    Hi all,

    Since installing Mojave, after disconnecting an external monitor from my MacBook pro, whenever an application requires the dedicated graphics card the screen just goes black.

    After a restart the problem is fixed until an external monitor is plugged in & out again.

    Has anyone else had this issue?

    Do you have your displays set to mirror or external only?

    I usually work with both screens, non-mirrored. The external monitor is HDMI connected.

    I've not found anyone else with this issue so I guess I'll have to try a re-install to see if that helps!

    Not criticising you, and can understand why your about to do it, it seems awfully “final” to have to do a clean install every time as the only solution to fix something. Mojave shouldn’t need drastic measures to sort something as simple as connecting to external monitors. Just saying.
