Lately, whenever I start it up in the morning, I will almost immediately get a shutdown prompt ("Are you sure you want to shut down your computer now" ...). Nothing on the desk is touching the power button. Whenever I click "cancel", the prompt pops back up within a few seconds. If I hit shutdown or restart, it will just startup again with the same problem. Putting it to sleep doesn't work either, because as soon as it dozes off, another prompt pops up to wake it back up.Â
My company's IT guy thinks it is a power supply issue. He suggested that I unplug the cord from the machine and let it sit for 20-30 minutes (thinking it was building up too much of a residual charge or something like that). This actually worked for a period and still works most days, albeit not very reliably.
One intersting side note is that this problem only seems to occur in the morning. After, I've messed with the power cord and rebooted a couple of times, the machine seems to just get over the issue and I can work normally for much of the day. I'd to think I have a serious powersupply issue that might cause a crash.
I started to have problems with a used PowerMac G5 that I bought on December last year. The computer came with dual G5 at 2.0GHz, 8GB and 160GB Sata hard drive. The computer was running Leopard 10.5.8.
Once in my home I erase completely the hard drive and installed Leopard from scratch and ran software updates. At this point the computer was functioning good, sometimes crashes when I tryed to import images on iPhoto or Aperture, but appart from this nothing more. Few weeks ago I installed a new hard drive, the disk it's ok and doesn't give problems. The problems started two weeks ago, when computer crashes constantly and at any time with any reason, kernel crashes reports sometimes reports for Safari, other times for iTunes, others for uTorren, mdworker and mostly by Unknow application. I must to restart the computer by force shutdown, that only put thing worse. I was looking for documentation about solve my problem, but there is not so much responses.
Ive got a 2008 Mac Pro and recently Ive been experiencing some issues with its USB ports. The front usb ports have a USB antenna connected and some time later, it just loses power and I have to disconnect it and connect it in order to make it work again. Besides that, Ive got a USB hub connected in one of the back ports. In it, is my camera and my keyboard. After some time, it just loses power. Not at the same time than the usb antenna, but in less that an hour I have to repeat the process 2-3 times. Worth to note, that in the two back usb ports left, Ive got an external hard drive in each and I dont have problems, there are always seen in the finder.
I've had my G5 for a couple years. I keep it under my desk, so I don't hear much from it, but I have noticed that the hard drive is constantly spinning. It's been doing it for as long as I can remember. Any ideas why, and whether I should expect a failure because of it?
My pm g5 it just shutdown by it self I try to leave it unplug all day and it work ok but the in the middle of any work it die on me i put a new battery it did not work push the pram bottom same thing.
I have a Macbook from the beginning of 2008. Last July. I started to have problems with the battery , it was not recognized. It had an X icon and the power lead was green all the time. I took the computer to an Apple outlet and they told me that the battery was finish and I needed to buy a new battery, I bought a new battery and still the computer didnt recognize the battery, apparently the battery was not good. Apple changed the battery and now, I have a 3 battery. Now the battery is charging but on and off. Last week the battery was working fine for 4 days, but after 4 days the battery was not recognized, x icon again and lead green all the time.
24 hours later started to work fine. Today as I write this, the battery is on and off, two minutes is charging, 5 minutes is not recognized, and so on. I tried to reset the PRAM, System Management, etc but still the same thing, I even deleted ITunes, as the first time I started to have problems it was after downloading a new Itunes update and last week the battery was working fine for 4 days and crashed just after I started to charge my Ipod. Maybe it isn't related at all but I don't know. Could it be the logic board? the thing is I took the computer to Apple for a diagnosis but they told me that they didn't have a clue what it could be.
I have had this problem for the last year but have worked around it by manually shutting down the system. My mac will not shutdown on command or restart during a program update or by going to the apple and trying g to restart. I have tried on numerous attempts to find a related topic but there is none to my knowledge.

Today I started to watch a video from a news site (probably using flash) and the computer started to slow down very much so I thought firefox had crashed. Then I force quit it and waited about a minute or two hoping the computer would get fast again as usual but it did'nt happen, so I tried to log out and nothing happened and then I tried to shut it down by clicking the power button and clicking in shut down.
Right after that, the computer started to shut down or log off (it was still very slow) and something happened it stopped in the middle of the process and displayed a blue screen (the same colour that appears when you connect another monitor to the mac). Then I thought of using my last resource: holding down the power button until the computer turned off but again, nothing happened.
Has anyone had the following problem? My Macbook Pro is 2.5 years old and has recently been shutting down for no apparent reason while plugged and unplugged into the power adapter. I went to the Apple store a few weeks ago for an issue where the Macbook Pro would not turn back on at all. They had to replace the logic board. But after that, I now have the problem of the shutdowns. I went to the Apple store and got a new power adapter because mine was broken. I thought that would be the problem, but it isn't. I also recently reinstalled my operating system and the problem is still occurring. Does anyone have any advice? My laptop is a 2.2 GHz Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM. My battery is in 'poor' condition, but according to the Apple experts, the battery has nothing to do with this issue.
encounter kernal force shutdown when I power on my laptop. happen agin 2 times Is there any way I could contact Apple helpdesk though email in singapore?Lost , only phone number on the website no email support.
I need to use hdiutil create command line to create DMG within a script. A popup asks me to enter my password. I would like to skip this step which breaks the execution of the script and automation of the DMG generation. How to skip the password prompting or pre-enter my password so that the script can execute without any action from any user.
I have the latest version of Safari (5.0.2) on Snow Leopard 10.6.4. I'm also using 1Password (3.4.4). I'm encountering two issues: 1) Safari rarely Autofills user/passwords when surfing. Autofill is checked off for "User names and passwords". 2) I keep getting prompted over and over again to save my login information in Safari. I continue to click "Yes" but neither Autofill remembers the information and I get prompted again the next time I login.
I'm not able to connect to my network, and I'm stock. I'm not a MAC user generally. So I'll try to explain to you briefly what I've been trying to do. No command line stuff! Switching my computer on shows me that I have 3 networks available, I tried to connect to the one I want, it prompted me for the username and password, and kept the authentication option as Auto. Clicking enter doesn't do anything! It should have prompted up for the certificate to install. I checked to see if I have the certificate previously installed using the keychain utility and there wasn't anything there. I even deleted the login key, but its still showing an error in Safari "you are not connected to the internet".
i have just purchased a MacBook Pro off a friend and so it has recently been restored to factory settings and upgraded to yosemite. I use eBay a lot but have discovered there is no app for eBay. Then i found out you can get notifications from Safari. I know eBay is one of the websites the websites supported but the prompt pop-up isn't appearing when I'm on the website. I'm logged in too.Â
I just set up my Airport Extreme, which is connected to my modem, and created a new network. The problem is that when I connect my MBP to my new network, it doesn't prompt for the password which I have set to WPA2. I'm not sure if it's the cause, but I called my ISP about my Airport Extreme previously finding an invalid IP address and just overall not working. He told me that it's strangely acting like a hub instead of a router which he said is not secure. I'm not really sure what he meant but he doesn't seem to know how to fix it. I can connect to the internet but the problem is that there is absolutely not security and perhaps that's the cause of the airport acting weird?
I'm experiencing some issue when I tried to reinstall my OS. It just keeps prompting me Mac OS X cannot be installed on this computer. You have to use your Time Machine to restore..... etc. But its a brand new hard disk. I have also tried using another hard disk. Its just keep prompting the same error.I also have deleted and recreate with 2 partitions, but problem still surface. Deleted and Erase at Utilities- Disk Utility, also can't help.
when occurs a suspension of hard drive activity, manually or after a period of inactivity, this suspension seems to be incomplete (a ventilator continue to run) therefore my mac (power-mac G5, OS 10.4.11) is unable to restart, no possible action from the keyboard (I must shut down and restart)

My iMac 27 late 2010 does not shut down when shut down in the normal way. I have to shut down with the push button. I have tried disconnecting all the usb connected hardware still no use. Can any body help.I have OS Lion 10.7.3?
My 13" MacBook Air Mid-2011 Version currently running Mac OS X 10.7.3. Is constantly overheating and the fan is constantly loud. The fan is around 5500rpm even when I am not doing anything on it or even when it is off.
My system has randomly shut down twice now in the last two days. Dual G5 2.3. I checked the console log, which I know very little about, and it said this:
localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122
Two questions-
what's the -122 code mean?
Do you think resetting the PMU would be the solution to this?
My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.
I have a iBook G4 laptop and there seems to be something very wrong with it. It started a few days ago just randomly. I was reading something on the internet and the screen went black on me, but the power was still on (I clicked CAPS LOCK to see if there was power). I then proceeded to push the power button and the power went off. When I pressed the power button again to turn it on, it made that internal noise it always makes and then the fan came on, and wouldn't turn off. There was no picture on the screen at all. Completely dead. But there was power, because when I clicked on the CAPS LOCK, the light came on). I tried pressing on the power button for at least 15 seconds and even went as long as a minute, and the power didn't go off.
I had a bad power surge (USB hub that was plugged into the back of the display had the wrong power cord plugged in... very stupid mistake I know!!) take out my 23" Cinema Display. The display shows no sign of life (no power light, etc) and the brick has been tested and is OK. My local service place says that they will have to send the display back to Apple which means a minimum of $400 for repair so I'm wondering if anyone has had a similar issue that they resolved successfully? The service place suggested that Apple would replace the logic board but is there any way to test to see if this is the main issue? I have seen logic boards sold separately online but would be hesitant to buy it without know that this would fix this issue.
I made this a new topic because I think it is important enough to do so. Probably most of those that originally complained about this have moved on to the new MacPro but I am sure there are still enough G5 owners out there that still have concerns about this topic.
A clean install of Leopard eliminates the infamous power supply beeping
Its amazing, my G5 is like a new machine; no more of the annoying power supply beep; although, I learned to live with it after a while and didn't even notice it. However, the silence is now very noticeable.
I have found that by plugging in my Apogee Duet firewire audio interface and ONLY WHEN AppleFWAudio was loaded there was a 10c CPU raise that was making my MBP (late 2008) hot!I wanted to monitor the power that was required for Duet to run and to see if the temperature rise was due to that, so:With Apogee drivers uninstalled (just to be sure its not their drivers related, which is notMBP on battery power with System Profiler opened (to monitor the mA required by the computer from System Profiler -> Power)
a friend recently gave me a g5 power mac that had some issues, and the failure was described as intermittant. The machine supposedly would work properly when booted and start freezing up after time, but if turned on the next day it would work properly for some time. I assumed it was an overheating issue, but apperently there is more to the picture. I have tried booting the machine quite a few times and the display always reads no signal. The machine sounds as if it were booting normally, but there is not output. At first I assumed it was my display cable, which was a DVI-D single link, however the DVI-D dual link cable leads to the same result. Is it nessicary to have a DVI-I cable? None of the error LEDs light up on the motherboard. After doing some hunting I haven't found anyone with the same issue, but I am wondering if I should assume the graphics card is dead. What steps do I need to take to isolate a graphics card failure in a power mac g5?
I hav" a "late 2004" G5 2.0 dual processor. To upgrade graphics card, I find many require a power supply splitter. Do I have a molex 4-pin connector? I can't see the location inside the box.
