Hey, nice updates! I've tested this and there are indeed some nice improvements! However, I still encountered an issue with sleep. After sleep, the trackpad doesn't seem to work anymore. Does that feature work for you? The previous EFI did not have issues with that. After doing some research, i found this (https://github.com/VoodooI2C/VoodooI2C/issues/371) and it seems like that's the issue we're having. I was able to fix it by mixing some voodooI2Cxxx files together (The I2CSynaptics version provided in the first EFI did not have issues) and was able to get it working again, with the only issue being the trackpad is a bit weird when waking from sleep. A simple click does fix that tho. That bug was fixed here (https://github.com/VoodooI2C/VoodooI2CSynaptics/commit/804db5c7da71365807555f94e77258f83e57d616) but I'm not able to use this since I was not able to find a version with that patch, but also with working wake from sleep. To fix this, there are a few possibilities: - Find a version with the patch and wake from sleep. ( I wasn't able to search a lot since I don't have a lot of time) - Compile a version with the patch enabled. - Try VoodooRMI VoodooRMI seems to be kinda new and specifically made for synaptics trackpads. I don't know if it's worth to have a look at. Maybe someone who has some spare time can take a look at this? I'll share the slightly modified EFI in case anyone wants to use it. Some other small changes I made are: - Enabled FileVault support (still does work with FileVault disabled) - Updated OpenCanopy resource files to match Big Sur icons. - Added AirportItlwm for native macOS wifi with the built-in Intel wifi card (works surprisingly well, 802.11AC is supported in the newest version and handoff/universal clipboard are working) https://www.icloud.com/iclouddrive/0UEwqR5rIx-Fif6WMhSMMN76Q#EFI Tested on macOS 11.3.1 The EFI was larger than the max file size so I wasn't able to directly upload it here.

I made a guide for it on reddit a few days ago, I'll post it here :). I didn't really test it a lot but I have booted in Windows with CFG lock disabled, and it booted just fine, so yeah, might be worth it! The guide:

Update: I managed to unlock the CFG in the bios. To Samarth, maybe you should consider also doing this and adding it to your guide, as this can provide better stability and proper cpu power management. More info about it here: https://dortania.github.io/OpenCore-Post-Install/misc/msr-lock.html#turning-off-cfg-lock-manually. Note that this method doesn't work on our ideapad, since Lenovo was so kind to lock it all ?. If there's any interest in this I can provide some information on how I've done it (in short: I used a tool called "RU"). It's not that hard but I'd rather have a good nights sleep instead of useless writing if no one will use it.

I also had issues with sleep with the opencore EFI. They're fixed for me by using the voodooTSCSync kext. After that, no more issues with sleep, closing the lid works too. Only "bug" I've found with it is that the trackpad state isn't quite right when woken up but that's solved with just clicking the trackpad. I remember that was the same with my old clover catalina efi. Also, thanks Samarth for the efi! Works almost perfectly, I just had to remove some things since my laptop doesn't have a dGPU. The only bugs I have left on big sur are the wifi, which I have to look into that kinda new kext thing, and the trackpad that stutters when the laptop's on battery. I had that on my previous catalina clover efi too and afaik I fixed that somehow so here that might work too!
