And while we have that specialized capability (and experience) far more often we can diagnose and correct errors on your MacBook and extract your precious and valuable data with resorting to extremes. IFIX New York is one of the few locations in New York City with a clean hood that allows us to safely open a Mac hard drive to conduct data recovery. Regardless of the Mac data recovery issue our technicians are skilled at file and permissions repair, computer forensics, database retrieval and bit-level data recovery. If your files are corrupted or missing iFIX New York can diagnose your hard drive and recover your data. If you don't have a separate backup of your data, contact Apple's support services for next steps.IFIX New York® can recover data from most MacBook hard drives If Disk Utility found errors that it was unable to repair, you may need to erase the disk and reinstall macOS. Repeat this step for each volume on the disk, then each container on the disk, then lastly the disk itself. After Disk Utility has completed the check, select the next volume or container above it in the sidebar, then run First Aid again.

If you can't click the button, skip this step for the volume you selected. Click Run or Repair Disk to check the volume for errors.

Start by selecting the last volume on the disk, then click the First Aid button. Beneath it you should see any containers and volumes on it.

The top disk in the side column is your internal disk.

Choose View -> Show All Devices from the toolbar in Disk Utility.

From the utilities window in macOS Recovery, select Disk Utility and click Continue.

If prompted, select a user, then click Next and enter the password.

Turn on your Mac and continue to press and hold the power button until you see the startup options window.

On Macs powered by Apple silicon, such as the M1 MacBook Pro, the process is a little different, as described in the following steps. On Intel-based Macs, pressing the Command-R key combination immediately on booting invokes Recovery mode. Fortunately, in such cases you can still get to Disk Utility from macOS Recovery. Disk Utility is Apple's go-to macOS app for finding and repairing common disk errors, but if it's your Mac's internal disk that's the problem, then your Mac might not even start up into macOS.
