If the drive is 'Verified' then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. Aug 14, 2019 External hard drive connected to a USB, FireWire, or Thunderbolt port on your Mac; Time Capsule or macOS Server on your network; External hard drive connected to the USB port of an AirPort Extreme Base Station (802.11ac) on your network If your backup drive isn't connected using one of these methods, Time Machine might not work.
Time Machine system requirements
Before using Time Machine, you need an external storage solution, sold separately:
- External hard drive connected to a USB, FireWire, or Thunderbolt port on your Mac
- Time Capsule or macOS Server on your network
- External hard drive connected to the USB port of an AirPort Extreme Base Station (802.11ac) on your network
If your backup drive isn't connected using one of these methods, Time Machine might not work. Check with the device manufacturer for compatibility and connection information.
If your setup meets these requirements, but you still can't use Time Machine, check these things:
Check your Mac
- Make sure that your Mac software is up to date.
- Restart your Mac and see if the issue continues.
Check your AirPort base station
- If you're using an AirPort Time Capsule or a drive connected to an AirPort Extreme Base Station, make sure that your AirPort firmware is up to date.
- Restart your base station and see if the issue continues. To restart, unplug the base station from AC power for 5 seconds, then plug it back in.
Check your network connection
If you back up to a server, AirPort Time Capsule, or drive connected to your AirPort Extreme Base Station, make sure that your Mac is connected to the same network as your backup drive. You can select your wireless network from the Wi-Fi status menu.
Check your backup
If you back up to a server, AirPort Time Capsule, or drive connected to your AirPort Extreme Base Station, make sure that your current Time Machine backup doesn't have any issues that could prevent further backups:
- While holding down the Option key on your keyboard, click the Time Machine menu in the menu bar, then choose Verify Backups.
- If Time Machine finds an issue with your backup, it displays a message with details. Follow the onscreen instructions.
Check your drives
- If you're using a drive connected to a port on your Mac or AirPort Extreme Base Station, make sure that the drive is turned on.
- If you're using a USB hub or a similar device, try connecting the drive directly to your Mac or base station.
- If you're backing up to an external third-party drive, check with the drive manufacturer to make sure the drive's firmware is up to date.
- If you're backing up to an external drive, check the formatting of the drive. Time Machine requires that an external drive be formatted like a Mac startup disk: Mac OS Extended (Journaled) with a GUID Partition Table (GPT). If you select a differently formatted drive for use with Time Machine, your Mac automatically prompts you to erase it for Time Machine.
Reformatting a disk erases all data stored on the disk, so you might want to move important files to another disk first.
If your drive is already formatted correctly, turn off Time Machine, then check it for problems:
- To check the drive of an AirPort Time Capsule, follow the steps to verify an AirPort Time Capsule drive.
- To check an external drive connected to your Mac, open Disk Utility from the Utilities folder of your Applications folder. Then use the First Aid feature in Disk Utility to verify your disk. Do this for your startup disk as well.
You can turn Time Machine back on after your drives are verified or repaired successfully.

If you don't get a startup chime then you may have a worse problem. Just be prepared.
What year is your MBP? From 2011 onward you would use Internet Recovery. Earlier you would need to install the original software that came with the computer on software restore DVDs.
Internet Recovery
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.

3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet
if possiblebecause it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.
DVD Installation:
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
with your computer. Insert the disc into the optical drive and restart the computer.
