ICal starts and runs really slow

I have a prblem with iCal working really slow. It takes almost a minute to start up and every added or modified event just ... mrrr ... it is so slow. What can I do ? I have the latest version of iCal on brand new Powerbook 12" on macOS X 10.4.3

This appears to be a general problem likely related to the change in the way Tiger handles iCal files. Because of Spotlight, each item has to be an individual file in order to be searchable. I think this puts a huge burden on iCal for those of us with lots of calendar items.
If you create a new user and then create an iCal calendar, is it still slow? It is not for me, which means it has something to do with my main user account, which has events going back to 1996.
Here is a thread with some fixes (delete preferences, reimport data, etc), but none seem to work for me. Your mileage may vary.

How large is your HD AND how much space do you have left? When was the last time you repaired permissions and restarted your computer? Boot up from your install DVD and run "Repair Disk" from the Utility menu. When done, restart back to your desktop, repair permissions and restart your computer.

My 2011 13'' MacBook Pro has started to run really slow.

I have a 2011 13" MacBook pro and this week it has started to run really slow. Specifically it takes about 3 to 4X longer to do just about every task. The only thing ive done recently was update from Lion 10.7.3 to 10.7.4 and a Safari update. Are there any suggestions on what I should do to fix it or on what could be the potential cause?

Things That Can Keep Your Computer From Slowing Down
If your computer seems to be running slower here are some things you can do:
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is 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.
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.
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.
Additional Hints
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.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.
If nothing here seems to help, then reinstall Lion:
Reinstalling Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

OSX.3.9 crashing like windows and running really slow, pleae advise

My power book G4 has been getting slower over the last few months, and really bad the last 2-3 weeks. I've cleaned off the hard drive (it says I have 4 gig free, but I should have about 10-15 gig free). I've run disk utility, mac sweeper, and tried onyx, run iClean, and nothing has changed. It crashes with the "mac screen of death" (the down fade with multilingual hold down the power button until restart instructions). It crashes about every day now, sometimes 2-3 times. The cursor turns into the spinwheel way too often.
Could someone reccomend a program or procedure to fix this apart from a reformat?
TIA

My MacBook is almost two years old and has started running really slow. It gets bogged down when it is running different programs at the same time, like Safari and Pages. It didn't react this way until recently. Any advice would be very welcome.

My MacBook is almost two years old and has started running really slow. It gets bogged down when it is running different programs at the same time, like Safari and Pages. It didn't react this way until recently. Any advice would be very welcome.

Launch Disk Utility and select the icon of the internal drive (the drive itself, not the volume icons below it.) Is the SMART status "Verified?" If not, replace the drive immediately. If the status is "Verified," the drive may still be failing. Back up all data, if you haven't already done so. Reinstall Mac OS X, then run Software Update. Test with all wired peripherals disconnected. If it's still slow, you have a hardware problem.

My Macbook Pro is running really slow and programs keep crashing

I have a 15" MacBook Pro (Mid 2010 Model) that is doing my head in, as it runs really slow most of the times as soon as I open more than one program (especially if I use Excel or Word of course). I ran the EtreCheck and the result is below, hopefully this will help some of you guide me in the right direction?
Most of my memory (over 200GB) is used up by "OTHER", any idea what that could be and how I could easily free up space?
Thanks a lot

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 and start typing the name.
Step 1
For this step, 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.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the name of the crashed application or process. For example, if Safari crashed, you would enter "Safari" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. 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.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.
When you post the log extract or the crash report, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

My MacBook Air just started running really slow

I have a MacBook Air and Safari started running really slow and I'm not sure why. I'm not very tech savy, so I'm having a hard time figuring out what's going on.

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?
Select the Advanced tab in the Preferences window and uncheck the box marked
Stop plug-ins to save power
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 Parental Controls is active for any user, please turn it off 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?

I believe my macbook pro hard drive is bad. I erased the drive and reinstalled the OS and the macbook still runs really slow. I dont know if the hard drive is the issue.

Did you try an SMC reset too? It's easily done and none of those resets to the best of my knowledge hurt anything. When I was fooling with my system, which at one point was a home made Fusion setup, I needed to reset the SMC sometimes to get the drives recognized. Reading the documentation the sudden motion sensor is drive related but that seems to be about it.
Some more specifics may be needed about the drive itself, the model number of your unit, and the OS version you're running.
At present, the problem seems sort of odd to me. FWIW cable problems can be quite intermittent. I used Scannerz to find some of the problems on my original system that I later converted to a new HD and SSD combo. It can find lots of problems if you learn how to use it right (HD problems, logic board system faults, and cable problems) but you need to get a system at least partially up and running to use it, and it doesn't sound to me like your there right now (in other words, don't go out and buy it because at this point I don't know how it could help you)
Another word of advice would be to not go out and start throwing parts at a problem unless you have a good idea what the source of the problem is. If you have a logic board problem, new drives and new cables won't make it go away, you'll just be wasting your money. Logic board problems, cable problems, and drive problems can all have very similar end user symptoms. The article that I linked above named "Hard Drive Problems" has a section on general symptoms of problems and if you read the article it becomes clear there's a lot of overlap associated with different types of problems.
I assume that your unit isn't under warranty. If, by chance it is I wouldn't even fool with it and I'd take it to Apple and let them deal with the problem. You also might want to check with whatever Apple sources you have available to test your system, like an Apple store, and see how much they'll charge (if anything) to evaluate the system.
I certainly hope this helps.

Photoshop Elements 12 runs really slow and is almost unusable.

Photoshop (and Premiere) Elements 12 runs really slow and is almost unusable.
All other high end software works perfectly including 3D rendering software.
27" iMac mid 2011.
16gb of RAM.
Over 100gb free hdd space.
Radeon HD card 2GB.
3.4 GHz Intel Core i7.
I have tested on tiny low quality images as well.
I bought this with the bundled Premiere Elements which is also unusable even with the smallest and lowest quality video file.
iMovie works fine as does other video editing software. I ONLY have an issue with Photoshop and Premiere Elements 12.
Mavericks 10.9.3
Elements 12.1

After the latest update, Firefox is much better. Using it again.

Can someone please help. I have a really old MacBook that is running really slow. I want to wipe everything and reinstall the latest software but don't know how to do this. Also is there a way of keeping Microsoft Office when doing this? Thanks in advance

You do realise that wiping the disk means that everything on the disk is erased. Everything. Photos, music, emails, ...
So the first piece of advice is to make sure you have a back up of everything.
You need the OS disk to reintsall the operating system. You will use that disk first to erase the drive, then to reinstall the OS.
Here's the link for the US. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
As for MS Office, you will need the original disk that it came on to reinstall it.

My iPad is running really slow, and I can't connect to my iTunes account or App Store ,keeps saying can't connect to server ,but have another iPad in house and it's working fine

My ipad is running really slow, and it will not let me connect to iTunes or App Store, but have another iPad in house which is working fine I,please help

Try a hard reset by pressing the Home button and Wake / Sleep button at the same time, keep them both pressed until the Apple Logo appears on the screen.
This does not lose any data on your iPad.

How large is your hard drive and how much hard drive space do you have left?
It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions.

I have iMac and need a good photo editing program to use. Reviews say aperture runs really slow with Lion, any suggestions?

I need a program where I can remove objects and touch up dead grass, etc.

Reviews say Aperture runs really slow with Lion, any suggestions?
To add on to Corky02 answer:
The recent Aperture release AP 3.3.x is very efficient, both on Lion and Mountain Lion. But you need a decent hardware to support it. The older Macs will have problems with the storage and CPU requirements. For good performance on large raw images plenty of RAM is important, at least 4GB, but 8GB would be much better, and your library should be on a fast disk, preferably on an internal drive. And don't let the system drive get too full.
Many reports about Aperture being slow are due to putting the Aperture library onto slow disks or acessing the original image files over the network, insufficient RAM, or corrupted or ill-designedAperture databases.
Aperture excels at all kinds of image processing that can be considered image developement - raw processing and color/lighting adjustments, but does not do compositing. If you are shooting raw and want professional image developement I'd recommend to do this in Aperture and not in iPhoto - you will have much more control over this in Aperture (after a steep learning curve). You can also repair and retouch the image to correct minor blamishes. For graphics compositing and inpainting you can set up an external editor and send your images from Aperture to this external editor - any of the editors Corky recommended would be o.k. for this.
To see, if you will want the advanced image processing in Aperture or the easy to use, more basic options in iPhoro will be sufficient to you have a look at the Aperture User manual, or the tutorial on the support page: Aperture Support
But Aperture is a professional apllication, not "plug and play". You should only consider it, if you are willing to spend some time on learning to use it properly and are willing to work your way through the manual.

Hey i have a old powerbook G4 laptop and i was wondering where can i download the OS ( Mac OSX 10.5.8 Build ( 9L30 ) to do a fresh install my system is running really slow is there any place where i can down load this OS?

Hello,
Unfortunately Apple do not offer a download for mac OS X 10.5.8. They will only provide updates available for download. ( Normally you would do so once the OS is installed)
To do a fresh install of this software your going to need to buy a retail copy of the disk.
There are some vendors who do still stock the media disk, but they can be expensive.
Best of luck.

ICal starts and runs really slow
