Zwiftinstaller.pkg for Mac does not open

I have some issues with installing the zwift app on my Macbook Pro (Sonoma 14.4.1.)…

I download the Zwiftinstaller.pkg from the Webpage for Mac.

So far so good. But when I cklick on the Installer Icon, I get this failure message from my Mac…

Does Anybody have same issues or an idear how to solve it?
cheers mates

Hello @Gabor_von_Puskas welcome to Zwift forums.

Shuji at Zwift HQ here. Does your Mac hardware and OS support Apple Metal graphics?

An older Mac can be hacked to run Sonoma 14.4, but may not have the hardware to support Apple Metal API. Is this the case for that machine?

Hi @Gabor_von_Puskas, welcome to Forums. This is Juan from Zwift.

In addition, If you are unsure about if your hardware supports Apple Metal graphics, I’d like to suggest you take a look at this article.
