Mac Pro startup problems

I've been having intermittent startup/sleep problems. One of two things happens...I put it to sleep and then when I come back later and tap the keyboard or touch the mouse, I hear it starting up, but the screen doesn't come on. To resolve this, I could usually sleep it with the power button and then try waking it again. Or I just force a restart by holding the power button down...of course losing whatever I hadn't saved.
The other thing that has been happening more frequently is that when I try to force a restart by holding the power button down, the cinema display doesn't turn on.
Apple wants me to disconnect all my peripherals and add them one at a time. I have a bunch of peripherals, and since this is an intermittent problem, I think it'll be difficult to diagnose. As well, i'm a quadriplegic and have no use of my hands, making plugging and unplugging a difficult task. My keyboard is plugged in to my monitor, which is plugged in to a surge protector. As a possible solution, I flipped off the surge, pushed in the power button til right before hearing the chime, the flipped on the surge before the chime and the monitor turns on. Sometimes. And sometimes when it does turn on, my Mac boots with the Boot Camp partition...even though I have chosen it to start with Leopard.
I've had on-site service and they changed out the logic board and video card.
This is frustrating. I can't bring it in or send it in because I would think I would need to include all the peripherals to replicate the problem at home.
Oh...it also seems if I just let it "sit there" for a long period of time, I can eventually boot it fine. Lately, this superstition hasn't worked.
I've found a lot of the Discussions with similar boot/sleep problems with the Mac Pro, but none have helped me.
Any help would be appreciated.

This has been an ongoing issue since Panther. It is old as the hills and what it is isn't as easy to remedy as it sounds. There is an issue where, when the machine goes to sleep, the PCI bus shuts off and, upon awaking it doesn't power the video card bus up so, there's no display. There used to be mod to allow the PPC machines to keep the card active and one would go into Terminal and write it in and reset it in such a way to get it to work. However, in the Intel machines, I don't know what that is. IF there's other PCI cards running on that machine that does not support sleep, that same end result will happen. I got so fed up with patching it only to run a hi end audio card in there that did not support sleep and it went right back to a black screen. Best thing to do is to not to use sleep at all. I set it to never.
Oh, one more thing; there was an issue with some power supplies for the monitors. By simply unplugging it and reconnecting it, the monitor would fire up. I had that happen too with my Apple monitor. The thing was, it just never worked consistent from Panther as I recall.

Early 2008 Mac Pro Startup Problems.

Hi all,
I have an Early 2008 Mac Pro - 2x 2.8ghz Intel Xeon Quad Core processors, 12 gigs of Ram, 1x Nvidia 8800GT graphics card and I am running Windows Vista 64bit through bootcamp. I am running Snow Leopard. I have one monitor it is a Samsung 226bw - 22inch and it is connected via dvi and vga on the monitor side.
I have recently had my computer updated to the latest 10.65 (something like that).
Anyway my current problem is that:
a)The computer does not load up any operating systems and it is just a blank screen.
b) Sometimes all you hear is the Apple loading Chime "doong" constantly, and a blank screen.
c) Sometimes I can get to the windows selection screen for safe mode. I pick safe mode but it just goes to a blank screen. Also the monitor does not pick any signals up as it goes no source etc.
What I have tried:
a) I have changed the monitor cables 3 different ones.
b) I have taken all the other hard drives out.
c) I cannot get into Mac OSX or Windows Vista ( however Vista is the default OS right now)
d) I can connect my main hdd and copy all my windows stuff, but I cannot see any of the apple osx.
My suspicions are it is graphics card,or hard drive related.
I have ordered a new graphics card a ATI Radeon 5770 ( wont come for 6days) and I have a new hard drive a WD Black Caviar 1tb.
My Questions:
a) I would like to know what your ideas are on my current situation and Mac Pro symptons.
b) Is there a way I could format the WD Black Caviar HDD to a Mac Extended one in Windows on my laptop connected via sata?
c) If "b" is possible could I then use my Mac Pro/Mac OSX or snow leopard discs to create a OSX for my Mac Pro?
d) Or should I just wait for my graphics card to come and see if is just the Nvidia 8800gt failing?
e) If it is not the graphics card then do you believe it is the hard drive? or could it be something else?
Any assistance would be kindly appreciated.
KInd Regards
Bobby

Vista on its own hard drive? Windows doesn't like to move the drive bay.
you could boot from Vista DVD (I'd upgrade to Windows 7 SP1 when possible)
clone backups - for both
emergency boot drive / OS X DVD - you can, and should, always have more than one Mac OS boot volume handy. So yes use 10.6 DVD
Preventative and disk maintenance (Disk Warrior etc)
You would need something like MacDrive8 or Paragon HFS8 to really have good access to HFS from Vista assuming the volume is safe to mount and access.

Lacie Speakers and Mac Pro Firewire problem waking from sleep and loud feed

Lacie Speakers and Mac Pro Firewire problem waking from sleep and loud feedback. I had a powermac before this with the speakers and it worked fine. But the mac pro is having these issues. Is it the firewire port or the speakers or (and most likely) just a firmware glitch with mac pro? Anyone else see these issues?

http://web.mac.com/jerimydulay/Site/MyAlbums/Pages/Lacie_FirewireMIDI.html
Here is my audio settings. For some reason I wish I could remember what I did. It was actually the Apple Store tech in the Unversity Village in Seattle that gave me the idea and I swear I had to change the settings in MIDI setup. Now that Leopard is out it seems the MIDI stuff has been redone. I included screenshots of my MIDI setup as it is currently to see if you see something different on your computers. Let me know!

Mac Pro Fan Problem

Hi, I have been having some problems with a Mac Pro I have been working with. At the Start-up the Fan goes to top speed and once it logs-in the fan is still pretty loud. I've checking the Temperature of all the computer parts via a Temperature Diode, and its normal and not high. After searching the internet for hours looking for posts that were for the Mac Pro and not for the MacBook Pro (which comes up in about all the searches using the words Mac Pro Fan Problem) and I found some software all of which is not for Mac Pro's. Is there any application I can run do reduce the RPM of the Fans, Reset the Fan Speeds to only turn on when it get hot, or something along those lines.

Thats odd, seeing as Apple have it listed in the Support article:
To reset the SMC on a Mac Pro:
1) From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
2) Unplug all cables from the computer, including the power cord and any display cables.
3) Wait at least fifteen seconds.
4) Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer.
5) Press the power button to start up your computer.
It does exactly the same thing as the SMC_RST button, simply by removing all power from the system. I would assume the reason for this would be that the SMC settings are stored in RAM, which is erased once the power is removed from the board, hence the minimum 15 secs wait which gives time for the capacitors in the power supply and system to discharge.
So yeah, it does do the trick, or has done for me in the past a few times.

Mac Pro Boot Problems After 10.6.2 Update

After installing the latest version of snow leopard I am now having boot problems on my mac pro.
Symptoms;
-Screen resolution is incorrect at apple splash screen.
-Takes a lot longer than usual to boot.
-Once booted the blue tooth magic mouse isn't imediately reckonised, takes a while to find that.
-Once the mouse is finally reckonised it can move around but can't click on anything or bring up the dock. Tried a wired mouse, had the same problem.
-The keyboard is also not appearing to do anything, none of the shortcuts or quick keys work..
Had exactly the same problem after 3 restarts but on the 4th after leaving it for a good 20-30minutes it setled down and everything was working okay. However this is a recurring problem as I had the same thing yesterday...
I have a my 10.5.8 system backed up on an external so I am running from that at the moment. Don't want to go back to snowy til these problems are solved.
Any help will be greatly appreciated!
Martin

Try Safe Mode (It will take more time to startup in Safe Mode because it runs a directory check.)
Let us know.

Mac Pro memory problems, or...?

I've been experiencing intermittent "goofy behavior":
1. fine horizontal black line across a window, today I had one half across the menu bar.
2. hangs -- i.e., will not respond to any keypress, mouse click, etc.
3. in the course of working through the usual list of troubleshooting steps I discovered that my Mac Pro does not recognize any of the startup keys http://option, cmd-opt-PR, shift, cmd-S, ...
- I have substituted an older Mac keyboard for the aluminum keyboard - still no startup keys
4. I've done the usual preferences, disk maintenance, etc.;
5. I can't run Hardware Test due to non-functioning startup keys [need D key for h/w test]
6. When the CPU wouldn't wake from sleep I got the below post-restart report.
7. I've run memtest two full nights, no errors detected.
8. I've removed the 2GB of OWC extra memory, running with Apple stock 1GB to see...
Any suggestions that may accelerate isolation would be much appreciated. Restart report follows:

Sadly, still seeing video artifacts -- I now have some evidence these are RAM-related.

I ran for a while with OWC removed -- still saw artifacts, though possibly less frequent.
After fixing the startup key problem I was able to run the Hardware Test extended test this AM. Which reported no errors.
I then swapped OWC and Apple -- ran for several hours with no artifacts, then "screen rash" reoccurred followed very shortly by a hang [no mouse nor keyboard input], hard restart.
I've run the digLloyd run-stress-test to heat up RAM, then Rember/memtest -- no errors.
Does anyone know definitely whether RAM Riser A or B is used first?
Other suggestions?

Mac pro 2008 problems

I'm having problems with my Mac Pro 2 x 3.2 GHz Quad-Core Intel Xeon ,early 2008 model. It still works fast enough for all my apps, running CS6. Issues are
Software hanging, pen drives not showing in the finder sometimes, issues with CD drive too. A ? over startup drive.
I'm constantly having to shut it down with the power button, and to reboot. It rarely restarts properly.
I'm on Yosemite, and can't update iphoto. I have intermitent problems with itunes, its not finding iphones when plugged in?
Is there a fix it that I can download from the internet to fix all these bugging issues, details of my system below. Help please?
Model Name:    Mac Pro
Model Identifier:    MacPro3,1
Processor Name:    Quad-Core Intel Xeon

Number of Processors:    2
Total Number of Cores:    8

Get a new system SSD boot drive. Do a clean install. Be careful what you import. SSD will give your system some juice.
Clone your system with Carbon Copy Cloner and enable the hidden advanced preference option - custom clone feature - to do a checksum on all files copied.
From your description, you should be doing both a SAFE BOOT and Recovery Mode to Repair Disk to fix the disk directory. Zap the PRAM from cold start and reset the STARTUP DISK setting.
I would not trust or rely on that drive and system as is for now.
Another, never use an unstable drive to install, or write to, should be using a backup spare system at this point.
Co clone it to SSD with CCC - after using DU and Safe Boot, and uninstalling any "non-essential" 3rd party app or background process and utilities. Lean, mean, stable and faster performance without the extras.
CS6: I would go for more RAM . FBDIMMs are downright affordable, look for NEMIX on Amazon while looking for Samsung 850 or Samsung XP941. Two: one for system, one for scratch, would be ideal. An EVGA 960 GTX to provide CUDA to CS6 maybe later or 970, more VRAM the better.

Early-2008 Mac Pro startup - sometimes it does, sometimes it don't.

I have an early-2008 Mac Pro running Mavericks. Having issues with start up - powering up is intermittent - sometimes it does, sometimes it don't. I have had some success by unplugging it overnight, and it boots up once plugged back in the AM. I have been able to restart and zap the PRAM; I have also changed the battery. Thoughts?

You could have a problem with file corruption or your hard drive is going south. I would try moving your system to another hard drive then set that drive as the startup. See if the problem is resolved.
You can also try reinstalling Mavericks:
Reinstall Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Mavericks
OS X Mavericks- Reinstall OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Windows 8.1 Pro on Mac pro resolution problem

I have created a partition for windows 8.1 pro on my 13' retina display mac pro via boot camp, everything is fine except the resolution, when i open the browser, i could see pixels, the words aren't very sharp, but this isn't my biggest problem, when i open the Solidworks software i'm working on, the icons are too small, or the texts are too big for their boxes. what is happening here? anyone knows what is all about, or how to fix this? changing the resolution of the display didn't solve the problem.

This is how the words look like in the browser page, you could see pixels. The maximum resolution for this machine is 2560*1600

Mac Pro boot problem-Get "I have no name!" error message after possible KP

I think I'm having a kernel panic... and trying to keep from doing so myself
3GHz Mac Pro/4GB RAM, 250GB boot drive and three 400GB drives as a RAID for video captures.
I'm still in the process of getting the machine set up with software.
Demo machine from an Apple Authorized VAR that has been running in his office for several weeks. Had installed Final Cut Studio Monday, allowed Software Update to update the Apple software, including the OS.
Edited quite happily with FCP on a multiclip project... and did other things over the last several days.
Had no problems until a couple of hours ago after adding a number of fonts... which may turn out to be part of the problem... or not.
Rebooted the machine, and after what seemed like a VERRRRRRY long time of gray screen with spinning gear icon, the screen goes black with a cursor in the upper left corner.
About :30 later, text appears: "3Ghz-MacPro:/ I have no name!#" followed maybe ten seconds later by "SIOCPROTOATTACH_IN6: en0 error17" and "SIOCPROTOATTACH_IN6: en1 error17"
Screen clears back to cursor... then "3Ghz-MacPro:/ I have no name!#" reappears... and eventually the cycle starts again.
I would infer that en0 and en1 are the two ethernet ports.
I've popped the install disc in, booted to it (which took a while to do) and used Disk Utility to verify the disk. No problems found. Repaired it anyway.
Verified permissions, which found a couple of issues in the library with some files not essential to booting. Repaired those. Rebooted.
Same cycle as above with "no name."
Ran Apple Hardware test (the quick one) and it found no hardware problems.
Am waiting to see whether the AppleCare TechTool Deluxe will boot. Spinning gear continues as I write this (7-8 minutes??)... now wondering whether it's 10.4.x for Intel Macs as it spins.
After waiting a while... decided to go back to the install disk and see whether I can install 10.4.7 to a handy FireWire drive and boot from that...
then remove (or turn off with FontBook) all the fonts I just installed and see whether it'll boot from the internal.
More later. Am watching e-mail on another machine so feel free to offer suggestions.
Thanks
Ted.
3GHz Mac Pro-1GHz eMac-G3 400MHz Lombard Mac OS X (10.4.8)

I installed 10.4.7 onto the RAID so I could see whether it would boot OK, and to swap font folders out so that only the OS installed ones (from the RAID install) were present on the boot's original install.
Booted from the RAID just fine... and was able to do the font folder swap in the main font and user font folders.
Trying to then boot from the boot disk didn't make a difference. Same kernel panic with the text as described before.
Did an "archive and install" onto the boot disk and it came up fine on the fresh OS.
Updated QT and then the OS to 10.4.8 using Software Update (which I understand from the Apple info site is the "delta" version. Combo is also available, and it updates any 10.4.x version to 10.4.8)
Moved over some items in various library folders from the previous system to make the ProApps happy (only Motion's not working) and will get a project out the door today.
Will ultimately wipe the drive and go from scratch on the OS and Apps again.
Looking forward to half a day of intimacy with my Mac Pro and software disks this weekend.
Thanks.
Would still like to know what happened under the hood to cause the problem in the first place... so I can avoid doing anything I might have done to cause the problem... or to avoid other snafus.
Ted
Message was edited by: Ted Langdell to clarify the results booting from the RAID and from the boot after font folder swapping.

Mac Pro Boot Problems. Kona 3?

I'm having booting problems with a Mac Pro. It's got a kona 3 card in one of the PCI slots, and we've been tinkering with it to try to get the audio to work right. However, I've been having huge problems whenever I try to restart the computer. After hitting the power button, or telling it to restart the screen goes to black and sometimes I hear a chime. However, the computer does not boot any further. Then, after holding the power button down and restarting the computer, I can sometimes get the computer to boot normally.
I suspect the Kona card is causing some of the problems. I have multiple hard drives on the system, and I have the ability to boot onto two separate drives in 10.5.8. Both drives are having the same problems.
it's a 2x2.8ghz quad-core Intel Xeon with 10gb of ram. The Kona card is in slot 2. Slot 3 has also been tried, but similar problems remained.

removed kona card. uninstalled aja programs. restart problems still persisting.

MAC PRO USB Problem - Traced to bad Apple Keyboard Extension Cable

I found a fix to a problem synching to my itunes Library on my early 2008 MAC PRO. The Apple supplied USB extension cable for the keyboard was defective.
The symptoms were hangs in itunes and finder synching to iPods and transferring data to USB hard drives. The iPods and hard drives never lost power and no errors/log entries were made. The transfers simply stalled and would not continue. itunes and finder would hang until the drive or ipod was removed. These devices were installed directly to USB ports on the MAC PRO. No other USB devices were connected except for the aluminum keyboard and mighty mouse; the mouse was connected to the keyboard. The keyboard was connected using the USB extension cable that shipped with the MAC PRO.
Hardware diagnostics were all clear. The keyboard and mouse never had any connection problems. Only itunes syncs and hard drive copies would fail; these would occur at random times. I had an open ticket with Apple to have the logic board replaced as it was diagnosed to be a hardware/USB problem.
Removal or replacement of the extension cable on the keyboard (which was connected to a different USB port and NOT in the USB chain with the ipod and hard drives) permanently fixed the problem. I cancelled the Apple HW replacement.
I have noted several posts with others having problems with USB ports and devices. I wonder if Apple has an unknown problem with bad keyboard extension cables.

I think you may be onto something there. I'm just a few weeks into my second Mac Pro and again it's having the same USB problems which led Apple to give me a replacement machine previously. I went through several weeks of considerable testing with Apple Engineers prior to that - an Apple Care application to collect data from my machine, Apple Developer USB prober and two clean installs. The latest machine initially showed no sign of the problem then it started again - 2 iPods "can not be read or written to" part way through sync, Aperture quitting importing from USB SD card reader, USB drives dismounting etc. So I pulled out the Aluminium keyboard and, lo and behold, the iPods managed to get all the way through synching without errors. I really like the alu keyboard so it's a huge shame that it might be the cause of all my problems so far - and the Mac Pro is otherwise a beautiful computer.
But is this really a hardware problem of the internal USB cards and power management or supply?

Late 2013 Mac Pro graphics problem

I have a late 2013 Mac Pro with dual AMD FirePro D300's. Although this could be coincidence, it appears that after updating to 10.10.2, I find my graphics "freeze" after a random period of time (I updated late last week). I can unfreeze by rebooting, or by unplugging the HDMI cable and plugging it back in again. In the latter case, it takes about 30 seconds for the graphics to re-enable, and they are very sluggish after they do re-enable. I have run the standard Apple diagnostics to no avail. Has anyone else seen anything like this? Any suggestions? Any help would be great! Thank you in advance.

Thanks for this response. With nothing else to go on, I guess I have to assume it is some sort of bug somewhere. In looking at the console log, what I see is causing the display to be slow after I unplug the hdmi cable and plug it back in again is what appear to be UI update disables:
2/4/15 5:33:37.955 PM WindowServer[145]: disable_update_timeout: UI updates were forcibly disabled by application "Google Chrome" for over 1.00 seconds. Server has re-enabled them.
2/4/15 5:33:37.963 PM WindowServer[145]: common_reenable_update: UI updates were finally reenabled by application "Google Chrome" after 1.01 seconds (server forcibly re-enabled them after 1.00 seconds)
This does not happen prior to the GPU crash; which from the console log appears to be what hangs the system in the first place.
Note that it is not just Google Chrome that is doing this, every application I use results in the same message. Forcing the WindowServer to quit doesn't do anything (other than log me out).
I am frustrated by this. Googling these issues shows many many other people have similar problems. Being a long time and loyal Apple customer, I am very disappointed........

New Mac Pro USB Problems!

It seems the new Mac Pro cannot recognize certain devices. Such as my Access Virus Ti synthesizer- users cannot get the Mac to recognize the USB connection from the Virus. Please help. I'm losing my mind after 7 hours trying to figure it out and the only indication is that the USB ports on the new mac are possibly incompatible... Please tell me I can still use my $3000 instrument with my new $4500 mac pro which i just bought SPECIFICALLY to use with this VIrus Ti synthesizer!
Link to Virus Ti user forums showing other people with the same problemhttp://www.virus.info/forum/index.php/Thread/5522-MacPro-trashcan-and-TI-Anyone- got-it-working/?postID=28004&highlight=trash%2Bcan#post28004

From what you said it appears that the synthesizer is not compatible. That would be a problem for the synthesizer manufacturer to resolve.

Radeon X1900 and mac pro graphics problems

Hi all,
i've a mac pro with two xeon cpu's (2,66GHz) in it. 2GB main memory and a radeon X1900 graphics card. on this mac i use bootcamp beta 1.4, installed the newest driver for this version from the apple support side. also i have updated the graphics FW to the newest version. so all things are on up to date.
my problem is the following: if I play some very graphics intensiv games like STALKER or BIOSHOCK (yes i use my mac for works and sometimes to play), it seems that the graphics card will be to hot. I get a lot of pixel errors. horiz. lines and after a while windows xp is freezeing. so I must reboot the maschine. also VPU recovery comes up.
I've tried several settings (800x600/1024x768/until maximum). 2-3 minutes the game is running well. after that my fans spin up like a plane, get the errors on the pixel side and the game crashes or windows xp is freezing.
i don't know any solution yet. can anyone help me? have some others the same problem?
many thanks
Andy

Hi There,
I was having the exact same problem playing command and conquer 3 in Win XP. I'd play for about 5 minutes or so with the fans spinning at full speed (sounding like the mac was about to 'takeoff'), and then it would just crash.
I followed the advice here, took the graphics card out, clean the dust out and hey presto, the problem was fixed! My MacPro is about 6 months and i was surprised how much dust had got clogged up in there!
