My Mac Pro does not start up

I have a big problem with my MacPro which I bought just 3 months ago. A month ago it started to act up: sometimes it was slow and sometimes it's fine. When I type it's so slow and letters take time to show when typing. Now, it does not boot up or does not start. When I turn it on, it shows just the apple sign but it does not boot up! I need help as I am now out of the US.

The best option is to take advantage of your warrantee and take it to an Apple repair facility.
In the interim, look at this Apple support article and start there:

My mac pro does not start up because then hard disk is formatted

My mac pro does not start up because then hard disk is formatted, How can install the operating system.
regards,
Tassew

Did you erase the hard drive yourself? If not, what exactly are you seeing, and what happened immediately prior to you starting to see it?
Your profile indicates that you are/were running Lion (Mac OS X 10.7.4) on a retina MacBook Pro, so you should be able to hold down command-R at startup to enter recovery mode, and you can reinstall the system from there. But whether or not you need to do something else first depends on your answers to the questions above.

Mac Pro does not start after security update

Just updated my MBP (mid2011, OX ML) with the latest Security Update ; after reboot it does not start. I get the start screen with login and it keeps spinning? Any wisdom here? thx

Hy myneck,
Happy Holidays! The resource below may provide some steps to try if your MacBook Pro won't start.
Troubleshooting: My computer won't turn on - Apple Support
http://support.apple.com/en-us/TS1367
This article discusses what to do if your Mac won't turn on. To differentiate this from a display issue, be sure that when you press the power button:
You don't hear a startup chime.
You don't hear any fan or drive noise.
There is no video on your built-in or external display
If your computer has power but doesn't display any video, it may have one or more of these similar symptoms when you press the power button:
You may hear a startup chime.
You may hear fan or drive noise.
You may see a light from the Sleep LED (if your Mac has one).
Pressing the Caps Lock key on the keyboard causes it to light.
If any of these display-related conditions occur, see Troubleshooting: My computer has no video instead. Otherwise, continue with this article.
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).

TS3048 My early 2009 Mac Pro does not connect via bluetooth to my sound bar or bluetooth mini speakers. Both my wireless keyboard and mouse have no problems connecting. What do I need to do to connect to external bluetooth devices?

My early 2009 Mac Pro does not connect via bluetooth to my sound bar or bluetooth mini speakers. Both my wireless keyboard and mouse have no problems connecting. What do I need to do to connect to external bluetooth devices?

I would always have a wired keyboard and mouse on hand (need not be expensive ... any cheap wired devices will work). "Emergency recovery" procedures can activate features in random order, so the opportunity to select a recovery partition may pass before the wireless devices are recognized.
That will let you select the "turn on Bluetooth" icon.

After upgrading to Mavericks my Mac Pro does not open my double CD drives when I hit eject in the menu bar it locks up (please Help)?

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report — it will be very long and not helpful.

New Macbook Pro does not start up after updating...HELP!!!

Hi,
My new Macbook Pro does not start up after it got updated. The first time I used it, it was perfect. I updated it and restarted it when it told me to but it doesn't boot. It shows an apple and a spinning circle when it turns on but that's it.
Can somebody please help me?

You should probably post your question in the MacBook Pro discussions:

Mac Pro does not auto-sleep (manual sleeping if fine!)

I have a small annoyance with my 2009 (Nehalem) Mac Pro I am wondering if someone can help with, or suggest something, please:
The Mac Pro does not auto-sleep; ever. I have played around with the sleep time settings, and enabled or disabled the 'sleep drives' option, but to no avail. Mac Pro will stay on, no matter if I am logged on OR even on the 'log on users' screen.
That said, I can sleep the Mac Pro manually at any time, and without any problems; it stays asleep without a hitch, and wake-up is flawless.
There is nothing in the console log that would tell me why the auto sleep doesn't function. I deleted the sleep plist and re-set, but again, no change.
Any ideas? Not sure what could signal the system to not do auto-sleep?
It's running 10.6.3.
Cheers,
Dan

Exactly the same problems as those described above: forced sleep works (by using the power button or closing the lid) but automatic sleep doesn't (using 'Energy Saving' preferences).
Tried every single piece of advice here and on other posts: reset PRAM/ SMC, verified disc, repaired permissions, deleted the power saving preference files, cleared caches & history, restarted in every conceivable mode... The only things that worked were safe boot and creating a new user account which means it must be a software issue.
Disabled/ removed/ paused/ reinstalled every piece of software I could but to no avail. The most frustrating thing? Having to wait for 5 mins every time I tried something to check whether the damned thing was going to go to sleep.
In the end, and in desperation, I took the advice of Dino X and downloaded PleaseSleep. Success! A genius piece of software. It forces sleep when the Energy Saver preferences cut in but, even if I don't set exceptions, it won't force sleep if there's a DVD playing (for example).
Only had the Mac for a few months and I'll never go back to that other, unmentionable operating system; the Mac's just too good but I'm vexed that I'm having to use third party software to get it to work as it should (and was) - feels like a bit of a Win*s solution to me.

My mac book pro does not start but has error message with a question mark on screen. took it in and was told probably the hard drive as could not reconize it so bought new one but still not connecting.what do i do

My mac book pro does not connect but shows an error message with a question mark on the screen.I took it to a retailer that said it was not reconizing the hard drive.He said i needed a new hard drive but it may be something else as well but he was sure a new hard drive would fix it.So putting faith in someone who deals with them i purchased a new hard drive to find it was still not working although he said the computer did know reconize the hard drive and i may have to send it away to get it checked .After already paying 120 pounds for a new hard drive and they wanting another 80.00 pounds to diagnose it i am a little sceptical.
That's why i am interested on anyone's help.

Welcome to the Apple Support Communities
I think that your Mac detects your hard disk, but the problem is that your new hard disk doesn't contain any operating system, so your Mac doesn't find any bootable partition and you see a question mark.
If your Mac came with DVDs, insert the Mac OS X Install DVD and hold the C key while your Mac is starting. Then, just install Mac OS X. If the hard disk isn't prepared to install Mac OS X, you will have to erase it using "Mac OS Extended (Journaled)". See > http://pondini.org/OSX/DU1.html

MacBook pro does not start. How can I back to Mac OS X Lion?

I have a MacBook Pro. On my MacBook i made three partition, then I installed window 8. After that I started windos and try to delete third partition by Administrator tool from windows operating system. After that my MacBook does not start. How can I back to Mac OS X Lion?
After that I again install windows 8 from a DVD. Windows start well, but I can not start Mac OS system, may be it was 10.6. Sever times I tried to install OS X Lion 10.7 thought DVD, I could not. On MacBook I have a lot of important data.
What can I do. I want to a complete suggestion. Please help me to solve the problem.
My MacBook Pro model no. A1286.

You installed Windows improperly the result of which was to wipe out the bootloader for OS X. You can give this a try:
Boot Using OPTION key:
1. Restart the computer.
2. Immediately after the chime press and hold down the
"OPTION" key.
3. Release the key when the boot manager appears.
4. Select the OS X disk icon from which you want to boot.
5. Click on the arrow button below the icon.
If you are still unable to boot from the OS X volume then you will need to reinstall OS X:
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
This will destroy the Windows bootloader so you cannot boot into Windows. The solution is to remove all the partitions on the drive except the OS X partition, then expand the OS X partition to take up the entire drive.
Use Boot Camp Assistant in the Utilities folder to create a Windows partition on which you can install Windows. You cannot have any other partitions on the drive besides these two.
Now given all the above you may be able to install a third-party bootloader that would work with the setup you now have: Boot Runner 1.4.

My mac book pro does not start properly. It goes past logo then grey screen I cannot access my

MMy MacBook pro will not start up. It goes past the apple logo then only a grey screen, sometimes a blue one with vertical stripes. I have tried starting from a disc also by using different keys, but with the same result. At one point i heard three beeps then a pause repeated. Please help.

See if you can run an Apple Hardware Test:

Note an error free AHT is not definitive.
If addition to the possibility of a RAM problem, the vertical stripes on the blue screen is not a good sign.

My Mac Pro does not switch off.

It worked before Lion. Installed 10.7 and also upgraded to 10.7.1 but, on both cases, it does not switch-off. To be precise it "sometimes" switch-off but many times it does not. Let's say once on 15 times... With Leopard I nevere had this problem. (it persists also after a PRAM reset). I also run a second problem but only once and only upgrading to 10.7.1 (not to 10.7). It says that my RAM was on wrong position.. I had to remove and install the RAM again and it worked.
Any other case like this? (This append only on my MacPro - early 2009. On my MacBook and my MacBook Pro OSX Lion works fine).

Is there a pattern to the chimes, or are they simply random, as if the Mac is repeatedly rebooting on its own?
Have you tried a "Safe Boot"? Press and hold a Shift key as you power up the Mac. Does it start then?
If it starts at all "Safe Boot" will take much longer than usual, that's normal. Shutting down will take longer also. Try it.

Mac Pro will not start up. Firmware or graphics problem?

A really weird thing happened to my MacPro 1,1. It has been working fine for the last 5 years until today when I was running Parallels and suddenly the screen got those thin, horizontal, wavy, purple lines all over the place and cursor turned into a beachball. I tried to Force Quit Parallels but it didn't work. I had to hold power button to force the computer to shut down.
I am running 10.6.8 and just yesterday I installed some updates but these were minor: Safari, iTunes, Java. The computer worked fine after those have been installed.
Now the scary thing - the computer does not start up properly. When I press the power button I hear the chime but then I see the grey Apple logo with those purple, wavy lines in it. The computer seems to find the system on the hard drive but when it gets to the login screen it doesn't display the login window or the background properly. Instead I get just a plain grey color with a cursor (arrow) that moments later turns into a beachball.
I unplugged everything to bare minimum and tried to start it up from Snow Leopard CD. It finds the CD but the same thing happens - I don't see the CD installation menu, just a blank grey screen.
This makes me think: either the graphics card died (GeForce 7300GT) or it is some OpenFirmware problem.
I removed the card from its slot, blew off some dust and reset it. No change. I tried resetting SMC as well (Even though the instructions are a bit weird: unplug power, wait, plug it back in, wait, press power). I do have non-Apple RAM installed (6GB total) but it doesn't seem to be RAM issue - all status LEDs on both riser cards just blink red briefly during power up.
Should I plan a trip to the Genius Bar or do I own now a very expensive paperweight?
Any ideas? I would greatly appreciate your help.

I found your thread very helpful. I have a 2009 mac pro 3,1 that seems to be doing similar things. It was working fine then occasionally the screen would flicker and then freeze the system. had to power off to get out of it. Now it won't boot. I get purple and white vertical lines and the apple with the pinwheel. the pinwheel stops after a while and thats it. i tried booting from the cd and get to the harware test but the screen is split left and right. really unreadable. i suspect the graphics card (geforce ) so i tried booting without the card installed. i believe it still did not complete the boot. my question is should i be able to boot without a graphics card installed? any thoughts or advice would be appreciated.

1st-gen Mac Pro does not boot in any way, not even in safe mode

I have a 1st-generation Mac Pro with the graphics card upgraded to NVIDIA GeForce 8800 GT; running 10.7.2. I have had no problems with the machine since I bought it in May 2007... until now. Specifically, the machine suddenly became non-responsive, froze (I do not remember this ever happening before), so I had to power it down and restart. After that, the machine does not boot in any way: does not start up with the Option key; no FireWire target mode; does not start up even in the safe mode. All I get when I power the machine up is the folllowing endless loop: (1) the display unit (30" Apple Cinema Display) waking up from sleep (white light going off) and (2) a flicker of white on the display while the optical drive sounds like checking for any inserted media... then again the display going to sleep for a few seconds and steps (1) and (2).
I could really use help here. Thank you in advance.

Linc:
I am also sure it is a hardware fault. I have tried to run the Apple Hardware Test from the orginal system disc: I opened the optical drive tray with a paper clip, inserted the disc and powered up the machine. However the machine only spinned up the disc, turned the display to standby, spinned up and standby, etc.
What kind of hardware fault could it be?
(1) the display unit (30" Apple CInema Display) -- I presume unlikely, since the computer should boot even with a defunct display unit or no display unit at all, for that matter;
(2) the graphics card
or
(3) the logic board?
