20s is about the best one can get. If you want to enable trim, please note that there is no real need for a patch since Apple introduced a command to enable it as of Yosemite 10.10.4: sudo trimforce enable

Why don't you post a zipped copy of your EFI folder? Things to look at: list of injected kexts SMBIOS and FF/FFM in Config.plist ACPI patches in Config.plist

Ok, these are good. So if you look into your IOREG, we see that your AR5B195 card (168c,2b) is attached to PCIe device PXSX, itself under RP04. This is the device to look for in the DSDT for patching. To patch the device, simply insert the DSM method into the device as follows: Device (PXSX) { Name (_ADR, Zero) // _ADR: Address Method (_PRW, 0, NotSerialized) // _PRW: Power Resources for Wake { Return (GPRW (0x69, 0x04)) } Method (_DSM, 4, NotSerialized) // Device Specific Method for the wireless card { Store (Package () { "model", Buffer (0x1E) { "Atheros AR5B195 b/g/n Wireless" }, "device_type", Buffer (0x08) { "AirPort" }, "built-in", Buffer (One) { 0x00 }, "name", Buffer (0x10) { "AirPort Extreme" }, "AAPL,slot-name", Buffer (0x09) { "Internal" }, "compatible", // Declares compatibility with a device Buffer (0x0B) { "pci168c,30" // PCI id of device supported OOB } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } } Recompile the DSDT and save the resulting DSDT.aml file for re-use. Please note that the "compatible" statement is what's really required here, the rest is purely cosmetic for the SysProfiler information. I attach the patched table where I also renamed RP04.PXSX to RP04.ARPT. Remember to re-instate the vanilla Atheros kext! Repatched_DSDT.aml.zip

I don't know about that app. If you want me to patch your DSDT, post: a zipped copy of your DSDT a zipped output of IORegistryExplorer

Just how do you patch the Atheros kext? As posted and detailed here, the AR5B95/AR9285 DSDT patch is much simpler and will not require any subsequent kext patching, whether at new OS installation or after updates. If you prefer, the Info.plist kext patch can also be implemented through Clover. Personally, I prefer the DSDT one.

Everytime you update High Sierra, you need to reboot the "install macOS HighSierra from..." partition to complete the update. I've seen this across the board.

Sinetek's driver is worth trying apparently: http://www.insanelymac.com/forum/topic/321080-sineteks-driver-for-realtek-rtsx-sdhc-card-readers/page-1

BIOS: F.38 CPU: Intel Skylake QuadCore i7-6700HQ @2.6GHz Chipset: Series 100/C230 RAM: 8GB Graphics: Intel HD530 + nVidia GeForce GTX 960M Audio: ? LAN: Realtek RTL8168 GigEthernet Wireless: Intel AC-7265 Card Reader: Realtek 522A (PCIe) USB: 3.0 Touchpad: Synaptics Intel wireless is unsupported. It'll have to be replace by something compatible, whether through an internal card or a USB dongle. https://osxlatitude.com/index.php?/topic/8696-is-my-wireless-card-compatible-with-os-x/ For the rest, you should be Ok: RTL8168 GigEthernet: https://github.com/RehabMan/OS-X-Realtek-Network or http://www.insanelymac.com/forum/topic/287161-new-driver-for-realtek-rtl8111 Audio: you'll have to install VoodooHDA + AppleHDADisabler kexts then run DPCIManager app to identify the audio codec. Only then may you remove those 2 x kexts and apply the eventual AppleHDA patch. TouchPad: see https://osxlatitude.com/index.php?/topic/1948-elan-focaltech-and-synaptics-smart-touchpad-driver-mac-os-x/ Card reader: should work with Sinetek's early driver according to http://www.insanelymac.com/forum/topic/321080-sineteks-driver-for-realtek-rtsx-sdhc-card-readers/page-1. You would apparently need to install the kext in /S/L/E. A newer version still is in progress. Failing that, look for a recent version of VoodooSDHC kext, if that exists: https://www.hackintosh-forum.de/index.php/Thread/28992-VoodooSDHC-ist-zurück/

Always better to install add-on kexts to /L/E rather than /S/L/E; helps keep track of the kexts and the folder is ignored if you boot without cache (very useful when you tests kexts through injection rather than caching). Only install kexts to /S/L/E if absolutely necessary (like patched AppleHDA for instance).

So same AppleHDA patch as detailed in the E6230 Sierra guide then: DSDT HDEF patch for layout 12 IDT dummy kext AppleHDA patch (Clover on-the-fly or direct binary mod)

Let's say that I've had issues booting HighSierra USB installer set with GUID scheme, not when they were set with MBR scheme.

It's stated in Dr Hurt's thread that you need to replace the TrackPad panel by an older version (Maverick's I think). The file is in the thread.

Finger tapping is something you configure in the Trackpad preference panel...

As explained here, it's not a very good card re: compatibility with Apple's OS. You should have opted for another model. If you want 802.11ac wireless speed, opt for DW1550 or AW-CE123H. If you're happy with 802.11n services, there are plenty to choose from in that inventory... You may also want to consider a real Apple card like the BCM94360CD with an adapter. These work OOB and for all services (wifi, BT, handoff, airdrop). https://osxlatitude.com/index.php?/topic/7554-apple-broadcom-bcm4360cd-80211-ac-wifi-and-bluetooth-combo-card/

Codec id 10EC:0668 is indeed Realtek ALC668.

No issues using the keyboard with one hand whilst moving the mouse with the other on all my Latitude E series with Dr Hurt's Alps driver. But I don't fully understand what you're trying to do!

Easy on the quoting (it really isn't necessary!)... Just how do you install the kext? Describe all steps.

Grab the Alps PS2 kext from the pack of my E6220 Sierra guide here, then report back.

I had assumed Kjescha did read the guide and added all required modules as per the instructions...

How did you arrive to this? Try and temporarily install VoodooHDA (+ AppleHDADisabler) then run DPCIManager again. That should list the detected codec. Your CPU is an i7-4510U @2.00GHz (Turbo to 3.10GHz), right? NB: Since you appear to have a HiRes screen, please only post the useful part of screenshots, not the entire maximized windows where most of them is blank. Contents is then hardly readable, I've had to retouch them. Or reduce windows size to their minimum required... Merci!

Then your E6230 is not tuned properly. Post your entire zipped EFI folder or list & post the zipped set of kexts you might have installed to /L/E or /S/L/E. Audio requires the same AppleHDA patch as usual: DSDT layout injection 12 in HDEF device (you should already have that) IDT 92HD93 dummy kext installation in /L/E (you probably missed that) AppleHDA binary patch (same patch as for Sierra -> see my Enoch Sierra guide for details)

Did you format the USB installer MBR? I'd recommend that. You should then be able to see the "macOS Install from ..." disk partition in the Clover list once the bootloader has loaded.

According to the documentation available on Dell's web site, it's indeed an Alps Touchpad.

Updated for High Sierra.
