My macbook seems to be slowing down....any thoughts on how to speed it back up?

2 years old and slowing down.....

Free:
- Use disk utilities (Applications -> Utilities -> Disk Utilities) to repair the permissions.
- Also, allowing your computer to shut down and start up again will help as Mac OS X runs various scripts to clean and do some light optimization stuff.
Software wise:
- Defragmentation programs will work also. Other (some free, some paid) programs are available that will perform various actions to speed up your computer.
Hardware wise:
- add RAM, max out.
- Hard drive: upgrade to 7200 rpm or an SSD drive or Seagate's Momentus hybrid SSD/standard platter hard drive.

    How much free disk space do you have?
    You may want to run these "standard" fixes if the problem persists.
    1) Check the amount of free space on your harddrive.  You should have a several gigs free.
    2) You should run disk utility
         a) verify the disk
         b) update your permissions.
    3) Try a safe boot.
        Shutdown your machine.  Hold down the shift key.  Poweron.  Wait awhile Wait awhile while you harddrive
          is being checked.

    Look at what is happening with your Mac when you run Activity Monitor.
    Macintosh-HD -> Applications -> Utilities -> Activity Monitor
    1) Be sure you select all processes in the double arrow selection just be low the window title line.
    2) Click on the CPU tab on the lower half of the window to see how much time you are using and if any applications are hogging the CPU.
    3) Be sure the triangle in the CPU title is in the down position.  This will list the processes from high to low.
    You can gain some understanding of Activity Monitor by  looking at it every once in a while.  Look at the small graph.
    Here is how I have my CPU display set up:
    Do you need more cpu memory.
    Click on System Memory to get statistics on memory usage.  You should have some free memory.
    The number to look at is page outs.
    Mine is 13397. This means that some of my programs and data had to be written to disk because cpu memory filled up for a time.  It means my programs ran a little slower than they could have.  I could run fewer programs, deal with the slowness, or buy more memory. I'd say you want at least 512meg of memory for 10.4.
    If the entry for entry for Page ins/outs is:
    Page ins/outs: 29163/0
    Notice I have 0 pageouts which says that I am not using my harddrive for extra memory space.  Thus, I have enough memory.
    Activity Monitor has a neat feature where it can display a dynamic dock icon.  In Activity Monitor View > Dock icon > Show cpu history.

    4mccarthys,
    If you are certain that iCal is no longer present on your computer...
    To reinstall iCal:
    1. Insert the Leopard Installation disk into the computer.
    2. The disk will appear on the desktop.
    3. Double click on the "Optional Installs" folder.
    4. Double click on the "Optional Installs.mpkg."
    5. Click on (Continue) in Introduction.
    6. Click on (Continue) in Software License Agreement.
    7. Click on (Agree) to agree to the terms of the software license agreement.
    8. Click on the disclosure arrow ▶ next to Applications.
    9. Select (✓) iCal.
    10. Click (Continue).
    11. After iCal has been reinstalled, download and install the Mac OS X 10.5.8 Combo Update to bring iCal up to the most recent version.

  • I have added (plug in's or add-on's) example, Weatherbug. I want to remove them. They seem to be slowing down my computer. How do I do this? do they slow down my computer? thanks, Gary W. Luster

    I have Firefox add on's such as Weather-bug and Reminder. I want to know if these add on's can slow down my computer. They seem to be doing that. And, if I need to delete these add-on's from my computer. How would I go about doing that?
    Thank You,
    Gary W. Luster

    Just to the right of your post, you should see an "Edit this post" link. Click that, and then next to the subject text just above the message text edit box, you should see an "edit" link. Use that to remove your email address.
    To remove an add-on, go to the Add-ons menu item. In Firefox 4 that's on the FireFox menu (upper left corner of the window). In older versions it's on the Tools menu. Then you want to choose the Extensions tab, and find the add-on you want to remove. It should have a Remove button next to it.

    I keep getting the spinning wheel, and macbook pro seems to be slowing down.  How do i fix this without buying software?

    Go to system profiler and report back the amount of RAM that you have.
    Make sure that you have at least 20% of your hard drive free.
    Make sure you don't have a lot of items on your desktop as that can slow things down.
    Quit applications that aren't responding or you aren't using and won't be using for a while.
    ~/Library/Caches Quit all applications and delete this folder. Do a regular delete then do a secure erase on all the items that won't delete.
    If it only happens with a certain application (Safari for example)...
    1. Quit the application (Safari)
    2. Open ~/Library/Preferences and find the file for safari (com.apple.Safari.plist).
    3. Put the file in the trash. Do NOT empty the trash yet. Open the application and make sure everything's ok. Now you can delete the file. In Mail if you trash the file, you will get rid or your setup.
    Make sure that your dashboard doesn't have too many widgets and use Activity Monitor to see what it's using.
         There are ways to disable if you want to.
    Make sure that all of your software is up to date.
    Repair permissions (it can't hurt)
    Don't have a lot of login items.
    Your internet browser shouldn't have a lot of extensions.
    I hope this helps

  • Finder/Graphics seem to have slowed down

    I've been having a problem (or possibly two) lately: If I'm running several programs, or one very intensive program like Mathematica, my Dock suddenly takes a long time to appear when I mouse to the edge, and/or clicking on a Finder window does not bring the window to the front, although I can move it around behind the other windows.
    I have 25 GB of disk space, but only 512 MB of RAM, and I can hear the drive going alot. But it seems to be slowing down graphics such as the Finder windows or browser loading drastically as well - I thought graphics were handled by a separate system?
    Is there anything other than increasing RAM that would alleviate this issue? It didn't happen before.
    Oh, and I've repaired permissions and such. Also, I just recently had to have the logic board replaced, because it stopped reading the computer's power supply status.
    Thanks for any suggestions you could give.

    Hi Jim,
    Maxing out the RAM will help quite a bit, when the OS needs more RAM it uses VM, or Disk Space, and Laptop drives aren't very fast either, so a faster bigger one would help, they sell 7200 RPM ones now with more cache also.
    25 GB might sound like a lot of free space, but let's say it's a 100 GB drive, then whenever the OS needs to use some for Virtual Memory, it basically has a one in four chance of finding it right away, and that will most likely be very fragmented, so the HD must jump back & forth thousands of times to write one file.
    At this point I think you should get Applejack...
    http://www.versiontracker.com/dyn/moreinfo/macosx/19596
    After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
    applejack AUTO
    Then let it do all 5 of it's things.
    At least it'll eliminate some questions if it doesn't fix it.
    The 5 things it does are...
    Correct any Disk problems.
    Repair Permissions.
    Clear out Cache Files.
    Repair/check several plist files.
    Dump the VM files for a fresh start.
    First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files, but you should see some speed improvement!

    I have a Macbook Pro that was slowing down. The HD was nearly full as I do a video work. I removed over 400gb of photos and video and it made no difference. I ran disk inventory x and that says that there is only 60gb on the hard drive but disk utility says there is still 430gb on the HD. How do I remove what DU says is still there.
    Thanks

    You may notice a difference in available space statistics between Disk Utility, Finder, and Get Info inspectors. This is expected and can be safely ignored. The Finder displays the available space on the disk without accounting for the local snapshots, because local snapshots will surrender their disk space if needed.

  • Why is my 15'' macbook pro Early 2011 slowing down in performance often?

    Why is my 15'' macbook pro Early 2011 slowing down in performance often? It's barely got anything in it and it lags alot of times. This is supposedly running on quad-core i7 2.2 yet I have to restart at times to make sure it gets better. Why is that so?
    I turn on activity monitor and there aren't even anything taking up power or memory. It just lags out of the blue.

    Activity Monitor may still offer a clue. By default, it shows only "My Processes," those related to your user account. To see the real picture, you need to set AM to show "All Processes" as in this view:
    Click the header "%CPU" to sort by usage. Most true resource hogs are only apparent in this view.

    Click on the blue Internet Recovery in nbar's post. That is a link to what computers can run Internet Recovery.
    Do a backup,  preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors.  Reformat the drive using Disk Utility/Erase Mac OS Extended (Journaled), then click the Option button and select GUID. Then re-install the OS.

    are locked user files or that have incorrect permission a bad thing?
    Yes.
    why am i removing symantec?
    Short answer: Because it's worse than useless and worse than the imaginary "viruses" you're afraid of would be if they really existed. For the long answer, see below.
    1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to log in to it remotely. That threat is in a different category, and there's no easy way to defend against it.
    The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.
    OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
    2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
    The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
    The following caveats apply to XProtect:
    ☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
    ☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
    As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
    3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
    Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
    ☞ It can easily be disabled or overridden by the user.
    ☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
    ☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
    Apple has so far failed to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. These failures don't involve App Store products, however.
    For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
    4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
    5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, and a technological fix is not going to solve it. Trusting software to protect you will only make you more vulnerable.
    The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the scam artists. If you're smarter than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
    Software from an untrustworthy source
    ☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
    ☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software.
    ☞ Rogue websites such as Softonic and CNET Download distribute free applications that have been packaged in a superfluous "installer."
    ☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
    Software that is plainly illegal or does something illegal
    ☞ High-priced commercial software such as Photoshop is "cracked" or "free."
    ☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission.
    Conditional or unsolicited offers from strangers
    ☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
    ☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
    ☞ You win a prize in a contest you never entered.
    ☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
    ☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
    ☞ Anything online that you would expect to pay for is "free."
    Unexpected events
    ☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
    ☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
    ☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
    ☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
    I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
    6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
    Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
    Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
    Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
    Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
    7. Never install any commercial "anti-virus" (AV) or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
    Why shouldn't you use commercial AV products?
    ☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
    ☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
    ☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
    ☞ Most importantly, a false sense of security is dangerous.
    8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
    An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
    Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
    London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
    You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in everyemail attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
    The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
    9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
    10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It's as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

    Kappy's Personal Suggestions for OS X Maintenance
    For disk repairs use Disk Utility.  For situations DU cannot handle the best third-party utilities are: 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. Drive Genius provides additional tools not found in Disk Warrior.  Versions 1.5.1 and later are 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. I also recommend booting into safe mode before doing system software updates.
    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):
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    SuperDuper!
    SyncTwoFolders
    Synk Pro
    Synk Standard
    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.
    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.

    Hello there, Capricious13.
    There are great pointers in the following Knowledge Base article. Depending on where you see the content and where you want to get it to, this should guide you to putting it in the right place:
    Downloading past purchases from the App Store, iBookstore, and iTunes Store
