i got me a built up powermac g5 with a 1.6 ghz processor. i got it on the cheap, so i took it and built it up as far as i could afford (4 gb ram and a 500gb hd). lately ive been noticing that NOTHING is compatible with the powerpc processor. im looking at new motherboards to put in it, but im not sure where to start? i was thinking about the Intel DX58SO then putting a dual core intel 3.16 processor into it. can anyone tell me if theyve done this and its worked for them? id love an intel power mac
I'm using a B&W Power Mac G3 with 512MB RAM and OS X Tiger for a SMB file server (with 5 users) and a USB printer server. Everything is working good, but I have a problem.
It doesn't have a monitor or keyboard/mouse attached normally (I can configure it via VNC). The problem is that I would like to be able to turn the machine off when it's not needed (like at night sometimes, days when I won't be home, etc.). I would like to just hit the power button and have it turn off, however it puts it to sleep instead.
Normally, sleep would be fine, except on the B&W, the fans still run, just the HDs shut off, so it's still noisy as heck.
Is there a way to make the power button shut it off? If not, any other easy methods of shutting it off you can think of? Via VNC won't cut it, as my dad needs to be able to turn it on (not a problem) or off as well.
I'm running an 8-core 3.2GHz Mac Pro and I'm wondering why Quicktime Pro is only using 30% to 40% of my system's overall CPU power (when I encode video).
Is this just the maximum speed of QT? Is there any way to increase the CPU usage?
I have an early 05 PowerMac Dual 2.3 machine that's making some intermittent clicking noises over the last few months. There's no pattern - sometimes it happens every few minutes, sometimes it won't happen for hours. The clicking sound is loud - and is accompanied by, what I can only describe as, a bit of a buzz sound. At first I thought it could be my HDD or superdrive, but I think the click is way too loud. Now the question - is this my power supply getting ready to give? The machine does not fall in the range of the power supply repair program. I'm already in the process of adding a second HDD to clone my main drive just in case.
This is in reference to a Mac Pro 3,1 8-core purchased around Feb 2008.
Lately, I've noticed a strange noise coming from my power supply that sounds like the noise a refrigerator radiator makes. It's a humming noise that rapidly comes and goes, constantly.
The power supply fan speed was running at 599rpm yesterday, but is running at 629rpm today.
I'm not sure if the problem could've been caused by adding additional ram (12GB, OWC) or an additional HDD (3rd HDD, WD), but I didn't really notice the noise until after adding these components.
What could be the cause of this problem? What are my repair options if necessary (without Apple Care)?
I was out of town so this description was second hand but the computer has been running a little weird for a while. When I have too many apps open or on a website that has a lot going on...the computer starts revving up until I quit out of everything and let it slow down. I guess while I was gone, this happened but nobody quit out the apps and it eventually turned the screen black. When I tried restarting it sounds like the computer is working but the screen is black so I can't see if it is booting up or not. I took the monitor into the apple store yesterday and it started up right away for them. It's a cinema 23" I think.
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)
my old 2x2Ghz PM G5 (late2004) doesn't launch the boot sequence:
- when pushing power button, the blue led turn ON as long as I keep it pushed. If not pushed, it light off but yet the fan are running.
- no chime
- the fans turn on normally and the hard drive start a little to make noise once powered up.
- no video on display, the screen is black.
- the keyboard is not recognized anywhere I plug it. Â
- after a minute or two of non activity, the fans start to blow full speed (guess its a security measure for saving processor)Â
I ve done the reset of PMU several time (unplug the power cord then push the button at bottom of mother board)As i dont have access to keyboard, I can't start on Target mode to check if the HD is failing all.I ve removed all RAM extensions and left only one pair in slot 1 (J0), and changed the pair to avoid a faulty RAM.I only have a redlight on motherboard if I don t put back the glass panel.I ve check the voltage of the lithium battery, and yet its the original, the voltmeter says its 3,6V...Â
I've bought my iMac in December 2011 and everything was functionating just fine untill 1 month ago. My iMac started to make clicking sounds for around 5-10 seconds, the interval between these sounds is usually half an hour to one hour. I personally think that it comes from the right side (the one with the CD/DVD entrance). I'd like to know what it causing this, how I can get this fixed and if it could be harmful to my iMac. I'll contact some premium resellers tomorrow and ask if they know what I can do about it. Â
Since about the 3rd day after I got my macbook pro the computer has been making cracking sounds when I open it. When it first started it just simply made one clicking sound when the hinge is halfway open. Now however, When it is open it makes cracking sounds that don't stop ( open 15 cracking sounds per open). Is this a serious issue that I need to address with my local (and very mean) genius or is this issue not going to continue to get progressively worse. If this does continue to get worse will the hinge crack open? what is this worst that could happen?
My iMac (27'', mid 2010, Core i7, OSX 10.7.4) recently makes some trouble with its DVD drive: The drive often makes horrible noises like a shredder. In this context the disc sometimes doesn't eject. Only Rebooting works. More and more frequently the drive hangs, the connected application (e.g. iTunes, Auditri or Handbrake) hangs and also Disk Utility. Rebooting doesn't work (white freezing screen), only shutdown and complete startup with clicked Trackpad to remove disc. Is it a hardware or software error? The iMac is still qualified for AppleCare. Should I make a repair request to Apple?
When I launch Mail app, my mac starts running ridiculously slow. I get the spinning ball after almost every click.Just switching between safari tabs can take 1/2 minutes. In activity monitor it is showing 118% is being used by mail when it is running which hogs the entire CPU effectively.When I quit the application through activity monitor it quits, however if I try to quit (CMD Q) or force quit the application nothing happens. Also when I try and shut mail stops the shut down.Â
I purchased a 21" iMac a couple of months ago. Today it started making constant buzzing/humming noise. It's not really loud, but it is noticeable and annoying after a while. It stops if I put the computer in sleep mode or turn it off, but it starts back up the moment I turn it back on again. It sounds like it is coming from the bottom of the screen near the speakers. I have tried adjusting the brightness and volume, but to no avail. I also tried lifting the computer off the desk to see if it was just vibration, but that did not make a difference either.
last night I was using my computer just chatting with people, then all of the sudden it shuts off. Now it won't boot past the apple grey loading screen, and the fans slowly rev up till they are full boar, and I have to shut it off for them to stop. Â I've reset the PRAM, the SMU/PMU, tried holding alt and selecting my drive to boot to. None of these did anything, and didn't help at all. Â
I've heard it's a processer or logic board failure, or a HD failure, or something else. I'm ready to buy a new computer, I'm actually kind of sick of this one, I just want to know if I can fix it or not. I will probably take it to the apple store just to make sure, but maybe I can get an answer on here to know how to fix it or just to know that it's dead.Â
My computer shows an upward facing arrow and makes a clicking noise when i hit the shift button, if i hold it down it switches into caps lock ... how can i get out of this mode?
My 20.5 inch 2.7GHz iMac is about a year old and has recently started making a low humming/buzzing noise from the top right corner, near the SuperDrive bay. The top of hte iMac feels quite warm when it makes the noise and usually stops if I hold my hand on top of the computer. Is this something I should be contacting AppleCare about?

I am trying to make a card and we don't like the color palate in the background. I would like a template for just the card (basically just the fold in the paper) so I can make my own background color palate.Â

A couple of nights ago I realized my five year old iMac was making a sound I have never heard it make before. It is a scratching noise that I assume is coming from my internal hard drive (hard drive is stock, has never been replaced). It isn't a super loud noise, but it sounds like the noise some hard drives make when they are "searching" or "thinking". I'm wondering if my hard drive is beginning to fail, or if the problem could be something as simple as dust or dirt caught in the drive. An audio sample is in the link below, [URL]
Before making a slideshow in iDVD the pics were sharp (& in preview), but after burning the show to disc the pics had become fuzzy. How do I keep this from happening?
my 4 year old IMac 2.4ghz intel core 2 duo with 2gb running 10.7.3 has been running really slow since I installed photoshop CS4 and upgraded to lion ( I have 137gb of free space on hard drive) I mean it wont quit out of photoshop I always have to do a force quit and most applications run really slow. Do I need a new computer , what should I go for to have a smooth running mac?Was thinking of a new IMac 27-inch: 2.7GHz with 4gb memory.Â
I bought my imac 5 months ago. I was browsing netflix today and the phone rang, went to answer, came back about 20 minutes later and I thought my imac had gone to sleep. tried to click my mouse to wake it up but it wouldn't do anything. I tried the power button to reboot, still nothing. Plugged it into a couple different outlets, still nothing.
My mid-2007 intel iMac 24" won't power on, there is no sound, screen activity or signs of life other than a slight "bzz bzz" when the power button is pressed. Yesterday it was working fine, I put the computer to sleep and when I attempted to wake it the next day, it would not. The optical eye on the mouse was lit and a green led light could be seen reflecting through the memory access door, but the computer made no sounds and would not wake. I held the power button until the mouse turned off and then attempted to reboot. All I get is a quick buzz (possibly the hard drive sound that you normally hear just before the chimes and screen powering on) when the power button is pressed, but no other activity. I attempted resetting the SMC and reinstalling the memory, no avail. Just a little buzz and nothing else. An
