macOS 10.15 (“Catalina”) is the next major update to macOS, and we are working to provide full support for Catalina on Day 1 (if possible). We will update this page with any current status changes, betas, and information related to Catalina.

Catalina Changes

The Catalina update introduces new privacy controls for protecting data in Desktop, Documents, Trash and other folders. Apps that use the standard Open dialogs will not be affected since those are considered “explicit” opt-in from the user. Any applications that access files in these protected folders outside of the Open/Save dialogs will be prompted to allow access to these folders by macOS. Processes that are running as another user do not prompt the user for opt-in and are blocked from accessing the protected folders.

Catalina also requires all applications to be notarized by Apple prior to distribution or will be blocked from being installed.


Winclone needs privileged access to the Boot Camp partition to image and restore a Boot Camp partition. The image that is referenced on saving or restoring can be located in a protected folder. Since the privileged helper tool is running as root, rather than the user, it is blocked from accessing the image if it is stored in the protected location. To resolve this issue, Winclone is being refactored so that the privileged helper tool gives access to a non-privileged tool so that cloning and restoring does not fail if the image is located in a protected folder.

This is a major change to how Winclone works. We have updated Winclone and are currently testing to make sure it works on the different kind of Macs (EFI, Legacy, OS version, etc). The current build of Winclone has issues with accessing the files correctly and causes multiple errors.

Download a pre-release of Winclone 8 on the downloads page. Note that it is it currently in testing and should not be used on any machines with user data. If you have any issues, please submit them to the issues page.

See what is new in Winclone 8 at the What’s New in Winclone 8 page.

Issues submitted (all issue submitted to Apple are also submitted to the forums):

Boot Runner

Boot Runner displays its main window over the Login Window. Due to changes to the process that launches Boot Runner (launchagents), Boot Runner is not showing over the Login Window.

A fix has been identified and a beta is planned for August 15th.

SD Clone

SD Clone 3 has been tested and is shown to be compatible with Catalina. We will be notarizing the app prior to Catalina release. In the meantime, if you get an error message when opening the Disk Image, control-click and select Open.
