macOS Big Sur and Parallels Desktop

How did you create a custom entry to send-key for "t" and "y". I have Y and y in my password and cant login. When I type y and t in username field if trying to reset password they both work so what makes you believe that they are not working? Not doubting your comment, just trying to figure out if my issue is same as I cannot login. When I type my password it goes back to login screen and if I try and reset my password by using my AppleID it doesnt allow my to change it. Both computer password and AppleID password have "y" in them.

I'm also having issues with "1" and "2".
 
Since I was installing into an existing 10.15 drive, I had to covert the drive into a set size, and then boot into 10.15 and use disk utility to resize the drive. That worked. The Big Sur installer let me choose the drive and it's installing now. Sweet!

Ive also found 1 and 2 keys not working. Shift and the key does (same on the t and y).
Very odd bug!

I too have this same issue with the 1 and 2 keys. Except for me pressing SHIFT doesn't get it to work like it does with the t and y keys. I had to press FN to get them to register instead.

Another observation of note. macOS Big Sur says that Parallels has been blocked from loading in System Preferences - Security & Privacy. But when I click Allow and my machine reboots the message remains as if nothing happened. Nonetheless, my VM loaded and ran as expected except for the keyboard issue above.
 
i've also noticed that Parallels hangs every time I try to shut down the app. I have to force quit it every time.
 
I'm also getting the "To complete Parallels Desktop setup, please restart your Mac."
I tried the cmd-r reboot and terminal info listed previously, but that didn't work for me.
Anyone have other work arounds?
 
This is what I found when starting in safe mode, it happens when you try to log in, and then jumps back to the log in screen.

I found this here and fixed my issue.

I was able to get past the "BIErrorDomain error 3" issue in Parallels as follows:

  1. On a real, supported Mac, run this command in Terminal:
Code Block
ioreg -l | grep board-id

2. Make a note of the board ID (mine is Mac-551B86E5744E2388, for example)
3. Run this command in Terminal:
Code Block
sysctl hw.model

4. Make a note of the hardware model (mine is MacBookPro14,3)
5. In the VM configuration, under Hardware -> Boot Order -> Advanced Settings -> Boot flags, enter the following (inserting the information noted above where shown):
Code Block
devices.mac_hw_model="<model>"
devices.smbios.board_id="<board ID>"


That should be enough to allow the installer to proceed.

It's worked.Thx buddy :D
 
This might be a dumb question but, how is everyone creating their install media? Every time I try I get this error:

Code: 
Couldn't extract BaseSystem to path: /Volumes/Install macOS Beta/BaseSystem
The bless of the installer disk failed.

These are the steps I followed:

Code: 
hdiutil create -o /tmp/BigSur.cdr -size 10000m -layout SPUD -fs HFS+J
hdiutil attach /tmp/BigSur.cdr.dmg -noverify -mountpoint /Volumes/install_build
sudo '/Applications/Install macOS Beta.app/Contents/Resources/createinstallmedia' --volume /Volumes/install_build

At which point I get the error above.

I used
Code: 
  sudo hdiutil create -o InstallMedia -size 20G -layout SPUD -fs HFS+J -type SPARSE
  sudo hdiutil attach InstallMedia.sparseimage -noverify -mountpoint /Volumes/install_build
  sudo /Applications/Install\ macOS\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build
  sudo hdiutil detach /Volumes/Install\ macOS\ */
  sudo hdiutil convert InstallMedia.sparseimage -format UDZO -o InstallMedia.dmg
  sudo rm InstallMedia.sparseimage
 
I'm having trouble getting Parallels to run on Big Sur at all -- it simply throws up a message saying to reboot to complete the installation, hangs, and then after a manual reboot just throws up the error again. I looked in the log file and it seems to be failing to load kernel extensions with this error:

Error: Error Domain=KMErrorDomain Code=1 "Kernel request failed: (libkern/kext) kext (kmod) start/stop routine failed" UserInfo={NSLocalizedDescription=Kernel request failed: (libkern/kext) kext (kmod) start/stop routine failed}

At one point I had to approve the extensions in the Security System Preferences, but it did not help.
 
Since there are two separate issues being discussed here:
  1. Installing Big Sur on an existing Parallels installation as a VM.
  2. Installing Parallels on a Big Sur installation (either brand new or upgraded from previous version)
I was wondering if it was worth separating the threads to avoid confusion from readers. I personally am interested in getting Parallels to work on Big Sur, since I too get the constant restart message loop. So wonder how others were able to get it to boot VMs and notice the t/y/1/2 key errors.
 
I am also stuck with re reboot issue of parallels 15.1 on macos big sur beta 1.
It seams like someone got parallels to run on big sur: Is that version 15.1 or some 16 beta of parallels that will do the trick?
I'd love to have a solution for this so I am not required to roll back from big sur to macos x.
 
What worked for me was:

1. Download the Installer
2. Create a bootable image (Based on @Samus22 post)
3. Mount the image in Parallels 15
4. Configure the VM: Increase disk size to 128GB and set the boot flags (Based on @KyleE2 post)
5. Start Installing... choose a password that does not contain t,y,1,2
 
Also getting "BIErrorDomain error 3" when trying to upgrade to the Big Sur beta.
