Mac Book Pro runs slow

I have a mid-2009 Mac Book Pro. Safari runs poorly. I put something in the search bar, it sits, pauses, disappears, then reappears, then searches fairly slowly. I ran EtreCheck on it, here's the report. Any suggestions are welcome.
Problem description:

Some of your user files (not system files) have incorrect permissions or are locked. This procedure will unlock those files and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Back up all data before proceeding.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
Start up in Recovery mode. When the OS X Utilities screen appears, select
          Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
resetp
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
           ▹ Restart
from the menu bar.

    There is no need to download anything to solve this problem.
    You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
    Back up all data before making any changes.
    One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
    If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
    Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
    Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
    In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere  should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
    Still in System Preferences, open the App Store or Software Update pane and check the box marked
              Install system data files and security updates (OS X 10.10 or later)
    or
              Download updates automatically (OS X 10.9 or earlier)
    if it's not already checked.

  • Mac book pro running slow and word and excel from Mac not opening

    Mac book pro running slow and word and excel from Mac not opening

    Call it Monday morning humor.... ALL the MacBook Pro owners we see asking the same thing (more than once a day, too) are slower since 10.10.x so we can assume something. Heard the very same story with every new OS in the past decade from laptop owners, heard a lot especially with Snow Leopard back in Aug-Sept 2009.
    A new OS goes better if you do a clean install / checked Roaringapps.com for compatibility / wait for vendors to have updates
    About the only things that can be done in addition - if you have like many posting those symptoms have minimal 4GB RAM is to upgrade to 8GB+ and throw in a new 250GB+ SSD (the most recent MBP have to be bought with and cannot add RAM later).
    Even the MacBook Air 2014 though with 4GB RAM have PCIe-SSDs that helps, plus 4th gen Intel i5's and an IG of 5000 or later all help.
    Try including more details. Model year and configuration at least.

  • Mac book pro running slow with lion

    My Mac book pro is running real slow since upgrading from leopard to lion. Takes up to a minute or more to boot up and open some programs like I Photo.

    Perhaps you need more RAM or you do not have enough Free Space on your Hard Drive...

  • My late 2008 mac book pro runs slow and freezes

    Hi, there! I have a late 2008 mac book pro and few months ago I upgraded the operating system from Snow Leopard to Mountain Lion. Since then my mac book often freezes, it is much slower than it was with Snow Leopard and the most annoying thing of all, is the almost inevidable freezing of the toolbar (where language selection, date, clock and other useful tools are located)
    I was wondering if someone has experienced similar issues with his Mac Book Pro when upgraded to OSX Mountain Lion and if someone knows if and how this issue can be resolved?
    Thank you.

    I have the same problem. Up until 2 days ago my MacBook Pro was running fine, then suddenly things started going wrong. I am using mac os x 10.6.7 as well. Does this have something to do with any firmware updates.
    Any help/ suggestions welcome.

  • Mac book pro running slow since installing yosemite

    hello
    since I have installed yosemite on my 2012 mac book pro most things are VERY LAGGY and slow things don't close I have to hard power the machine down is there any way to do a system restore back to mavericks ??
    this yosemite is crap
    mick

    Hi ..
    Make sure to quit all open applications prior to shutting down your Mac.
    Not enough free storage space can slow your Mac down.
    Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage. Make sure there's at least 15% free disk space.
    OS X Tips Where did my Disk Space Go
    If there's enough free storage space, open System Preferences > Users & Groups then select the Login Items tab. Remove all items there.
    Same with:   HD > Library > StartupItems
    Then restart your Mac.
    And check the startup disk.
    Launch Disk Utility located in HD > Applications > Utillities
    Select the startup disk on the left then select the First Aid tab.
    Click:  Verify Disk (not Verify Disk Permissions)
    If Disk Utility reports errors, restart your Mac while holding down the Command + R keys.
    From there you should be able to access the built in utilities in OS X Recovery to repair the startup disk and restore OS X.

  • Mac Book Pro runs slow after Lion 7.2 upgrade

    Ever since I downloaded the Lion 10.7.2 my MBook Pro runs SLOW! Any thoughts or suggestions?

    Reinstall preferably from scratch:
    Install or Reinstall Lion from Scratch
    If possible backup your files to an external drive or second internal drive.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Erase the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
    Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Install button.
    Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

  • Mac Book Pro Running Slow since installing Mountain Lion

    Since I downloaded Mountain lion this summer my MAc Bok has been running slow and running hot.  I am not sure what to do.  I checked my hard drive is only 4GB and I may need to upgrade it.  But waht else can I do?
    Saran

    You need at least 20 GBs of free space on your hard drive and at least 4 GBs of RAM.
    Things You Can Do To Keep Your Computer From Slowing Down
    If your computer seems to be running slower here are some things you can do:
    Boot into Safe Mode then repair your hard drive and permissions:
    Repair the Hard Drive and Permissions Pre-Lion
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Repair the Hard Drive - Lion
    Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Restart your computer normally and see if this has helped any. Next do some maintenance:
    Suggestions for OS X Maintenance
    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
    I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
      1. Carbon Copy Cloner
      2. Data Backup
      3. Deja Vu
      4. SuperDuper!
      5. SyncTwoFolders
      6. Synk Pro
      7. Synk Standard
      8. Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac maintenance Quick Assist.
    Referenced software can be found at CNet Downloads or MacUpdate.
    Additional Hints
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
    Check for applications that may be hogging the CPU:
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

  • Mac Book Pro running slow since Yosemite

    Well sine installing Yosemite, my Mac is slow. I am not impressed with the new look and feel. All the minor changes seems to make my life and Mac more difficult. I have checked my storage space and I have lots of memory to be running Yosemite. I have checked the user group settings to ensure there are no programs running at start up, which use to be instant now takes a few minutes when turning on and I have to sign into my Mac. If I knew it was going to be like this I would have just installed Windows with the hassle.
    I would like Maverick back..... or any better suggestions as I am LOVE my Macbook pro with retina display and want it back to working in prime condition prior to the Yosemite.
    Here as some of the issues:
    Turn on time 1-2 minutes plus I have to sign in
    Safari s...l.....o.....w
    Most programs are slow or shut down randomly such as pages and keynote
    Synching with iPad and iPhone not always quick even know everything is cloud based (i.e.. took a picture the other day on iPhone, show on iPad still not on my laptop)
    Just hate the look - but I guess I can live with that... or if someone knows how to make the tool bar clear again that would be great, not happy with the white.
    These are just the surface of my issues, but the speed is the main item for all programs right now.

    Download and run EtreCheck http://www.etresoft.com/etrecheck and post its result here. Hopefully it'll shad some light on your issue.

  • Pop up windows on mac book pro running slow

    OMG!!!! I have pop up windows everywere!!! my computer is running very very slow!!! SOMEONE PLEASE HELP!!!!!

    What kind of popups?
    If it's some kind of spam and they keep regenerating after you X out, you can always try using Command Q - which quits out the program (in this case your browser) all together.

    My Mac Book Pro has slowed to less than a crawl (possibly from a worm or virus).  How do I make sure it's running at peak efficiency before I complain to comcast

    Please answer as many of the following questions as you can. You may already have answered some of them; in that case, there's no need to repeat the answers.
    Restart the router and the broadband device, if they're separate. Any change?
    Run Software Update and install all available updates for OS X or the computer's firmware. Any change?
    If possible, connect to the router with an Ethernet cable and turn off Wi-Fi. Any difference?
    Are any other devices on the network, and if so, are they the same?
    If you can connect to more than one network, are they all the same?
    Are all network applications affected, or only some? If only some, which ones?
    Is networking always the same, or is the problem intermittent?
    Disconnect all other devices from the network. Any change?
    If you're running a MacBook with the lid closed, open the lid. Any difference?
    Start up in safe mode and test. Any difference?
    Start up in Recovery mode. From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Any difference?
    If possible, turn off Bluetooth and disconnect any USB 3 devices. Any difference?

    This diagnostic procedure will query the system log for messages that may indicate a hardware fault. It changes nothing, and therefore will not, in itself, solve your problem.
    If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.

    syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|nspace-h|n Cause: -' | tail | open -ef
    Copy the selected text to the Clipboard (command-C).
    Launch the Terminal 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 Terminal in the icon grid.
    Paste into the Terminal window (command-V).
    The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
    A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
    Step 2
    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 a portable computer, check the cycle count of the battery. It may be due for replacement.
    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. See whether there's any change.
    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.
    If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
    Step 3
    When you notice the problem, 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 4
    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.

    I have a mac book pro running Lion 10.7.4 and every time I use Google Earth The computer crashes by lowering a black curtain and then asking me to hold the power button down until it closes and press the power button again to restart it. Can I fix this? It bugs me when I'm looking at real estate.

    I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
    When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.
