After downloading 10.13.4 update and pressning restart buton the screen goes black with a visible currsor arrow and then nothing. It actually never turns off (never turens off touchbat and keyboard lights). After a few hours I interupt by pressning the start (touchID) key. starting of the computer brings it back to 10.13.3.
I have done hardeware test and resetrend PRam without any problems deteced. also downloaded the combo installer with the same results. Now after this I can no longer restart the computer. It asllways hangs at this pre turn off state.

2017 15´ macbook pro w TB.

greatfull for suggestions on how to proceede
 
Boot to Recovery and run First Aid on your Macintosh SSD. If everything checks out OK, reinstall High Sierra from Recovery. You won't lose data or apps by reinstalling. Do you have a backup?
 
Sounds like a good idea. I will do this when i hav finished two importan projects. However, am I the only one having this problem? Have everyone done reinstallation's? I have had macs for nearly 20 years. This is the first softare update that have caused problem since OS10.2
 
Some Macs get a firmware update, which may be the cause of your problem. If you can use target disk mode with another Mac that has not been upgraded, then you may be able to complete the upgrade. That worked for me with a 2011 Mac mini that was hung and which I then put into target disk mode, and a Mac mini 2012 that I started up with the option key to select the 2011 Mac boot disk.
 
Reinstall from recovery is a good first start. If you're computer was already on 10.13.3 then firmware shouldn't be the issue as it has already been applied. Best thing you can always do is put yourself in a position to always be able to do a clean install. Have all important files backed up in some way and the ability to install all apps cleanly. It may be annoying but guarantees problem solved unless it's hardware.

Further, do command option R at boot will cause reinstall to be to 10.13.4.
 
Thanks booting from the recovery partition did the trick, Took nearly an hour but now I am on 13.4.

However the inability to reboot persist. screen goes black with a movable cursor arrow and touch bar and keyboard are still shining. This is not super bad but somewhat annoying.
 
Do you know if this issue is with your machine specifically, or if it's a general known issue with your machine. I'm on 10.13.5 (a beta) and when I was on 10.13.4 it would restart just fine.
 
i have a 2017 macbook pro 15 wtb
I hope it is not a hardware problem but it might be. I reseted PVram again and now it is stuck at restart
(progress bar is at approx 95%). it start in safe mode though. and after a few restarts in normal mode as well.

I guess i have to go to some kind of apple store
 
Update.
The problem persist using and other user. It persist in safe mode. It persist a system restore using the recovery partition. It is also not affected by resetting pVRAM. But if I run Onyx and do the standard maintenance tasks the computer reboots normally.

After the hanging at robots the machine turns of if you press the power button for five seconds and if you then reboot it works normal except that some settings are changed like desktop picture is changed to something i used ages ago.

This happened to me on my 2017 iMac.
Do you have an external HD attached? I have to drag mine to the trash for mine to get past that spot you describe. After ejecting the external it restarts or shuts down just fine.

Tried the minted disc solution without success
Only clean install left to do before handing in the computer for replacement
I am glad I have AppleCare
 
clean install fixed the thing. I had a very old system folder with leftover since 10.7 so I guess it was about time to do it ;)
 
Glad you got it sorted. I did a clean install initially just because of the new file system. Have not had any problems.
