You’ll see messages like “Storage system check exit code is 0” and “File system check exit code is 0” here. You can click the “Show Details” drop-down message to view detailed information about any errors it encounters. If it finds any errors, it will attempt to automatically fix them for you. It depends which you select in the sidebar.Ĭlick “Run” and your Mac will check the disk you selected for errors. You can either run the First Aid function on an entire disk, or an individual partition on that disk.
