Bug prevents the productivity suite from launching

Oct 23, 2019 07:20 GMT  ·  By

Operating system updates, be they for Windows, Linux, or macOS, sometime cause app issues on the devices where they are installed, especially if the apps in question haven’t received updates in a long time.

This isn’t necessarily surprising, as companies like Microsoft and Apple continue improving their operating systems with new features, and without the necessary updates and optimizations, app could eventually fail to work correctly on a series of devices.

In fact, app compatibility issues have always been the main concern, and this is the reason app updates are must-haves these days.

But there are moments when compatibility isn’t the one breaking down apps, but rather blunders that the developers of the operating system updates do in the first place. One such example is Apple, as the latest macOS update makes it harder (not impossible, though) to run the LibreOffice productivity suite.

As many of you know, LibreOffice has long been the main alternative to Microsoft’s more expensive Office productivity suite, and this product is being used not only by home users, but also by organizations and even state agencies across the world.

Unfortunately, however, devices updated to macOS 10.15 Catalina might be unable to run LibreOffice due to what The Document Foundation (the makers of LibreOffice) describes as an issue with the developer not being verified.

“Mac apps, installer packages and kernel extensions that are signed with a Developer ID must be notarized by Apple to run on macOS Catalina. Although we have duly followed the instructions, when users launch LibreOffice 6.3.x – which has been notarized by Apple – the system shows the following scary message: LibreOffice.app cannot be opened because the developer cannot be verified,” the company explains.

Basically, once you see this message on the screen, there are only two options that you can use, namely Move to Bin and Cancel. None allows you to bypass the warning and launch LibreOffice.

Fortunately, there are two workarounds, and both allow you to run LibreOffice normally until The Document Foundation is working with Apple on resolving the problem.

The message users could get after the update

First and foremost, there’s the more convenient solution that only requires a few more clicks:


Right-click/Ctrl on the keyboard LibreOffice icon > Open
If you do this, you should see a message that actually includes a third option called “Open” that lets you run the productivity suite despite the warning.
macOS cannot verify the developer of LibreOffice.app. Are you sure you want to open it?
The second workaround requires a few more clicks, albeit it can also be used by pretty much anyone on macOS. What you need to do is follow the next steps:
Launch LibreOffice > Get original warning > Click Cancel > Apple menu > System Preferences > Security & Privacy > Open Anyway for LibreOffice warning
“We will try to sort out the issue with Apple, in order to avoid similar issues in the future with macOS Catalina,” The Document Foundation explains.

At this point, there’s no ETA as to when a fix could be released to let you launch LibreOffice on macOS Catalina without having to turn to these workarounds, but it shouldn’t take too long before it lands because TDF is already a trusted developer.

The same issue affects all versions of LibreOffice, including the 6.4. alpha builds, so you need to apply the workarounds mentioned above regardless of the version that you installed on your Mac. We’ll continue to monitor how things improve this regard and let you know when the fix is no longer required.
