Stuck at 100% loading bar

I had the same issue so I booted from my external backup clone, which was Sierra went to disk utilities and did first aid on my internal drive with HS then all was OK.

Hi Kitty,

macOS High Sierra upgrade has created a lot of issues, but it can be resolved with the update, however for some reasons downloading it from Apple Store Updates has been a disaster for many of us... either couldn't install and when we eventually managed to install it, it created a lot of issues, such a slow system, crash finder, system freeze, spotlight issues... Luckily there is a way around it! Anyway try this:

• Reboot with the option key and get out of the macOS install drive and restart with your normal Mac drive
• Check on App Store update if the 10.13.2 update has been installed
• If not and the update is not present on the available update download then download the combo update 10.13.2
• 10.13.2 Combo Update
• Make sure you have a full backup, ideally time machine, as if there is anything going wrong it is the safest way to reinstall it from the recovery!
• Update

Let me know if it helped and more importantly, in a later stage if it did the trick, as it seems that there are a high volume of issue with the 10.13.2 update, and it would be important to inform other users of a way to resolve it!

Good luck 😎
