How to solve Yosemite massive memory leak? I am experiencing a massive memory leak in Mac OS X 10.10.2 (14C2513). I have 16 GB of RAM and the used memory rise to circa 15 GB in ~3 hours. Top applications usage is relatively low, circa 200 MB per application (10 top applications).

I solved it only shutting down the system.

Is there any update for this?
OS X (and all modern operating systems) is designed to use all of the memory that's available, for file caches if it has no better use for it. That's not a problem, since memory used for file caches is still available for applications to use.
