Hi All,
I can not create the USB bootable pendrive for upgrade to macOS High Sierra 10.13.3 on Mac mini (Late 2009) - 2.26 GHz Intel Core 2 Duo processor - 4GB DDR3 1067 MHz memory - NVIDIA GeForce 9400 graphics 256MB - OS X 10.11.6 El Capitan (Build 15G19009) - System Integrity Protection: Disabled.
For the creation I use macOS High Sierra Patcher Tool version 2.5.4 and install macOS High Sierra.app 10.13.3 version 13.3.02 (I have downloaded through the tool).
As a USB device I use a 16GB pendrive formatted in HFS+ (journaled) with GUID partition map, volume name "install".
The creation procedure is done from the internal disk with OS X El Capitan, but I'm going to upgrade macOS Sierra 10.12.6 (with all the security updates installed) that I have on an external USB drive.
Trying to boot with the Alt/Option key presses displays a USB drive with the name "install" but, selecting it, the Apple logo appears for a few seconds, immediately afterwards, the prohibition signal and the Mac starts with the internal hard disk.
What can I do?
Finally, the following messages are logged in the Console after booting from the internal disk, which may be related to the problem:
Code:
25/03/18 13:40:27,000 kernel[0]: hfs: mounted install on device disk1s2
25/03/18 13:44:26,459 com.apple.kextd[45]: Note: /Volumes/install/System/Library/Kernels/kernel: No such file or directory

25/03/18 13:46:18,040 deleted[303]: _validateVolume:813 unable to normalize volume: "/Volumes/install", vol: (null)
Thank you all!
Note:
I tried to perform the procedure of creating also from my installation of macOS Sierra (patched) but the result is the same: the Mac mini does not boot from the USB stick!
