至從前幾天把MBP升級到10.8.4後，發現常常當機，特別是只要跑到吃顯卡的遊戲就當機，後來找了顯卡硬體測試軟體 cinbench想說來測試一下，發現問題還真的很嚴重，幾乎每測必當機，下面是我的kernal painic 檔案，可以從你的應用軟體中，工具->叫出"系統監視程式"找看看有沒有你當機時間點，檔名含有kernal panic的檔案，內容格式如下，然後找到下面的關鍵字，System uptime in nanoseconds: 1026462746290
就是會使用些很大時間，接下來的哪一兩個程式應該就是有問題的，以我的例子而言，是一個叫做key4remap4macbook，請看下面付的檔案，被標記橙紅色的部份，我把它移除後，重新開機就一切正常了，或者你也可以在terminal 直接使用下列的密令，查看是否有非apple的keytext在開機時會被load進系統
＃kextstat -kl | awk ' !/apple/ { print $6 } '
kextstat | awk ' !/app/ {print $6} '
