Can't be a laptop with nVidia dGPU any more. Apple and nVidia divorced several years ago...

TP-Link published a revised Catalina driver for TL-WN727N v5 in January. Use that. Previous versions probably aren't supported.

It's not a partial EFI, it's the set of Clover files that are applicable to the 7490, the rest being what Clover will install according to the version of Clover you install. The pack therefore comes to complement the Clover version provided in the guide you got the pack from. If your 3490 specs are very close to the those of the 7490, then you may proceed with the same guide and setup, except the DSDT of course.

"nk" terminology refer to horizontal resolutions so "2k" refers to a resolution of 1920x1080, aka "Full HD". If your monitor is "2k", 1080p will be the best you can get. 2560x1440/1440p is "2.5k"... You've activated WEG boot parameter -cdfon but I see no enable-hdmi20 property injection in your Clover config. I would suggest you add that, I believe it's expected. If 1440p resolution remains natively unsupported/unavailable, try SwitchResX app.

I doubt it has anything to do with the kexts used for USB ports multiplexing. OP has added a couple of patches for USB to his Clover config (on top of the totally unnecessary AppleIntelCPUPM patch for Sandy/Ivy Bridge...). I would recommend to: remove those USB patches return to USBInjectAll and cache all kexts from /L/E after cache has been rebuilt and system rebooted, run Hackintool to regenerate SSDT-UIAC table + USBPorts kext and stick to what our guides recommend of course...

DW1707/AR9565 is part of those natively unsupported Atheros cards that have poor or limited support with a specially re-written Atheros40 kext. You can search about it, it's been quite substantially discussed and documented over the years, here or at InsanelyMac. Bottom line is that you'd be well advised to bin that card and replace it by a fully supported model such as the DW1560 or DW1820A. Or stick to your Mediatek MT7601 USB adapter if it works.

7490 pack contains 3 x main kexts related to keyboard/touchpad: 2 x I2C kexts with PlugIns + 1 x PS2 kext with PlugIns.

What you ask is partially incorrect so don't expect much of an answer. Once simply does not "generate" or "create" a DSDT per sé. One extracts the ACPI table from BIOS through whatever method/tools, this usually in order to consult its contents and/or patch it. With regards to SSDTs, specific SSDT tables can indeed be generated as a much cleaner and more efficient alternative to DSDT patching. It's the trend that's been followed these very last few years. If you want to engage in this, you really have to know about ACPI coding and it's for advanced programmers because it's very low-level and tied to hardware. So, if you don't even understand the basics, it's not for you yet. To give you a few pointers, though you probably won't understand much of it, look into the tables that have been posted in recent Mojave/Catalina guides for recent platforms (SKL, KBL, CFL). You'll see such things as very-specific/very-targeted SSDT tables. Now, of course, if you had specified the computer model your request refers to and the extracted set of BIOS tables, you might get more in terms of an answer. Nothing has changed on that respect in the last 4 or 5 years...

Is the entire Touchpad not functional or just the buttons? No solution to date for those but TouchPad is definitely working with the PS2 kexts available in the pack posted in my 7490 guide. Sometimes not functional until a few reboots. All in all, sounds like you simply encounter what we all do...

Folks, do take this into account re: Catalina and later... https://osxlatitude.com/forums/topic/12385-how-do-i-unlock-catalinas-protected-file-system/

If you search for this, you'll probably only find stories of failures; afaik, that card is not supported.

Sounds more like a dirty keyboard... Get it cleaned up.

Nope, GeForce 940MX is Maxwell, so it's dead in the water (on top of the well-known lack of support for Optimus) ...

After 25pages on the topic, It's time to consider that all matters related to getting DW1820A and other BCM4350 cards fully operational have now been exhausted. Given that here is nothing new to discuss and that all information related to configuring a Hack to get DW1820A/BCM4350's Wireless + BT functional is readily available, this thread is now closed and archived.

Please consult our Guides section which answers this surprising 1st question. You can then decide which Latitude generation best matches your own compatibility criteria.

It's limited to 1st post of threads. Very annoying but we've no fix for this yet...

@Pierre C., can you please NOT quote every message you reply to? Thank you. With regards to updating the kext with firmware, Rehabman has provided full details on his repo and it's also mentioned in previous pages of this thread. Look it up.

What you call "a different type of slot" is called M.2 (NGFF) and that's all the E7270 takes: M.2 cards; I very much doubt you'd be able to fit an adapter + mini-PCIe card in it due to lack of space. That pretty much answers your previous question about models... We have covered supported/compatible M.2 cards at great length in our Wireless forum section. Go for a 2230 DW1560 or DW1820A (DW1830 is 3030 and 3 x antennas).

Please consult our FAQ section on the matter.

We provide no bootpack for those E6x20 laptops for Mojave and/or Catalina. High Sierra is the last macOS version to be natively supported on the Sandy Bridge E6x20 series. There is no proper support for the nVidia Fermi GPU beyond El Capitan and no native support for HD3000 beyond High Sierra. Although there are tricks to run Mojave and Catalina on unsupported HD3000 platforms, these are increasingly cumbersome to install and you'll have hell each time you'll try to update. My advice is to stick to High Sierra or change your laptop if you want to run Catalina.

Above link died a long time ago. Dumps can now be found here.

Unfortunately, most new members go straight for requesting support without reading forum rules or the FAQ section...

Please consult our Wireless & Bluetooth section where you'll find all you need re: DW1820A.

It's perfectly normal, that's the way it is; you're just not fully familiar with macOS upgrades/updates.
