Why does my macbook run so slow?? I am running OSX 10.8.4

I am running OSX 10.8.4
My Macbook pro is running extremely slow.
It takes a while to power down.
web pages do not pop up automatically like in the beginning.
What can i do to get my laptop back to fresh out the box performance???
This is getting irritating, since i need this laptop for school.

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.

Why does my macbook run slow?

Browsers, iphoto load very slowly. I have to do a lot of force quitting. I empty cache, and have only a dozen or so, mostly alias items on my desktop, but my machine is behaving like the pc it once replaced.
Is there a repair software recommended? Or should i take to a dealer for service. Thanks for any help. The following is my info:

When openning mail or Sarfari or almost any application it takes for ever to load; Send something to printer and it locks up for 5 minute then finally send to printer; over all performation is very slow?

What is application memory and why does my macbook pro keep running out of it?

what is application memory and why does my macbook pro keep running out of it?

There is excessive swapping of data between physical memory (that is, the memory chips on the logic board) and virtual memory (one or more files on the startup volume.) That activity is relatively slow and causes the whole system to be less responsive. It can happen for two reasons:
          A long-running process with a memory leak (a kind of bug)
          Not enough memory for your usage pattern
Please note that if the cause is a memory leak, installing more memory will not help. That's likely if you already have more than 4 GB of memory. Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
These instructions are for OS X 10.9 and later. Some details may be slightly different for earlier versions of OS X.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the View menu, if it's not already selected. Select the Memory tab. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
          View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The processes named "Safari Web Content" render web pages for Safari. They use a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider them prime suspects.
Another process often implicated in memory leaks is "inkjet4" or "inkjet8," which is a component of the HP printing software. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. Empty the print queues in the Printers & Scanners preference pane (which has a slightly different name in each recent version of OS X.) If you don't use an HP printer, reset the printing system. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
"Wired" memory should be a small part of the total. That memory is not swapped, but it makes less physical memory available which may then result in swapping. If you have a lot of wired memory, that's usually an indication of a memory leak in a third-party program that modifies the operating system at a low level. Ask for guidance in that case.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

Why does the MacBook Retina 15" do software scaling to the native resolution of 2880x1800?

OS X does not allow changing the viewport resolution to the native 2880x1800, and it suggests 1440x900 as a retina optimized one. This means that software scaling is done on the fly. My question is, why?
I have two suspicions:
1. Running everything at the native resolution puts a bigger strain on the GPU, hence slowing down the OS, putting down battery time.
2. The number of apps using retina-ready sprites is miniscule, hence Apple does not want to mess with the user experience. Although I doubt it, as software post-processing is done even now, and apps with non-retina sprites look slightly blurred. If the native resolution would have been used, they would just look a bit more blurry.
Just some comments:
1. Switching to the native resolution will make everything smaller, up to the point of not being usable. But this is a non-argument, as the OS could be smart enough to use bigger versions of the sprites/icons/text. Apple already demands that developers use hi-res sprites (OS X Human Interface Guidelines), hence everything could be scaled x2 and it would be the same size at 2880x1800, as it is at 1440x900 in the current version of the OS.
2. Technically it is possible, as outlined here: Running the Retina MacBook Pro at Full 2880x1800 Resolution. Have a look at the comments too, there are some interesting observations in line with this question, but no definite answers.
3. I am aware that the OS X Cocoa server is running at native resolution at all times. This question is concerned with the viewport resolution, which requires hacks to be set to the native one.
Can answer on Quora if preferred (http://www.quora.com/OS-X/Why-does-the-MacBook-Retina-15-do-software-scaling-to- the-native-resolution-of-2880x1800)

Why does my macbook pro retina display shutdown while entering the administer account

why does my macbook pro retina display shutdown while entering the administer account

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 the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
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. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. 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.

Why does my MacBook Pro and Mac Pro keep freezing?

Why does my MacBook Pro freeze?
MacBook Pro
2.4 GHz intel Core2 Duo
4BB 1067 MHz DDR3
OSX 10.6.8 Snow Leopard
I turned it on and I went to safari to look things up. Safari froze and then the whole thing became unresponsive - the mouse could move the cursor but it couldn't open any programmes.
Tried safe boot several times. No help.
Tried to repair disc permissions. The first time it got a little way then said 'user stopped repair' or something - though I didn't touch it. Tried again it got all the way through and said 'repairs complete'. But no help.
Couldn't clear cache etc as couldn't get to the relevant part to do it.
Opened in single user mode. Ran the fsck -fy thing twice. First time it said both “The volume appears to be OK” AND “FILE SYSTEM WAS MODIFIED.” In 2nd run it just said “The volume appears to be OK”. No help.
Booted it up from the Superduper bootable backup version on a USB external drive. It seemed to boot up ok but then tried to click on something and the same thing happened - spinning beach ball and it just hung.
Erased hard drive and reinstalled snow leopard but it just does the same thing. Suggesting a hardware issue not software but...the Eerie thing is, we tried backup version on boyfriends Mac Pro and it worked fine on there but 24hrs later his Mac Pro has got exactly the same screen freezing, unresponsive issue. Could this suggest there's something evil lurking on my back up? Can't get an appointment at Genius Bar until next week and need to get some work done, so hoping someone might have some ideas?
Cheers

... does Apple products work much better with using Apple routers?
While a genuine Apple router is likely to result in success, the reason for having one instead of another product is that it eliminates a lot of uncertainty. For example, we do not know the model D-Link product you have so no one is in position to speculate what the problem might be. Also, it makes support on this forum easier since there are only three AirPort models to choose from and they all work more or less the same.
Generally speaking your iPods, iPads, MacBooks, and AppleTV ought to work with any router though, provided it is fairly recent and meets accepted industry standards. If in doubt you can purchase an AirPort Base Station, which comes with 90 days of free telephone support. If it does not result in any improvement for you, you can always return it for a complete refund. The return period is 14 days and be sure to keep all material - receipt, box, manuals, etc...
If you elect this option be sure to follow its installation instructions, the most important of which is to power down your modem prior to connecting the AirPort Extreme, Express, or Time Capsule. All your other equipment will need their network settings adjusted to "forget" the D-Link network and connect to the new one.

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.

Why does my macbook pro stop loading the webpage every time i try to access netflix or youtube?

Why does my macbook pro stop loading the webpage (in safari) every time I try to access netflix or youtube?

Back up all data before proceeding.
This procedure will unlock all your user files (not system files) and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes on any of your files, 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.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Triple-click anywhere in the following line on this page to select it:
sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) 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:
res
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.

Why does my MacBook Pro make background music and video quieter when I am on FaceTime?

Why does my MacBook Pro make background music and video quieter when I am on FaceTime? When my girlfriend and I are trying to watch a movie on Netflix together while on FaceTime my MacBook Pro always decreases the volume of any background sound on my computer so I can barely hear it. Is there a way to fix this? Thank you!

Have the same issue too. Apple can you please change this annoying feature. You are making long distance relationships more difficult.
I like how Facetime was with the old iOS, where nothing was dimmed. OR at least maybe if you could give users the option to turn on or off dimming of facetime.

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
