IMac 27 slow start and KPs

Hi friends,
I've got a 27 inches iMac from January 2010. In last month i'm experiencing very slow starts in first white screen. The start takes about 2 or 3 minutes.
Then, in desktop, all is OK. I work very good with all programs and games. I'm not experiencing any problem with videocard, memory, hard-disk, or somthing.
Two or three times I try to Shut down the iMac, OSX put a screen making me to shut down holding down the bottom to start/stop for a few seconds and restarting the system. Then, the iMac show me this KP:

Things I've done:
- Try to repair users and disk permissions with Onyx.
- Try to unplug all USB devices plugged in back USB (ex. AverTV or Printer)
- I've updated the OSX to 10.6.7
Things I suspect:
- In desktop the mouse or keyboard doesn't work until I press some buttons. (Maybe Bluetooth problem?)
- Two months ago I've got a problem with Espionage Software, making some folders invisibles with encryptation, deleting the app, reinstalling and some folders encryped maybe causing problems?
- I can't restart with 'D' pressed for a Hardware Test (Maybe same Bluetooth problem?)
- Maybe I may to move the RAM between sockets?
Could someone guide me for what can I do?
Thanks!

Most likely, com.avermedia.driver.A815(1.1.10)@0x5f83d000->0x5f85dfff is the culprit. Additionally, these also have to be looked into:

IMac running slow (Etrecheck in post)

Problem description:
iMac running slow, Finder becomes unresponsive. Over the last 5 years I think I've installed and removed so many programs that I've left OSX a mess. I know enough about computers to confidently make mistakes. The memory and cpu are not maxed out in Activity Monitor, yet I'm getting beach balled.

Slow start up / "ghost programs"

I had some trouble with my harddisk when it filled up and became slow, so I made a clean install and copied back my things from Time Machine. But, and this problem happened before that too, my iMac takes forever to startup (about 5 minutes).
And every now and then a program (mostly iTunes) will become non-responsive, but apparently shuts down in a normal fashion when I close it. But the symbol in the dock will say it's still running, and in a mystical way... it is. Because force shut down doesn't work, neither with any program or a restart of the finder, and the only thing working is to do a cold restart of the machine. Interestingly, the activity monitor doesn't find the programs that hangs either, even if they are running.
I don't understand a thing right now...

1. Check your Startup Disk. Go to System Preferences/Startup Disk and make sure that your Mac OS X system drive/folder is selected as your startup disk. Otherwise the system could take longer searching for it every time you boot.
CHECK
2. Repair Permissions. Open Applications/Utilities/Disk Utility select your hard drive on the left and under the First Aid tab click Repair Disk Permissions.
CHECK
3. Verify Disk. While you are in Disk Utility after you Repair the Permissions click Verify Disk. This will check the integrity of your volume directory. If there are any errors that need to be addressed you will have to boot up to your install disk in order to run Repair Disk.
CHECK
4. Check your login items list. Go to System Preferences/Accounts/Login items. If there are any Applications there that should not be simply remove it from the list.
CHECK
5. Disconnect any external devices for testing purposes. External hard drives, ipods, scanners, printers, have been known at times to cause startup/shutdown issues.
NOT DONE YET
I've bought a new 1 TB MyBook today so I can remove a Maxtor-disk I have who's been difficult to read from (it doesn't always appear in the Finder), so I'm moving my music and different stuff right now and I'll have to wait some time to do a startup without external disks. In addition I have a 500 GB LaCie with two partions (250 on each, one for Time Machine) who seems to work fine.
It's the actual start up which is the problem, not the login process.
I can live with the slow start up for now, but my main problem is when iTunes and Xtorrent freezes and starts acting like a ghost. Any ideas there? It just happened with Xtorrent again now. It's shut down, but the dock indicates that it's still running...

My iMac does not start.

My iMac does not start. When I turn it on, it stays loading in the half and doesn't continue. Some days before I had updated my iMac to Yosemite 10.10. Everything was ok but yesterday I decided tu reboot it and when it was turning on this happened, it kept stuck at the middle of the bar. I have the latest model of MacBook Air '13.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. 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. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

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.

B210a is very slow started to print wirelessly

I recently purchased a B210a which I'm using wirelessly from my Apple iPhone, iPad, and a Mac. It takes over a minute to start printing from any of these devices. I've now connected a cable from my iMac and it is still very slow starting. Any suggestions?

Tell me about your network - router brand/model, encryption type (WEP, WPA, etc) and ISP type (DSL, Cable, etc).

IMac will not start following OS X 10.9.4 update - takes 30 minutes to load and then turns off

iMac will not start following OS X 10.9.4 update - takes 30 minutes to load with spinning wheel and progress bar and then when it appears to be finished it powers off?

Thanks for the suggestion - this was the 1st thing I tried but it does not appear to work either. I'm still getting the 30 minute spinning wheel and slow moving progress bar on a grey background - even if I try to start the iMac in 'safe' mode!

My iMac is slow accessing web sites.

My iMac is slow accessing different web sites. I also have a PC that doesn't seem to have the same problem. Any suggestions. All other programs on the computer run fine. This has only started about a month ago. Any suggestions?

If Safari is getting very slow:
(Presumably you regularly empty your Safari cache by deleting the following file:
Home/Library/Caches/com.apple.Safari/cache.db
and clear your History)
Adding Open DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security, including anti-phishing and redirects) (Full information about Open DNS is here: http://www.opendns.com/home/nobloat )
If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
208.67.222.222
208.67.220.220
(You can also enter them if you click on Advanced and then DNS)
Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:
http://support.apple.com/kb/TS2296
If your computer is part of a network:please refer to this page: http://www.opendns.com/start/best_practices/#your_network and follow the advice given.
If you use a Router, make sure it has the latest firmware installed.
One reason for a slowness in page loading may be the 'DNS Pre-fetching' feature of Safari 5.x as is described here:
http://support.apple.com/kb/TS3408?viewlocale=en_US
You can cancel DNS pre-fetching by going to Terminal and typing:
defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false
You have to restart Safari for it to take effect.
If Safari seems to hang for ages:
If you have a lot of tabs open and/or a lot of pages running Flash, Safari can sometimes 'hang', requiring a restart of Safari. This can often be inconvenient, and as it is rarely Safari itself that is hanging but merely one of its plug-ins, usually Flash, there is a way using Terminal to restart the plug-ins (without restarting Safari and losing your tabs) by quitting the WebPluginHost process:
Open the Terminal from the Utilities folder in /Applications and type
killall -9 WebKitPluginHost
Note that this command kills all Safari plug-ins, not just Flash. All plug-ins should start back up when you reload the page.
Then go back to Safari and refresh any pages that were using the Flash plug-in. This also fixes the Beachball of Death. Try this whenever Safari gets slow or freezes. The latest versions of Flash 10.1 appear to have improved the situation somewhat, but haven't completed eliminated it.
For this and other reasons Apple switched their websites to HTML5 in January 2011:

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!

My 27" i7 iMac is slow

My 27" iMac is slower than my first issue MacPro I in all ways, starting up, editing in FCPX and entering Mail or Gooogle. Very frustrating. I have Motion and Compressor but haven't got them in use. No other progs are present to be blamed. Everything to a bare minimum; only FCPX to be used. The iMac has the original eequipment except for the ram which is the maximu, 32gb.
I not that a previous entry on this issue is locked so. - help anyone?

IMac freezes on start

Around a week ago my iMac, which is usually always on, would not wake from sleep (screen was black) and I had to hard reset it. However, it could not start up. After the apple logo appears on the grey screen and the tiny circle of dots flash to indicate that is loading, the 'dot circle' suddenly froze. The only option was again to hard reset it.
Since then, I have tried to restart it maybe 30-40 times and it is (almost) always the same symptom; relatively slow start (30 seconds or so) and then suddenly it freezes before coming to the login screen. Twice, the computer managed to start-up properly but shortly after the top part of the screen started to flimmer and the remainder went black and only a hard reset could get it out of its misery. But this has not happened since; now it just stalls during the grey screen start-up.
The iMac is a 24" from early 2008 (model EMM 2134) with 2,8GHZ and 4GB ram (apple supplied). About two years ago the hard drive failed and I had to replace it with a new one but this is the only modification I have applied. It runs OSX 10.9
To resolve the issue, I have been through various error checks that have not helped
- No visible or audible defects that I can discern
- The power supply inside the iMac does not seem to be broken (I opened and checked)
- Removing the two 2GB rams blocks one at a time does not change start-up behavior
- Booting from USB recovery or from an install DVD in the optical drive using either the C or D key during start-up does not help
- Starting in SAFE mode and enabling logging showed an SMCreadkeyaction ERROR
- Tried resetting the NVRAM (http://support.apple.com/kb/HT1379) and the SMC (http://support.apple.com/kb/HT3964.).
- Apple Disk Utility test and recovery (via another mac in firewire mode) turned up no fautls.
- Formatted HD and installed OSX 10.5 on the HD (via firewire on onther mac). Still no change.
I am a bit at a loss what could cause this problem; it does not seem to be harddisk related (though this cannot be ruled out), it does not seem to be the graphic card despite the occasional flimmer as most of the time, the screen looks just fine (including the firewire icon dancing around when I had in T mode); and if it had been the power supply would it not have had visible marks of burning or bulking condensators?
Qualified suggestions as to what might be wrong or how to keep testing would be greatly appreciated.
Thanks
Dan

An Apple repair station visit is in order.

My iMac doesn't start.

My iMac doesn't start. It chimes after pressing turn-on button, but it stays on the screen of white background, apple logo in the middle with the pointer going round and round and round, but doesn't move to next stage. Please let me know what to do...

I am having the same problem. I got on last night to the same info and tried all that. None of it worked. My Mac had been running slow for a few weeks, so I restarted it and then it wouldn't power back on. The gray screen just keeps coming on and then it just shuts down.
To doctor; I have sent a request to have apple call me to try to resolve issue. Maybe you should try too. Best of luck.
