I had the same problem with the EFI mount error.
Just renamed my EFI Partition from EFI mSATA to EFI and the installation run ok

to resolve this issue
mount EFI partition with clover or Efi mounter, then open MultiBeast again and you're ready to install any kexts you want

9/10 times this means I have neglected to make sure EFI is unmounted as Multibeast does it for you. 1/10 I have 2 EFI volumes mounted.

2. No such file or directory
3. Command not found

Thanks, this worked for me. Here's a consolidated summary:

Code to enter, with formatting adjusted:
Code:
sudo launchctl unload /Library/LaunchDaemons/com.tonymacx86.InstallHelper.plist
sudo rm /Library/LaunchDaemons/com.tonymacx86.InstallHelper.plist
sudo rm /Library/PrivilegedHelperTools/com.tonymacx86.InstallHelper

If you get an error, check in Finder to confirm the following folders exist on your hard drive:
/Library/LaunchDaemons
/Library/PrivilegedHelperTools

The files being deleted should be in there.

While in Finder, check if you have more than one EFI partition mounted (under Devices group in left margin). If so, unmount the one on the USB stick (the one on the hard drive will have a small circle inside the icon). Only unmount the EFI partition, not the whole stick.

The WHY
I don't know well enough to say definitively, so please correct me if I'm wrong. It seems this may be happening if MultiBeast is not able to overwrite the necessary files so the SUDO command is for you to manually unload and delete them. Unmounting extra EFI partitions may be to address MultiBeast from being unable to determine which EFI partition you want to build to.

sudo launchctl unload /Library/LaunchDaemons/com.tonymacx86.InstallHelper.plist

This command gives me:

/Library/LaunchDaemons/com.tonymacx86.InstallHelper.plist: Could not find specified service

sudo rm /Library/LaunchDaemons/com.tonymacx86.InstallHelper.plist sudo rm /Library/PrivilegedHelperTools/com.tonymacx86.InstallHelper
This deletes files. But then I even re-download and run MultiBeast 11.0.1 - Mojave - got the same error in its log:

03/27/19 21:34:07 - Starting MultiBeast 11.0.1-1
03/27/19 21:34:35 - Failed to bless helper. Error: Error Domain=CFErrorDomainLaunchd Code=9 "(null)"


Please help me..
