Progress bar keeps restarting during macOS installation

I am trying to reinstall macOS, I deleted and used first aid on my MacIntosh volume before starting the process. It’s currently showing an apple logo with a progress bar starting at 29 minutes left. At 16 minutes it restarts and goes back to 29 minutes.

Ive tried to:

  • Shut down the mac and retry the download.
  • Used CMD + R and done a first aid check on the volume.
  • Deleted the volumes once again and retried the macOS installation.

After I tried to download macOS it showed me an error with the text written as an “startup/error”. After this occurrence I decided to use CMD + R again and retry the installation. I am currently stuck again on the progress bar that never seems to load. How do I fix this? I cant even use the laptop since it shows me the bar with the apple logo every-time I open it.


I have an Macbook Pro 2015

MacBook Pro 13″, macOS 12.7

Try booting into Internet Recovery Mode using Command + Option + R to bypass the local recovery mode on the internal SSD.


If you are performing a clean install of macOS on an Intel Mac, then it is best to erase the whole physical drive in order to create a new partition table as well as file system. Unfortunately Disk Utility hides the physical drives by default so you may need to click "View" within Disk Utility and select "Show All Devices" before the physical drive appears on the left pane of Disk Utility.


It would be best if you can create & use a bootable macOS USB installer since it eliminates all the problems associated with Internet Recovery Mode & networking issues. However, if you erased this laptop, then it would require access to another working Mac from 2007 to mid-2022 assuming your laptop is actually a 2015 model and not just purchased in 2015.


Generally to create a bootable installer for:

  • macOS 12.x -- requires a model 2015 to mid-2022
  • macOS 11.x -- requires a model Late-2013 to mid-2021
  • macOS 10.15 -- requires a model 2012 to mid-2020
  • macOS 10.13 -- requires a model Late-2009 to mid-2018
  • macOS 10.11 -- requires a model 2007 to 2015 (if the laptop has a third party internal SSD, then this is not an option unless you are installing to an external drive)


Those are just general models, but you can confirm the other Mac is compatible with the OS you want to create by using the information in the following article:
