Require administrator authorization to make changes to tasks and to run or stop tasksĬCC identifies a subset of activity that causes changes to CCC tasks and preferences or that require access to privileged data (e.g. If you cannot rely upon the physical security of your Mac to prevent someone from using your Mac, you can use the information below to apply a stricter security policy to CCC. If you leave your system unattended with an admin user logged in, someone with physical access to your system can modify or run your CCC backup tasks. While this new configuration is easier to use and has been requested by countless users, there are situations where this configuration is not appropriate. Rather than requiring you to enter admin credentials every time you want to run a task or make changes to a task, CCC 4 now only requires you to authenticate once when CCC is initially installed. If you cannot, you will have to back up the other data on your destination disk and repartition the disk using the GPT partitioning scheme to get a bootable backup. If it can, you're all set and you shouldn't be bothered by the warning again. If you cannot repartition the disk because you already have a considerable amount of data on the disk, proceed with the backup task, but confirm whether it can actually boot your Mac. If you haven't copied any data to the destination disk, then take the time to repartition your disk using the GPT partitioning scheme (see above) so you have a sanctioned, bootable backup volume. Here's what you need to do about the warning We expect that Intel Macs will eventually drop support for booting from APM-partitioned disks. As the warning indicates, you may have difficulty booting from the destination volume, but it may work just fine. Because Apple no longer supports the APM partitioning scheme, CCC will warn you if your destination disk is not partitioned with the GPT partitioning scheme. ![]() Note, however, that Apple only supports booting an Intel Mac from a disk partitioned with the GPT partitioning scheme. ![]() Intel Macs can boot from a disk that is partitioned with either the APM or GPT partitioning scheme. PowerPC Macs could only boot from a disk that is partitioned with the APM partitioning scheme. A disk can be partitioned as "Apple Partition Map" (APM), "GUID Partition Table" (GPT), "Master Boot Record" (MBR), or the Fdisk partition scheme. Every disk has exactly one partition scheme.
