Huge problem, not able to boot after shut down.

I just updated the Firmware 1.8 to eliminate the optical drive noise, thought my computer would restart but it said it wasn't necessary. So I continued using it, writing a document. I had Safari, Pages, Mail open-- I opened up PhotoBooth to take a picture of my brother and I and my computer stopped responding all together. Eventually I had to shut it down by holding the power button down for 5 seconds. Ever since then when I try to restart it- it will not move past the Apple logo screen with the spinning cog. I have tried to boot from a leopard install disc (holding down 'c') and it just keeps restarting. I've also tried to boot a Data Rescue program, and again it just keeps restarting- like it will not boot at all from the CD drive. Can anyone help? Thanks in advance

Just tried to boot in Safe Mode and it wouldn't. Also performed the fsck check until it said my hard drive was ok- and it is still performing the same actions. Thank you for the reply. Is there anything else you can think of?

My mac is not able to boot after internet recovery

Hi I Own an i mac27 inch which i bought in year 2011. Recently it showed some disc errors and got crashed with a blue screen. I was not able to boot it in a safe mode and had to remove my data via a thunderbolt cable. After removing the data i formatted the hard drive with mac format thinking that would remove the bad sectors. But I realized it wont even start up again in a recovery mode. So i tried to boot it via a bootable USB drive. Now When i press Command+R i get only two options (1. Bootable OSX Drive, 2.Internet connection) None of the options are of any help. Any suggestions??

Hello nachi777,
Thanks for using Apple Support Communities.
From your post it looks like you are trying to reformat your hard drive, but are unable to boot into recovery. Since you have a newer iMac, you should be able to boot to internet recovery. Booting to internet recovery occurs automatically if your startup drive has an issue. If you are seeing boot drive options when starting up, then you may just be holding down the option key on the keyboard. Both options you do see to boot from, should be able to help in reformatting your hard drive.

Yesterday my track pad went haywire. My pointer was all over the place and my screen would not stay still. After shutting down and trying time capsule I still had the problem. Today it's as if nothing ever happened

What causes the trackpad and screen become jittery and hard to control. There were no sticky buttons and no visible reason for the malfunction. I tried resetting with time capsule and shutting down with no progress. Later I booted to Windows to see if it could be hardware but my pad worked okay there. WOW. Today I open Mavericks and everything is fine. Anyone might know of a cause?

Hi Raphix43,
I am glad to hear that your issue with the MacBook Pro’s trackpad has gone away. Should it return for any reason you may want to use the steps in the following article to troubleshoot -

How to auto boot after shutting down bootcamp Windows?

I have an instructional lab of 30 20" imacs that are running dual-boot, 10.5 & XP SP3. They have bootpicker installed to simplify the selection of which OS to boot to and auto-select Windows at 60 sec. (This is for new computer users and English as a second language users that are not familiar with the dual-boot setups.)
In both OS's we run deepfreeze to protect the configurations from change. I have set the Energy Saver settings in the Mac OS to start or wake at 7am weekdays. Deepfreeze for Windows is set to shut off the Macs at 10PM. This is also set by Deepfreeze in the Mac OS but since they primarily run Windows in this classroom the Mac's are shut down from the Windows side.
After making the auto start setting and shutting them down from Windows once they will no longer auto start the next day or ever again after that. I have tried using pmset to remedy this and have tossed the plist for the settings numerous times. Same thing every time. One auto boot and then none after. I would use a script from ARD to wake them but they are not in the same subnet as my ARD setup and my network group will not configure our switching to allow for it.
Does anyone know how to make the Macs boot consistently, automatically, every day I wish them to boot after being shut down from Windows by Deepfreeze.

Power Mac G4 MDD - Has difficulty booting after shut down

I have a Power Mac G4 MDD (1.25Ghz) that is having issues when it is shut down. The power button on the front of the machine does not start the computer every time. Sometimes it works, sometimes I need to wait a while before it will work. When the button is pressed, it does not light up or anything.
I have noticed that if I sleep the computer it always seems to wakeup when the front button is pressed. But if I shut down the G4, is does not always bootup.
I have also performed multiple restarts when performing software updates, and they always seemed to work fine.
I have changed the Saft battery inside - it was at about .4v
I have performed a CUDA/PMU reset using the button on the motherboard, and followed the Apple procedure. (disconnect power, and accesories, press reset button, wait 10 seconds, reconnect, restart) It did not restart right away, had to wait 20 minutes or so.
The G4 has a new installation of Tiger, with all of the updates.
I have not checked the PSU, but plan on doing that soon. Just seems odd that it only has issues when the machine was shutdown. Seems to start after it sits for a while, but last night I was switching monitors, and shut it down, switched monitors, and it would not re-boot.
Any ideas?

With the "sometimes" nature of the problem, it could be the front panel board, a much cheaper replacement than a PSU. An Apple tech told me that one way to test the front panel board was to find one of the first Apple USB keyboards for the original iMac. The early ones have a power button like the old ADB boards that overrides the internal board/button. He said that, should the Mac start reliably from the old keyboard, then there is trouble with the front panel board. The Apple model number for the USB board with power button is M2452.
Very helpful forum member japamac has a test procedure for the MDD PSU on his site here:

You'll need a multimeter to check the voltage levels.

Not able to boot after updating to 10.5.1

Hi all,
Have been running 10.5 on an external disk having left Tiger on the internal.
After updating to 10.5.1 the system doesn't boot at all. I get the grey screen with the apple symbol and NO spinning "wheel". I have to re-boot from the install DVD to be able to change the start volume to 10.4.11. From Tiger I have tried to change the start-up volume to 10.5.1 again but still the same problem, in some cases it goes back and starts Tiger even if I set the volume to Leopard.
Re-installing 10.5 doesn't change anything, the older version behaves in the same way.
I suspect it must have something to do with booting sequence.
Any suggestions ?????

If you're comfortable with opening things up you could take the drive out of its case and plug it into the ide cable inside the G4 along with your existing system drive. (Assuming this is a G4 tower)
To be on the safe side you could just swap it with your current internal disk and see if it boots as well.

MacBook slow; results in a freeze and inability to boot after shutting down

From time to time my MacBook starts getting slow. This always results in a total freeze, to which my (as far as I can tell only available) reaction is always powering it off with the P-button.
However, after I shut it down it always gets stuck at the loading screen when trying to boot again. I've experienced both a grey screen with spinning gear and a white screen with spinning gear. Usually a Pram-reset allows me to boot, but lately it has taken days and countless different fixes to get past the starting sequence.
This morning I spent 3 hours resetting every concieveable thing, booted in safe mode, did a disk repair, but to no effect.
Initially I couldn't even do a Pram-reset (it would just boot regularly without a second chime).
Later I was able to, but again to no effect (it would just get stuck at the grey screen).
I ended up leaving my MacBook for a few hours to 'rest'. Upon returning home I did another Pram-reset, and this time it booted normally - it just seems so random that it would suddenly work.
My question is: what can I do to prevent this in the future? The sudden drop in performance resulting in a freeze?
Thanks in advance,
Kris

Hyper V feature in Win 8.1 after getting installed , system is not able to boot up

I am using Windows 8.1 professional x64 os in my Hp pavilion G6 laptop which has virtualisation technology enabled in the bios , but after enabling hyper v feature in the windows system is not able to boot up and circles around for a long time. I need
hyper v on my laptop , kindly help me out for the same.

Hi,
Please try to boot into WinRE and run the Startup Repair option.
Generally speaking, when you add feature like Hyper-V, system would take a long time to get this feature configured. if your computer still stay updates configuration steps, you can use Windows 8.1 installation image to repair system. In system repair mode,
you can access into Command Prompt mode, and check CBS.log under C:\Windows\logs\CBS.
This log file would record Windows installation process, we may find the problem of Hyper-V installation.

In 2 node RAC. After shutting down database not able to connect.

I have 2 node Oracle 10g RAC (RAC-1 and RAC-2) on Windows 2003 Server.
After shutting down instance on RAC-2
I am not able to connect to database from any node.
I did this on RAC-2 :
SQL>shutdown immediate;
Database went down smoothly.
SQL>conn sys/oracle@rac as sysdba
ERROR:
ORA-12514: TNS:listener does not currnetly know of services requested in connect descriptor.
My first node is running fine but I am not able to connect to database from first node or from client.
Any suggestion???
Regards:
Sushil

One question I want to ask, what should be the Listener Services startup mode in RAC? MANUAL or AUTOMATIC???Ideally, if you are instances and other oracle resources are set to autostart then there is no reason for you to set the listener to MANUAL. You may like to change it to AUTOMATIC so that on reboot it comes up without manual intervention.

Mac Pro not able to boot into 64 bit kernel?

Hello,
I've been trying to boot while using the 6 and 4 buttons held down to no avail. This mac pro was bought in 2007 (work computer). Am I not able to boot into 64 bit mode with Snow Leopard? If so, does that mean I can't take advantage of the 64 bit kernel?
Thanks,

Man, Yes, when I am rendering all 8 cores in Maya, up to 4 gigs of ram are being used. Why is that so hard to believe? I should be able to render in RAM preview in After Effects a whole lot more than i can now without cacheing.!!!!
Is Maya a 64 bit application? If Maya is not using more than 4GB, than you should be talking to the Maya developers.
You should be able to use Applications -> Utilities -> Activity Monitor and look at the "Kind" field. If it says "intel (64 bits)", then it is a 64 bit application.
How many times do I have to state "YES, I will be using more than 4 gigs of RAM per program"?
Why is it the tech people really don't understand how intensive program dynamics like Maya and Blender are,
You are responding to my post, so I'm going to say, I have been working for major computer manufactures since the early 70's working with "Big Iron" computer systems, not PCs, and I most likely know a lot more about how computers work, then many computer users. Please do not tell me I do not understand. I've been working with 64 bit code since the early 90's.
and yet Apple touts their excellence in 64 bit programs like AFX, yet, I can't use more than 4 gb of RAM?
Are you saying AFX (is that After Effects?) is not a 64 bit application yet? If not, then I suggest you talk to Adobe, not Apple.
Just for fun, I wrote a sample program, which allocated a large amount of memory. I ran it on my iMac with is booted with a 32 bit 10.6.2 Snow Leopard kernel. Here are the results:
PID RESIDENT VIRTUAL PageFlt Reclaim COMMAND
54296 4.74G 9.32G 0K 0K tmp
My program has more than 4GB of physical RAM (4.74GB), and a virtual memory size of 9.32GB.
If I use Activity Monitor, I can see that my program is listed with a Kind of "intel (64 bit)".
So if Maya cannot use more than 4GB of memory, it is a Maya problem. Talk to the Maya developers.
We aren't cows Apple. We are people with limited money trying to make it in the world. Not every mac pro user is a business and we don't want too much control.
You are not talking to Apple, just other Mac users. If you wish to tell something to Apple, I would encourage you to use either:

I'n not able to boot Osx 10.6 from Firewire Hd if I use USB yes ... Why?

Hi ,
I've problem with the internal hd of my Imac. The option is to change de HD or to use an external HD to boot from.
At the Apple store they showed me the possibility to use a firewire HD to install and run the system on my mac . I already had a firewire HD , a WD my passport studio, but I'install easoly the operative system on the HD connected by a firewire but when I need to reboot the system doen't recognize any operative system. If I reboot using the USB is OK but not with the firewire ... so I can install OSX on a firewire but I'm not able to boot using the same connection , I have to switch to USB... Somebody can help me? I read something about some problems that Snow Leopard have with firewire ... maybe using lion can be better?
Thanks and sorry for my grammar mistakes

It is free. It is beta. It works well - I use it on mine and two PCs as well...
MS Security Essentials will no longer install due to compatibiliity issues - that is the idea of a beta - and the RC could be out in June.
Windows 7 doesn't work great on any Mac, or Apple drivers, fan cvontrol to manage heat, and other issues.
Put 8 in and get to know it, then when the RC comes out you'll be ready

Can you mention the steps you used before running the ales_install script? Which WLS version are you using for Admin Server? Is it CP3 or CP4 patched?

If it is one year old minus one day it is still under warranty. If it is more than a year since you purchased it then yes, the warranty has expired.
Millions of iPads have been sold. Most continue to function long after their warranty has expired. Check the many requests about updating the iOS on the original iPad on these forums and you'll see that there are many iPads still working after three years. My iPad 2, which I had for over two years is still working well for my son in law who took it over from me when I bought a new one.
Given that there will always be a few iPads that fail early. Most of those will be covered under warranty. But some will fail after the warranty has expired and before the owner expected it to. I'm sorry to hear that you are in this category. Take your iPad to an Apple store and have it looked at. They will provide you with alternatives, one of which is to purchase a like model to the one that failed at a discount. You can then know your options and make the best choice for you.

Huge problem, not able to boot after shut down.
