsequent Mojave versions, at least 10.14.6.

Revised Clover pack #9:

Moved patched DSDT out of ACPI/patched folder since it's causing KP for most people. It was only patched to support brightness control through Fn-F11/Fn-F12. Jake Lo has provided SSDT alternatives in other guides/threads so it's best to use that. I'll try them asap on the 7490 and update accordingly.

Hervé · April 16, 2019

I initially installed Mojave on an external USB3.0 HDD in order to avoid messing with the Win10 installation that's on the built-in M.2 SATA SSD. Given that the Latitude 7490 can boot from microSD card (needs Legacy boot enabled in BIOS), I installed Clover and the 7490 pack on an old 2GB microSD card I had lying around. Card was initially reformatted FAT32. I now use it to boot Mojave from a freshly created partition on the SSD without having had to mess around with the Win10 Boot (EFI) partition. It works great.

Hervé · April 25, 2019

I got to test the Dell WD15 USB Type-c docking station today.

Supported OOB:

HDMI, mini-DP and VGA outputs
GigEthernet RJ45 port (Realtek RTL8153 USB3-to-Ethernet converter, 0x0bda:0x8153)
Rear USB2.0 ports
Rear USB3.0 port
Front USB3.0 port
Front headset jack

Unsupported:

Rear line-out jack (tried various layouts to no effect)

Regarding VGA output:

VGA worked OOB as single connected display, laptop booted lid closed.
VGA worked as 2nd display only if connected at startup (it's quite usual for VGA not to work if connected after system has started).
VGA worked alongside DP and/or HDMI but only in clone mode, not as 2nd or 3rd display. This is something apparently done at docking station level. Dell manual states it's the expected mode in 3 x displays setup but, in my case, this was experienced only with DP connected, laptop's lid closed.

Front headset output:

VGA output (lid closed):

DP/HDMI output (lid closed, with or without VGA):

Dual display, built-in LCD + VGA:

Dual display, built-in LCD + DP or built-in LCD + HDMI:

Building on the info provided by @jpz4085 all those months ago, I've patched the Latitude 7490 DSDT in order to remap brightness control to Fn-F11 and Fn-F12 keys (by default, it's Fn-F6 / Fn-b).

ACPI debugging confirmed that Fn-F11 and Fn-F12 controls are handled by Embedded Controller (EC) EV5 event. This was hinted by presence of call to IGPU.BRT6 method under EV5 Method in the DSDT:

    Method (EV5, 2, NotSerialized)
    {
        \_SB.PCI0.IGPU.BRT6 (Arg0, Arg1)
    }

BRT6 Method showed the usual default LCD notifications:

        Method (BRT6, 2, NotSerialized)
        {
            If (LEqual (Arg0, One))
            {
                Notify (LCD, 0x86)
            }
            If (And (Arg0, 0x02))
            {
                Notify (LCD, 0x87)
            }
        }

The required DSDT patch is quite simple and as follows:

1) inject Darwin in PCI0._INI Method:

    Scope (_SB.PCI0)
    {
       [...]
       [...]
       [...]
       Method (_INI, 0, Serialized)  // _INI: Initialize
        {
            [...]
            [...]
            If (CondRefOf (\_OSI))
            {
                [...]
                [...]
                [...]
                If (LOr (_OSI ("Darwin"), _OSI ("Windows 2009")))      // Darwin OS injection
                {
                    Store (0x07D9, OSYS)
                }
                [...]
                [...]
                [...]
         }
    }

2) check for Darwin in OSID Method:

    Scope (_SB)
    {
        [...]
        [...]
        Method (OSID, 0, NotSerialized)
        {
            If (LEqual (ACOS, Zero))
            {
                [...]
                [...]
                If (CondRefOf (\_OSI, Local0))
                {
                    [...]
                    [...]
                    [...]
                    If (LOr (_OSI ("Darwin"), _OSI (WIN7)))     // Darwin OS check
                    {
                        Store (0x80, ACOS)
                    }
                    [...]
                    [...]
                    [...]
                }
                Else
                {
                    [...]
                    [...]
                    [...]
                }
            }
            [...]
        }

3) modify notifications under BRT6 Method:

        Method (BRT6, 2, NotSerialized)
        {
            If (LEqual (Arg0, One))
            {
                Notify (LCD, 0x86)
                Notify (^^LPCB.PS2K, 0x0366)     // Fn-F12 = Brightness up
            }
            If (And (Arg0, 0x02))
            {
                Notify (LCD, 0x85)
                Notify (^^LPCB.PS2K, 0x0365)     // Fn-F11 = Brightness down
            }
        }

Patched DSDT available in the Clover pack posted above.

Revised Clover pack #3:

Moved patched DSDT out of ACPI/patched folder since it's causing KP for most people. It was only patched to support brightness control through Fn-F11/Fn-F12. Jake Lo has provided SSDT alternatives in other guides/threads so it's best to use that. I'll try them asap on the 7490 and update accordingly.

Hervé · September 16, 2020

Following BIOS update to v1.16.0, I revisited the patched DSDT since it was (finally) also causing a reset to me. I dumped all tables from BIOS and came to realise I had applied the brightness keys patch to a Clover pre-patched DSDT!

I therefore re-applied the patch to the raw DSDT. My 7490 now boots Catalina without reset and brightness keys are fully operational. I've also updated the patch code above to return those Clover pre-patched lines to full vanilla code (XOSI returned to _OSI and XSID returned to OSID).

Patched_DSDT_Lat7490_BIOS-1.16.0.aml.zip

I invite Latitude 7490 users to test this revised patched DSDT and feedback to me by PM so that I can update the bootpacks accordingly. In case of issues (system reset), select BIOS.aml DSDT table in Options->ACPI patching->Dsdt name at Clover main boot menu to load the raw DSDT at macOS startup.
