时间胶囊 Time Capsule 中的备份无法删除

手动删除 sparsebundle 时弹出提示框口

The operation can’t be completed because the item “bands” is in use.

按如下方法解决：
try right clicking the file, go to "show package contents", then select everything and delete while holding the option key. after that you should be able to delete the sparse bundle.
