Mac G5 late 2004 dual 2.5 won't boot.

hi, i have late 2004 G5 dual 2.5 ppc and it won't boot,chime or show any video the only thing i get out of it is the cpu fans spool to 100% after a few minutes of power on time and the air is warm, I have tried to power it with no ram to see if there are going to be multiple chimes for missing ram notifications but to no avail, the bott with option key pressed produces no post, can it be saved with in resonalbe cost or have any sugestions, Help.

Hello,
Cheapest thing to try first is...
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

Mac Pro Dual Quad Core won't boot OS/X, but plays fine with Linux/Windows

I've got a Mac Pro Dual Quad Core won't boot OS/X, but plays fine with Linux/Windows. I've tried all of the following initial tests as suggested on forums:
-Ram swaps
-Alternating video card in PCIe slots
-Trying alternate video card
-resetting pram and smc
-Multiple tests with memtest86+ over 26hrs and no failed ram
-Multiple tests (8-12 cycles) with apple HW diagnostics and no problems
-Firmware is approved firmware for early 2008 model...no new updates.
Gentoo livecd works fine and I even installed to hard drive and it boots fine with it. In addition to above tests I also ran a linux stress test putting all 8 cores at a load of 22 for 2.5hrs with no problems.
Memtest86+ for 24hrs+ yields no problems.
Where problems occur:
Booting off hard drive, DVD or firewire yields an immediate curtain of death and booting off a new snow leopard DVD dies about 25% into the install.
Looking at error log and a quick dmesg shows "Package 0 didn't get an HPET" and complains about AppleIntelCPUPowerManagement.kext. Google turns up illegal uses of this, so doesn't apply to my use case.
I'm a bit stumped since all was working well until one day it was non-stop curtains of death and can't get them to go away.
A logic board replacement at $1100 is not a feasible option for something that works on linux and windows, but not OS/X, is a bit disappointing and somewhat surprising.
Thanks for your help and advice.
Regards,
Marcos

Someone here once thought they knew EFI and Open Firmware a little, and used some commands from OF library that an Intel EFI Apple system didn't like. New logicboard.
Of course to run or boot OS X and see video you need EFI based card. The presence of some PC cards can block OS X from booting.
The fact you get part way through SL DVD, pull all the drives, put in a new drive and format it from SL DVD.
Most of the things you tried are what are more common with PC hardware. Including where people have tried and failed to install OS X on unsupported hardware.
I suppose it is possible something tried and failed to modify the Mac's firmware.
If you have Windows running, and you have WD drives, WD just posted new Lifeguard utility which is what I use to do a good job of stripping a drive down and recertify it for reuse, works wonders. Maybe same for other makes with vendor utility.

What kind of wireless card I need for my Power Mac G5 (late 2005) Dual 2 GH

hi there,
I have for sometime now a "Power Mac G5 (late 2005) Dual 2 GHz PowerPC G5", and recently I have been thinking to get an Airport extreme wireless card with a bluetooth on it, which could work on my machine.
I have already try to deal with apple representatives and Apple sales people to give me a hand on the matter and so far is been a nightmare to approach this guys, tired of wasting time and effort, so that is way I am posting a topic on this section to see if you guys could give a hand on the matter.
All what I would like to know is what kind of wireless card I need for my Power Mac G5 (late 2005) Dual 2 GHz PowerPC G5 (version 10.4.11) and where I could buy one on line to install myself.
This is the mac unit I have.
Dual 2 GHz PowerPC G5.
Hardware Overview:
Machine Name: Power Mac G5
Machine Model: PowerMac11,2
CPU Type: PowerPC G5 (1.1)
Number Of CPUs: 2
CPU Speed: 2 GHz
L2 Cache (per CPU): 1 MB
Memory: 4.5 GB
Bus Speed: 1 GHz
Boot ROM Version: 5.2.7f1
Thanks for you time.

Toyko koyko

You're welcome. Funny how Apple works isn't it? If it's any consolation, that Airport/Bluetooth card doesn't show up on the Apple U.S. store either. I don't think they ever intended it to be a user installable part, so perhaps that's why they don't offer it for sale. Do you have any Apple Authorized Service providers in your area? I'd think they'd be able to order the card as a replacement part.
Can you give a little more detail or a link to the gadget you're referring to? It sounds like a USB dongle to enable Wi-Fi, but that must be a third party solution, since I don't believe Apple ever offered something like that.

After Effects is NOT using the full Twelve GB of memory on my Mac Pro late 2013 dual video cards

I would like to know if there is a reason why AE CC12 and CC13 (2014) is not using the full amount of video card memory on my MP late 2013. It's six GB per freaking card I invested in and its not accessing it.
Is there a work around this issue?

Why shouldn't it. When I upgraded to this new Mac Pro late 2013 with its dual video cards. Premier turned into a blasting fast editor. I no longer need to render my edited cuts and the scrubbing of preview and timeline footage is phenomenal. The only performance boost I've seen in AE with this new system is in rendering and I can't even say its double as fast in comparison to Premier or Encoder and its an 8-Core system with 32GB of ram. Everything else is flying.
So again to answer your why should it. I rebuttal with "Why shouldn't it". The other two mentioned programs are using GPU resources to improve performance why is AE so behind the curve.
I'm not the only one asking why. I was in the audience at a Dmala meeting here in LA with Todd Kopriva and Al Mooney previewing AE and Premier 2014.
People kept asking Todd about performance boost in between questions about new features. Todd finally just asked what do you prefer a couple of new features or performance boost. Everyone wanted performance boost over new features. If you think I'm making this up go ask Todd Kopriva.

HT5918 Mac Pro (Late 2013) Dual monitors freeze on startup?

I've got 2 monitors, 1 HDMI and 1 MiniDisplayPort/DVI into Thunderbolt, and the computer can't start, it crashes during the boot process. The main screen freezes just as the login comes up, the MDP screen is scrambled, and the mouse cursor is a spinning pizza.
The only solution so far is to remove the MDP cable during startup, but that is a dealbreaker because dual monitors is the sole reason I bought this, and c'mon it's a really expensive computer -- even my old MacBook could handle 2 monitors!
Any insights or solutions appreciated.

Have you tried another cable and adapter?
Try another DVI monitor to help determine the cause
Are you using a Thunderbolt port not shared with the HDMI port?

Powermac G5 dual 2.5GHz won't boot

Hi,
I've recently started having issues with my dual 2.5GHz G5 Powermac. When I switch it on I can hear the drives start up and data being read from them. But there's never any chime and the screen stays black. The drives stay quiet (spinning but no data being read). After a minute or two the fans ramp up to full speed.
If I leave it off for a while (eg. overnight) it resolves itself somehow and boots up without any issues. Once it's booted up there are no issues at all and it will run fine for weeks and days, until it needs to be rebooted again. I just put it to sleep when I'm not using it and it wakes up fine.
I've tried the following without any success:
- unplugging all peripherals (usb + firewire etc)
- reseating the ram
- swapping out the ram
- trying to boot into open firmware (it won't get that far)
- resetting the pmu with the button on the motherboard
- installed the latest updates to os x
- reseated the graphics card
- replaced the battery on the motherboard with a brand new one
This started roundabout the time I upgraded to 10.5.5 though that could be a coincidence. I also cleaned dust from the inside of the machine at that time as well (including off the graphics card fan and heatsink which was getting clogged up). So, that may have caused it. But again it could just be a coincidence.
Does anyone have any suggestions? All fans and both fans spin up, so I don't think it's the PSU, but I could be wrong. My only thought at the moment is a possible problem with one of the drives. So, I could try installing to a firewire drive and booting from that, but given that I can't even get into openfirmare, I'm not confident in that working. Similarly I don't have much hope of it booting from CD.
Any suggestions or help would be very much appreciated

Hi Phil Brayshaw-
What does the little white power light do? This should be helpful: About the Power Mac G5 (Late 2005) diagnostic LEDs
Although it sounds to me like you have tried most of the troubleshooting steps, this document is a good overall reference to address this particular problem: Power Mac G5: What to do if you see black, white, or no video at start up
Have you tried another monitor and/or double-checked your cable and its connections? If everything else is working as expected that would certainly be a major suspect.

Dual 2.0GHZ won't boot, help?

I have a Power Mac G5 Dual 2GHZ, I believe the first late 2004 model. It had 3.5GB's of RAM and an older model Apple Cinema display.
The problem is, is it just wont boot up. I turn the power on, the screen remains blank and the light flashes on the computer 3 times. I consulted the manual and it says that if the light flashes 3 times, the RAM is incompatible. However I took out all 8 sticks of RAM and tried each pair for a boot, but none of the pairs would but and I received the same 3 flashes. I should also add I tried resetting the PMU and it didn't solve the issue. It doesn't boot so resetting the PRAM also is a no go.
Everything powers on properly, so I'm don't think its the PSU, unless you know different. I'm not sure if all my RAM has died, if its the Power Supply or Perhaps the logical board has failed? Or maybe something else?
Any help would be greatly appreciated, thanks.

Any idea what might be charged to have someone to replace motherboard?
I'm having the above problems starting shortly after I installed Leopard. The Mac is unusable now and in the shop. I became concerned though after the Apple authorized Tech guy gave my machine a 20 minute lookover and didn't have a clue. Talk of motherboards and power supplies came up. I know both are expensive not counting labor.
I bought a used 2.7 ghz. G5 this morning. Maybe it's premature but at least I get a better machine that will be working, here in a few days.
I'm out cash but I struggled for days trying to figure my Macs problems out. The nightmare is over. For now...

Mac noob has an imac g3 that won't boot

i recently got a imac g3 from a friend to play with. i've never used a mac, so i was hoping to learn a bit.
at first, it seemed to work fine... nothing wrong
later, out of curiosity, i tried to boot from an ubuntu live cd and that's where everything went wrong.
it started to boot, then hung, so i ejected the CD and rebooted the computer... and ever since, the computer won't boot at all
it makes the chime, then sits at a grey screen for a long time (i usually walk away at this point) and eventually a folder with the mac logo pops up and nothing happens from there.
booting from CD also does nothing. the CD starts to spin up, then idles.
i don't have a firewire hard drive to test firewire boot either...
i've tried appleoption+pr and it made the chime twice, but i still get the same results.
any ideas?

Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open ourFirmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:
reset-nvram
set-defaults
reset-all
"The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

well, an external monitor did nothing

That's a positive sign.
when i hold the option key on startup, i get two buttons, (a round arrow and a straight arrow) both of which i am unable to click. The firmware could not find a valid os. Should include icons for each partition or cd with a valid os. Why don't you try boot with the option key with a cd in the drive.
but is there a way i can use open firmware to redirect the boot partition?
I hadn't been able to fathom the syntax... until I listed a bunch of os's.

Why set nvram variable? I've had open-firmware based Pegasos PPC and it simply had boot command, so instead of:

New to Mac - how to re-install when G4 won't boot from CD

Hi all
I am completely new to Mac, so bear with me here. I recently bought three G4's from my employer (they took over some old offices of a company that went bust and left all their equipment, which has been lying around for some years now). Wow, for a PC-guy like me it is quite a switch
Anyways, I managed to get one of the running and re-install with new OS (Panther) as I have the original discs.
However, one of them is causing me some problems. It is running OS X Server and has been setup with password - so when I boot up I get prompted to log on and can't get any further. It read a few places that it should be possible to boot from the install discs and then re-set the passwords. I tried holding down C when booting, but the machine won't boot from the CD. Tried holding C before powering on, before the chime, after the chime, when the logo displays, etc. Nothing helps. The key on the keyboard is working (tried it in the user-name box when I get prompted to log on)
I don't care about the conents of the drives - just want to re-install. But how to do that when the C-key isn't working to get it to boot from CD? Guess one of my problems could be that I don't have Mac keyboard and have to plug a Windows-keyboard into it. Also tried pressing the ALT key at boot up, but that does nothing either.
Help?

It is a server yes. But it doesn't matter though about the lock.
Here's what happened so far which also solved my problem:
- Moved around on the RAM sticks and then managed to boot into OF
- Reset security-mode as described in various forums and guides
- Still couldn't boot from CD - even after resetting PRAM and NVRAM.
- So I searched the net (sorry to my boss for not doing much work today) and when I came home I was armed with many useful hints to do the dance with the machine.
... but just before we stepped onto the dance floor, I noticed a post-it taped to the side of one of the OTHER machines (I bought three from my employer's storage sale and all three from the same company whose offices they took over). And on that post it was two words one of which was Administrator. It turned out that the other one was the password. Dough. So much ado about nothing. But, at least I learned a lot about the Mac-world along the way.
However, when I pop the CD in I cannot see it when I logged on - faulty device? in "ABout this Mac" is shows the DVD-drive just fine. Is it concivable that someone could have disabled it some way? If so, how do I enable it again?
Thanks everybody for all your patience with me

Late 2004 Dual 2.0 G5 + Airport Card = won't boot? then Reset your PRAM!

I bought a remanufactured dual 2.0 G5 and the darn thing would not boot when I put the airport extreme card in - - - the "techs" at apple care were totally, absolutely clueless, it appears that they know less about apple products than I do, I just switched this year from PC to Mac. I was absolutely disappointed at the lack of knowledge and support by the apple care phone techs, it's quite amazing how cluless the techs are. Maybe you have to work your way through layers of people until you get to someone who knows something. The best support is here - on this site - the questions and answers that people post and answer. I love Apple products and will never go back.... but I think the support stinks....

Mac mini (Late 2012): Dual- or Quad-Core?

I'm upgrading from a MacBook (2006) and - as a frequent iPad user - am thinking of just getting a Mac mini. I'm not sure though as wether to get the i5 dual-core or i7 quad-core version.
What I'll be using it for (none of these on a professional level, prosumer at most ;)):
Photo editing (iPhoto, thinking of switching to Aperture)
Web development (Coda, Espresso, local test server)
Designing (Sketch 2)
Full-HD video editing
Web, office, social media, ...
Can I expect a signifcant performance boost at these tasks from the quad-core model or will the differences be barely noticable (also considering most of these applications will be running simultaneously)?
I'll be maxing out RAM from a third party vendor in both cases, HDD capacity is not important and I'm not going to upgrade to SSD or Fusion Drive.
What do you think? Any thoughts appreciated!

Thanks for your insights! My inital goal was being cost-efficient; Fusion Drive is only an option on the quad-core model thus making it 1080 Euros were I live. That's almost an entire new Mac mini which I could buy in 2-3 years. I don't mind CPU intensive tasks taking longer (e.g. rendering final movie) as long as the actual "creative process" runs smoothly (e.g. cutting the movie).
As you both said finding out how/if apps take advantage of multiple cores is not that easy. I guess I'll have a closer look at all the benchmark tests and reviews that will be showing up in the coming weeks.
I think Fusion Drive on a dual-core might boost performance more than just going quad-core, unfortunately this is not an option for the lower end model. Also I want to wait a little to see if Fusion Drive is proprietary Apple hardware or just implemented software-wise (which would mean I could fix a broken drive myself after warranty has expired).
By the way, any guesses on Black Friday sale options (as far as I could find out the Mac mini wasn't included last year)?

Problems with Late 2011 MBP (catalog corrupt, won't boot from USB/CD)

Hello,
I have had some problems with my Late 2011 MBP running OSX 10.8.x (latest update)
I was using Safari when suddenly my screen froze. It has happened a couple of times before but it usually is either: 1.) a black screen for 5 seconds while nothing works responds and then it continues work like nothing happened, or 2.) just a freeze for a moment which goes away within a few seconds. I have visited the official service and they found nothing wrong with my laptop and said that it may have been just random occurrence. This time it froze and as I waited the fans went crazy and had no other option but to shut down from the power button. Later, when I wanted to boot up, it gets to the Apple logo, the circle spins and the small bar below appears and after a second or two, it disappears and then the computer shuts down. I went to recovery mode and used disk utility to verify and repair the problem (which only works to find out the problem, not to fix it, thanks anyway apple) Heres what it showed:

Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
I tried to boot DiskWarrior from a USB and a CD, after pushing enter in the bootable device's screen, I get a continuous loop of 3 beeps and I can't boot from either of the mediums.
I also tried the Single-user mode (Command-s when booting) and the /sbin/fsck -fy said that my HD is not completely verifiable. Also, 3/4 of the files mentioned in disk utility are also mentioned in this process, with errors as forrows: keys out of order, invalid index key, invalid extent entries (7 times), incorrect block counts, number of links and incorrect sizes for the foretold files and invalid catalog record type.
The reason why I'm not doing a clean install is that the last few days I've been in the process of deleting unnecessary items on my laptop so I could make a back-up (as for some reason, Time Machine is awfully slow and a new 600 gb backup would take and enormous amount of time, but that's a problem for another day) and as I had not yet reached the backing up part, my data is locked on this (possibly) corrupt HD. How should I advance and what steps should I take?
My first and most important mission would be to get back into my OS to make a back-up. Then I'd deal with the "not being able to boot form USB nor CD" and the TM problem.
Thank you all in advance,
Martin

Before you even start, consider that there may be no Windows 7 driver support for some of the hardware in your laptop. You won't know which hardware devices and functions are unsupported until you find out the hard way. In some cases, a driver conflict could cripple your computer.
Like most OEMS, Toshiba pre-installs Windows 8 to boot with EFI on a GPT hard drive. Your Windows 7 install disc, on the other hand, most likely boots with a BIOS from an MBR. Therefore, your Windows 7 disc will not boot your computer.
You would need to start by performing a low-level format of your hard drive. This completely erases the disc and its metadata. Then you could boot from your Windows installation disc and try to install Windows 7. How successful you will be depends on driver support.
All things considered, you should stay with Windows 8. Next time, more research before you buy.
