Autodesk軟體更新速度有時難以讓人接受，以cad和maya為最。CAD還好自帶刪除，maya就要自己手動刪除了。如果刪除不乾淨重灌就會有問題。
刪除maya 2012為例：
許可資訊 /Users/username/Adlm
1. 刪除軟體主目錄，如果你只裝了maya, 直接丟垃圾桶吧。
    /Applications/Autodesk
2. 刪除Backburner
    /usr/discreet/backburner
    /usr/discreet/lib32/backburner
    /Library/LaunchDaemons/com.autodesk.*
3. 刪除Network Licensing Manager [NLM]:
   /usr/local/flexnetserver
   /Library/StartupItems/adsknlm
4. 刪除 & 備份licensing檔案/目錄:
   網路版本(Network)
          /var/flexlm/maya.lic or adsk_server.lic
   獨立版本(Standalone)
          /Library/Application Support/Autodesk/Adlm
          /Library/Preferences/FLEXnet Publisher/FLEXnet/adskflex_00691b00_tsf.data
          /Library/Preferences/FLEXnet Publisher/FLEXnet/adskflex_00691b00_tsf.data_backup.001

注：如果你有安裝CAD軟體就要注意，刪除standalone licensing檔案會受影響。所以你要用刪除CAD後再重灌。如果你不想重灌CAD可以參考

另：有些目錄是隱藏的，可以用終端命令:open開啟。或者在Finder直接“前往資料夾...”

這個是AutoDesk的說法

Uninstall Maya on Mac OS X or Linux

To uninstall Maya on Mac OS X

1. Navigate to the Maya directory (by default, /Applications/Autodesk/Maya2013/).
2. Drag the Maya2013 application to the trash.
3. Open a Terminal window and execute both of the following commands, where <productKey> is your product key:

   adlmreg –u S <productKey> 2013.0.0.F
   adlmreg –u N <productKey> 2013.0.0.F

   This ensures that product information is properly removed from the ProductInformation.pit file.
