In a folder named Disk Warrior Recovery Maker is a further utility. I had a USB drive in my pocket and connected that to a second port on the Mac. I always have a couple of flash drives handy and Disk Warrior can be installed to run with a basic version of OS X on such a disk. I followed the same process and installed Disk Warrior in Applications on that disk, but then was able to run the repair and rebuild processes on the main hard disk. I then started the Mac with an external hard disk connected via USB. Mine initially reported yellow: not perfect. This cannot be used to repair the start-up disk, but will show a green slider scale if all is well. Once that was done, running the installer quickly put a version in the Applications folder on my Mac. First, however, it is recommended that, working in the Admin account, older versions are deleted and the Trash emptied. Installing on the Mac was quite easy as Alsoft now provides an installer utility on the drive. I can also install Disk Warrior in some other ways: on my Mac, as I may want to check another installation, for example using Target disk mode on an external drive with OS X installed and on my own thumb drive, for emergencies. On newer Macs, the Apple logo appears, but nothing will happen. When finished it is a good idea to select the start-up disk, otherwise the computer may try starting from the flash drive. When the Enter key is pressed, Disk Warrior will start up. From there, the user types in the command /Volumes/DW/go. That starts the computer and the utility can be run from that external drive.įor those Macs that came with 10.7 or later - with the Disk Warrior drive in the USB port - users must start the computer in the OS X Recovery partition, then access the Utilities menu and start Terminal. There are several ways it can be used and I have reported at length on these on my website.įor older Macs, the utility can be run by starting the computer while holding down the Option key, then selecting the Disk Warrior Recovery drive. My update arrived last week and I have been testing this. The latest Macs no longer have disk drives, so it is now supplied on a flash drive. Recently Disk Warrior was updated to Version 5. The two best are Micromat's TechTool Pro 7 and Alsoft's Disk Warrior, which I have used since I switched to OS X in 2003. I have been told by users that there is nothing wrong with their Macs, when clearly there is.ĭisk Utility, ran from an external drive or from the Recovery partition, may fix many problems, some may be too severe, meaning a stronger utility is needed. While the system appears to behave, odd behaviour later on may indicate repairs are needed. A power cut, forced shutdown or other event may very well lead to an onslaught of problems. Despite my confidence in OS X, it would be wrong of me to suggest that Macs are perfect.
