一裝完 Snow Leopard，開機的歡迎畫面之後就出現這個：
Some of the software on your computer is incompatible with this version of Mac OS X. Because this software may cause problems with your computer, it has been moved. You can delete incompatible software that was moved.
Incompatible software on your computer was moved to a folder named "Incompatible Software" on your startup disk:
Parallels Desktop: version 2.5 of Parallels is not compatible with Snow Leopard.

Snow Leopard 手起刀落幫我踢走乞人憎的 Parallels！如果真係唔可以再用 Parallels（之前用過 Parallels 已經死機幾次），那就連帶裝在 Parallels 裡的 OS 都要被踢走，隨時取回 20GB 以上的空間，應該有一兩個 XP、2000 Pro、Ubuntu 同埋 Windows 7？
