OpenCore really is for advanced users and requires very precise settings. If you or your friend are not advanced users, I'd recommend you stick to Clover for its long-established stability, wide use and the extensive expertise throughout the Hackintosh community.
Installing Catalina with Clover on a Haswell desktop platform with a Radeon RX570 graphics card should be a no brainer. It can even be done before the discrete graphics card is delivered given that Desktop HD4600 is fully supported.
And now it is me that solved my sleep problem, exchanging the Bluetooth/Wifi combo, with the Fenvi T - 919, again, and voilá sleep works perfectly, wake with the mouse and more importantly don't crashes and I haven't to force shutdown and reboot...
Some tips and observations concerning DP installion to an available APFS HDD container/partition.
Assumes an existing working ESP bootloader.
1. Go ahead and make your USB installer with OC 0.6.0 or later, but if you have an existing install of Catalina you can save time by starting the Big Sur installer directly from Catalina, choosing the target partition, and letting the installer copy over the install files rather than waiting on USB to boot and copy. You can then use the USB installer to reboot Big Sur as required to complete the installation.
2. If you are a linux multi-booter and using grub2 as your main bootloader, and if you have an existing Catalina install with a working chainloaded OC or Clover, suggest you don't disturb/break your existing bootloader by making tweaks for Big Sur. You can make an additional small 200MB FAT32 partition on your HDD and put your Big Sur bootloader there and chainload it from grub.cfg. Run lsblk -f or sudo blockid from linux terminal and note the UUID of the Big Sur FAT32 bootloader partition you made. Temporarily edit your boot grub.cfg and add the following entry where xxxx-xxxx is your Big Sur FAT32 bootloader partition UUID:
for open core:
search --no-floppy --set=root --fs-uuid xxxx-xxxx
chainloader /EFI/OC/OpenCore.efi # or whatever path you use
or for clover:
search --no-floppy --set=root --fs-uuid xxxx-xxxx
chainloader /EFI/CLOVER/CLOVERX64.efi # or whatever path you use
This way you can easily edit/tweak your Big Sur bootloader settings without breaking your existing working ESP bootloader. If you are not confortable using an XML editor to edit config.plist, and you have Catalina installed, you can download ProperTree from github and use it from Catalina. Later you can modify your linux /etc/grub.d/40_custom to include any custom bootloader menuentries you want to keep, and then run update-grub.
3. When your install is finished and you are finally at the working desktop, you may want to make a backup. With Catalina this was easily done by using Disk Utility from a bootable USB installer to restore to an APFS formatted backup media. The Big Sur DP4 installer Disk Utility has repeatedly failed to replicate Big Sur and it appears Disk Utility from Catalina 10.15.6 can not perform this task with Big Sur APFS containers. You can, however, clone the entire Big Sur container to removable media with third party software. Alternatively, and depending on the size of your AFPS container/partition and transfer rate, using dd can take quite a long time to do the backup.
If you clone to USB media and then boot the clone to test the backup on the same computer from which it was made, both the Big Sur USB clone and the Big Sur HDD container installation show up within disk utility, but only in the USB media area.
4. The recovery console for DP4 does not appear to have a language selector that works, but defaults to a mostly non-English type of character based language. The language selector button with drop down menu on the top right does not appear to work.
Despite the language issue, recovery terminal is available.
Mount command does work and you can mount -uw /dev/diskxsy to make the normally read-only volume writable (where x is the number of your Big Sur disk and y is the read-only slice from the mount command output).
Make your changes from the console and reseal (where x is your Big Sur volume name shown with mount command):
bless --folder /Volumes/x/System/Library/CoreServices --bootefi --create-snapshot
5. If you have an existing Catalina installation with brew and numerous brew installed programs such as ntfs-3g, you can directly copy the brew files/programs to the corresponding file system locations within Big Sur and if necessary, manually create the soft links to enable programs. If you need to write to the system file tree in the system snapshot you can do this from the recovery console as previously referenced.
NTFS volumes will normally mount read-only but read-write can be enabled without ntfs-3g and without osxfuse as follows:
From terminal make a mountpoint of your choice for each ntfs volume. Example: sudo mkdir ~/ntfs
Unmount the target read-only ntfs volume where x is disk number and y is slice: sudo umount /dev/diskxsy
Mount ntfs volume as read-write: sudo mount -t ntfs -o rw,auto,nobrowse /dev/diskxsy ~/ntfs
Link to desktop: sudo ln -s ~/ntfs ~/Desktop/whatever_name_you_choose
Make sure finder is configured to show hard disks on the desktop.
Keep in mind that if you use ntfs-3g with osxfuse to automount ntfs volumes, install version 3.11.0 or later of osxfuse. You may have to copy the ntfs-3g mount_ntfs binary directly to /sbin.
Here are some post-install termainal tweaks tested in zsh. If you do not know what they do, don't use them:
defaults write NSGlobalDomain NSDocumentSaveNewDocumentsToCloud -bool false
defaults write com.apple.finder AppleShowAllFiles TRUE
defaults write com.apple.TextEdit RichText -int 0
defaults write com.apple.finder _FXShowPosixPathInTitle -bool YES
sudo defaults write /.Spotlight-V100/VolumeConfiguration Exclusions -array "/Volumes"
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
defaults write com.apple.desktopservices DSDontWriteUSBStores -bool true
defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool true
6. If you have an existing Catalina installation with third party programs they may work without modification by copying them directly from Catalina Applications folder to the Big Sur Applications folder AND copying the corresponding entries for those programs from Catalina ~/Library/Application Support to Big Sur ~/Library/Application Support.
7. System Preferences Trackpad.prefPane does not appear to be working as of DP4. Substituting the Trackpad.prefPane from Catalina also not working.
8. Automator utility can create an apple script or shell script app for Big Sur but it fails with error message when run from the desktop. If you open the app in automator and click the step button the app executes with the desired result. Running the command line directly within the zsh terminal also executes properly.
9. The attached EFI with OC was modified for Skylake/520/Sunrise Point but you may find that it works for a range of models with similar Intel hardware. Supply your own Platforminfo. If you multi-boot with linux you can run lspci -k from terminal in linux to show your pci hardware configuration.
10. If you desire the OC GUI, change the config.plist PickerMode specification from BuiltIn to External, but be aware that all icons may not be completely visible. Change HideAuxiliary to true if you do not want to see recovery.
A big thank you to all who have unselfishly devoted their time, energy and intellect to making Big Sur and previous distros available to those who are looking for alternatives and who are willing to learn.
Here is my Gigabyte Z490 Vision G EFI based on 0.6.1 final release with latest release kexts. It should work with most Z490 Systems. Make sure you use Big Sur Beta 6 and higher. If you want to use this for Catalina, add correct Cpuid1Data and Cpuid1Mask under Open Core's Kernel section.
I have used this theme since I started using cl0ver. So though the years I have updated it accordingly and cause I have not been really active in the InsanelyMac community, as of recent, I figured I would share this for whomever is interested...updated to up to Big Sur and tested on Clover current version (r5122 at time of posting)
I am sure I read a post some pages back - or was it in the Big Sur forum - someone with the same problem and one of the Devs, not sure which one whether it was Vit or Fritz offering a suggestion, sorry man not much help but someone will come to your aid with the solution. Good luck.
If you mean Opencanopy PickerMode=External
If you want to always show ShowPicker=yes
Remember to download fonts/icons from Acidanthera OcBinaryData repository on github and put in the Resources folder in EFI/OC/
You also need opencanopy.efi in /EFI/OC/Drivers/
@BALDY_MAN Take everything into account as said by @ghost8282 plus have a look at the potion of the config.plist I have attached for you to follow also you can swop out your current Resources Folder the one here and you will have the result like the two examples in the pics. Good luck.
I have at last managed to install.11.0 Beta (20A5364e). but I had to make a new EFI File and change to a iMac 20,2
It runs ok but I have a small problem I would like help with. (1) when I boot up in Mac the scrolling script is using large type
(2) I would like to add boot up icons. What settings do I need to change in my config.plist to fix the two problems I have please.
