I'm trying to update my 2011 MacBook pro from OS X 10.7.5 to the latest version Sierra.
Pre-Mojave, you may be able to fix a stuck update by going to the Mac App Store, finding the software you are downloading, and pressing Option/Alt. When you do so you should see the option to. Try restarting your Mac while holding down the Option key to bring up startup manager. Then choose the disk you want to start up from. Alternatively, start up holding down the Shift Key to use Safe Mode. It runs through a series of checks to see if everything is in working order. See this article for more details and next steps. Mar 11, 2013 Delay Startup. Delay Start is a free Mac app available in the Mac App Store that allows you to choose a delay time for startup apps to launch. Just the app, add all the apps you want to delay the launch of in the ‘Apps to be started:’ list using the + button, enter a.
Basically the install won't finish and gets stuck on a page with an apple logo and loading bar (see photo). I've tried all of the recovery mode stuff and restarting the Sierra install. For some reason I can't just go back and reinstall 10.7.5 because Sierra is now installed on to my Hard Drive?
I also had about 30gb of free disk space.
This is really annoying me as I am a music producer and heavily rely on my laptop.
I'm also worried about my data being lost?
Can anyone please help?

Available only on Mac computers that have the Apple T2 Security Chip, Startup Security Utility offers three features to help secure your Mac against unauthorized access: Firmware password protection, Secure Boot, and External Boot.
To open Startup Security Utility:
- Turn on your Mac, then press and hold Command (⌘)-R immediately after you see the Apple logo. Your Mac starts up from macOS Recovery.
- When you see the macOS Utilities window, choose Utilities > Startup Security Utility from the menu bar.
- When you're asked to authenticate, click Enter macOS Password, then choose an administrator account and enter its password.
Firmware password protection
Use a firmware password to prevent anyone who doesn't have the password from starting up from a disk other than your designated startup disk. To set a firmware password, click Turn On Firmware Password, then follow the onscreen instructions. Learn more about firmware passwords.
You can also use External Boot to prevent even those who know the firmware password from starting up from external media.

Secure Boot
Use this feature to make sure that your Mac starts up only from a legitimate, trusted operating system. Learn more about Secure Boot.
External Boot
Use this feature to control whether your Mac can start up from an external hard drive, thumb drive, or other external media. The default and most secure setting is ”Disallow booting from external media.” When this setting is selected, your Mac can't be made to start up from any external media:

- Startup Disk preferences displays a message that your security settings do not allow this Mac to use an external startup disk.
- Startup Manager allows you to select an external startup disk, but doing so causes your Mac to restart to a message that your security settings do not allow this Mac to use an external startup disk. You'll then have the option to restart from your current startup disk or select another startup disk.
To allow your Mac to use an external startup disk:

- Open Startup Security Utility.
- Select ”Allow booting from external media.”
Your Mac doesn't support booting from network volumes, whether or not you allow booting from external media. - If you want to select an external startup disk before restarting your Mac, quit Startup Security Utility, then choose Apple menu > Startup Disk.
