Nektony has launched Getting Ready for Yosemite (http://tinyurl.com/nj6mmff), a free step-by-step guide designed to help users migrate to Mac OS X Yosemite.
In addition, the company highlights Boost & Memory, Disk Expert & ClearDisk, three of its disk utilities that serve to aid Mac users prior to installing Yosemite for OS X. Boost & Memory is used to check the current memory usage and releases the inactive RAM.
Disk Expert helps to perform an inventory of disk space and get rid from useless and bulky content. ClearDisk is used for immediate cleaning a Mac hard drive of unnecessary files.
