在點(diǎn)擊ok后，發(fā)現(xiàn)并不能保存。或者是保存了。但是最后面顯示 not install 重啟之后也并無1920*1080的HiDPI出現(xiàn)。
這就要提到我們開頭提到的System Integrity Protection SIP"系統(tǒng)完整性"了
我們只需要暫時(shí)關(guān)閉SIP，再次對軟件設(shè)置進(jìn)行保存，1920*1080自然會(huì)出現(xiàn)。
處于安全性考慮，關(guān)閉SIP設(shè)置成功后，建議再次開啟SIP，親測開啟后依然能夠做到正常使用，開機(jī)后自動(dòng)進(jìn)入1920*1080模式



終極解決方案：
2560 * 1440 + 開啟HiDPI
