Welcome to the Apple Discussions!
Let me refer you to an excellent website about maintaining Mac OS X. It also has great troubleshooting tips and ideas. The site is maintained by a regular contributor to the Apple Discussions, Dr. Smoke. The site is the X Lab.
Some of the things that you might try are Repairing Permissions from Apps/Utilities/Disk Utility. Resetting the PRAM. Also making sure that the Cron Scripts have actually been running on your Mac. The X Lab can instruct you in all of these ideas and more.

My Mac has gone really slow since upgrading to Mavericks. Any suggestions as to how to speed things up again?

My Mac has gone really slow since upgrading to Mavericks. Any suggestions as to how to speed things up again?

First, back up all data immediately unless you already have a current backup. If you can't back up, stop here. Do not take any of the steps below.
Step 1
This diagnostic procedure will query the log for messages that may indicate a system issue. 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.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail | awk '/:/{$4=""; print}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) 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.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Reset the System Management Controller.
Run Software Update. If there's a firmware update, install it.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
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.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
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 View menu or 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 Memory tab. What value is shown in the bottom part of the window for Swap used?
Next, select the Disk tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in andWrites 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 by pressing the key combinationcommand-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.

HT5429 Why has the maps app gone so sour in IOS6 can I revert to IOS5?

Why has the maps app gone so sour in IOS6.The images at any reasonable magnification are colourless and so fuzzy as to be useless.I loved my old Google based system which even allowed me to look into my house window from the street view function.I wish I had never accepted the invitation to upgrade to IOS6 I would like to go back tithe old system

Google and Apple have apparently parted ways in the 'bundled apps' area.
If you don't like the bundled map app, then your option is to look for a replacement in the app store.

Why has iTunes gone really slow

Ok for some reason after updating from one of the software updates for mountain lion, iTunes has now become really slow! It's extremely annoying because every time I open it up the whole mac becomes slow and lags loads! I was just wondering if anyone else is experiencing anything like this or is it just me? Also if you know what's wrong, please help me as I can't do anything whilst iTunes is syncing my iPhone and iPad. Thanks.

IMac operating really slow

Hi, I have a G5 iMac, which for the last couple of weeks has been operating really slow. I've tried re-starting it, re-setting my Airport, in case it is internet related but it still keeps operating slowly. I get the spinning beach ball while it is thinking and then finally it functions, only to happen again. Occasionally, I get normal operating speed but then it happens again. I'm just going through a software update to see if there's anything I've missed out but is there anyone who is having the same problem, and is there anything anyone can recommend?

Not sure if this is related, Brett, but Apple have just released a new KB page detailing a problem which can occur when using some 3rd party VPN software under OSX 10.4.8:
Issue or symptom
After updating to Mac OS X 10.4.8, if some third-party VPN client software is installed, Activity Monitor may show the AirPort process taking 90% or more of the CPU time, and the computer may seem "slow".
Products affected
Mac OS X 10.4.8
Airport
Solution
Make sure your third-party VPN client software is up-to-date. Contact your network administrator or the manufacturer of your VPN client software.
This document will be updated as more information becomes available.
(from http://docs.info.apple.com/article.html?artnum=304798 )
Not sure if this applies to you, but worth considering.
Regardless, you might want to start up Activity Monitor (in your utility folder), open the "Activity Monitor" window, and then choose "active processes" to see if this, or some other software, is hogging your processor.
Cheers
Rod

Why has my wireless internet suddenly become slow?

Over the past few weeks or so my wireless internet has become really slow, and i don't know why. I have a Linksys WRT54G. Im pretty sure its the router because i connect my laptop to my modem and the internet works better. Do i need an upgrade or something?

YES... try the upgrading the rtr first..or check your isp..they might be getting slow themselves..

Why is transferring music onto iphone really slow?

for a couple of updates now the moving of music onto ipods/iphones has been really slow, sometimes it adds to the device but remains blacked out on iTunes or sometimes it says complete but hasn't added to the device ?!
what happened to the simple drag and drop? iTunes got so fancy it no longer does the job it was meant to!!

It depends on where you download them from; I have plenty of jazz in Podcast.

Apple tv is really slow

Apple tv is now really slow. I went out and bought a new generation apple tv because the old one was not performing. New one is no better. I went through trouble shooting with my service provider and i am getting 50 mbs. Now I look at the the forum and I see this is a problem with apple. I think apple is to busy trying to split up Steve's inheritance and now the wheels are falling off the wagon.

Can't say I've noticed that. I certainly couldn't read my titles as I scroll through my lists at full scroll speed, I'd say it takes about 5 seconds to scroll through 200 items. How slow is it for you. I have noticed however if I go to a new menu, it won't begin to scroll the options for around a second, which actually seems like a long time.

Buffering Apple TV is really slow

The buffering between my Mac and Samaung TV using Aplle TV is really slow for videos and movies. It seems to have got gradually worse over the last few weeks and now Youtube videos will not all load!
Any ideas as I am feed up of wacthcing a 4 minute video over 4 hours while I wait? need to be simple though as I am a technophobe

IPhoto 9.1.5 on my imac and MBP has gone really slow when editing etc.

I have noticed that on both my machines iPhoto hangs continuosuly when edits are made to the picture such as denoise etc. It hangs when moving to the next picutre and sometimes I have to Force Quit. I have reinstalled iPhoto, repaired the photo library, tried logging into my mac on a different account, repaired disk permissions etc. The fault still occurs. I am using Leopard and hardly use my MBP apart from installing the regular software updates which I believe might be to blame.

The database is corrupted.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .
Regards
TD
