Start up from macOS Recovery
- In this article, I’m going to show you the complete guide to fix VirtualBox errors while installing Mac OS X. Most of the website that creating content regarding the installation of Mac OS X El Capitan or macOS Sierra on VirtualBox is not complete and have errors.
- Now Select Install a new copy of MAC OS. It will take 45 minutes to install here. After completing this process your MAC will restart and do the installation again for 45 minutes. ( I dont know why it happened two times but both the times it was real quick. It didn't freeze anywhere.) I think the Internet recovery thing does something to fix.
Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
Download Mac Os High Sierra; Mac Os High Sierra Iso Download; Download Mac Os Sierra Free; The above method didn’t work in my case. Still stuck at 17.7 Mb. I was going to give up then this crazy thing came to my mind. 1) I booted from a El Captain working OS and connected the Sierra beta HD as an external drive. Hopegrad said: Hi Everyone: My install problem is a little different from others. I am stuck on the OS X install screen. The status bar is not moving at all with an estimated install time of 33 minutes. However, it has been this way for 45 minutes.
Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.

Follow these guidelines during installation:
Mac Os Sierra Installation Stuck On Windows
- If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
- If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
- If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
- Allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.
After installation is complete, your Mac might restart to a setup assistant. If you're selling, trading in, or giving away your Mac, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.
Other macOS installation options
When you install macOS from Recovery, you get the current version of the most recently installed macOS, with some exceptions:
- On an Intel-based Mac: If you use Shift-Option-Command-R during startup, you're offered the macOS that came with your Mac, or the closest version still available. If you use Option-Command-R during startup, in most cases you're offered the latest macOS that is compatible with your Mac. Otherwise you're offered the macOS that came with your Mac, or the closest version still available.
- If the Mac logic board was just replaced, you may be offered only the latest macOS that is compatible with your Mac. If you just erased your entire startup disk, you may be offered only the macOS that came with your Mac, or the closest version still available.
You can also use these methods to install macOS, if the macOS is compatible with your Mac:
Mac Os Sierra Upgrade
- Use the App Store to download and install the latest macOS.
- Use the App Store or a web browser to download and install an earlier macOS.
- Use a USB flash drive or other secondary volume to create a bootable installer.
