My mac book pro used to be quicker.

On a pc I can clear the explorer cache, clean up the disc, defrag etc, what can I do on my MacBook Pro?

    How much free disk space do you have?

    What model Macbook Pro and what version of Mac OSX? how much RAM is installed?


    You can get the exact model by holding down the OPTION key and then, from your Apple menu, selecting either "System Profiler" or System Information," which ever is first under the Apple menu. That produces this screen:

    Post the code shown in the entry I've indicated with the the red arrow. The amount of RAM is also shown on that screen, indicated by the purple arrow.


    Do not post the serial number for security reasons, but include wheteher your MBP has a 13-, 15- or 17-inch dispaly (measured diagonally),


    With that info we can determine if the slowness is simply due to an old computer or due to a lack of RAM, and suggest possible upgrade paths.

    First, back up all data immediately, as your boot drive might be failing.


    There are a few other possible causes of generalized slow performance that you can rule out easily.


    • Reset the System Management Controller.
    • If you have many image or video files on the Desktop with preview icons, move them to another folder.
    • If applicable, uncheck all boxes in the iCloud preference pane.
    • Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
    • Check your keychains in Keychain Access for excessively duplicated items.
    • Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
    • If you're booting from an aftermarket SSD, see whether there's a firmware update for it.


    Otherwise, take the steps below when you notice the problem.


    Step 1


    Launch the Activity Monitor application in any of the following ways:


    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)


    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.


    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.


    Select the CPU tab of the Activity Monitor window.


    Select All Processes from the menu in the toolbar, if not already selected.


    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.


    Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?


    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)


    Step 2


    If you have more than one user account, you must be logged in as an administrator to carry out this step.


    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select

    View Show Log List

    from the menu bar.


    Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.


    When posting a log extract, be selective. Don't post more than is requested.

    Please do not indiscriminately dump thousands of lines from the log into this discussion.

    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

    You may want to look at this user tip article for some guidance:

    You haven't posted the information I asked for. If you determined on your own that iPhoto is causing the problem, then clearing the Safari cache won't have an effect. Rebuilding the iPhoto library might:


    iPhoto 6 and later: Rebuilding the iPhoto library
