iTunes and iMove keep crashing

Hey everyone,

On my hackintosh, I can't run iTunes or iMovie. Gigabyte Z170X-UDF mobo, Intel Core i7-6700K, Gigabyte AMD Radeon RX460 graphics.

Both apps crash right shortly after startup. iTunes segfaults, iMovie throws another error:

Application Specific Information: [FFHGRendererInfo initWithLocation:] CGLSetVirtualScreen failed - didn't expect to get here. Investigate why this code ran: [FFHGRendererInfo initWithLocation:] CGLSetVirtualScreen failed: loc=1, ctxt=0x7f85e142d800, err=10008 -[FFRendererInfo initWithLocation:], /Library/Caches/com.apple.xbs/Sources/Flexo/Flexo-30323.5.7/framework/image/FFHGRendererManager.mm:341 abort() called 

Any ideas?
