Casper 8 Startup Disc (Boot CD) Full Version

By default, recovery mode is preconfigured to boot into Disk Utility or to macOS Recovery. If you are prompted to press any key to continue after booting in recovery, you can press the key to return to your Startup Disk. You can boot into a recovery build of macOS from the Startup Disk to perform an upgrade or clean install. You can create a startup disc from the recovery partition on your Mac, or you can select the macOS version you wish to return to.

Once you have finished installing macOS, you can reboot your Mac to boot macOS or macOS Recovery. If you are using the Mac App Store to do the install, you will need to boot into Recovery using the Startup Disk to proceed with the installation. If you are going to boot directly into macOS, you will need to boot into the Macs native bootloader and add the Startup Disk to your boot configuration. See this support document for more details.

If you have a large amount of data and need to get this off the startup disk, then youll want to use create an archive of the entire startup disk, you can use any of the other tools that have been created to help you optimize the startup disk, or use the commandline tools available.

Below are available commands that you can use to rectify the problem, if you have problems getting to Safe Boot press and release the CMD key to enter safe mode. If you cannot boot into safe mode when you select Apple>Restart, then use the Create Archive and select Safe mode, I’m showing you another way to enable Safe Mode by using a different text editor, select this question and the answer from @snoramoe is showing you how to enable the Safe boot option, In order to get to the command line (which also is very important if you ever need to recover after you delete files) you need to press and release the CMD key while booting, and when that happens you will see the command line. Then to continue without booting into safe mode youll need to drop into single user mode, then to continue, you’ll need to start up again in normal mode. Now it will all be clearer.

The find and xattr commands will report on any file attributes on your startup disk, this find command will report the xattr file attributes, including the permissions, and ownership. For example, when a file is not readable but is executable, then the xattr attribute is not writable. However, the find command will report that it is writable because it was created by ‘The Finder’ even though it is not and has not been written to by the Finder.
The menu items are not that intuitive. Theres actually a few options in startup disc. If you’re booting from a startup disc: Select “Remove disk from startup”. This clears the startup disks. This is safe to do if you don’t have a lot of important files or programs on your startup disks. Select “Browse for startup disk” if you want to use a specific startup disk. Note that this doesn’t work if you use all the startup drives or hard drives on your system, because in this case, the startup drive can’t be determined. Select “Remove” to remove all startup discs. This will nuke the entire list of startup drives, and your Mac will not be able to boot. This is not what you want. This is dangerous. Don’t do this unless you know what you’re doing!
It’s a good idea to only run live CDs and DVDs from trusted sources. This means that you can’t download Casper directly from the web, or from a dubious or unknown source. If you want to be extra safe, you can use a Certified Live Distribution to download Casper.
