Same issue. The Razer core doesn't work with all laptops. There has been some success with Dell XPS, but others have experienced issues. There are discussions on Razer's forums about what laptops work and which ones don't and currently there seem to be issues with any laptop that isn't a Razer.I meant, by running windows on Bootcamp ? Same issue ?
Plus there is going to be a bit of competition between makers of eGPU setups. See what MSI is doing compared to what Razer is doing.
