我需常用32-bit軟體,
故嘗試把新機內附的10.15取代成10.14。
步驟完全依照此連結:
https://www.imore.com/how-downgrade-macos
包括將T2晶片安全性降低到
「Medium Security」
「Allow booting from external media」
插入製作好的bootable「macOS 10.14.6 installer」USB drive,
開機時按option,可看到USB drive出現在選項內,成功選擇它,
但重開機後進入的畫面仍然是尋常的macOS Utilities,
只讓我Reinstall macOS Catalina,
完全看不到我的bootable USB drive有什麼作用。
(看起來不像是從外接USB開機。)
試了多次都這樣,
著急求助。
謝謝。
