- Try First Aid in Recovery Mode
In some cases, Mac fails to find and repair disk or file system issues when you boot it into Safe Mode. This is due to the “live mode”. The check runs in live mode, examines the disk meanwhile the OS X is running from it. Thus, the check cannot make changes to the system drive.
