Sierra installation stuck. This is so Un-Apple :(

How did you manage out of the loading bar screen after the restart when it wouldn't finish loading?

did you notice that this thread is almost a year old....

Before someone replies "you were supposed to...", NO. I wasn't supposed to do anything, Apple software should just work, including upgrades.

I have to agree somewhat. Apple should work harder to make upgrades "idiot-proof".

i don't think it's possible to completely idiot-proof software. Or hardware. Ideally the OS X installers would never run into problems, but in the real world, the OS installers will be run on systems that have been poorly maintained by the people who own/use them, and who don't take even the most elementary precautions before upgrading. If Apple spelled out the safest ways to upgrade, I suspect that a majority of users would not read and follow those instructions. Lots of people don't have any idea what to do, and also don't want to learn: I have a friend like that. Overcoming that is just not possible.

I find that Apple is doing more "idiot-proofing" than is really desirable these days.

So you're saying having the installer check whether there's enough space left to install the new OS (which is about five lines of code) is mollycoddling the user, and if they don't check it themselves it's OK to have the install crash completely if it runs out of space?

I don't think that's what he said. Plus the installer does check if there is enough space and will say so when there isn't and stop. Not sure where you got the idea it would continue to try and install then crash.

If you use Time Machine to back up your Mac, you can easily revert to a previous version of OS X if you experience trouble after installing an update.

1. Print these instructions.Click the Share button in the Help window, then choose Print.
2. Choose Apple menu > Restart. After your Mac restarts and you hear the startup chime, hold down the Command (⌘) and R keys.When the Apple logo appears, you can release the keys.
3. Select “Restore from a Time Machine Backup,” then click Continue.
4. Select your Time Machine backup disk.
5. Select the Time Machine backup you want to restore. To restore your computer to the state it was in before you installed the new version of OS X, choose the most recent backup that occurred prior to installing OS X Yosemite.
6. Follow the onscreen instructions.

If you backed up files as described in the Important message above, you can restore them now. If you backed them up using Time Machine, click the Time Machine icon in the menu bar, choose Enter Time Machine, then retrieve your files.

Same for me - from El Capitan to Sierra - 3 times have had to revert to Time Machine - reinstallation works however is a pain to be polite - all works until the restart when is stops - black screen with loading timeline icon at ¾ complete - nothing continues.

On restart it is the same even after the steps of NVRAM, SMC and Safe Mode etc

Online help - not helpful - I don't understand some of the instructions about k files.

Same for me, even I reinstall to 10.11 and try upgrade again to Sierra. It still fail. Don't know what happen, I have never experience this with Apple products before. I am so disappointed.

We are not Apple here. Just users like you. Make a feeback post to Apple.

Contact Apple support for assistance!

Idiots can be very inventive.

Indeed.
