Why has my Imac recently slowed down

It has gotten very slow lately

How full is your hard drive?
Hhave you emptied OS X Trash icon in the Dock, lately?
Apple Mail and iPhoto have their own separate Trash to empty.
Have you emptied these?
Iin OS X Disk Utility, run the repair Disk Permissions routine.
If doing these things only marginally helps, next is to upgrade your RAM memory.
Newer Intel versions of OS X use a lot more CPU, GPU, hard drive and RAM resources.
The 4 GBs of RAM in your iMac is really the working minimum of RAM needed just to run OS X, alone, by itself.
Start running additonal applications and your iMac is going to slow down.
Your iMac can take a max. amount of 32 GBs of RAM.
Install, at least, another 4 GBs of RAM. Install more if you can afford it.
Here are the exact specs for the RAM your iMac needs
32 GB (Actual) 16 GB (Apple)
Memory Slots
4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM
Purchase reliable Mac RAM from online Mac RAM vendors Crucial memory or OWC (macsales).

Why has my internet connection slowed down?

Hi
I've recently experienced a connection slowdown for both Entourage and Safari. This reminds me of the old dial-up days. My Netgear statistics are - Download: speed 7616kbps, attenuation 22dB, noise 4dB; Upload: 448 / 6.5 / 23. I think these look quite healthy.
Recent changes have been auto Mac OS updates, installation of iMovie HD 6 and updates to 6.03, install iPhoto 6, updated to 6.06 and update to iTunes 7.
The only other changes have been the update of the Netgear (DG834G v2) firmware v3-01-08, and the installation of a network printer, Samsung ML-3051N.
I've had BT check the line for me, but nothing was found.
I've also tried repairing disk permissions, but this made no difference.
Can anyone please help me restore the speed I used to get, or are there any know issues with any of the above software updates?
Many thanks,

Since you installed system updates and software updates, run "Repair Disk Permissions" in Disk Utility, if you have not done so recently (after the installations).
In terms of the System Preferences Network pane, select Show *Network Port Configurations*. On the list of network services, make sure +Built-in Ethernet+ is at the top of the list. You can also uncheck services you are not using for networking, just in case there is a bug causing conflict.

My iMac Mid 2010 Has Suddenly Started To Slow Down.

Hello,
My iMac has suddenly started to slow down. It was fine just a week ago.. Login time has increased, Applications take a while to start and they can sometimes make my computer unresponsive.
Finder freezes and so does safari.
I have deleted ALOT of old files and things i don't use anymore. I deleted my Windows Partition. I have also tried my options in disk utility but it seems to have not no effect. I also re-installed Mavericks.
I don't know what else to try. Please let me know if there is anything i haven't tried.

Why has my iMac started to be slow logging on

Why has my iMac started to be slow when first logging on, is it anything to do with me upgrading to Mavericks from 10.7, and is there any way it can be rectified?

Launch the Console 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 Console in the icon grid.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.

My Macbook Pro is 18months old and has recently slowed down. specifically it wont load photos on Autotrader any suggestions?

My MacBook Pro is 18 months old and has just started to slow down. It is also not loadng certain photos from the autotrader website if this is relevant?

You may be able to improve the speed with some software work but it could also be your disk or SSD is corrupt or failing.
Try an SMC Reset:
http://support.apple.com/kb/HT3964
Is it faster now? If not, proceed.
Backup your data immediately:
Before proceeding you should make sure you have a current backup. If it has been getting slower over time your disk could be a failing slowly. SATA drives have two retry modes: short and long. They can continue operating as read errors are increasing. The long retry cycle is very long and can cause significant performance degradation. If it has started long retries then it is likely to get worse and eventually fail. SSDs also have a failure mode where the fail slowly.

and
Mac Performance Guide: http://www.thesafemac.com/mpg/
Safe Mode:
- Reboot the system in Safe Boot mode.
- Power on the Mac and when you hear the bong, hold down the shift key until it is booted.
- Be patient, this will take some time while it checks the filesystem.
If it runs faster in Safe Boot mode then it is probably third-party software compatibility issues.
- Restart.
- Does it run faster after the restart?
Spotlight: If Spotlight is continually running, re-index Spotlight:
http://support.apple.com/kb/ht2409
Runaway processes:
Launch Activity Monitor (in the Applications/Utilities folder).
Click on the CPU heading.
Are there a process taking up a large percentage of the time?
If so select it and click on the upper left hand X to force quit the process.
Run Disk Utility (found in the Applications folder):
-In Disk Utility look at the S.M.A.R.T. Status.
If it says the disk has a hardware problem that can't be repaired then stop.
Your system could be in danger of failing at any time and you need to replace the disk soon.
Back your system up twice.
(You will need a second external disk for the second backup.)
Consider using Carbon Copy Cloner or Super Duper! for the second backup to clone the disk.
Jump to the Hardware replacement section and seek expert help.
Repair Disk Permissions and Verify Disk. If Disk Permissions reports errors, don’t worry. That is normal. If Verify Disk reports errors then they need to be repaired. Otherwise skip to the reinstall OS X section.
Repairing your system disk:
- Boot in recovery mode.
(Boot and when you hear the bong hold down the
Command and R keys simultaneously until you see the recovery screen.)
- Select disk utility.
- Select your system drive.
- Repair Disk.
- Did it complete without errors?
If not you may need a new disk or SSD. Seek expert help.
If it completed normally then reboot.
-Did it boot faster and is it more responsive?
Reinstall OS X:
If it is still slow you should reinstall OS X.
- Boot in Recovery Mode again.
- Follow the instructions to reinstall OS X.
- Now does it boot and run faster?
Hardware replacement or upgrade?
Hopefully by now your Mac is back to its normal speed. If a hardware repair is indicated take it to an Genius bar at an Apple store for a free diagnosis and estimate of repairs. If it is under warranty or AppleCare they will repair it for free. If not, you can compare their estimate with DIY repairs.
Genius reservation http://www.apple.com/retail/geniusbar/ .
or find an Apple Authorized Service Provider https://locate.apple.com/country
You can speed it up further by upgrading some hardware. For the following memory, disk or SSD replacements and upgrades check out OWC http://eshop.macsales.com/, Crucial: http://www.crucial.com/ and Kingston http://www.kingston.com/us/. You will need to know your Mac the year and season your Mac was first sold and model number which can be found here:
 > About This Mac > More Info… > System Report > Model Identifier:
If your Mac has 2 or 4 GB of RAM, consider an upgrade to 8 GB (if the memory is upgradeable). An 8 GB memory upgrade is only $100. When I upgraded a MacBook from 2 GB o 8 GB it booted thee times faster.
If your Mac has a disk and it won’t repair properly, is low on disk space, or you just want a considerably faster disk, check out an upgrade to an SSD-Hybrid disk. Google "Seagate 1TB Solid State Hybrid Drive SATA 6Gbps 64MB Cache 2.5-Inch" or consider an SSD (120 to 480 GB).
OWC has SSD replacements and upgrades for MacBook Airs and Retina MacBook Pros.
Good luck. May the software fixes do the trick.

My iMac is slowing down

My iMac is slowing down and it takes a long time to start any application. What can I do to gain more speed?

What year, screen size, CPU speed and amount of RAM installed?
How full is your Mac's hard drive?
How many applications do you run simultaneously in the background while working in another application?
Do you run any antivirus software on your Mac? Antivirus software can slow down the normal operation of OS X.
Do you run any "crapware" like Mackeeper or any other type of "crapware" like so called hard drive "cleaning" apps?
Do a search for and download and install OmniDisk Sweeper and OnyX.
Here are some of my tips for deleting or archiving data off of your internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Other things you can do to gain space.
Delete any old or no longer needed emails and/or archive older emails you want to save to disc, Flash drive/s or to ext. hard drive.
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, Flash drive or ext. hard drive and/or delete any old documents you no longer use or immediately need.
Uninstall apps that you no longer use. If the app has a dedicated uninstaller, use it to completely uninstall the app. If the app has no uninstaller, then just drag it to the OS X Trash icon and empty the Trash.
Also, if you save old downloaded .dmg application installer files, you can either archive and delete these or just delete the ones you think you'll never install, again.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its thing initially, then go to the cleaning and maintenance tabs and run all of the processes in the tabs. Let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
If you have any other large folders of personal data or projects, these should be thinned out, moved, also, to the external hard drive and then either archived to disc, Flash drive or ext. hard drive and/or deleted off your internal hard drive.
Good Luck!

Why has my iMac quit showing videos?

why has my iMac quit showing videos?

Thank you for the idea but I have downloaded Flash three times within the last hour and still no video. I have tried youtube, FoxNews, and CNN news.
Could I have some settings wrong? If so whitch settings?

Why has my iMac screen gone to stripes. I am using Yosomite

why has my iMac screen gone to stripes and nothing else. I am using Yosemite

Could be the card or the screen.
Courtesy BDAqua:
Take a screen shot & view that in Preview, move the Preview window around, if you see double lines it's a Video card/VRAM problem, if the lines do not move moving the pic around then it's the LCD or cable.
If your screenshot isn't showing the stripes here, it will most likely mean the screen, LCD panel, is the problem.

IMac 700 slowing down

My wife has noticed her iMac 700 with OS X 10.4.12 really slowing down considerably after the upgrade to .12 several weeks ago. The hard drive shows only 12+Gb remaining out of 40GB, 25+ used. I have gone through and cleaned all the caches and recent items files with no change and she keeps clearing the Safari Cache regularly, almost daily recently. I have also folderized all documents on the desktop and removed all document no longer in use. The last update is probably the last "Optimize".
Is there anything else I can do to bring this back to some kind of regularity?
Sparkgapper

Then I guess my question is answered even though I have no time to first find one of those forums and secondly it would not then be worth the hassle and trouble it would cause by "do this" if that doesn't work then "do that" or "there is no way to do that on an iMac" when I am quite sure the primary problem is defrag (called Optimization by apple) since there has not been an systems upgrade in quite some time.

My iMac (2009) slows down after I go to sites that are memory intensive

I have noticed my computer slows down to a crawl after I use sites that I believe are memory intensive. Example of that is iFirstrowSports.eu (streams soccer games live). The latest one was Wix where my wife was building her web site using their html5 tools.
I have also noticed that when the system is running slow, not all websites run as slow as others. Fro example abola.pt is very slow, while yahoo.com or yahoo mail will be slow but not horrible. I am wondering if it has to do with how those sites use memory or the technology they leverage.
I went to EtrCheck and run a report. Note that this report was done when the system is performing well.
I would appreciate some help and advice.
Thanks
Problem description:
machine slows down when I go to sites that use video (ifirstrowsports.eu as an example) or memory (wix site creation tools)

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, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Why does my AI acquisition slow down to my frequency measurement rate?

I'm using Labview/Daqmx to program my SCXI 1520 and TC modules while at the same time using the multifunction capabilities of the E-card controlling the SCXI. This has been fairly easy until I wanted to use the frequency and counter measurements (outputs/DIO works great). I'm using a waveform with buffered acquisition for the read on the AI channels and obviously there is no waveform for the frequency measurement so I'm just combining the signals using the dynamic data. This works great when my input frequency is higher than my acquisition frequency. When my input frequency is lower than my acquisition frequency the acquisition slows down to that frequency and the AI read falls behind (buffer fills while waiting for another frequency measurement). I'm assuming the frequency read is not keeping up with AI read. I understand that as the frequency is reduced it takes more time to calculate the frequency. So how do I "read" the frequency measurement at the same rate as the AI data? I'm fine with using the last frequency measurement until a new frequency measurement is available but I can't even seem to be able to do that.
An example of the problem is measurement of vehicle pedal force (AI channel) with pulse input for vehicle speed. Assuming 100 Hz acquisition and the vehicle stopped or going slow (very slow pulse train) I should be able to acquire data at 100 Hz even if I just use the last data point for the frequency channel until another point is available.
Please help, thanks.

Basically, the very fact that you're *doing* a frequency read suggests that you don't know the expected freq ahead of time, and probably suggests that it can vary. The waveform datatype assumes a constant interval between samples which wouldn't generally be true for frequency measurement, and that's why you can't use it. Since the actual timestamps of the frequency measurements are NOT the same as those in the analog waveform, it's likely a mistake to pretend they are.
My method is to create my own array of "timestamps" for the frequency data. Create a For loop with a shift register initialized to 0 from outside the loop. Let your freq array auto-index the loop. On each element, perform (1/x). Add result to the left-hand shift register value and write it to both the right-hand shift register and to an auto-indexing output. When the loop completes, the output array will hold timestamps that correlate to your freq measurements. From there you can choose whether to display on an X-Y Graph, or whether to perform some interpolations to calculate freqs at the analog sample times or vice versa.

Why does my iMac not shut down when I try to shut it down?

Wh does my iMac not shut down, or restart when I try to do either. It just sits there with the little loading circle continuously moving. The only way I can shut it down is if I hold down the power button to shut it down. Can anyone tell me why this is?
Thanks!

Open your Activity Monitor and check to see what is running?
If there is some important Process running, then it is better to wait until it has finished instead of cutting the power and corrupting who knows what?
If there is nothing important running, then follow the instructions in the link below for resetting the SMC.

WHY is my iMac so slow now? Especially Safari?

Hey
Please please someone help me, i have had my iMac now for two and a half years and its always been fine. Its got 4gb ram and 500gb hard drive.
All of a sudden it just started to slow down, so much that everything freezes.
Safari is so slow especially when trying to playing YouTube videos, when i try and play them the whole machine just freezes!
I updated it to Lion and also took it into my local apple repair shop and they couldnt find anything wrong with it at all!
I transfered like 200gb of data onto an external, that didnt help, repaired permissions and that didnt help. I reset Safari and that didnt help.
Its got so bad that even when i search for something on my Mac e.g. if i type in INVOICE into spotlight search it takes abot 30 seconds to show me anything!
Please someone help, its mainly laggy on Safari 5.1.7 but the whole machine is effected by it!
Please help!

Linc Davis: I have a similar problem and followed your instructions, probably something to do with the Google Chrome issue but I don't know what it means, duh...this is my console text:
