If you've opted for recommended kexts caching through /L/E rather than kext injection, yes.

Make sure you use the latest versions of Lilu + AppleALC + CodecCommander kexts and that your audio is configured as per the recommended settings (layout).

Why don't you try as per the guide to see if it works better? This being said, I'm starting to have doubts about that specific model of DW1820A that carries subsystem id 1028:0023. There are now several people experiencing issues with that model. I have 2 x DW1820A carrying subsystem id 1028:0021 and these work 100% Ok in my Latitude 7490. I'm yet to test them in my Toshiba. According to wikidevi, there are 3 x different models of DW1820A carrying a same vend/dev id 14e4:43a3 but each carrying a different subsystem id: 1028:0021 -> tested Ok with 2 x different cards 1028:0022 -> not encountered yet, not tested 1028:0023 -> mostly bad feedback (several people reporting 5-10mins Ok, then system freeze). May be worth trying to inject subsystem-id 21000000 DATA to fake 1st model.

Must be a USB issue: there's no Bluetooth module listed in your SysProfiler. What's the reason for disabling the renaming of EHCx devices to EH0x devices in your Clover config?

I've indeed reproduced the issue; I'm using an external USB mouse most of the time so I did not get that message and never realised the TouchPad does not work during installation; can't say if it's an issue of kexts injection because I've tried to boot my Mojave installation with injected kexts, having deleted all add-on kexts from /L/E and rebuilt the cache, and TouchPad worked Ok. If you can use an external mouse, you'll be Ok.

Go to you account icon at top of Web page and select "My Attachments". You'll get the complete list from where you can lookup the largest ones. You can then click on the link to reach the posts that contains them from where you'll be able to edit the post and remove the attachments.

Free up your attachment space by removing some of your old and large items. You may also save space by minimising the size if stuff you attach such as Clover config folder by removing all the non-necessary data like the Themes subfolder for instance. Attaching very large raw 4K pictures is also taking up space unnecessarily (and totally useless), so resize them to like 800x600 before attaching them. By following those common sense recommendations, you'll save a lot of space.

Are you sure you're injecting kext from EFI/Clover/kexts/other and not caching from /L/E? If FakeSMC is in /L/E, Clover will not inject kexts.

Ok, so the Lenovo 04X6020 is E key and your slot was A+E Key. Good to know you were able to use it after cutting a notch in the card's connector.

I'll add that AW-CB210NF/BCM4356 to the list of unsupported cards.

Weird... It would appear I had placed the wrong I2C kexts in my pack #4. Probably a mistake when I was testing and recompiling various versions. I've corrected this in new pack #5. My apologies.

No, of course it's the same Alps I2C TouchPad fitted to my 7490. Can't see any reason why the I2C kexts available in my posted Clover pack would not work on yours the same way they work on mine. Double check your USB installer.

See "7490 BIOS settings" thread at top of this Latitude 7000 Series section

It's all to do with the I2C drivers... A Magic TrackPad will of course work perfectly, it's an Apple acessory! You really can't compare the 2 x devices when one is an Apple product and the other a PC piece of hardware that's not even meant to be supported and relies on goodwill development.

You may try the I2C kexts that are available in my Latitude 7490 guide. Got them from another thread but I already forgot which one! Oups...

If you already cache FakeSMC from /L/E, that's normal. You need to understand how Clover kext injection works in relation to FakeSMC. Anyway, it's recommended to install add-on kexts in /L/E and cache, rather than inject them from E/C/k/O at boot time.

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:

Use the revised pack I posted in the guide. It's got better I2C kexts which fully support the TouchPad, except the buttons. I've just tested USB-c WD15 docking station and it's supported near-100%. I only have 1920x1080 external displays though so cannot comment on 4k.

Looking good at my end!

No, you can install a fresh version over your existing one without needing to remove anything. That method will actually retain all your apps and data.

No, you'd have to have the system fully running under Clover for that.

Regarding loss of boot, try and re-install Enoch on your El Capitan partition. You may also try to boot without cache, provided your kexts were copied to /Extra/Extensions. You'll need the following boot flags and boot options for that: -f -v KernelBooter_kexts=Yes If you're running Enoch and wish to retain it, you have no choice but make up a new USB installer with the macOS version of your choice and install the new version over your El Capitan partition. The E6230 perfectly supports Mojave so don't hesitate. You'll just have to switch to Clover.

USB keyboard and mouse normally work OOB. Maybe you replaced or removed the default vanilla drivers.

No patched DSDT in the uploaded debug package Mario.
