#OPEN DISK UTILITY IN MAC SOFTWARE#

You cannot Repair the disk that is running your Mac system. If Repair Disk Permissions has failed to improve system performance, use the Repair Disk option that's located to the right of Repair Disk Permissions. (The Verify command may identify a problem but you'll still need to fix it, so use the Repair command so you don't need to run the problem-finding function twice.) Disk Utility will do its best to identify and repair any permissions problems that may be affecting performance. In the First Aid pane beside it look to the bottom left and you'll find two commands, 'Verify Disk Permissions' and 'Repair Disk Permissions'. Launch Disk Utility and select your Mac in the list at the left of the app window. Why would these be different? For example, some third-party apps make temporary changes to System permissions as part of the installation process but some fail to restore permissions once installed. It checks what those permissions should be against those you have on your computer. This verifies and repairs permissions on the system and Apple apps on your Mac. Once you've backed up your data and restarted your Mac, the first thing you could try using Repair Disk Permissions. You can sometimes repair these problems using Disk Utility, which offers two key tools, Repair Disk Permissions, and Repair Disk. When this happens your Mac can have a tough time finding or using that data, which slows down the overall performance of your machine. Sometimes information can be damaged in some way. This helps your operating system find the data and make sense of that information, retrieving it from storage on the disk or volume. Your Mac stores all your data in a directory on your disk. All your data is software, too, so even this can be affected.

Macs are computers and like any computer the software on your disk can degrade. You are experiencing degraded system performance after a power cut.
