I am trying to upgrade to macos Sierra on my 2014 macbook Air. I downloaded the upgrade and whenever i tried to update it my installer gets stuck at 'Installing: About 29 minutes remaining'. Its stuck in this stage for over 6 hours and I dont know what is wrong. Any suggestions would be appreciated. Anyone else having the problem? Many thanks!
MacBook Air, OS X El Capitan (10.11.6), 2014 macbook Air
I'm having this problem too. 2012 iMac. I have just replaced a cracked screen and took the opportunity to install an SSD (SATA).
I internet-booted to Recovery mode, formatted the drive, and re-installed the OS. Apparently Internet Recovery will only install the OS that came on the computer. (In this case, Mountain Lion.) That went fine. I set up the computer, downloaded the Sierra installer from the App Store, and ran it. I ended up with the OP's symptoms exactly. Stuck at "29 minutes remaining."
I had previously tried a Time Machine restore of the drive that was previously in it. The Mac seemed to boot, but at the end of the sequence, just when the Desktop should load, I get the "No" symbol (circle with a slash).
Six house is way too long ..
Check the startup disk.
Open the Disk Utility app located in /Applications/Utilities
Then select the startup disk on the left then select the First Aid tab then click Run.
Do this:
Repair the Drive for El Capitan
Now, re-run the Sierra installer.
Thank you very much for the replies Carolyn and Kappy. I did like what you have suggested but still the installer gets stuck at that time frame showing "Installation in progress: About 29minutes remaining". While installing, after showing this message, the computer was shut down automatically, which i found to be bit weird. After manual restart it went back to the same state of showing 29 min remaining. Confused!
I have exact same issue on a MBP 15: 2014 retina currently running latest El Capitain...installation hangs at 28%..have tried redownloading installer, creating boot USB and install from that..copy installer to external SSD drive and install from that....rebooting into safe mode hangs computer....CMD OPT P R has no effect..disk utilities from recover does not see internal drive...ugh....any ideas other than wiping drive and install new???
I have exactly the same problem on mac book pro 2011. The mac sierra installer reached 33% and will not go any further.
Terrible job, must not of been tested on the older models very slack of apples deployment team indeed. I hope sierra works well and is not going to slow me down any more. The best version in terms of speed was still 10.7.5 its all been downhill since then sadly.
Have you figured anything out? Now my computer won't even restart
