There is no CPU power management through DSDT patching for this SkyLake/Kaby Lake laptop; all is done through your Clover config which is mostly appropriate though you should not require to drop the SSDT tables as shown in your screenshot of p1. Plenty of threads on the matter which include references to tools for monitoring. Look this up, it's off-topic here.

Good news on the BCM4350 front! Further to recent additional findings, BCM4350-based cards such as the DW1820A are now fully supported. Follow our guide, inject the appropriate properties into DSDT or bootloader configuration and off you go. No need to patch kexts or anything of the sort. The closest it comes to working OOB... Full 802.11ac speed (867Mbps) + BT 4.1 all supported! These cards come as a great supplement to existing M.2 supported models such as DW1560 and DW1830. View full article

Just follow the many guides available on the forum on this matter. In a nutshell, boot with USBInjectAll then run Hackintool to generate (or regenerate) your USBPorts kext or SSDT-UAIC table. Then you only either USBPorts or USBInjectAll + SSDT-UAIC. Look it up.

Not a DW1820A issue but a USB one; you need to review your current setup to get all your USB ports working, including the internal one(s).

Clearly not, stick with stuff that works...

No, as I suspected, it's a USB-related issue under macOS affecting the USB internal ports. I guess your definition file/table is not 100% correct. By the way, your Clover folder shows only a "config copy.plist" and it cannot be properly opened with Clover Configurator. I guess it is corrupt/invalid somewhere. Can't comment on the real config.plist file (assuming there is one) but that could be the source of the problem too.

Wifi availability/operation depends entirely on the card you use. So begin by stating the make and model of device then lookup our FAQ section + wireless cards inventories for all eventual guidance... Ethernet should work once you configure your BIOS according to the required settings and install (or inject) the kext available in the (numerous) E7440 packs...

Please detail the config you use for your DW1820A (Clover properties injection + eventual kexts) and specify the card's part number/subsystem id. How do you turn the card off and back on? Keyboard (soft) button or macOS own controls? No such issue with the DW1820A I use in my Latitude 7490 but only the macOS controls work (not the soft button). Same behaviour with the other BCM4350 cards I have. With regards to wireless, DW1820A and other BCM4350 cards should require no kexts; too many people keep using kexts to make their card appear as Airport or whatever but it really is not required. Things should be kept simple! Talking of simple, what drives you to turn off the wireless then back on again?

Please simply use the "Reply" box/button; there is no need to quote every single message you directly reply to.

Such details are listed in the OS X/macOS section if you cared to search a little.

You'll have to identify that SD card reader (make, model, PCI ids) in order for compatibility can be assessed. Most USB-based readers work OOB (but not all) but it's a very different story with PCIe models, which require a kext. Many Realtek devices aren't supported.

And check your BIOS settings in case Bluetooth is disabled there too.

I'm not sure Win10 can be booted off USB in such a way. Google For booting Win10 off USB and follow what you find. This more a Windows issue than a Hackintosh one...

Given the positive feedback following recent announcement re: ASPM parameter it appears that DW1820A/BCM4350 cards can now be considered fully operational throughout. As such, this thread is closed, pending archiving by end of January.

More a USB issue than a Bluetooth one...

There's really nothing to fear but it's a closed matter then.

@denkteich, Bottom lines say it all, don't they?

What you mentioned above was obviously the number PCIe channels/lanes available on the M.2 NVME slot. I've not checked the E7270 though I'd be surprised if Dell had fitted a 2 x lanes B+M M.2 slot for SSDs but check it out. All I can say is that the same was said about the 7480 and 7490 and it turned out to be false. Those do have a 4 x lanes B+M M.2 slot for SSDs and I was able to verify that a Samsung 960 EVO ran perfectly at full speed. https://osxlatitude.com/forums/topic/8431-ssd-benchmark-results/?do=findComment&comment=93924 You can also look at sites such as Crucial and/or others where you'll find PCIe x4 NMVE SSD being offered for the E7270. Eg: https://www.drivesolutions.com/cgi/shop/ug2store.cgi?command=listitems&kind=dll&pos=0&type=itemid&itemid=dll354

Well, if you want to lift all possible doubts, contact Samsung support directly.

Of course, why wouldn'it it be compatible with the E7270?

Try and boot in single-user mode, then manually rebuild your cache.

Make sure you use the latest kext's version (available off Rehabman's own repo) and that you install it with the correct permissions in /L/E before you attempt to rebuilt your cache.

Issue unresolved to date. Clear explanations detailed here: https://osxlatitude.com/forums/topic/9049-m4800-why-does-not-lucky-at-all-m4800-not-all-are-built-the-same/ LVDS screen + nVidia = Ok EDP screen + nVidia = NOk.

Open up your Clover config in Clover Configurator app and you'll see immediately.
