    Anyone seen or is using this memory scrubber from MacKeeper? Think it is called MemoryKeeper, interesting item.

    I think you'll find that the overwhelming consensus here is to avoid MacKeeper, and anything related to it, like the plaque.

    It has been called, not entirely jokingly, a piece of malware.

    I'm sure others with more detailed knowledge will be along to comment.:D

    Not at all a fan of the MacKeeper, I use the OS based Utility and SpeedTools for repair and monitoring.

    That MacKeeper that replicates the Windoze thing advertised on the tube I completely agree is malware that enters your computer and one pays for that privilege.

    This memory scrubber seems to be a different animal.

    Omg, I've done more to clean my mac from having to see mac cleaner ads than mac cleaner software could ever do. Avoid at all costs.

    Doesn't this just purge your RAM which could easily be done in terminal anyway?

    As shrink stated, MacKeeper is unnecessary in general and any memory scrubber has little to no effect. You you really want to "scrub" the ram, then from the terminal type sudo purge.

    sudo purge?


    Is that the full path from the home directory? sudo to root, checked sbin no such command, man page shows nothing, also looked /usr/sbin? Please check I am interested and trying this sudo purge thing out.

    Thanks in advance,

    Not a boot

    If you type whereis purge, you'll get /usr/sbin/purge

    Please forgive the ignorance of the question, but since there is a discussion of Ram I thought I'd take the opportunity to bother you so I might learn some stuff.

    Why would it be necessary to purge RAM. My limited understanding is that when RAM is full, it "pages out" to make space available. What is gained in a RAM purge?

    Thanks...:D

    The idea is to free up inactive ram. OSX keeps some ram that was just used as inactive. For instance if you used MS word for a document, closed it out. The memory used by word would be marked inactive. If OSX needed more ram and none was around, it would grab it. On the other hand if you started word back up, it would mark those memory pages as active. It basically increases the performance. Purging it, marks is available.

    Here's Apple's definition of memory types

    I've been using Cocktail for at least 5 years.

    Great program. No malware and it has a nice GUI front-end for the tools.

    Thanks for mentioning this. I've previously been using icleanmemory since 2011, but I like this; it seems more current.

    I don't think this does what you think it does:

    OP has Snow Leopard, and that FreeMemory app won't help the OP. The app requires Lion (OS X 10.7) or higher. And, if you have 10.7 or higher, you have the purge command to easily use, rather than installing some random app that purports to provide access to a service that the system already provides.

    It does a fine job of freeing up a fair amount of memory which was being used by FS cache, something that will happen with people opening large files (Videos, photos, etc).

    Between running "purge" and exiting/restarting apps that have known problems with memory leaks (Firefox is a great example) it's possible to reclaim multiple gigs of memory.

    All that is moot if you still have tons of free memory, though.
