Imac running 10.8.2 often does not start up with firewire drives connected

I have a mid 2007 imac running osx 10.8.2 and it will nit restart with two firewire drives connected if it has been running for sometime. If i disconnecr and restart and then connect the drives and then restart again it will restart.

a brody's guess is a good one. Please also look at what Apple says in Gray screen appears during startup

Not running Leopard (Panther), but I have a similar problem on my 24" iMac. Computer was working fine last night (I shut it down) and when I went to boot up this morning the computer is stuck on a black screen.
The boot up sound is initiated but nothing after that. The power light stays at full brightness, if I touch the power button the light blinks and then after a while it goes out. A full reset does nothing. I've tried reseting my PRAM, which works because I hear the start up sound twice, but no change to the black screen.
I don't have access to another Mac, would inserting the Startup Disc I received with the computer do anything?

T400 does not start up with a battery and AC, but starts up with only AC.

I bought T400, 7417-CTO in Jan 2010. My T400 does not start up with a battery and AC power. I tried to start with only AC power after pulling out the battery, it worked fine. Even when I inserted the battery in T400, which was running perfectly with AC only, T400 seems to lose the power - more strictly speaking, it kept stoping and re-running several times, and finally it dead.
a few possibilities
1) a battery is dead - but it does not explain the failure with both AC and battery
2) some hibernation issue - I plugged in and out the DIMM, and clock battery. I tried to keep pushing the power button trick, but it didn't work
3) Mother board failure??
I really appreciate if you give me some advice on it.
Wanyong

Thanks for all your kind and helpful comments.
Unfortunately, I don't have any friends who have Lenovo - or I don't have many friends here since I moved in the last summer. ;-)
After purchasing a new battery, I will update it. Hope that this thread helps someone who had/will have same prob. as mine.

Does not start up with last viewed Tabs even though chosen in options?

V 4.01 with Vista. Even after choosing the correct option in options>options>General FF does not start up with the last session of Tabs and Windows. It always opens with a single blank Tab. What am I doing wrong?

Make sure that you do not use [[Clear Recent History]] to clear the "Browsing History" if Firefox is closed because that prevails and prevents Firefox from opening tabs from the previous session.
If you use CCleaner then make sure that Session is unchecked in the settings for the Firefox application.

Time Machine does not start after external hard drive is connected

Time Machine does not start after external hard drive is connected

These are the iCloud storage options: http://www.apple.com/icloud/includes/lightbox-storage.html
Also bear in mind that:
1. restoring data over icloud takes time
2. iCloud is not designed as a replacement to Time Machine.

Xorg does not start (timeouts) with "no screens found"

After years of my system working correctly, this has been happening for the last ten days.
Many times - not all of them - xorg does not start, and I get greated with the standard console login prompt.
Checking in /var/log/ the xorg.0.log, it says that "no screens found".
I am using an nvidia VGA with nvidia driver 190.xx from extra.
I am using KDE, from inittab (not with kdm as a deamon).
Initial xorg.conf used to be:
Section "ServerFlags"
Option "AutoAddDevices" "False"
EndSection
Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
EndSection
Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "CoreKeyboard"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
EndSection
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ExplorerPS/2"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "true"
EndSection
Section "Monitor"
Identifier "My Monitor"
Option "DPMS" "True"
Option "DPI" "96 x 96"
EndSection
Section "Device"
Identifier "My Graphics Card"
Driver "nvidia"
VendorName "NVIDIA Corporation"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "My Graphics Card"
Monitor "My Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24

EndSubSection
Option "DPI" "96 x 96"
Option "AddARGBGLXVisuals" "true"
Option "TripleBuffer" "true"
EndSection
Section "Extensions"
Option "Composite" "enable"
EndSection
Now I have trimmed it down to:
Section "Device"
Identifier "My Graphics Card"
Driver "nvidia"
EndSection
But the problem remains.
The problem started ten days ago.
The previous night I had updated the following packages (I provide a section of pacman.log):
[2010-01-21 20:35] upgraded acct (6.3.2-2 -> 6.5.1-1)
[2010-01-21 20:35] upgraded coreutils (8.2-1 -> 8.4-1)

[2010-01-21 20:35] upgraded whois (4.7.36-1 -> 5.0.0-1)
So since nothing on xorg was updated, maybe the new coreutils is the more likely suspect?

no, i install nvidia and then xorg i try startx without result.
Right now i am from Ubuntu, i am going to install arch on virtualbox and i will answer to any other questions.
Thank you
The reason you were asked if you rebooted is because installing the nvidia driver also installs a kernel module. That kernel module
needs to be installed in the running kernel, either by invoking "depmod nvidia" or rebooting, providing everything installed correctly. You
may need to put the module name in your modules section of rc.conf and then reboot.
The absence of that kernel module explains your error message of not finding that kernel module. :-)
iirc the .install already does the depmod
Note to TS: if you use virtualbox you can't use your hosts video card so you will have to use the vboxvideo driver. So read the wiki about virtualbox

IPhoto does not start up with incompatible Prokit error

i installed the new version of iphoto 9.3 ( as prompted by software updates). post installation, iphoto does not start up. it throws an error " incompatible prokit framework".

I have Mac OS 10.8 too and it won't run the last versions of both iPhoto and Aperture. It does work with earlier versions (Aperture 3.2.2 and iPhoto 9.2.3).
I suggest you to downgrade iPhoto rather than the OS as in less than one week Mac OS 10.8 will be released and hopefully you will be able to update it and to run the last version of iPhoto with it.
By the way, I think that my grandmother upgraded to this new OS but I don't know how to downgrade it.. LOL

Bluetooth does not work correctly with Siemens Tek Connect headphone device

I hopefully tried the new bluetooth support in OS 3.0, but it does not work with my Siemens Tek Connect headphone device. It syncs as expected, but no sound is heard. I can choose the Tek Connect in the music app and other programs, my headphone (actually my two hearing aids, which are connected wireless with ear to ear communications (e2e) via the Tek Connect necklace device) signals the connection to me (a beep), but nothing is heard. Codec problem?
Andreas

I own Phonak hearing aids with their Bluetooth-capable iCom device which allows my aids to be used as a phone headset and also supports the A2DP stereo bluetooth profile. My iPod Touch 2Gen 32GB is able to play to my hearing aids properly.
One thing I noticed is that the iPod does not allow you to control the volume when using Bluetooth. It expects the headphones to be able to control the volume. Have you used your hearing aids as Bluetooth headphones on any other device? Maybe the device isn't programmed properly to set the volume while in headphones mode. I know my audiologist had to program the volume on each mode separately on my device.
My MacBook Pro is able to play music over Bluetooth to my hearing aids fine. But I have never gotten Windows to work properly sending audio to my hearing aids. Do you have a Mac with Bluetooth? Try to get that working to see if it's your hearing aid device that's causing the trouble or not.

MacBook beeps 3 times and does not start up with upgraded RAM....

I recently started upgrading my macbook as i use large programs like final cut, after effects, and logic. So far ive installed an SSD (using OWC data doubler) and replaced the battery.
Now i'm trying to upgrade my 4gb RAM to 8gb but my macbook doesnt seem to be compatible? Im trying to use Corsair 2 x 204-pin SODIMM DDR3 1066MHz CL7 but im not having the best luck. Its the Mid 2009 13 inch Intel Core 2 Duo 2.26ghz model currently running dual 2gb 1066MHz which SHOULD be compatable but i get nothing except 3 beeps everytime i try to power on. As soon as i put the original RAM back in it works perfectly. Ive literally tried everything from trying dual 4gb 1333MHz, reseting my PRAM and SMC. No matter what I try it gives me the repeated 3 beeps! PLEASE HELP!

The correct RAM specifications for a mid 2009 13" MBP are: 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM. If you deviate from this you run the risk of the RAM not operating correctly.
I would suggest that you return the RAM and get chips with the afore mentioned specifications. Inserting higher speed RAM will not solve your problems. If it works, and it may, the MBP will down clock it to 1066 Hz any way.
Ciao.

IMac Slow Boot/Start up with firewire disk connected

I have recently purchased a a WD FreeAgent 1Tb external disk, to use as a Time Machine drive.
Since connecting this drive, the boot time has increased from less than a minute to nearly 5 mins.
I presume my iMac is doing some kind of check of this drive, and because its 1TB it is taking an age. Is there anyway to get my computer to ignore this disk on start up?
Is this a problem with Leopard? IS it resolved in snow leopard.
I have read some posts that suggest unplugging the drive on each start up, is this really what i have to do?, as its a bit of a pain.

It is not a general problem with Leopard. I have a 750GB drive that is used for Time Machine (via USB 2.0), a FireWire external drive, up to three iPods (FireWire and USB), and sometimes a smaller emergency/maintenance startup external drive connected during startup, and the startup time is not noticeably affected based on what is or is not connected.
Can you explain which part of the startup sequence is being delayed. Is the screen still grey? Has the Apple logo appeared with the spinning wheel? Has the screen turned blue? Is it that last part, when the Desktop is being assembled on the screen?
Have you reset PRAM?
http://support.apple.com/kb/HT1379
Have you run Disk Utility and used +Repair Disk Permissions+ on your startup volume recently.
Since the issue seems to be related to this 1TB drive, have you run Disk Utility and used +Repair Disk+ on that drive, to check for disk directory or disk data corruption errors? Time Machine does some complex file management, so such errors are quite possible, and that may be the cause of the delay during startup.

IMac sees the iPod but iPod does not start up. It had coffee spilled on it

My iPod had coffee spilled on it and it was not discovered for a bit. I dried it in rice and now the iMac sees it but it will not turn on. I did try to turn it on when I found it and I know now that I should not have. What parts may be bad in it now? should I try replacing anything in it or what? any advice is appreceated

Hey mjrussell,
When liquid comes to liquid being spilled on a iPod, you never know how bad it will be. Your best bet if you want to get it fixed is to set it for serviced through Apple. Take a look at the articles below for more information. The second article will also have pricing for your iPod nano.

ITunes does not start automatically when iPod is connected

iTunes used to start automatically when I connected iTunes. It no longer does. Can I fix that?
Dave

Connect your iPod and open iTunes. Towards the bottom of the iPod screen, there are four check boxes. The top one says "Open iTunes when iPod is connected." Check that box and click apply. If it is checked, uncheck it and click apply, eject and reconnect your iPod, then recheck it and click apply.
