MacBook screen white out? glitching?
hello first im korean so my english maybe not perfect sry :(
i bought used macbook pro 2015 15inch (since last macbook i bought wasnt able to fix)
i installed oclp (opencore legacy patcher) and bootcamp windows
everything works fine on windows but on mac os screen crackiling? glitching? like broken tv for 1sec and sometimes screen just turn to white or other color (gray,brown,rainbow etc)
i thought this happened after i install fmrte(i have to disable sip to lunch it) so i deleted it + return sip to normal but it wont work
have anyone know what cause it or how to fix it
thank u for reading long text
