Monolingual is a simple Mac program designed to help you permanently delete unneeded language resource files from your computer. By using this application, you can easily reclaim disk space on your local drives and improve the performance of your system.
The program features 2 main screens: one shows the available language resources files while the other one displays a list with all architectures from your Mac. All you need to do is to select the ones you wish to remove from your computer and the program will take care of the rest.
In my testing, the utility worked perfectly. It immediately completed the given task without displaying any errors.
The only thing I'd change about this application would be to add the "Select All" and "Select None" options.
Other than that, nothing bad can be said about this program. It does exactly what's being stated on the homepage of the developer, without slowing down the performance of your system. What's more, the application is free of charge. So, you should give it a try if you're looking for a quick and efficient way to deleted unnecessary language resource files and architectures from your Mac.
