Apple 為 140W USB-C 電源轉接器推出 1.4.90 韌體更新
Apple 於 2026 年 9 月 8 日推出 140W USB-C 電源轉接器的 1.4.90 韌體更新；更新會在轉接器連接至 Mac 或其他裝置後自動安裝，且無法手動套用。
情報判讀
訊號摘要
Apple 未提供這次韌體更新的版本說明，因此目前無法確認 1.4.90 包含哪些內容。使用者不需要透過手動程序套用更新，轉接器會在連接至 Mac 或其他裝置後隨時間自動完成更新。
為什麼值得注意
這次更新不提供可見的變更內容，也沒有手動套用方式；140W USB-C 電源轉接器的使用者只能讓轉接器在連接裝置時自動處理更新，無法事先確認 1.4.90 解決或加入了哪些項目。
