I got my 2009 2.66Ghz Quad Mac Pro with the ATI4870 graphics card a few weeks ago. I noticed that when the machine is off, but connected to an ungrounded (or shared with other devices) electric outlet, the whole case gets electrified and power leaks to it. If one's touching it the machine and making direct contact with the floor, it gives small-pulsing-continuous electric shocks.
View 9 RepliesI have recently realized that the top corner of my screen have more light than the rest of my screen, and I'm wondering whether that is something normal? and everyone is experiencing the same? because I have compared it to my friends Unibody Macbook ( late 2008 ) and it didn't have this type of light on the top. That's just shown when you look at the screen from a higher angel ( from the top ) and while the surrounding atmosphere is dark.
The pictures below shows exactly what I'm talking about.[URL]
I've got a Mac mini (2, 1) 2 GHz, 2 GB of RAM. I installed this prefpane:
/Developer/Extras/PreferencePanes/ to get a look at what is going on, like in Activity Monitor in Windows.
I opened up the Processor Palette and did some basic tasks like going over the Dock, opening Dashboard, etc and found that, at time, those basic tasks used 50% of my processing power! Also the Time Machine GUI used 90%
How can I reclaim some of this power?

View 4 Replies View RelatedI consistently find that when using Safari (or Firefox), within a short period of time (sometimes even less than one hour), the browser has taken over nearly all available memory. This happens even when the browser is the only program in use, and when no webpages with extensive audio or video content are open.
Can someone explain to me why this happens -- i.e., why web browsers seem to hog all the memory they can find -- and (more importantly) whether I can take steps to prevent it from happening?
As an example, my current System Memory readings (from Activity Monitor), with only 'Firefox' and 'Activity Monitor' open, are: Free memory 74.9 MB (but frequently dropping to less than 10 MB) Wired 228.4 MB Active 1.20 GB Inactive. 504.5 MB Used 1.92 GB VM size 31.99 GB Page ins. 292.1 MB Page outs 120.6 MB Swap used 518.7 MB

I'm running SL, haven't rebooted in several days.
I have no desktop applications running.
I'm on a MBP 13" w 4GB RAM.
Activity monitor is reporting 2.21GB memory active, 908.5MB wired. 106MB free.
Most unusual, is that I do not see any application in Activity Monitor using much real memory, yet it reports 2.21 GB memory active. I have had as much as 1.4GB swap space used, with no obvious culprit.
Any idea where the memory is going?
I usually don't complain about stuff but I noticed last night on my MBP (one below) that I have some light leakage on the left and right side of the panel. When I have a dark wallpaper you can defiantly notice it.

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.
View 10 Replies View RelatedI 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.

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.

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.

View 5 Replies View Relateda 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 have the problem that I need to frequently power cycle (shut off and on) my dsl modem to maintain a reasonable speed with my internet connection. It is making the internet experience pretty user unfriendly. Does any one know whether there is a way to optimize my internet connection such that this is not required so frequently (couple times a day)? I am on my second dsl modem, and the same problem has occurred with each of them. ATT simply advises me that my solution is to power cycle the modem to sync the system, whatever that means.

I added 2 sticks of 512 to my power mac g5 1.6. I had ahard time getting the computer to see the new ram, but finally was able to kinda get it working after zapping the pram. However my computer only saw these 2 sticks as 256, odd. So i attempted to troubleshoot the problem. I tried just installing the new ram, but the computer wouldnt boot. I tried a few different combos with the other 4 sticks i had, but nothing. I put the old memory back in, and still nothing. The power led looks to blink once every five seconds or so. I tried pressing the pmu reset button, but still the same out come. I also tried taking out the battery, nothing.

I had a weird issue this morning. I started computer and it did not make the chime sound, it didn't do anything at all. I disconnected it from the extension cord as well as all the peripherals attached to it and nothing. I tried a different start up disk and again there wasn't a sound. Then i unplugged it and reset the SMU on the mother board and air sprayed the computer to remove all dust. Then plugged it back and it came back on.

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 just got my new imac 2 days ago. I was wondering is there another to turn on the power without pressing the power from button? (cuz i remember u can power on from the keyboard b4)

Is this normal? I'm pretty sure it's not, at least the iTunes bit. I am using cover flo and I know that's supposed to increase the RAM usage but I don't even have the window open (it's in another space.) I've been seeing this high amount of RAM usage lately so I ran techtool deluxe and there was an error with the volume structure. I repaired permissions from the OS X install disk and since then the volume structure test passes but I'm still getting the unusually high numbers.
