Mac Pro when I turn it on shows no video signal input
When I turn my Mac Pro on the screen is black and it shows " no video input" . how can I solve this problem?
Many of the graphics cards shipped in 2008 and older macs have gotten too hot or too dusty over the years and burned themselves out.
Consider upgrading to an Apple-firmware 5770 (about US$250) that works in every model Mac Pro running 10.6.5 or later.
Other trivia that may help:
The caps lock key is under software control. If it still operates as expected, the software is running, even with no picture.
Control-Eject on the keyboard brings up this dialog box in a fully operational Mac OS X, and not otherwise. The default to shutdown is taken with the return key:

I can't start my macbook pro because I turned it off when I got a trojan on my mac. When I turn on my mac I get the message that my computer restarted because of a problem. Then it turns off again and turns on again and it starts all over. What can I do?
Boot into your recovery partition (restart, hold down ⌘R until you see the Apple logo), and use Disk Utility to repair your hard drive. Repair permissions too while you're there. OS X: About OS X Recovery

16 mo young Mac Pro will not turn on. Dead. Why. No problems ever! Installed Yosemite and did not boot up after. Did that kill it? To young to die. What happened?what do I do now??????? Help!
Note that you don't have a Mac Pro as stated. Your profile says you have a MacBook Pro. Please clarify as they are entirely different computers. If nothing below works for you, then make a Genius Appointment and take it in for service.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
COMMAND and R keys until the Utilities 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.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -

On my Mac Pro, when I send emails, it always gives me the option of adding an attachment with a paper clip.
Today, the paperclip has vanished. What do I do ?

Just bought new Mac pro when I sync my iPhone 4 i lost all my contacts on the phone .tried restoring from backup no luck .is there any way I can retrieve my contacts
Why don't you just restore the to your pc from your most recent backup? You'll get the warning about erasing the media on the phone, but since you'll have all of your media and apps restored from backup, you shouldn't have much of a problem.

On mac pro when I boot up it tells me windows wa not shut down properly
First I am new to apple. I added windows to my Mac. When I turn it on it tells me windows was improperly shut down, may lose data
How did you add WIndows: Boot Camp, Parallels, Fusion, something else?
Were you running Windows when you shut down?
Did you in fact shut down Windows properly before you shut down the computer or the virtual machine? -
My HP Pavilion a 6130n shows no video signal
My HP Pavilion a 6130n shows no video signal via aga. Attached another monitor via dvi. Still no video signal.
Any troubleshooting suggestions?
This question was solved.
View Solution.Hi,
Does your PC have a discrete video card or just the on board graphics processor with a VGA connector?
If you are using a HP monitor then try a monitor reset. Unplug the monitor’s power cord and hold down the monitor’s power button for 30-60 seconds. Plug the monitor back in and power it up. check the monitor's internal source selection and make sure that it is set to VGA.
Test the monitor and cable using just VGA on another PC to ensure that those components are good. Alternatively, use a known good monitor and VGA cable (without using adapters).
The other suggestion would be to locate a video card that is rated to work with the 250 watt power supply in your PC. There are very few video cards that are rated by the manufacturer to work with a 250 watt PC. A new power supply and video card might be close to $100.

Should I turn off my Mac Pro when not in use or leave it running?
I have been told I should never turn off my computer by some people, and others say that I should always turn it off when not in use! I use my Mac Pro primarily for music recording/editing in my home studio or word processing. Now that I have an iPad I use that for web browsing, email, FBing, etc. and I find myself on my Mac Pro a lot less. I get the basis behind both trains of thought; those who leave it on feel always stopping and starting up puts unnecessary wear on the moving disks, and those who shut down think if the parts are always moving they are bound to wear out faster. I am not as concerned with conserving power as I am with keeping my machine safe! If you have any information on this topic I would love to hear it. Thanks!
Providing you have a robust firewal and are not worried as a result about being hacked then leave it turned on and allow it to sleep. Make sure you allow the screen to sleep as well a that is the item that is more prone to damage by being left on all the time.
I never turn my machine off, never have with any of my Macs ever since my first one back in 1979-ish and have never suffered any adverse affects. Today, the power drain is so small when allowed to sleep that I doubt they would offend even the ardent 'turn off everything and pull out the plug to save the planet' person.
If you have an iPad or iPod synced with the Mac for email and iCal and address Book etc. then if you leave it on it should be up to date as soon as you return home, mine is anyway. With iCloud coming out very soon that may come into play even more so with all its advance pushing etc. Just a thought.
One advantage in leaving the machine on (sleep) is that you can access it from anywhere in the world should the need arise with the appropriate settings, which you can't if you turn it off.
Leave it on. -
My new cinema display fro mac pro just went dark. When I 1st bought it, the display wouldn't turn on.I called support and they gave me a keyboard shortcut - something like Option+R+L - that you held down for 2 restart cycles. Then it magically turned on. I can't remember the sequence and I'm afraid to guess! I'd appreciate if anyone knows the trick. I'm also wondering if I should bring this display back...
Cassandra from Apple Support ROCKS!!!! She's a supervisor somewhere and should have a raise. Pleasant, smart and professional with a customer who wouldn't take "I don't know" for an answer.
If your cinema display goes dark:
1. shut down computer
2. restart
3. immediately hold down Command-Option-P-R keys simultaneously for a few minutes (seems forever)
4. keep holding keys for 2 startup cycles
5. release and go back to work if you're lucky to have a restored screen -

I bought a Mac Pro last May, and today our mains fuse went, and it will no longer turn on. There is no smell of burning, and it is pretty dust free. I changed the fuse in the plug to no avail.
Is there anything I can do? I don't have applecare.
What support can I get? It's under 12months old, so under limited warranty. I am no where near an apple store though, so can't just walk in.You should have been running your system on a UPS for one.
When you need to reset the system, there is an SMC RESET button under drive #4 or zap pram/nvram or unplug from the wall for 30 seconds.
A Mac Pro should be on its own circuit with only little other equipment (no space heaters, window A/C, refrig etc).

My Mac Pro won't turn on, what should I do?
In the morning I used my MacBook's hard drive with an USB-SATA cabel as the "booting" hard drive. When I turned on the Mac Pro I pressed alt to choose my MacBook's hard drive as the primary driver. Everything went right.
I wanted to copy my files to my server, it was almost done when suddenly the electricity went out... I disconnected the MacBook's hard drive and I wanted to turn on the MacPro but only the grey screen comes up with the apple logo and the spining circle.
What should I do?First try booting from your installer CD. If successful run Disk Utility to try to fix both the external drive and the internal macpro drive. Hopefully that will fix it.
