Power Mac G5 :: Dual 1.8 Not Booting When Pressing The Power Button

Dec 13, 2007

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.

OS X :: Macbook Pro Freezes With Msg Restart Computer By Pressing Power Button

Apr 8, 2009

I have a macbook pro, bought it May last year(2008). I don't know much about computers, but I loved the transition between pc and mac, had no trouble with it, loved to work with it, until now. I had noticed it became slower like 3 weeks ago, and a week ago, it started to freeze up on me followed by a message that said please restart your computer by pressing the power button and the screen becomes dark. When I try to restart it again, it takes a while because it shuts down again and again, until the 10th time it works. The store told me to clean intall, which I did yesterday, it seemed to have worked, it was faster for sure, but today it happened again, 3 times! Has this happened to anyone? Does somebody know what to do?

OS X :: How To Boot Up From Disc - Pressing C While Starting Up Doesn't Work

Jan 14, 2011

I was trying to boot up from my Snow Leopard disc last night to run Disk Utility (to repair my hard drive). I pressed C while starting up but it took me right to my login screen. I did this several times, no luck. I'm using a 15" MBP btw.

I also tried the same thing on my sister's MacBook (using her own install disc) -- same thing, straight to login screen.

I know pressing C used to work before because the MacBook used to belong to me and I did an erase & install before passing it down to my sister.

Was trying to install Windows XP through BootCamp. The installation did not go through, and I quit it. After I tried to restart the computer however, it kept going to a black screen with a blinking _ on top.

I restarted, pressing the "option" key and the only partition that shows up there is one for Windows. I can't see one labeled "Mac" or something like it anywhere. I tried using the Repair Disk Utility but it won't actually give me the option to repair ir.

Sep 4, 2010

I've read that Early 2008 model MacBook Pros can boot into the Hardware test while pressing the D key on the keyboard without the disc in the drive (or was it the F2 key). I've also read that lots of people succeed doing it. Why does my MBP not do that?

Power Mac :: Switch The Startup Disk On G3?

Mar 17, 2012

I recently developed a problem where my Blue and White G3 Power Mac will not start in OSX. It starts but then displays a screen that tells in four languages to restart my machine. When I restart I just get the same message.This all started when I switched from booting in OS 9 to OSX.  Both had worked in the past.  Now I cannot return to OS 9.  Is there a short cut of keys to press to bring up the start up disk control panel during start up to try switching back to OS 9?

Mac Pro :: ATI HD 2600 XT Hdmi Signal Loss To LCD TV After Input Switch Or Power Off

Mar 3, 2008

Hook up a $3K machine to a $1.5K display and have to hard power down your $3K machine to get the picture back.When I boot everything is fine. If I change input to TV or power off the display, when I power back up or switch back to hdmi input screen displays error, can't read signal check output device. I have read on this forum about a issue similar with ATV but not with MacPro. In my google searches I read some issues with Vista, but no resolution... thought to be a ATI driver problem. Does anyone know of a tweak to fix the ATI 2600 XT to remember the tv signal after you change inputs or power off the display?

MacBook Pro :: Switch To Another Available Wireless Network And Then Switch Back?

If I select from the menu bar another available wireless network (one without a password for example) and then switch back to my own wi-fi network, am I still safe?

Did the fact that I connected to another network present any risks?

I did not send any private info during that time, any risks of getting hacked?

OS X :: Installing Tiger Over Leopard / Freezes - Hard Reboot From Power Switch

Oct 31, 2010

I have a 17" iMac G4 that I was rung Tiger with, then I installed Leopard 10.5. I use this as a second computer. All is fine except that my Epson scanner does not work with 10.5. I've tried the latest drivers. I'd like to reinstall Tiger. I used the 10.5 disc to reformat the drive and start from square one. When I boot from my original Tiger disc it starts opening it's windows, but when I get to the point where I can choose Install or use Disk Utility to reformat from the Tiger disc, all windows freeze and I need to hard reboot from the power switch. Am I correct to assume that 10.5 won't let 10.4 to reinstall. Is this correct?

MacBook :: New 60W MagSafe Power Adapter Doesn't Work?

Oct 10, 2010

I recently bought a new charger called the 60W MagSafe Power Adapter, for some reason for the first time when I plug it into my Leopard Macbook, it works. But when I take it out and plug it back in, it doesn't seem to charge. I would have to remove my battery and place it in again for the charger to charge my macbook. I don't think the charger is the problem because it charges on my macbook Tiger fine.

Hardware :: Macbook Suddenly Shuts Off And Doesn't Power On Again

Mar 2, 2008

I've had my macbook for about 15 months. i noticed a while ago it had trouble turning off completely when running only on the battery. then a few weeks ago it shut itself off and wouldn't start up again. the power cord indicator was orange, but nothing worked. ordered a new battery, that didn't help. tried a different power cord - nada. i took it in to an apple repair shop and they said something about the internal power connector (i'm not a techy) and took 2 weeks to repair. i've had it back 3 weeks now and the same thing has happened. only this time there is no indicator light on any of the power adapters. and my partially charged batteries do not work on their own either.

any ideas? i don't want to keep fixing the same thing and every few weeks it keeps breaking again. i mean, what's the point in having the computer then, right??

OS X :: Unable To Switch Between Apps / System Not Shuting Down

Sep 20, 2010

I had FCP open and I was 'log and transferring' a bunch of footage from P2 cards to my RAID. While that was busy working I was surfing the web in FF and listening to tunes via itunes. I had itunes mini player open. I wanted to see more info about a song and tried hitting the green button to maximize. Nothing happened. So I try command+tab but I get a 'bonk' sound and I don't switch apps. I though it was odd that even when I clicked on itunes the menu bar still said firefox.

Next I did the good 'ol command+option+esc to see if itunes was 'not responding'. this is what I see: Odd... no apps appear here even though I had 3 open not including Finder. So I go to my dock and click on finder and I get this dialog box:

So I tried going up to the Apple icon and chose shutdown. I clicked OK and waited and the machine never shut down. I had to to a hard shutdown. Upon restarting all is right with the world again. It's just weird that I have never run into anything like this in all this time and this new machine as been working perfectly since the day I got it.

MacBook Pro :: Screen Goes Completely Dark On Pressing C

Aug 7, 2010

It's only an 8 month old mid 2009 uMBP (2.26ghz, 4GB, 500GB). I was using the Disk Utility when it asked me to insert my MAC OS X Install disc and press "c" during start up and repair it. Every time I insert the disc and press "c" my screen goes completely dark. I thought it could have been a problem with the sensor so I flashed a light into it but it didn't work. I even tried putting it directly towards the sun light and still it doesn't work.

MacBook :: Unable To Charge Battery / Computer Doesn't Recorgnize The Charger

Jun 14, 2008

I have had my MacBook (aluminum) for 6 days, and all of a sudden i go to plug it in to charge (10% left) and the led on the magsafe doesn't come on and the computer doesn't recorgnize the charger (even in system profiler).

upon closer inspection i noticed the LED is on on the magsafe, it is just a very faint shade of green.I have tried a charger from a different MacBook but no luck. And i have also tried my charger and a different macbook and it charged it just fine.. so it's probably not my charger.

Any ideas?? i know i can go get it replaced.. but i would really like to not have to take a 45 minute drive to the apple store if i can avoid it.. (unless this problem is serious and should be replaced) also, if i get a replacement is it possible for them to just swap my HDD with the new one?

Sometimes restarting is not enough: you need to power off your Mac, wait for a little, and power it on again.It could be a script which act like the "schedule" program in system preferences: it would switch off the Mac immediately, the add 1 minute to the current time and switch it on again.

MacBook :: Escape Key Dinging - Requires Pressing Command Key To Reset?

Feb 14, 2009

I am new to my unibody Macbook. I bought it as an open box item at Best Buy. I was desperate for a new computer and I had and still have little cash. Therefore, I am hoping someone has an easy fix for my odd issue. It seemed to be fine for two or three weeks and making my life so much more fun, now it works but is annoying.

Now that I can't return the machine, it is making the "bonk" noise in succession as if I am repeatedly pushing the escape key with no window open. Other times it will not let me click the mouse when this happens and if I press the apple key it seems to be fine, almost as if it resets an works like there is no problem. I can't find any pattern to when this happens it seems completely at random.

There is no odd esoteric software on my computer and I haven't added any weird downloads on it either. I just have been importing music and photos so far. I haven't had it long enough to get it too screwed up.

I did reinstall Leopard trying to clean out anything that may have been causing this. It didn't help. I downloaded a patch from apple to fix an issue early unibody models had with the track pad. This didn't help anything either. I am almost wondering if there is a glitch in my escape key. I don't have apple care, at least I don't think I do, as I didn't pay for any extra warranty.

Power Mac :: G5 Doesn't Boot To New Image?

Mar 8, 2012

I'm attempting to install several PowerMac G5s with the same image.  All the PowerMacs are the same vintage, and two of the four seem to work just fine.  The other two have the same issue. 

I created a model machine that's suitable for cloning: installed and updated all necessary software, configured system settings, and then used Disk utility to copy the model system to a read-only disk image.  I then used the Disk Utility application to prepare the system image for deployment by Scanning the Image for Restore. 

I then restored the image to hard drives with Disk Utility.  I placed in the four HDs in the PowerMacs.  Two of the PowerMacs booted without a problem, the other two won't boot to the restored image.  I tried holding down Option key when booting, and option to boot to the drive never shows up.  Also tried resetting the PRAM, but that didn't work either.
