Why is my macbook air so slow?

why is my macbook air so slow?

First, back up all data immediately, as your boot drive might be failing.
Step 1
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.
Triple-click anywhere in the line below on this page to select it:
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 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.
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.

    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.
    Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
    If your browser is Safari, then from the Safari menu bar, select
    Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
    and confirm. Any change?
    Quit and relaunch the browser. Any change?
    Log out and log back in. Any change?
    Enable Private Browsing in the Safari menu. Any change?
    Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
    If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
    If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
    Again, if only Safari is involved, open the iCloud preference pane and uncheck the box marked Safari, if it's checked. Any change?
    Are there any other devices on the same network that can browse the Web, and are they affected?
    If you can test Safari on another network, is it the same there?
    If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

  • Why is my Macbook Air super slow?

    I just bought a 2012 13 inch Macbook Air about two weeks ago and I've been using it to finish an essay and various other assignments.
    The thing is, the computer seems to want to slow down and not work, especially when I'm doing a lot of things on a lot of different applications. Sometimes it will freeze and I will have to reboot it for it to cooperate again. Most of the time, it will just slow down and if I leave it be for like 10 minutes, it'll start working again. Other times it will freeze and not allow me to click, scroll or anything else. Both are fairly frequent occurances.
    Perhaps what I'm doing is too much to handle? I would really like to know if this is normal or if I need to get it fixed.
    Any advice is much appreciated!

    It's too bad you waited until after the two-week exchange period to do something. Take it to an authorized service facility for warranty service.

  • Mid 2011 Macbook Air Painfully slow.

    Mid 2011 Macbook Air Painfully slow.
    Hey everyone.  I am writing about my 13 inch Mid 2011 Macbook Air. 
    Recently it has been extremely slow and on occasion has not started up.
    I have reset the PRAM and SMC already, yet it is still very slow.  I have a couple theories about what might have caused it, are they plausible?
    Theory 1:  It’s a software problem. I tried to upgrade to 10.8.2 but halfway through the upgrade the computer restarted and somehow I was still on 10.8.1.  For fear of a big issue happening I didn’t try to upgrade again. Perhaps it is a flaw in Apple’s software update? 
    The important thing to note about this update is that I tried to install 10.8.2 around a month or two weeks BEFORE I started having problems.  So if these issues were due to 10.8.2’s failed update then it certainly was a delayed reaction. 
    I would of course like to update to 10.8.2 BUT as my computer is acting EXTREMELY slow and having trouble turning on occasionally I am worried the software update will completely brick the machine.  Is that possible?  Should I actually finish through with the software update?
    Theory 2:  It was an electricity problem. 
    The computer died when I was sitting at a café plugged into their wall sockets.  A few days later when I came back to the same spot with my old macbook which is now being used in lieu of the Air it suddenly turned black for a little while. Sensing it might be an electricity surge or something with their system I unplugged the cable.  I am not sure if that was paranoia though. 
    Can an electricity surge or a bad outlet fry a computer?  Can it fry the ram so the computer is extremely slow? Does that theory hold any water? 
    Thanks for your help diagnosing this problem.
    All the best. 

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    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. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Copy or drag — do not type — the line below into the Terminal window, then press return:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' 
    Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.) You can omit the final line ending in “$”. 
    Step 2 
    Repeat with this line:
    sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}' 
    This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3
    launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}' 
    Step 4
    ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null  
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 5
    osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null 
    Remember, steps 1-5 are all drag-and-drop or copy-and-paste, whichever you prefer — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

  • Why does my Macbook Air make a single buzz/beep?

    Why does my Macbook Air make a single buzz/beep every time I open it or turn it on? It doesn't happen after again after the initial buzz. If I open it after it has been sleeping, it starts up and then there is a buzz. This has only happened since I downloaded iOS Maverick.

    Beeps on startup:
    1 beep = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images.
    5 beeps = processor is not usable
