Really slow start up on my MBA

I read some posts, and tried most of the suggestions but still really slow.
I tried: cleaning computer and deleting files, also got rid of Bootcamp which I don't use Windows, ran MacKeeper, also removed all Login Items under accounts. It takes 1min 45 secs to get to the blue screen, and another minute to finally get all the icons in place.
Help.

Welcome to Apple Discussions!
Try cleaning up your Mac*:

And try repairing permissions and directory after a backup*:

Really Slow Start-Up, force shut-down, only with one user....

Lets see. I've had this puppy since August of 2005. We've been through a lot together. Im sure this is apple telling me to buy a new computer BUT all I want is to make sure I do not lose ANYTHING of importance. THE PROBLEM:
So, I used my computer on Saturday, came home late on Sunday to check my e-mail. And I turned it on, logged into my Administrator account and go distracted, 30 minutes later the desktop hadn't fully loaded. The background picture came out, the tool bar from the little apple to the Help loaded, but my google notifier, airport and time and finder did not load. The application bar at the bottom loaded, but nothing happened if i moved the mouse over it. I had maybe 10 files and 4 folders on the desktop, so i tried moving them. I logged into another account to delete stuff I didnt need. It got a little better. I was able to actually move the folders into the HD icon on the desktop, and TRIED to take the picture off the desktop, but I ended up having to go to bed after hours of trying to fix it.
I would have copied everything to disks, but a few months ago my CD/DVD ROM failed. Well, I never got it looked at because i've been in transition to LA. But it just spits any disk that is put in.
I thought maybe I have too much stuff on the HD, causing it to be slow, but its not even 1/2 full. So that really can't be it.
I have 2 accounts on my iBook. One is mine, the Administrator and the second is the Guest account for anyone borrowing my computer. I tried logging into the Guest account and it works perfectly. No problems with it at all. I am sooooo confused as to why overnight there is another problem with my computer. I have an appt with a Genius on Thursday, I do have my OSX Install Disks. I just found them!!
Any thoughts or suggestions GREATLY appreciated.

I've been trying to help another individual with an issue similar to yours. That case is a little less extreme--only certain applications cause trouble, not the whole works.
http://discussions.apple.com/thread.jspa?threadID=1862986
See if any of that helps you. If not, it's probably best to ask the Apple experts when you go see them--my final idea is to erase and install the OS, which isn't an option for you since the CD/DVD drive doesn't work.

Crashing Mac OS X and really slow start up

My Mac Book Pro with OS X 10.5.3 keeps rebooting. I get a screen that states that the computer has run into a problem and must reboot. When it reboots it takes a long time to start up. After loggin in it asks to send a report to Apple about it crashing. What can I do to prevent my computer from crashing. During the times it has crashed I have had at most the following programs open: Safari, Mail. So I am not doing strenuous computing.

Here is the most recent one. There are 2 crashes one on the 9/11 and 9/15 plus 2 other panics. Should I post all of those too?

Slow start up and printer connection

Hi, I have a iMac 10.6.8 which froze up a few weeks ago, so I had to turn the whole thing off without shutting down. Ever since that happened, it is really slow starting up and really slow sending information to the printer. It is connected with the normal printer cable and has always been very quick before the computer froze up. Now it takes 2-3 minutes of the rainbow spinning circle to get anything to print, even just a simple word document! Any clues on what may have happened and how to fix it?
Thanks.

First backup immediately, it is possible you have a damaged or failing HD. Run Apple Hardware Test in Extended Mode and if it reports errors either Google them or post them. If the disk suffered some minor damaged it may be able to be repaired using Disk Utility however you will need to run DU from the original OS X Install Discs that came with the computer, a Snow Leopard upgrade DVD or if you use a Bootable Clone as a Backup you can boot from it and run DU from the Clone.

Time Machine won't back up. Starts of REALLY SLOW, and the errors out.

I've been having a hard time getting time machine to back up. To start off I'll give you my specs and what I have done.
iMac
OS 10.6.6
2.4 GHz Intel Core 2 Duo
4 GB 667 DDR@ SDRAM
320 GB HD
All software updates are current. I am trying to back up to an external Western Digital 1 GB drive connected by USB2. I have formatted the external drive, and set a single partition on that drive from the Disc Utility. I have run disk repair on both the external and local hard drive. I have run disk repair permission on the local drive. I have restarted, after every time. I have done everything listed above multiple times, and have done them all in kinda different orders each time.
My thought is that the issue may not be with the hard drives, but maybe a file its trying to back up. When it starts out for the first time, it tells me that it needs to back up over 100 GB of data. It gets about halfway done, and then errors out. When I try to start it again, it tells me that it needs to backup around 50 GB of data. And this time, its REALLY slow. Like bytes slow, not Mega bytes, or even kilobytes. Bytes. 36 bites backed up, 120 bytes backed up. 2 Kilobytes backed up. SLOW SLOW SLOW.
Then it picks up, and usually gets up to 120 MB, and then gives me this error message "The Backup was not performed because an error occurred while copying files to the backup disk. - The problem may be temporary. Try again later to back up. If the problem persists, use Disk Utility to repair your backup disk."
Its a pretty generic message, and gives me no help in trying to figure out what the problem is. I've been trying again for almost 3 days now, and nothing is working. Is there an error log file that I can go find that would help me a little more?

See #C3 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum).

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?

My Mac suddently started to run really slow a few days ago. I bought it 1.5 yrs ago. It runs on the OS 10.6.8. What to do?

My Mac suddently started to run really slow a few days ago. I bought it 1.5 yrs ago. It runs on the OS 10.6.8. What to do?

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.

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.

IBook G4 starting up really slow

Hello,
I'm having some trouble with my iBook G4. It's starting up really slow. Even if it's only sleeping. I ran a hard drive test, no problems there, it said. The computer starts up and then works normally, but it's a really long wait.
Any ideas what could be the problem? It shows the apple logo and the "moving circle" for a long time. I'd appreciate help!

annasip,
They checked it and found out nothing, and my iBook started up normally there
Doesn't that always happen.
When the computer is having problems starting up, it makes this noise, like the same sound over and over again, sounds a bit like something is stuck. (pretty hard to describe when not speaking my mother tongue)
Uhhh your English is pretty d.. good. As good as most of us around here. Better than my Finnish...suomi something tu...
Anyway that sounds like hard drive problems.
(I just bought an external hard drive so space shoudn't be the problem)
FireWire I hope so get that puppy started up again and Carbon Copy Clone your entire hard drive to your external Firewire:
http://www.bombich.com/software/ccc.html
It's shareware so I have paid them something after using it like 50 times.
Once that's done you should be able to bootg up from your external drive. If that's slow you could try repairing disk permissions from Disk Utility (Did we talk about doing that on the internal drive also?)
If you continue to have problems you might have to repair or reinstall the OS on that external. Don't mess with the internal since it seems to be dying and we want to keep that alive as long as possible.

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.

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.
Mac OS X 10.6 Help: Reinstalling Mac OS X

2010 really slow ~1 min start on test PC -- normal ~1 sec startup on development PC

Okay first my setups
Development PC
I'm running labview 2010 Pro
i7 core, XP SP3
Test PC
2010 runtime
Dual core 2.66GHZ
XP SP3
I'm having a really slow startup on my app on the Test PC. Like almost a minute. It sits there on the taskbar and does not come up. I click on it and nothing happens. I checked task manager and the CPU is at 1% and the app is using about 40MB ram.
I install the exe on the development machine and it comes up within seconds of clicking it? I know I have an i7 competing against a dual core. But when I see 1% I don't see it as a problem. My development PC runs about 4%-10% when the program is running. Maybe 8%-14% on test PC once its up.
The App itself is basically like Intel's UPNP device spy with some automation. All network communication.
Is there anyway to debug this? I know I can add to my app to see what's going on while its running. But what do I do while its starting up?
One other thing, I have is windows IIS installed on the development PC that I was using to send updates to network devices. The Test PC does not have IIS. But my app only checks to see if its running and then moves on. When I turn IIS off on my development PC the app still starts normal.
please help. I'm really not liking 2010 so far. I miss 8.6

Okay so i installed on more machines and they worked fine. Came right up.
So i went back to the test PC and replaced it with a new one, quad core. After the installer was done it asked to reboot for changes. A reboot looked as if the pc was never going to finish. It started to shut down and then would say installing updates and repeat the installing updates part. I turned the pc off and powered back on. That pc took 2minutes to start the app. Finally i connected the internet to the router on the network and the software app started right up.
Is labview embeding some network check? It works like clock work. i unplg the network and it takes forever to start. I plug the network in and it comes right up...
My setup has a routerfor DHCP and a 48 port POE network switch. I do not have the need for internet access. But it looks like im going to be forced to leave it connected to make this start up normal.
p.s. i did unplug the internet while the app was starting and i got some visualstudio.net message error. I dont have visualstudio installed on this pc. Maybe labview runtimes installs it? I did not see it in add/remove programs. This pc is has a fresh xp install with some standard software apps. I'm sure i have .net installed though.
Any ideas? Is labview tracking us secretly Im getting wireshark out tomorrow to see what the network traffic looks like.

Connect the iOS device to your computer and try to make a backup. Yo shld be able to make a backup if you previously syncing to this computer.
iOS: How to back up
Then restore via iTunes. The iOS device will be erased. Place the iOS device in Recovery Mode if necessary to allow the restore.
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.

All of a sudden, my iPhone 5s started to run really, really slow. I formatted it, and it's still running slow. What should i do?

so, my iphone is really slow...

You mean you restored the iPhone with iTunes?
If so, you restored from your iPhone's backup or as a new iPhone or not from the backup?
How much free storage capacity is available on the iPhone?

Start to print and then it prints really slow or stops all together. Desktop computer "Compac"

My printer is an HP DESKJET3050A ALL-IN-ONE J611 SERIES. Operating system installed is Windows XP No i have not made any changes

It sounds like the printer is not getting enough power or there may be a faulty ink cartridge.
To confirm if it is isolated to the printer or somewhere else, try copying a page to see if it is printing slow from a copy.
Is the printer connected to a surge protector? If so, try connecting the printer directly to a wall outlet. Did this help?
The next step is to look at the ink cartridges. An easy test to see if the cartridges may be at fault is to try printing a text only document with the black ink cartridge removed.
Did it still print slow? It will still be slow since it will be mixing the colors to make black, but it should be faster than it was before if a faulty cartridge was at fault.
If it still print really slow with the black cartridge removed, try putting the black back in and removing the color cartridge. Did it still print slow?
Let me know what happens.
