I would take that measurement with a grain of salt. According to iStat I'm pulling over 700 watts running heaven, but only 46°C (I'm on water, but still doesn't jive).

It works once you've installed AppleIntelWifi from GitHub. Unfortunately the speed is limited to 140Mbps. It works though. Bluetooth works as well :)

No, just tested it and watched a 2 minute video. Maybe my power play tables are too aggressive? I do have my Vega64 of Water. Try this config. I removed the power play tables. Rename it to config and replace the one in your OC folder.

Look through the thread. Someone posted a spreadsheet that works using the same fundamentals.

Big Sur Custom Logo I made a guide over on the Big Sur Support area of the forum. https://www.tonymacx86.com/threads/custom-system-logo-in-big-sur.306192/

Since you've made it this far. You might as well change your login background. Replace /System/Library/Desktop Pictures/Big Sur Graphic.heic Don't forget to create another snapshot sudo bless --folder ~/Desktop/Logo/back/System/Library/CoreServices --bootefi --create-snapshot

I finally moved over to Big Sur yesterday. I was a bit surprised when the old path of replacing the system logo didn't work. Took me a bit to figure out how to get it to work, but here we are. Process I took. First you'll have to disable secure boot. Boot into Recovery. Open Terminal...

Big Sur OS Logo. Apple has changed how the OS is locked down. Very complicated process to make any changes now. I've got it figured out after having to restore the OS once :lol: Making a tutorial and plan on publishing it on the Big Sur portion of this forum.

Opencore updated to 0.6.3 to support Big Sur in the first post. I've updated and can confirm wifi/bluetooth, etc work. Replacing Assets didn't work with my script. I'll look into to this and try it manually again.

I updated my bios to F12j and they added a toggle to unlock the MSR. So much easier :headbang:

It's in the second post of this thread. Link

If you are using the opencore from my other thread, then you'll have to update ROM. "OPENCORE: You must add your mac address as the ROM in order to get your Messages working." If you are using Clover, make sure your onboard network card isn't disabled in bios.

NOTE: Supplemental update 10.15.6 Before installing, remove EFI-Backups in the root of your drive. The update refused to install, but it also destroyed my ability to boot regularly. I ended up hitting Command+R while selecting my boot disk with the mouse in the OC menu to get into recovery mode...

Not sure why you would have lost sound. Mine is still good. As a precaution, I've updated the first post with the latest OC and kexts. Make sure after you install it to reset your NVRAM and set your ROM (Ethernet Mac Address).

Did you set your ROM to your Network Card MAC Address?

I've sent PM's to other moderators asking why, since early last year when it started happening to every one of my posts (including posts without links). This is the first time I'm getting an answer. Thank you. It's weird that the algorithm pics and chooses when it wants to flag a post though :(

You have to simple google search for Grub. For some reason every time I try to post a link, my post gets flagged and then subsequently deleted without any rhyme or reason, so I've given up on posting links to help people out. I went to CaseySJ's post and the link is indeed still working. Let's...

You haven't unlocked your MSR yet.

Updated to 10.15.6 without issue. So much easier with Open Core. Remember to run the logo script after to restore your Logo.

If you don't know, then it is locked. Unlock it using the procedure I outlined in post #63
