I updated to the latest EFI in github and all is well. I'm pleased to see that the caps lock key is remappable in software now, without the need for an SSDT hack. I did have the trackpad stop working after a couple of hours. I have the T450 synaptics trackpad. A reboot fixes it. The trackpad...

Yes. Either go to 2.36 which has a flaw where the whitelist isn't enforced, or upgrade to a newer BIOS with the whitelist removed (you'll need BIOS programming hardware for this). This I don't know from memory, but it's probably correct. I have a DW1820A and it's a hassle to keep the...

I have the same "issue": aftermarket LCD which requires CSM. I assume it probably needs more glue/init code between boot in CSM mode and driver loading to make the OSX driver happy. Since it's cosmetic only, it doesn't bother me :)

Oh wow. That sucks. I'm glad you were able to recover without too much trouble. I have done this in the past without problems (or benefits) in the Clover days and haven't touched it since. Maybe the OC config doesn't tolerate it?

Have you seen the clover t440s guide?

The latest EFI works well for me. Everything functions with just the minimal changes (ROM, MLB, UUID, etc) to config.plist. My maybe-not-normal featureset: filevault, dw1820a wireless, synaptics t430 touchpad. The louder speaker output is nice. Headphones plugging and unplugging and auto...

Right alt mapping to Left alt gives up the ability to remap the key. On my Korean keyboard, the right alt key is marked with 한/영 which would typically toggle language selection. I used to map it to "next source in input menu". I started using PrtSc (mapped to F13) for this thinking it was just a...

Ah, just that when I compare the text of the two with diff -u, there are large amounts of differences that are just newlines, like this: @@ -113,15 +105,11 @@ <key>Enabled</key> <false/>...

I downloaded and booted the latest EFI zip and made minimal changes: - SSDT-DW1820A set to true - added brcmfx-country=#a (this makes my 5GHz wifi behave properly) - replaced SSDT-KBD with my own caps lock->ctrl mapping one - added my serial and other IDs (side note: the config.plist diff is...

dw1820a wireless: in a post in the t440p opencore thread @karnadi had success patching the pci-disable-aspm into the dsdt vs overriding in config.plist. This works for my T440s, and the easily reproducible hang from wake is fixed. Attached is an AML to stick in OC/ACPI which will get sleep...

Thanks for this. The same DSDT setting for the dw1820a works for pci-aspm-default on the T440s :)

You can read the broken bios and attempt to put together something that will work. Step #1 is grabbing an image of the contents of your broken bios chip. After that you can experiment with replacing pieces to revive it. Without knowing what's broken, you can maybe get by with clobbering the...

I recommend getting it working on a thumb drive, then moving it to the disk when you're comfortable. You can leave clover around and flip between the two if you'd like. I sit grub in front of both of them, but you could use the builtin bios picker by adding entries with bootoption (or efibootmgr...

Ah, you're seeing it too?! I thought it might be something specific to my card :/ Does disabling aspm cure it for you? Can you get pci-aspm-default=0 to apply to the BRCM device in OpenCore?

I'll add a little cautionary tale to this bios mod encouragement ... I swapped in a new i7 mainboard, so I read the bios, modded it, and wrote it back. It booted up OK, I hopped into Linux to redo the boot options and poke around to make sure everything worked. No problem. I buttoned it up...
