Can't update macos to 10.13.1

[rramalho]

Hi all,
I have a Mac Mini (late 2012), 2.3GHz i7 with 16Gb of RAM. It has one SSD and a HDD, both 1TB.

It's a triple boot setup. I need macOS, Windows and Linux to boot. They all do, and I use refind as a bootloader. This kind of setup has worked for me for as long as decade now

But I can't seem to install macOS 10.13.1 update on this machine. I've tried the App Store approach, the combo updater approach, none of them work.

After the reboot it always fails with the message:



Disk Utility output is the following:
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *960.2 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_HFS MacHD 429.7 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
4: Microsoft Basic Data BOOTCAMP 429.4 GB disk0s4
5: Microsoft Basic Data 100.0 GB disk0s5

/dev/disk1 (internal, physical):

2: Microsoft Basic Data DATA 967.9 GB disk1s2
3: Linux Swap 31.9 GB disk1s4

The protective MBR of the first disk is the following - via the gdisk program:
Disk size is 1875385008 sectors (894.3 GiB)
MBR disk identifier: 0xB0940040
MBR partitions:

2 409640 839616903 primary 0xAF
3 839616904 840886439 primary 0xAF
4 * 840886440 1679474767 primary 0x07

The relevant content from /var/log/install.log is in an attachment.

I'm really stuck.

Thanks for any help.

I'm going to guess that the "refit" is in conflict with something in High Sierra.

Perhaps the "best way forward" on a multiple-boot setup like this would be to get an external USB3 SSD, install High Sierra onto it (and nothing else), and use the SSD as your High Sierra booter.

Only "a guess" on my part...

I've solved this.

I booted macOS in safe mode. Started the installer and voilá, it worked.

My mac is now in 10.13.2.

Thanks,
