Sierra install stuck a 5 minutes remaining

Right now I'm having the same problem with a MBP 13" mid 2012 trying to do a clean macOS Sierra install from a usb stick it stuck at 6 seconds remaining.

Same problem happen to me this january with a MacMini Late 2012 when doing the same clean install from a usb stick also it stuck at the same 6 seconds remaining.

That time I remember I tried to do the install many times and always got stuck at 6 seconds remaining. I really wanted to do a clean install but was not possible, what I did to solve the problem and get Sierra installed, was to do a clean install of El Capitan from usb and immediately after finishing, upgrading from the App Store to Sierra.

Update: After Mountain Lion was successfully installed, I restored data using Time Machine. As soon as I switched it on, it was back to Sierra and all I did was update to the llatest version. Et voila!

I would add, for the benefit of everyone, that what seems to be the download rate in the installer log (something like 0.87294%) isn't the real rate - actually in this case it's 87% completed, so almost finished (I was afraid it would take a month since I saw the blue progressing bar progress).

But I did several tries too. I was reinstalling Sierra so I knew it was compatible. First time it just failed, second time, after a night running, it was still stucked at 5 minutes remaining - and third time, I've read this post, discovered installer log window, it took about 8 hours of download but it finally worked.

Keep trying!

I had this problem trying to upgrade to Sierra on my MacBook Pro, which is about 5 years old. I decided in the end just to try holding the power button down to force it to turn off, then simply turn it on again. To my surprise it started up sweetly with the old OS, and the Sierra install icon had vanished. I won't be upgrading to Sierra after all, since this is now my secondary machine. Or I'll wait a few more months until Apple have sorted out the problems with Sierra; long experience has shown that this is how it generally happens and being an early adopter is a bad idea. I have Sierra on my new machine anyway and tbh can't see many differences.

Hello,

Did you solve this problem ? I'm having the same issue since 4 days. I did recovery mode but can't download high sierra as it gets stuck somewhere in download. I tried 4 times download starts but it is stucking last 50min or 1 hour. Can you help me please ?

thanks, same exact thing happened to me with my Macbook Pro (about 5 years old). Hung after 1st install reboot, was at max progress bar and I hit the power button to hard reboot and it came back with the new Sierra OS but all my old apps/files which surprised me as I was expecting a clean install. Depending on how things look I may redo the whole process and format the disk first (didn't do that this time). Good thing it is a non-primary work device that I don't need anything off.

Hi, this is what i did to my MacBook Air 2017

1. Hold Shift+Control+Option+P for 5 seconds
2. Turn on the MacBook then press and hold Option+Command+R+P as soon as you hear the chime. Press and hold until you hear the 3rd chime. (Make sure that you press and hold at the same time).

3. A folder with question mark sign will appear then you can now turn off the MacBook

The purpose of 1 to 3 is to reset to factory setting the MacBook (erase all data).

4. Turn on again the MacBook then press and hold Control+R (Internet Recovery will appear, make sure you have stable internet connection)
5. Go to Disk Utility and reformat the HD Drive (Select the erase)
6. Start the recovery process (This will take some time but make sure to monitor the installation process, you can click Window on the tool bar and select Installer Log)
7. Wait for the installation to complete.

Hope it'll help you guys as well.

That's about two days too long.

Force the Mac to shut down by holding its power button depressed for at least five seconds. It may fail to restart, but you really don't have any choice but to do that. If it does not restart, you will need to repeat the exercise. It's not possible to determine the reason it stalled at "about 5 minutes remaining".

Did you get a resolution? I have this issue too - erased my HDD after selling my machine and when I go to reinstall macOs it goes straight to 'about 5 minutes remaining' and just sits there....

The First Aid, format again, First Aid again, reboot, try the install seems to be working for me. We'll see how it goes, but my log (command+L to view) is at least moving now. Fingers crossed.

Shut down the computer using the power button and then restart.

You are welcome. See your post about this topic.

Have the same problem on my new 2700€ macbook pro and it's a big disappointment from Apple. Never experienced this ****** problems in the past. Make Apple great again. :(((((
