    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.

     

    • 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.

     

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

     

    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.

     

    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 can answer in Italian if you prefer.

        

    Please read this whole message before doing anything.


    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

    The purpose of the test is to determine whether your problem is caused by third-party system modifications that load automatically at startup or login.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
    • Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    • When you see the gray Apple logo, release the shift key.
    • If you are prompted to log in, type your password, and then hold down the shift key again as you click  Log in.
    *Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.

    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.  The next normal boot may also be somewhat slow.

    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?

    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

    Hello thank you very much Davis,

    I did the test you wrote to me but I did not know if the test is only riavvirae the mac in safe mode and use it normally ..

    I did what you have indicated,

    I have a password input because I use a Mac for work,

    when I rebooted in safe mode in the upper left was written in red "safe mode" and when they came in with the password while having clicked the button marked shift seemed no more ..

    the mac in safe mode was very slow but not slow yesterday in which I was crazed ..

    The screen is loaded very slowly as if the graphics card was almost enough I also noticed that for example using just facebook ram free even came to 5 mb .. (I have 4 gb of ram ..) I am attaching a picture of the ram from monitoring activities even if at that time the free RAM was greater ..

    Yesterday I also uninstalled Adobe Flash because I thought it was the software to give me problems but in the end continued to be slow ..

    look your news

    I'm a little depressed ..

    thanks

    rohl70

    If I understand you, then, everything is normal when you don't launch Safari. With Safari running, everything slows down, even in safe mode. Is that correct?

  • 11. Re: macbook pra 13 lento slow
    rohl70 Level 1 Level 1 (0 points)

    Yes with safary is tto slowly,

    on teh monitor activity i see that

    safari web content take much then 1 gb at a time

    and safari take much then 400 mb..

    i don't use tha mac without safari so i see that using Chrome for facebook

    do the mac not too slow..

    now i open Archicad too and the free ram is like 5 mb at a time..

    i don't know if i can explain right..

    I suggest that you write in your native language. Please use simple words and check your spelling and grammar.

    It is with safari is very slow,

    I saw that on the monitoring activities

    sometimes safari web content arrives at times in a real memory of more than 1 gb

    and that safari sometimes come to a real memory of more than 400 mb

    I have not tried to use the macbook off safari

    But I saw that using chrome for facebook does not create those delays had incredible safari for using facebook ..

    also i use archicad for work and sometimes free memory monitoring activities also came less than 5 mb

    Back up all data. Uninstall or disable "Little Snitch" according to the developer's instructions. Reboot and test.
