Hi, @Mennaruuk, did you use the correct format and scheme?
Name: [vary]
Format: Mac OS Extended (Journaled)
Scheme: GUID Partition Map
createinstallmedia
again:sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/[volumename]
sudo ./micropatcher.sh
and sudo ./install-setvars.sh
:sudo bash ./micropatcher.sh /Volumes/[volumename] ; sudo bash ./install-setvars.sh /Volumes/[volumename]
If the above method doesn't do so, you can copy it manually. Just follow the steps below.
(However, you need to do sudo ./micropatcher.sh
first.)
diskutil list
. This shows current volumes attached to your Mac.
For example, I'll use /dev/disk2
.
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *251.0 GB disk0
1: EFI EFI 314.6 MB disk0s1
2: Apple_APFS Container disk1 250.7 GB disk0s2
/dev/disk1 (synthesized):
0: APFS Container Scheme - +250.7 GB disk1 Physical Store disk0s2 1: APFS Volume Macintosh HD 14.9 GB disk1s1 2: APFS Snapshot com.apple.os.update-... 14.9 GB disk1s1s1 3: APFS Volume Macintosh HD - Data 95.3 GB disk1s2 4: APFS Volume Preboot 327.0 MB disk1s3 5: APFS Volume Recovery 655.4 MB disk1s4 6: APFS Volume VM 3.2 GB disk1s5
/dev/disk2 (external, physical):
0: GUID_partition_scheme *61.5 GB disk2 1: EFI EFI 209.7 MB disk2s1 2: Apple_HFS Install macOS Big Sur 61.2 GB disk2s2
2. Run `sudo diskutil mount [diskname]s1`, for example `sudo diskutil mount /dev/disk2s1`.
3. Run `sysctl -n hw.model`.
* If you see `iMac14,1`, `iMac14,2`, or `iMac14,3`, you can run this command: `sudo cp -r ./setvars/EFI-enablesiparv /Volumes/EFI/EFI`
* Otherwise you can run this command: `sudo cp -r ./setvars/EFI /Volumes/EFI/EFI`
4. Now, unmount the EFI partition:
sudo umount /Volumes/EFI || sudo diskutil unmount /Volumes/EFI
I hope this helps. If the second method doesn't do so neither, please let me know.
The second method worked perfectly! Now I successfully made a bootable Big Sur installer disk. Thank you!
I keep encountering this problem.
createinstallmedia
goes smooth. So doesmicropatcher.sh
. However,install-setvars
(run with sudo) does not work. I used Disk Utility to successfully format the USB stick as HFS+ on GUID partition map. The error persisted. I followed the advice in this Reddit post suggesting tosudo mount -u -w
the USB flash before runninginstall-setvars
. Unfortunately that didn't get me anywhere but to the same error.
