EaseUS Software has released MacCleaning, an all-in-one menu bar utility for cleaning your Mac junk files, showing disk space available, warning when the disk space is running low, ejecting drives, and more.
With one click you can start a process to remove the junk files like system caches, system logs, user logs, user downloads, trash, Safari cache, etc. The free space of system drive will be pinned to the menu bar, which allows you to react in advance before the drive is full.
Two versions of MacCleaning are launched, MacCleaning (http://www.easemac.com/products/maccleaning-free.htm) and MacCleaning Pro (http://www.easemac.com/products/maccleaning-pro.htm). MacCleaning Pro ($9.99) has all the features of the free version and enables you to customize the space value to display a warning and eject all the mounted devices with a click.
