Lock-UnMatic for Mac helps you unlock a file that refuses to be renamed, moved, or deleted. It shows you the reason why a file is locked and allows you to unlock it or kill the process responsible for locking it.
Unlock files quickly and easily: With Lock-UnMatic for Mac you only have to drag and drop the locked file into the app window, which will automatically show you the processes or running applications that are using it.
Kill processes from within the app: Apart from showing you the full path to where the file is located and which application is using it, this app also allows you to kill processes with just the click of a button.
May bypass access-rights limitations: You may unlock files even if you don't have sufficient access rights.
LGPL Freeware: This app is released under GNU Lesser General Public License so developers and companies can integrate it with their own software.
Your Mac's Activity Monitor may already be enough: This app acts basically as the Activity Monitor that filters the specific processes responsible for locking a particular file. If you understand file associations and the nature of processes well enough, you don't really need this software.
More convenient as a contextual menu function: This is not a major drawback but Lock-UnMatic for Mac would have been easier to use if it were available in the contextual menu.
Lock-UnMatic can help you address problems with locked files in a few easy steps. However, if you're an experienced Mac user, you could do without it, especially if you are familiar with the processes or applications that run in your system.
