Royal TSX and macOS 10.12 Developer Preview

Hello early adopters,

now that the first developer preview of the rebranded macOS 10.12 Sierra has been released, we wanted to give you a quick update on Royal TSX’ compatibility with the new OS.

Like with every beta OS, we want to remind you that we do NOT generally support beta/developer preview releases and we do NOT recommend to install OS betas if your daily workflow depends on Royal TSX. However, it’s obviously in our own interest that our products are compatible as soon as possible.

Right now, only our Royal TSX V3 beta is compatible with the first developer preview. The current stable release of Royal TSX (V2.2.4) does NOT run on the developer preview and will crash when launched! The reason behind this is that Apple removed certain features from the OS that Royal TSX depended on. We plan on making the stable release compatible with the new OS once the first public beta of macOS 10.12 is out.

The first stable release (V2.2.5) that supports macOS 10.12 Sierra is out now. As usual, you can get the update on our website.

Our latest Royal TSX V3 beta release which is compatible with the developer preview is available here.

For any feedback about Royal TSX V3 beta or compatibility issues with the developer preview, please don’t hesitate to contact us through our support portal.

    Thanks for the update.

    I enjoy Royal TSX every day. It’s insanely functional, fast, beautiful, and it looks awesome beside Mail, Pages and Safari. You’re doing a great job.

    May I ask, what are those features that Apple removed from the OS?

    Thanks again.

    @Gonzalo: Thx for all the kind words – much appreciated!
    The issue that makes the app crash at launch is related to the new logging system in Sierra.
    See this developer document for more information:

    I’m still not 100% sure why it crashes but the workaround that I implemented is quite simple and effective. Now I’m waiting for a new 10.12 build that hopefully restores the old functionality.
