Yank is a flexible and powerful tool for maintaining your Mac, but it's not a Swiss army knife. There are some things Yank is not currently designed to do.
OS Requirements · Creating Yank files requires Tiger and is not compatible with File Vault.
Downgrading · Yank is designed to remove software, not downgrade your Mac to an older version.
Shared files · Yank is not designed to manage files shared by multiple software installations.
Reinstalling · Yank is not designed to create Yank files when you re-install software.
Requires Admin · You should use Yank in an OS X account that has full administrative privileges.
Custom Installs · Some installers are not fully compatible with Yank and require some extra steps.
Disk Images · Use these instructions to install software from Disk Images with Yank protection.
Some of these limitations may be addressed in a future version of Yank.
