Isimo sengqondo sika-Apple kuyo yonke le nkinga sibonakala siyindida eyodwa enkulu. Le nkampani ayinikezi kuphela abaqaphi bangaphandle abangama-4K nabangu-5K abavela kwa-LG futhi yabakhuthaza kakhulu ngemuva kokwethulwa kwesizukulwane esisha seMacBook Pro, kodwa nayo ngokwayo inama-iMacs kuphothifoliyo yawo angenaso isibonisi esinesixazululo ngaphandle kwe-4K ne-5K. .
