![]() CCC will automatically create System and Data volumes on the destination as required to support APFS volume groups.If any scheduled tasks are disabled in this manner, CCC will be opened automatically on startup and these concerns will be raised to your attention. When you upgrade to macOS Catalina, any existing backup tasks that reference your startup disk and a non-APFS destination volume will be disabled and flagged for review. ![]() When you proceed with the task, CCC will automatically convert the destination to APFS (when possible). When cloning a macOS Catalina system volume, CCC will inform you of this requirement and request your permission to allow conversion of an HFS+ formatted destination to APFS. macOS Catalina requires APFS, it cannot be backed up to a volume formatted with Apple’s legacy HFS+ format.The logistics of booting macOS are a bit more complicated in macOS Catalina, but we’ve risen to the challenge, CCC supports it 100%, and nearly all of these complications are dealt with automatically. For most people, that’s all you need to know, and you don’t have to make any changes to your current tasks to accommodate the upgrade. CCC will make bootable backups of macOS Catalina startup volumes.Added a proper accessibility label to the task status icon in the Task History window. Addressed some minor accessibility annoyances in the CCC License window.Failure to mount an encrypted volume attached to a remote Mac is now handled with a password request and the task’s destination specification is updated accordingly.Addressed an issue in which a remote Mac could go to sleep between CCC’s archive management and file copying requests.CCC now proactively warns against cloning a volume whose operating system is newer than what the Mac is currently booted from.Previously we were simply marking the task dirty, and many users found that behavior disconcerting. Modification of the name of a source or destination is detected and presented as a review item to the user.This resolves a potential vulnerability in which an application masquerading as CCC could make requests to CCC’s helper tool. CCC’s privileged helper tool now proactively verifies the code signature of any client that attempts to connect to the helper.CCC offers more helpful advice in cases where snapshot creation fails due to the destination being a slow, rotational device and also in cases where encryption conversion is preventing the creation of snapshots.Users are still welcome to manually enable snapshot support on any volume – simply click on the volume in CCC’s sidebar and flip the switch to “on”. We have been underwhelmed by the performance of APFS on rotational devices, particularly with snapshot-related activities. ![]() CCC no longer automatically enables snapshot support on APFS-formatted volumes unless CCC can positively determine that the underlying device is an SSD.Changed the encoding of postflight emails that are sent by CCC to “quoted printable” (from UTF-8) to address an obscure edge case on some systems.Added a button to reveal the password that you’re typing into the Email Settings password panel.Corrected the read/write rate calculation for non-APFS-Fusion volumes.Addressed an issue introduced in 10.14.6 that prevents the removal of snapshots via CCC’s Disk Center (it does not affect the automated removal of snapshots that occurs when backup tasks run).Version 5.1.10: Changes not specific to macOS Catalina: Available in English, German, French, Dutch, Italian, Japanese, Spanish. ![]()
