New 27" iMac taking ages to boot up and shut down

i JST bought, literally a week ago, a new 27" imac core 2 duo and it takes forever to boot up and shut down
boot up: 30 - 40mins
shutdown: undetermined (shut down at 1am, was still shutting down at 7am when i got up for work!)
anyone any ideas?

For the startup part, I would reset PRAM
http://support.apple.com/kb/HT1379
and once it gets to the Desktop, open System Preferences +Startup Disk+ pane. Make sure your internal drive is selected (highlighted) as the startup disk choice.
Not sure about the shutdown issue, since there are many potential causes. One could be a running process that is having a problem quitting. Try starting up and then immediately shutting down (give it a few minutes to fully start up but shut down before you run anything else). Does it shut down quickly, or do you have the same problem?

Is Lion slow booting up and shutting down?

After I installed Lion, my macbook pro is slow to boot up and shut down. How can you turn off "re-open windows when logging back on"?

The beeps on startup are often indicative of RAM problems. The opening chime is the only normal noise on startup. Shutdown should be essentially silent. To the Apple store, PRONTO!
Ciao.

Why is it slower to boot up and shut down

For the last few months, at least since I updated to Mac OS 10.7.3 (this may not be related), I have noticed that the boot up sequence is a lot longer (4 to 5 times) than it used to be. Although not as extreme, the shutting down sequence is also taking a lot longer than previously. My software updates are always done and I run VirusBarrier X6 and BOINCManager in the background. Is this normal or is this symptomatic of a problem? Thanks

It's symptomatic of a problem. You might start with:
Boot into Safe Mode and do the following:
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. When it 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.
If this does not help then create a new user account. Log into the new account and then see how startups and shutdowns go. If things have improved you have issues created in your normal user account.
I would also suggest uninstalling software like VirusBarrier. Unless you require BOINC software I'd uninstall it, too. Also, check your Login Items in Users & Groups. These can prolong both startup and shutdown.

IMac does not like being connected and shuts down

A white 17-inch iMac belonging to relatives of mine has started to behave rather oddly. In particular it does not seem to like to be connected to anything. Once when set to run in Fire Wire–hard drive mode it had just shut down and restarted itself in normal mode. And now when I try to start it with an Ethernet cable connected it just turns black shortly after the start signal. If the cable is removed it starts as it should (most of the time anyway – sometimes I have had to pull the power plug for a while or do a PRAM reset).
In addition, once when I pressed the switch on the back to start it up there were repeated soughing sounds, as if it tried to start over and over again. When the power plug had been removed and reconnected the Imac started directly, without the switch being pressed.
Finally, once when I tried to wake it up from sleep mode it shut down too. What is wrong with it?

So, I tried the old ADSL modem and router again, and now the iMac seems to work fine and connects to the Internet without problems. (The reason this equipment was exchanged in the first place, some month or two ago, was that somebody felt that new technology should be used, something by means of which your telephone calls too are transmitted over the Internet. Well, obviously it did not work, at least not with this piece of junk that Telia (our previously national Swedish telephone company) sent.)
Now the only thing is that although the iMac seems to work fine obviously some damage has been done to it, since for example it shut down from target disk mode (without any Ethernet cable being attached). I do not really know how to address that.

Late 09 iMac 27 will not boot up then shuts down

Second occurrence of this issue in roughly 2 months:
1st time: pre-Mavericks
2nd time: after HD reformat and Mavericks install, both at Genius Bar
I get the tone, logo, gear, progress bar to roughly 10%, then shutdown. I cannot even get into safe mode or try disk utility. The various resets (pram, etc...) do not work either
I took it to the genius bar and they reformatted the HD and all was well for a couple of months. I do not have any 3rd party SW except for iBank, MS Office, and printer drivers. As with the first time this popped up, I had a couple of warning reboots before this. I was able to save my large iPhoto file.
So, is this a HW issue? If not what SW problem would cause the same issue again if the HD was reformatted once already?
Debating pitching the iMac and going Mac Mini, all we use the Mac for is finances,email, and iPhoto.
Thanks for any thoughts or suggestions.

Satellite C660-106 wont get past boot screen and shuts down

hi all new here
well we have had our c660 106 for 2 month now,but the missus decided to drop it from about 6 inches high, it stayed on but the led screen is cracked internally as the colours were bleeding over etc,unwatchable.
It stayed on untill today and ive been pricing screens up.(had it connected through rgb to my home lcd)
i had to unplug the laptop and turn it off,but now the problem is when i switch it on it will do the inital fire up to the toshiba black screen where i have the options 0f f2 and f12 but then immediately turns off completely, we are worried now as we have a 1 yr old and we have everything she has ever done on there,
is there anything i can try
i know warranty wont cover it as its obvious the screens broken and not just failed.
any help would be brill
thanks

Hi nicolas221078_1
This sounds to be some damage to the motherboard or cooling system and this is why it is now turning off all I can say is are you able to access the BIOS if so then it may be the HDD but if not then you will know 100% it is the motherboard.
If the HDD is ok then you can take it to a data recovery service that should be able to recovery most or all of the data that is stored on the HDD.
also just another thing to point out is to check the memory is sat correctly in the laptop this will not cause any issues with a warranty, also have you though about contense insurance they may cover the damage laptop.

HP PAVILION NOTEBOOK N5190 FAILS TO BOOT-UP AND SHUTS DOWN AFTER POWER SWITCH TURNED ON...

When I press the on switch slider, the notebook shows lights then CPU fan begins to spin. It immediately slows down then stops. Power light stays on, but nothing else happens. No startup screen, nothing. To do it again, power cable must be disconnected then reconnected. Does anybody has any idea? Please help.

Once you get it to turn on, I would check to see if there is a BIOS update available for your machine.

Slow booting and shut down. How?

I just bought my macbook pro 13" just a month ago, and now the motherboard has crashed. Sent for repair and is useable now, but the booting up and shutting down took longer than before. What should I do?

Hey Joseph! Thanks for your help. Now the shutting down seems to be faster by a bit. But it still shows the blue screen which i hate to see. Starting was as usual slow.
The only program that needs running upon start up was MSN. And it usually doesn't gets signed in by itself even when it's checked at "auto sign in". And I'm not sure if msn itself is having any issue, or has it got something to do with my mac, because sending messages online was kinda terrible. There were many times where I typed a chunk of messages and after 5-10 mins then they told me that it wasn't sent at all. Plus it keeps logging me out. SO ANNOYED.
And lastly, safari web browser KEEPS CRASHING. that i have to force quit it many many times. I wrote to Apple support alr. Hope that they will get back to me soon abt this. It's kinda frustrating to use it when there are so many issues whereby I don't even know the cause of.

Extremely slow boot and shut down

I've been experiencing VERY slow boot up and shut down times (in excess of one minute for both booting and shutting down). I've removed everything from my login items and I still have the same problem. I have a late 2007 black MacBook with 10.5.3 on it. Any help would be appreciated!

Try running a cache cleaner and clear out all system and user cache files. Onyx is a good freeware application for this. There are several others of course.

I am going to load windows 7 via Boot Camp for other reasns. After that is done, and even with an external Blu Ray player, is it still not possible to play Blu ray movies?
Thanks for your consideration.....

Will the new 2012 iMac support 2 hard drives (HDD and SSD) like the 2011 iMac?

Will the new 2012 iMac support 2 hard drives (HDD and SSD) like the 2011 iMac?

Well, I'm not sure how anything can fit into a 5 mm depth, so I can see why they've removed the CD drive - there probably wouldn't be enough room for the laser, LOL. Can't imagine speakers, hard drive (of any flavor), logic board and so on and so forth. Fortunately, my iMac has Applecare through early 2015 so I'm set for a while; I may check out a Mini at that point - saw that it is configurable with a fusion drive, which would make it interesting for me.

That means your iMac could not find a system to use for startup. That may mean the internal hard drive has become faulty, or the hard drive mechanism is fine, but the startup volume ("Macintosh HD" unless you renamed it) may have some type of data corruption that makes it unbootable.
First, you should try resetting PRAM
http://support.apple.com/kb/HT1379
and if that does not help, use this procedure to reset SMC (power management). If your iMac is from 2008, this is the procedure for Intel (not PowerPC) Macs.
http://support.apple.com/kb/HT3964
(This forum category is for "iMac (PPC)," so if this iMac is older (with a PowerPC processor), please post back.)
Disconnect all peripheral devices. When you connect it back to power, if you have been using a power strip of some type, try connecting it directly to a wall outlet, by itself (at least initially). Start up with nothing but the power cord connected, then add only standard mouse and keyboard. If it works, run it that way for a while.
If PRAM and SMC reset have no effect, you should insert your Mac OS X installation disc (for the currently installed system) in the optical drive, and restart with the C key held down. This should get you to the Installer screen, where you can run Disk Utility from the Utilities menu.
In Disk Utility, does the internal hard drive appear in the sidebar? If so, select Macintosh HD in the sidebar and go to the First Aid tab. Use Repair Disk. If an error is found, note if Disk Utility was able to fix it or not.
You can then quit Disk Utility and attempt to restart normally.

Just done a fresh install of Snow Leopard with all updates,iMac 5.1 behaves strange, sometimes I start Google Chrome and look at youtube videos the computer freezes and shuts down immediately, I believe its related to overheating ?

Just done a replacement of the pata DVD drive (its new and is working ok), and a fresh clean install of Snow Leopard with all updates, iMac 5.1 behaves strange, sometimes I start Google Chrome and look at youtube videos the computer freezes and shuts down immediately,
I believe its related to overheating ?
iStat Pro shows GPU diode temp at 66 C, CPU at 48 C, Fan rpms is around 1000
Any ideas somebody ?
The hard disk has been previously checked with state of the art techniques that have confirmed that the hard disk drive is in perfect condition.

1.5-3 minute boot up as opposed to 15-20 seconds
And
why it takes a long time to load a lot of things.
I have restored this
from a time machine partition.
TimeMachine is only a backup and restore, it won't fix issues in software and according to your information, doesn't even optimize the restore for best performance on boot hard drives.
What you need to do to regain your speed is to understand how your machine works
Why is my computer slow?
Fix any and all issues in software following this list of fixes
..Step by Step to fix your Mac
Then follow this defrag method I've outlined
How to safely defrag a Mac's hard drive
Most commonly used backup methods
There shouldn't be need to reinstall OS X fresh unless your having file structure issues which if they are should appear when in the Steps, which then a zero erase and install will cure as well as any bad sector issues, the defrag step wouldn't be necessarry on a freshly installed system obviously as the files are written all together, not in portions all over the drive.
Hope this assists.

MacPRO boots and shuts down in 1 motion

Evevning forum,
After returning home I have tried to bootup my MacPRO (early 2008) and the machine is acting weird. Before I left all was working fine. It seems as soon as I press the start button the computer tries to power up and shuts down straight away, within in seconds. Could this be a power supply issue as many seem to have fallen fate to this issue. If so wha are the cost of a new one?
Thanx in advance

Was it plugged into a UPS?
Was it unplugged from power?
Have you tried an SMC Reset?
