Been trying to install 11.5 on my MacBook Air and it keeps getting stuck at "about 53 minutes remaining." I've downladed from the app store, not just the update (which has been a problem for me in the past). I've tried maybe a dozen times with same results. And yes, I've tried Safe Mode, but same there too. Anyone else having/had that problem? Any sugggestions?
MacBook, macOS 10.15
Is FileVault enabled and if so has it finished Decrypting the drive Before attempting the update to 11.5. If Yes, try Disabling FileVault and allow it to finish. Then - suggestion below
This method may seem unnecessary but sometimes the Router Restart clears Network issues from ISP to Apple Servers
Shutdown Router. Shutdown computer and disconnect all External Drives. Restart Router. Connect to Router via Ethernet Cable. If via Wifi - Disconnect all other Devices using the Wifi - want the Maximum Bandwidth only for this computer. Restart computer in Safe Mode. It does a Repair Disk, Clear System Cache files and only load Apple Software, extensions and Fonts. Will load slowly - Normal. Once Logged in - open Apple Apps Store and Get the Full Version of Big Sur. It will take some time and several pauses will occur - normal. Countdown clock may say 15 minutes but in Real time may be 30 minutes. Same goes for clock at 10 minutes could be 20 minutes in Real time. Eventually , Full Installer will download and a New Application in Applications Folder will present called Install Big Sur. Stop there and perform a Time Machine Backup. If desired - have an External Drive - Copy & Paste the Install Big Sur Application to external drive for future usage - making a Bootable Installer. Now run the Installer.
Have found this method more reliable than the Software Update which is very iffy at best
Thanks, Bailier, but I did read that article and I don't think it applies to my situation. To be clear, this is the screen on which the installation is stuck. It never goes beyond this point and I have tried at least a dozen times:
Thanks for the reply, Chuck. But I don't think that fits my problem. I have no problem starting up. The issue is with my attempts to install the Big Sur 11.5 update. The installation gets stuck, every time, with "about 53 minutes remaining." I've tried doing it in safe mode and it doesn't make any difference.
baconwrapped,
The article provided would be the best steps to follow. Starting the installation from safe mode, wouldn't impact any issue during installation as the Mac restarts which brings up the Apple logo and progress bar, thus taking it out of safe mode. Go ahead and follow the steps under "If your Mac is stuck on this screen". If the issue continues, contact Apple Support.
Cheers!
Is there an Active and Working Internet Connection at this point. Reason- the Installer might be looking for some Boot ROM and iBridge ( Touch ID Equipped machines ) updates along with the update being installed.
Thanks, P. Phillips. Yes, the internet connection is working and strong. Definitely not the issue. This kind of thing has happened with various past updates as well, including the last one, 11.4. But with those, when I tried again in safe mode it worked fine. This time not even that is helping. And of course I've tried rebooting as well. No problem with the computer otherwise. Just can't get Big Sur 11.5 installation to progress further than shown in the photo.
Must inquire - any Antivirus, Cleaners, Optimizers installed and have been run on this unit ? If Yes, strongly suggest Removing as Per Developers Specific Instructions
Any of the above, even is deactivated, are going to interfere with the whole process. and zero return for what they purport to do which is nothing more that cause havoc and even corrupt the OS
Any luck with the installation? I've been having the same stuck on a MacBook 12" 2017 and nothing I do, even the fastest connection I can find will fix it. Once, it did go all the way to the end and the laptop restarted a few times as you would expect but then after booting, back to the same update prompt.
Thank you in advance
Hello baconwrapped,
For the issue you've described we recommend that you follow the steps here: If your Mac starts up to an Apple logo or progress bar
Cheers!
Thanks again, but File Vault is disabled, and I have tried from Safe Mode and have used the Apps Store download through the whole process. Still no luck.
Sadly no... I tried again when 11.5.1 was first offered, but same results. It downloaded fine, but installation still got stuck with 53 minutes remaining. Same same same....
Sorry to hear that. For now, we haven't noticed any Perfomance issues so we'll just keep closing the prompt. Hope Apple release a fix soon.
Thank you for taking the time to respond.
Of course. Thank you for sharing your experience as well. Also hope they can/will fix it.
Big Sur 11.5 update installation stuck
