![]() ![]() ![]() Need to copy a hard drive? Check out our guide to creating a bootable backup Apple removed those features in El Capitan. Disk Utility was a great way to copy a disk or convert it to an ISO. While most new Macs don’t have an optical drive, some of us still need to burn CDs and DVDs. Serious errors still need advanced utilities like Disk Warrior to fix the system. That saves a few steps from previous versions. Now you select the volume and click First Aid. Instead of Verify Disk and Repair Disk, the options merged. The options for repairing a disk changed. The Disk Utility in recovery mode does support creating a RAID. Also, improper use of the RAID function could cause problems with the Fusion drive scheme.Īnother option is to reboot your Mac into Recovery Mode. Creating a RAID is specialized functionality so they left it to Terminal and the diskutil command. I’m not sure why Apple removed this from the main Disk Utility. I’d avoid using this command unless the Disk Utility isn’t working for you. Without the GUI of OSX protecting you, it’s easy to select the wrong disk to erase. You can specify a 34-pass erase using the secureErase command. That’s an annoying change.Īgain, the command line comes to the rescue. If the disk is unformatted, you won’t be able to secure erase it. To access that option in El Capitan, you’ll need to select a Volume rather than a physical disk. Apple removed Secure Empty Trash and replaced it with Delete Immediately You can do this through terminal with the diskutil command. Securely deleting files: You don’t have to erase the entire drive to securely erase a file. In Lion and later versions, Apple removed that option and left you with a 7-pass erase as the most secure. Originally, Apple gave you a 35-pass method as the most secure erase method. In previous Disk Utilities, you could specify how you wanted a volume erased under options. I think it’s a little safer to run that program as a terminal is a powerful tool on a Mac. That free app does all the repair permissions behind the scenes. If you don’t like messing around in Terminal, MarcPac wrote RiparaCapo. Sudo /usr/libexec/repair_packages -repair -standard-pkgs -volume / If you like using terminal, this command will repair permissions.
