Mac Pro starts up to black screen

My 2 year old MacBook Pro will not go past the grey apple, loading bar grey screen. Every time I attempt to start my computer up, after the grey screen, the screen goes black. I've attempted to go to recovery mode, my mouse works, however I am unable to select the recovery mode options. I also attempted to restart in safety mode, but it fails. Has anyone else experienced this?

Hey there missind33,
It sounds like your computer is not completing the startup sequence, even after performing a Safe Boot and booting to the Recovery Partition. I would start with these steps from the following article named:
Mac OS X: Gray screen appears during startup
http://support.apple.com/kb/ts2570
Disconnect, test peripheral devices and network cables
Note: "Peripheral devices" refers to external devices other than what came with your Mac, such as hard drives, printers, or hubs that you connect via a USB or FireWire cable.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Disconnect all peripheral devices such as external hard drives or printers (leave only the display, a keyboard, and mouse connected).
Disconnect any Ethernet cables.
Start up your Mac.
If you can start up this way, one or more of your peripheral devices (or installed software related to the device) is probably causing the gray screen issue. Connect one device, then restart your Mac to test for the issue. Repeat the process until you locate the device at issue. Make sure the device is powered if it needs to be to operate correctly. Check with the manufacturer of the device for support or possible software driver or firmware updates that may be available for the device. Try a different cable with the device if possible (such as a different USB or FireWire cable).
Note: If you have multiple peripheral devices and the issue only occurs when they are all connected, but not when each device is the only peripheral connected, see the Additional Information section below.
If you are using a desktop Mac with a third-party keyboard and/or mouse device, and the issue still occurs, try starting up with an Apple keyboard and mouse connected instead. Try starting with no keyboard and mouse connected, then connect them after start up. Also, try a different USB port on your Mac.
If the gray screen issue persists with no devices connected, go to the next section (with the peripherals still disconnected).
There is additional troubleshooting in the article to use if needed, and even if you come to a step that you have done already, I would do it again, after having done the steps that came before it.
Thank you for using Apple Support Communities.
Take care,
Sterling

Mac pro no boot sound, black screen and loud fans

Hi everyone,
I've had problems with my Mac for a while now. First of all, it indicated ram problems with 2 beeps. I later fixed this by moving and changing around modules. It was solved, but now a new problem. The Mac seems to turn on, making its iconic sound for startup, but the screen remains black. After about a half to one minute, the fans go crazy and I have to shut it off. I've tried a few things like holding shift or alt, but that doesn't work as it doesn't even display a white screen.
I need to know what to do and I don't really have the time to buy new parts right now. I'm really a windows based pc fixer by the way so I'm new to fixing macs.
Thanks in advance.

Ah OK, a PowerMac G5.
Have you blown the dust out lately?
Boot off your *original* G5 Install Disk while holding down Option/alt key to select AHT, then run the extended Apple Hardware Test.
If you're sure the RAM is good, try the Hair Dryer trick...

It can show on any G5, and even many other computers & electronic devices of the period.

I installed Mountain Lion and now some times when I start my mac it look with a black screen and white text. I'm really worry about it, can somebody help me?

I installed Mountain Lion in my IMac and now, some times, when I start up my mac it looks with a black screen and white text. I'm really worry about it, can somebody help me?

Don't worry, this is probably just Verbose Mode. It's perfectly harmless. If you're not specifically invoking it, than it's probably down to an unwanted setting in NVRAM. See this article on resetting NVRAM if it continues to bother you.

Start up to black screen 2011 15" macbook pro

start up to black screen 2011 15" macbook pro does the start up chime and apple screen, then to a black screen, mouse arrow is visible and keyboard lit. help please

I had the same issue with my Macbook Pro too. You can follow this steps below:
1. Shut the computer down by holding the power button for 10 seconds
2. Restart the computer and press shift at the same time until you see the progress bar start moving
3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
4. After a moment, you should see the spinning beach ball
5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).
Apparently it's an issue with an automatic update that never quite got past the login screen.
Hope this helps!

Why does my mac sometimes start with a black and white fizzy screen at times? Should i be concerned?

Why does my mac sometimes start with a black and white fizzy screen at times? Should i be concerned?

Nope, not ever. Take it in for service.

My Mac Pro starts up when I turn on the power, BEFORE I switch it on with the button, why? Plus, my computer keeps freezing and blacking out.

My Mac Pro starts up when I turn on the power supply (when I plug it to the outlet), BEFORE I switch on the button on the computer, why is this happening? Plus, my computer keeps freezing and blacking out and I'm forced to restart it, that's when the compter starts on its own when I turn on the power.

Hello Engender,
I should have followed up with a progress report because I eventually eliminated all the problems I was having with my Mac Pro, now it's behaving like a new computer… beautifully. I did originally take Grant's advice above, changing the setting that I had in the System Preferences > Energy Saver but that only stopped from rebooting on its own when I shut down my Mac properly. Otherwise it continued to restart on its own after freezing or crushing when I switched on the power. I took my machine to the Apple Store and after many tests they couldn't find anything wrong with it. I was very depressed about the whole business.
It was after going onto many of the other Apple related websites that I discovered that it wasn't a faulty power switch or fan, as as I originally thought, but found out that my problem was related to the Graphic Card and possibly I did not have enough ram (I had the original amount of 2 GB). The original card that came with the computer: 512 MB ATI Radeon X1900 XT was over heating and forcing my machine to shut down, I think it was because I had upgraded to OSX Lion which on its own requires at least 2 GB of ram to operate well. I added 4 GB of Ram to the 2GB I had (4GB kit (2GBx2), Apple 240-pin FBDIMM, DDR2 PC2-5300 upgrades for Apple Mac Pro (4-core) 1st Gen. - 2006-2007 Desktop/PC, CT579443 from Crucial.com about $160 for the set) and replaced the Graphic Card with ATI Radeon HD 5770 1024 MB from Apple (around $260), (ATI Radeon HD 5770 Graphics Upgrade Kit for Mac Pro (Mid 2010) - Apple Store (U.S.)) This card works very well with my original Mac Pro 2008. I installed it about two weeks ago and no problem with it starting on its own, over heating or freezing. OSX Lion works well and I'm thinking of upgrading to Mountain Lion once I learn that my Mac Pro 1.1 will work with the new hardware I installed.
Your problem could just be the power cord but I agree with you that doesn't sound right, when I mentioned faulty switch I meant the part where the power cord meets the power button, the unit which houses the power distribution, I thought at first that it could be faulty but changed my mind because of the computer overheating.
I don't know if this is of any help to you but I hope your trouble will be solved with the new cord.

My early 2008 Macbook Pro is suffering from black screen after Yosemite update

My early 2008 Macbook Pro is suffering from black screen after Yosemite update. It ran beta 5 great but failed on restart after beta 6 install. There is no cursor but I can hear the HDD spooling up. I have tried booting in safe mode, PRAM reset and SMC reset but nothing works. After the first 5 days of every now and then trying to start it, it started fine. I used the machine all day with no problems, it had rolled back the install and was back on beta 5. I decided to try the update again, the same thing happened and it has stayed black for over a week now. It wont work with a monitor either. Help!

Hello Adam,
I would try instead of installing the beta software, to install the official build of OS X Yosemite from the Mac App Store to see if that gets you passed the no video issue when updating the beta software.

Mac pro start up trouble , 5 important questions!!

I went on a 2 week holiday where my mac pro dual core was unplugged. When I got back and started the system it would go to the desktop screen but would then either freeze or I would get red lines across the display. I would have to manually shut it down and restart till it worked normally.
So far I have reset the SMC, the PRAM/Nvram, I have replaced the computer battery, run Norton Anitvirus, run a apple Hardware test (it came back fine) I have run Disk Warrior and Tech Tools Pro 5 and I have done an OS X archive and install and nothing has changed.
Although today the first 2 times I turned it on there was no start up chime/black screen and it took 5 manual restarts to work!
Question 1: Should I do a fresh install?
Question 2: Trouble with the first question is that my Super Duper copy was made after the problem started - won't the problem just be transferred?
Question 3: Does migration assistant transfer my copy to my hard drive if I do a fresh install?
Question 4: What should I do? - Should I pay for it to be fixed?
Any help is appreciated!!

Thank you for the reply.
Can I ask a few questions as I'm slightly new to computers. I didn't quite get the freshly formatted new drive stuff.
In my mac pro I have the mac hd with an additional hd and I have one external drive which is my backup (I need to get another one).
Q1. Unfortunately my backup was made after way the trouble started so a fresh install and migrate won't help will it?
Q2. Because of this I was thinking of doing a fresh install then just transferring over the music and photos and downloading the software again - would this help?
Q3. Because of this, I own final cut studio 2 which was then stolen from me, can I just transfer this from my backup (if so how?)
Q4. How come you recommend uninstalling Norton Anti Virus?
Q5. If I do a fresh install should I remove my second hd until its done?
I tried the overnight trick with no luck.
Thanking you in advance

On startup Mac Pro I get a blue screen and a cursor on the upper left. The mouse cursor shows up independently. Is it likely a video card failure?

On startup Mac Pro I get a blue screen and a cursor on the upper left. The mouse cursor shows up independently. Is it likely a video card failure?

I managed to boot the computer and get the desktop to show. I now have a "repaired" computer. There are several problems that have cropped up. One is that I can only start up now in Safe Boot mode. Is there a way to turn it off? Also, I do not have a sound list, so I can't access anything requiring audio. Google Chrome only shows up as a white screen. Pictures that loaded before don't load in browsers, etc. Any suggestions? I figure I should reinstall Mac OS Lion for starts, maybe even do a mirror backup and reformat the drive. I think this drive has turned into scrambled eggs...what a headache!

orshikhfromsc,
boot from the Mac OS X Install DVD that originally came in the box with your MacBook Pro (by holding down the C key as it starts up). When the desktop appears, select Disk Utility from the Utilities menu and erase your internal disk. After it’s been erased, reformat it. After it’s been reformatted, exit Disk Utility and reïnstall the version of Mac OS X from that DVD onto your internal disk. After that version of Mac OS X has been reïnstalled, boot from your internal disk and run Software Update to get it up-to-date within that version; that should allow you to redownload and reïnstall Mavericks, if desired. If Mavericks is reïnstalled, run Software Update again to get it up to date.
If you no longer have the two grey installation DVDs, you can purchase a replacement set from either Apple or iFixit.

MacBook trying to Install Windows XPSP3 disk.

I too am having the same problem. I do not know about the host of this thread, but I have been using a brick and mortar version of XP SP2 stand alone so it is not bundled with a computer like Dell, HP, etc.
I have run it before just fine but it was time to reformat the drive, 0'd everything out, reinstalled 10.5.2, upgraded everything, repaired permissions and them ran Boot Camp. Put in the XP disc and all I get is the flashing dash mark in the upper left hand corner. I actually have 2 legal versions of XP SP2 stand alone and the same result on both discs so it has to be something with the partioning? I also redid the partitioning at various sizes all with the same effect. No luck.
Any new thoughts anyone?

If you replaced the Ram in your machine at any time, you may not have been aware of the fact that Apple computers have always been a little picky when it comes to 3rd party Ram. Apple computers have always run very well on 2 different brands.

The only difference I am aware of is that Crucial offers a download and will tell you exactly what Ram your computer is capable of using and the prices that are available.

My ipod touch 2g 32GB is not starting, just a black screen.....

Hi friends and experts,
I need your help, since yesterday my Ipod 2G 32GB is not starting, only a black screen.

I also tried to hold the both buttons Start and Home button for 30 seconds etc....nothing happend...so I need your useful and helpful tips to start my Ipod...I don't no what should I do that it starts again..
with very best regards

Hi,
Try connecting your iPod to your computer and letting it charge. It will take a while for iTunes to recognize it, if it is dead. Once iTunes recognizes your iPod, try resetting it again.
Hope this helps!
