my mac since one week is VERY SLOW. The MB free are 350 now. After cleaning they become 1000 but after few minutes they fall down to 2/300 AGAIN.

It's impossible now to work with.

Thank you for helping!


Mac Pro, OS X Mountain Lion (10.8.1)

    If you only have 350 MB of free space this is your problem... you need at least 15 to 20 GBs for OS X to perform as expected...

     

    You need to start deleting items to create more Hard Drive Space...

    This was not at all obvious from your first post...

     

    Moving on...

     

    You may need to add more RAM to your Mac... How much is Installed at the moment...

    Telling people and that means complete details. Less than 6GB, not enough no matter what. 2008 use 8 DIMMs. What you run and what you did to clear RAM, what you did a week ago.

     

    Too often "Mac Pro"turns out to beMacBook Pro too, makes slighly different machine and type of user.

    yes sorry about it. 2+2 but the thing is that until one week ago all was ok and the mac was normally fast-

    one week ago I used the app twin to cancel the double files. Then I added the apps evernote, free memory and facebook

    Use this arcticle to inspect your memory usage:

     

    Using Activity Monitor to read System Memory and determine how much RAM is being used

     

    Start the Applications you normally use at the same time.

     

    How much of the pie is Green?

    How much is Green plus Blue?

     

    How many PageOuts since last Restart?

  • nicolakk Level 1 Level 1 (0 points)

    hi Grant.

    the green is now 328 MB

    the blue (inactive) is 1,24MB

     

    What is page out sorry?

    What is interesting is the relative size (in fractions of a pie) of these colored areas. The chart from the article shows a quarter of a pie of green, a good amount. 

     

    We worry when the green becomes an insignificant sliver, say less than 1/8 pie.

     

    Page out is a number (not a graph) just to the left of the pie. It is also described in the text of the article. It tells you how much the Hard Drive is being used to give the appearance of "infinite" memory.

    4GB is very light on RAM and I would avoid - you don't need or want Free Mem.

     

    Still not telling what model/year, 2008?

     

    If all you do is chat, email, no graphic editing or heavy lifting.

     

    You know each new OS makes more d3mands on hardware, sometimes a browser is going to hold onto 1GB RAM - and need to purge caches.

     

    add 4GB RAM. helps and can't hurt and just let OS X run. Might want to move system on a new drive, move data to a new drive also, keep them separate.

    So that means you have 4 GB of RAM...

     

    Would suggest going to 8 GB.. if not more...

     

     

    See this Link to check which RAM is for your Mac...

    It is Important to get the Correct and Matching RAM

     

     

    For best performance, fill all memory slots, installing an equal memory module in each slot.

     

     

    That site also has videos on how to Install RAM should you need it...

    thanks. My mac is model 2011.

  • The hatter Level 9 Level 9 (60,785 points)

    There really is no 2011 Mac Pro, and even the refreshed 2012 are all MacPro5,1 and 2010, nothing changed since. Well, price of memory which has come down hugely.
