Umyalelo ofakwe kwi-OS X Yosemite Terminal uvumela abasebenzisi abakwi-beta ukuba basebenzise 'imowudi emnyama' okanye njengoko beyibiza njalo, iNdlela eMnyama kwinkqubo yokusebenza. Le yinto abangazange bayitsho kwi-WWDC yokugqibela kaJuni, kodwa ivumela umsebenzisi tshintsha inkangeleko entsha ye-OS X ngeethowuni ezimnyama.
Asazi ukuba iNdlela eMnyama entsha kwi-OS X Yosemite iyafumaneka kuhlobo lwayo lokugqibela, kodwa kuya kuba kuhle ukuba bayishiya ngokusisigxina kwabo basebenzisi abafuna ukubona iDock kunye nebha yemenyu ephezulu ngokujonga okwahlukileyo. Olu tshintsho kuyilo lufunyenwe ngumvelisi uHamza Sood kwaye ukuba ungomnye wabo wenze isahlulelo ukuba nenkqubo yokusebenza efakwe kwi-Mac yakho, ngoku ungayivavanya ngokufaka lo myalelo ulandelayo. 
Ukwenza le ndlela isebenze kufuneka ukuba siyifakile I-beta yamva nje ekhutshwe yiApple kwaye uvule iTheminali ngokukopa lo mgca wokuyalela:
Ukungagqibeki kwesudo kubhala / iLayibrari / Ukukhetha / .GlobalPreferences AppleInterfaceTheme Dark
Nje ukuba eli binzana likopishwe, sicinezela ukungena kunye emva koko kuya kufuneka sivale iseshoni okanye siqale kabusha iMac ukuze le miphumo yobumnyama iqale ukusebenza.
Ukuba yintoni sifuna ukubuyela kwi-OS X Yosemite ngeetoni ezikhanyayo okuvela kuyo, konke ekufuneka sikwenzile kukufikelela kwiTheminali kwakhona kwaye utshintshe igama eliMnyama ukuba likhanye ekupheleni komgca wokuyalela kwaye yiyo loo nto. Ingxaki ngohlobo olumnyama kukuba isicatshulwa simnyama kwicala lasekunene kwimenyu yebar kwaye ngekhe ubone nto kuba yonke into inombala ofanayo.
Obu buchule bokutshintsha inkangeleko ye-OS X ibunika ukubamba okuhle, kodwa ayisiyonto esinokuyisebenzisa kakuhle ngenxa yomxholo webar yemenyu. Kwelinye icala kulungile ukuba iApple ivumela ukutshintsha imbonakalo yoqobo ye-OS X ngendlela elula, kwaye andikhumbuli nayiphi na i-OS X yangaphambili evumela olu tshintsho kwiTheminali.
