自從開始用了MacOS以後，其穩定性，基本上令人非滿意；但，還是發生了一些，不該發生的事，因些順便整理下來，在MacOS ，一些曾經遇到的疑難雜症，分享一下。

看錯誤訊息是NVME的問題，用相關錯誤關鍵字在網路上查詢了非常久，幾乎翻遍了國外相關資料，沒有有效的解方，後來發現除了換掉SSD，基本無解。
把Intel 660p SSD換掉，改用Samaung SSD。就解決了。
通常在大約開機後約5-10分鐘或半小時後發生，系統莫名關機，畫面變成純黑，以為關機了，但似乎又不是，因為按下power鍵，沒反應；要按5秒鐘，才會直接關機，接著再按一下power才能開機。完全查不出任何問題，基本上一開始以為是主機板快要壞了或什麼嚴重的問題吧！而且這臺iMac已經很舊了，所以不打算維修。
曾經嘗試過的方法：
- 將一些開機後自動啓動的常駐程式關掉。似乎有效，但沒出久又出現一樣狀況。
- 開啓Firewall，似乎真的有效，沒有再發生；但仍不確定是不是真的原因。也許拔掉網路線，也可以確定是不是被攻擊造成的，但當時沒有這樣測試。
- 也有可能是更新完系統程式，才造成的！不確定。
- 剛好新的更新系統程式來了，更新完後，就好了，沒有再發生。
MacOS, iphone, ipad突然之間接力(HandOff)功能失效怎麼辨？
這個功能實用性質非常高，網路上有許許多多常規的解決方法，甚至包括英文的解法，我都試過，但都無效，我的測試方式是兩兩分別測試；後來試出來，分別將各個設備的Handoff功能，作一次關閉及開啓接力功能，再重開機就正常了。
註：若單純只有關閉再開啟接力功能或只有重開機，都無效。
如何完整的移除MAC版office授權檔案？
為什麼會有這個需求呢？例如：從一般版本轉換到office 365版本。
