If you used Disk Utility from macOS Recovery, you can now restart your Mac: choose Apple menu  > Restart. The order of repair in this example was Macintosh HD - Data, then Macintosh HD, then Container disk4, then APPLE SSD. Keep moving up the list, running First Aid for each volume on the disk, then each container on the disk, then finally the disk itself. If you're asked for a password to unlock the disk, enter your administrator password.Īfter Disk Utility is done checking the volume, select the next item above it in the sidebar, then run First Aid again.If the button is dimmed and you can't click it, skip this step for the disk, container, or volume you selected.How do I choose which format my CD imports using: Open iTunes on your Mac or PC. But it’s a good idea to make sure your songs are the right format for when it does work. The format you choose shouldn’t affect whether iTunes can upload your CD to iTunes or not. If there is no Run button, click the Repair Disk button instead. Most people can’t notice any difference, certainly on tiny earbuds.If no programs will open the CD file, you can ask software developers for help.

Look for the file type listed under Kind.

In this example, the last volume on the disk is Macintosh HD - Data.Ĭlick Run to begin checking the selected volume for errors. Select More Info from the drop-down menu. For each disk that you're repairing, start by selecting the last volume on that disk, then click the First Aid button or tab.
