[pre-release] macOS Big Sur

[Alex HQuest]

The Big Sur install/upgrade process truly makes great use of NVME technology. The difference running a system with a NVME and a standard SSD is tremendous. Against a mechanic HDD, it is night and day.

With my setup, Big Sur is running amazingly smooth. At the moment beta 4 is more stable than Catalina

Very true. Big Sur DP4 is surprisingly stable for a beta.

This is normal you have to wait at the end and its reboot 

Big Sur BETA IS  WAIT WAIT WAIT 

It has been rebooted, after waiting 10 - 15 minutes, in Forcing CS_RUNTIME, here there was SSD activity. But after that, after select Preboot volume, I stuck into the previous photo without vsmcgen=1.

Furthermore, Recovery 11.0 Volume is fine, I can boot it.

Cheers.

This is strange, I never see this if passing Forcing CS_RUNTIME the rest is done quickly.

Yes, is very strange, therefore, I asked you, if you can post your EFI folder from your ProBook 6570B, because I don´t know what to do more, and what´s the problem.

Cheers.

Thank you, I will try it.

Cheers

Edit : I have the same problem with your EFI, as I imagine. So the problem could be by the BIOS version? In my 2570P I have F.73 version.

I found the problem, it was FastBoot, because two weeks ago, I did a BIOS reset, and I forget to disable this feature.

After disabling this, my laptop boots in 1 minute, very quickly.

Thank you.

Cheers.

When I click the Recovery icon, after some time the screen turns dark and the start menu pops up again with the icons, recovery doesn't work.

Does anyone know how to fix this?

 

Thanks,

I read very carefully your guide in GitHub again, and I saw that FastBoot must be disabled, and I remembered that 2 weeks ago I did a BIOS reset, and I supposed that FastBoot comes enabled by default, so I disabled it, and voila. Here is my 2570P´s Desktop.

Cheers.

ACPI, IGPU, Audio, Ethernet, Sleep are working. WiFi not because I have an Atheros AR9280, I don´t know if it´s supported on Big Sur, but there is no problem, because my 2570P is connected through Ethernet. Bluetooth and SD Card Reader I didn´t tested it, because I didn´t need it.

Cheers.

Big Sur B4 is stable. But in part is because was missing many Unix executable from libraries like dylib files and cache from dyld folders. Many Frameworks was inative, and this is cause stable, because ARM files are presente in /System/Library/dyld on Beta 4.

Efectively the Fast boot activate its not working
You can see here some people enable Atheros wifi but for me I use a BCM compatible

How can I run Windows 10, without ACPI BIOS ERROR, because when I select Windows 10 from OpenCore, it gives me a Blue Screen, I read that is for the DSDT.aml, but how to bypass.

If your windows is UEFI that's not a problem, I boot Windows UEFI without issue with OpenCore

It will likely work; if it doesn't, try this on a command prompt: open macappstores://itunes.apple.com/app/id1497794093

Thanks.  Is there a way to check what version of the installer/OS-beta has been downloaded using this method....?
