MacのSymantec Endpoint Protectionは、OSをメジャーアップデートする場合は再インストールしないとダメらしい。

for a major update to Mac OS X on a client system (from 10.6.8/10.7.x/10.8.x to OS X 10.9.x (Mavericks) for example), we require temporarily removing the SEP client with the removal tool and cleanly reinstalling the compatible version after upgrade to avoid possible corruption to logs and other SEP components.
アンインストールはこちらの削除ツールから。
