Sierra install stuck a 5 minutes remaining

Can't upload my screen's picture but there's only maybe half an inch of the progress bar to load for over 10 hours. It doesn't show how many minutes. Tried restarting and it goes back to the same screen. Command+L doesn't do anything.

Hi Smwilsey,

Unfortunately it is not solved yet. There are many threads about this kind issue with Sierra, it looks like Sierra has serious problems on upgrading on olds macs.

By using Command+V (verbose mode) I can see the mac doing this:

- AppleKeyStore: operation failed ........

- AppleMCP89TMS: powerGettingDown (0): Done

- SmartBattery: finished polling type 1

- busy timeout [0]......

- SmartBattery: finished polling type 1

- busy timeout [1]......

- IOConsoleUsers: time(0) 0->0, lin 0, link 1

- IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, nov 0, sm 0x0

- SmartBattery: finished polling type 1

- SmartBattery: finished polling type 4

- SmartBattery: finished polling type 4

- SmartBattery: finished polling type 4

- SmartBattery: finished polling type 4

- SmartBattery: finished polling type 4

- SmartBattery: finished polling type 4

- SmartBattery: finished polling type 2

- Smart....

(It is just looping at the SmartBattery, not going forward)

Here some tips and tricks very useful:

However, I was able to do the backup of all data stored on the hard disk.

-> I switched off the mac (keeping pressed the power button for 6 seconds), then I restarted it again by pressing the Option key (alt), and it went on the Recover mode. Form Terminal I copied all the most important directories onto an external hard drive.

From the Recovery mode you can do many things:

- browsing on Safari

- Reinstall OSX

- Utility Disk

- Terminal

Now, I am going to:

- switch off the mac pressing the power button for 6 seconds

- restart the mac by pressing Option key (alt)

- from the Recovery mode I will use Utility disk to fully scratch the hard disk (format)

- then, staying within the Recovery mode, I will launch again Reinstall OSX

Crossing fingers!

Touching wood!

I missing you Steve!!!

Hey just keep trying it over. again and again evey 5 min if you dont see it go down to 4. Im not 100 percent on this but i think scroling down on the agreement helps aswell. I took these pics as i was typing lol

Thank you! After days and days trying I managed to install it after formatting the computer, but needed some files and used time machine to go back to the old system.

The computer had been crazy slow for a while and seemed to only get worse after all this, so I sent it to a professional and turns out I have a problem on my HD and need a new one.

Do you think it´s worth it to spend on a SSD for my Mid-2010 machine instead of buying a new Macbook (4 times more expensive than the SSD where I live)?

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!

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.

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. :(((((

I ann in the same situation. It's been almost 24hours since I began installation and I'm stuck at this screen in the picture for at least 10 hours. Did you have any luck?
