Mac only starts up in OS X Utilities

I just recently downloaded OS X Yosemite, however was really laggy afterwards, so I decided to try and re install a new copy of the OS X by using disk utilities. When it was complete it only brought me back to the OS X Utilities and continues to .Also tried to use the other option of "restore from time machine backup" and there is nothing that pops up for it to restore. Any suggestions or help will be greatly appreciated. Thanks!
P.S. Its 2012 Macpro

Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

My Mac keeps starting up to the disk utilities screen. Im guessing i need to repair the disk or load my backed up memory but i am unsure of how to do that. I have all my memory backed up on an external hard drive.

The Disk Utility screen has instructions right on it.
Just read them and follow the directions.
Readers can help if you get stuck.
It opens with something like, "select a disk, volume, or image".
You click on your drive in the left column, top item.
The next screen spells out how to do a ( Repair Disk ).
You have a Macintosh. It will not cut your hand off.
If something dangerous is coming, it will say stuff like, "this will erase all the data on your drive. Do you want to proceed?"

E mac only starts up in safe boot

Having accidently pressed a few keys on the keyboard while not paying much attention to what was happening to my computer it just switched itself off!!! (I think it was the F15 button that was pressed!) Now it only starts in safe mode and I can't get many of the applications to work, internet connection to name one. How can i get it to start in normal mode again?
Can anyone shed some light on what I've stupidly done and how can I solve it please?
Thanking you in anticipation

wim,
Welcome to the Apple Discussions!
Do you mean the Mac always starts up in Safe Mode, without you pressing the shift key? You could try starting with the keyboard disconnected to see if it starts normally. If that's the case, check that the shift keys on your keyboard aren't stuck. You can jiggle the keys, or carefully pry them up and check for anything gumming the key post contact (keyboard keys pry off coming straight up and are replaced pressing straight down; on long keys such as the spacebar, shift keys, and Enter key, there's a wire spring that needs to be folded into the clips underneath).

Macbook only starts into Utilities menu after trying to restore

I recenty bought a macbook pro used off craigslist. I tried to system restore the computer. ( so i could start off with a fresh empty computer) I used disk utility to clear all the memory on the drives, then i proceded to click on the tab that says "install lion osx". Everything started working, but it required me to type in my apple id to complete the instalation. When i logged in it said that my account doesnt have lion bought on it, and i need to use an account that does. I have no clue on how to get lion operating system onto my account without physically logging into my computer and buying it. But since my computer will only start up into the Mac os x utilities menu im not able to buy it.
Help!!!
I want to to a complte system restore

Drive Preparation and Installation
1. 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.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. After formatting is completed quit DU and return to the installer. Complete Snow Leopard installation.

Recently my mac has started making faint clicking noises just like a fan catching something as it spins round, it is only faint but i can notice it -any suggestions please

Recently my mac has started making faint clicking noises just like a fan catching against something, it is only faint but loud enough to hear. any suggestions please

While it could be a cooling fan, a noise like that is usually a sign of a dying hard drive. Back up everything immediately. Make immediate backups of any new documents you create after the full backup.

Data recovery house tainted my Mac-only files: help!

I sent a failed ext. FW drive (clicking sound, wouldn’t mount) to a fairly-well-known data recovery specialist that advertised PC and Mac formats. The drive contained numerous Mac-only files, including Sound Designer II audio files (.sd2), Final Cut Pro (.fcp), and Digital Performer files (native, no suffix), to name a few.
After said specialist started working on the drive, it became frighteningly apparent that they were not up to speed on Mac systems. To make a long story short, after a couple of weeks I received a hard drive formatted FAT32, and every Mac-only file showed up in Finder as a Unix Executable file.
My first thought was they were using Windows-based software and had corrupted all my Mac-only files beyond repair. Forging ahead and knowing nothing about scripts, I used a 3rd party program called Super Get Info and was able to change the Type and Author of the Digital Performer files, and got them to open. So far, so good. But changing the Type and Author of the .sd2 files didn’t yield the same results; Finder sees the type, size, etc. but no audio program (DP, Peak, Jam) will open them.
Thinking I was screwed, I opened another project in DP that contained audio files which were still recognized in Finder as Unix Executables, and they played! I have no idea why this works---no other program will open them independently---but it shows if I can get an app to recognize them, they are still valid files.
Is there a way to dig deeper, besides just changing the Type and Author, to essentially get back all the header(?) information that was originally there in the .sd2 files (before the "data recovery") so an audio program can see that these are indeed valid files and legit to operate on? Something in Developer Tools, 3rd party, etc.?
Thanks,
Roger

Extern firewire drives often come formatted as FAT32 - so unless you reformatted it yourself that may have been the way it was. When Mactintosh files are saved to a FAT32 file system, the resource information is written to a file with a ._ added to the front of the file name. If you go to a terminal window and cd to your extern drive, "ls -A" will show if the resource information is there. For a file call "file.s2d", you should see a hidden file call "._file.s2d". Some utilites have trouble creating resource forks on FAT32 drives - so your utility may not be working. Try moving some of your files back to your main drive and correct the Creator and file type there - may be that will work.

IBook G4 can only start up from CD

Hello everyone,
I have a friend who has a problem, his iBook G4 can only start from CD and never from HD. Is there a way to solve this problem for him.
Thanks

Does your friend have Mac OS X 10.3 or 10.4? If you can startup from the install CD, can you open the Disk Utility (from the "Installer" menu in Mac OS X 10.3 or from the "Utilities" menu in Mac OS X 10.4)? Does the hard drive appear as an option in the Disk Utility? If so, you should try to "repair disk" from the Disk Utility. Are there any errors found? Can the Disk Utility repair them?
If it repairs the errors, you can quit the Disk Utility and then Quit the Installer. The computer will restart back to the hard drive.
If the Disk Utility can't repair the errors, you may want to invest in a more powerful utility like .
If the hard drive does not appear as an option in the Disk Utility, it may be damaged beyond software repairs. You might find the Apple Hardware Test CD (which could be the same disk as the Mac OS X installer) and run the extended tests.

Mac OSX Start up disk

I have a message " Your Mac OSX start up disk has no more space available for application memory" Yet I have only used 20% of my 500gb capacity. Any help would be appreciated, pse.

Welcome to Apple Support Communities
That message tells you that you don't have enough RAM for applications. Open Activity Monitor (in /Applications/Utilities) and see which applications are taking RAM, and tell us which they are.
You will probably need more RAM. You can buy more RAM at OWC or Crucial > http://www.macsales.com

Mac cannot start up Yosemite

hi
i have a Mac with Yosemite, is taking more than an hour to start up, the bar before request login takes an hour and the login window does not show up
i have Yosemite
help !

You could try & see if the computer may eventually start into
Safe Mode or Safe Boot, where you'd hold the Shift key down
for a long time just after startup, and until there is evidence of
the Finder window appearing. Sometimes this can take up to
15 to 10 minutes, depending on several factors.
•OS X: What is Safe Boot, Safe Mode? - Apple Support
Once into the system, other tests and perhaps Console error
logs from the System could be viewed. You could also try &
see if Disk Utility could repair permissions or repair disk, once
you have the computer running. You may be able to start up
into OS X Utilities on the Recovery mode, to check/repair HDD.
If you get as far as a Gray Screen, and no further, this may help:
•Mac OS X: Gray screen appears during startup - Apple Support
•OS X: About OS X Recovery - Apple Support
More complex & advanced methods of attempting to diagnose & repair
issues on startup can be rather involved and some of the methods do
require a high or greater degree of understanding the Terminal or the
command-line access to the underpinnings of OS X. This goes behind
the scenes where the user interface is not simple or user-friendly...
For those who have read & carefully tried the command line access
and not cause more damage, once learned it can be helpful & direct.
•Mac OS X: How to start up in single-user or verbose mode - Apple Support
Use of command line and Terminal access is not recommended in
general by those who have a problem and only one computer to
learn how to use it; you may have a worse situation due to lack
of experience. So other methods less invasive (disk utility) are the
recommended path; or if problems point to hardware cause, then
the computer would best be taken to an Apple Specialist or genius.
•Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support
So if you can access the computer to get the basic report mentioned
in the above post (etrecheck) that may show someone some clues as
to what may be wrong. However a command line report such as that
which uses terminal commands, is good if read through by someone
who understands what the cryptic details mean.
Hopefully you can post more information because there are several
things that may contribute to your computer's symptoms...
To troubleshoot involves attempting several things to see what works
when working in the blind on resolving problems by rote. However if
you haven't experience in the Terminal or command-line, tread careful.
Good luck & happy computing!

Only starting in safe mode

Hi there
I have an imac 8.1 that will only start in safe mode.When it does start it runs very slowly and I can't see a mouse pointer, so navigating around is a bit of an issue.
I have reset the all the PRAM and the like, I have even swapped out the hard drive thinking that was the issue. So with a totally new install I am still getting the issue (so my mind is thinking some hardware isn't playing nicely). The problem initially happened after I had updated to Maverick, but it is still continuing on Snow Lepord and Mountain Lion when I have installed those as well. I can't get to install Maverick as it doesn't want to install while in safe mode.
I have got to the log files and managed to see a number of panic listed (as you can imagine getting them up on screen is an effort with no mouse). The main panic seems to be over:
Kernal Extensions in backtrace:
     com.apple.GeForce(8.1)[<<some GUID>>]@<<some memory reference>>
     dependancy: com.apple.NVDAResman(8.1.0)[<<some GUID>>]@<<some memory reference>>
     dependancy: com.apple.iokit.IONDRVSupport(2.3.7)[<<some GUID>>]@<<some memory reference>>
     dependancy: com.apple.iokit.IOPCIFamily(2.7.3)[<<some GUID>>]@<<some memory reference>>
     dependancy: com.apple.iokit.IOGraphicsFamily(2.3.7)[<<some GUID>>]@<<some memory reference>>
BSD process name corresponding to current thread: WindowServer
Mac OS version
12D78
Etc etc etc
last loaded kext at:<<number>> com.apple.driver.AppleHWSensor 1.9.5d0
So my thinking is it's the 8800GS graphics card at fault in some way. I have read a few horror stories, but I don't think I am having the same issue as it is powering up fine in safe mode at a high resolution (if a bit flickery).
Any ideas?
Cheers in advance
Garf

I have it working now.
I found the following
Issue: System stops on Kernel Panic during boot.
Solution:This is caused by the GeForce Kexts that are installed by default. The issue is resolved by removing the GeForce kexts at boot, and it can be done as followed:
rm -rf /System/Library/Extensions/GeForce.kext
rm -rf /System/Library/Extensions/Ge*.kext
rm -rf /System/Library/Extensions/NV*kext
And it seems to be "Ok" has a bit of a shout when I first came back in

New Intel Mac Mini Start-up Problems

I've recently purchased a new Intel Mac Mini (my first Mac after switching from a PC). Several times (probably once a day), the mac mini won't start-up.
I've noticed it happens after I've used iPhoto or iDVD. The mini becomes busy and performance seems to slow. After the software has finished its task, I can exit the application fine and shut down the mini.
When I then go to boot the mini, the little blue light comes up, but nothing else happens. It's almost as though it's in sleep mode (which it isn't). I've tried different ways to wake it using the keyboard, mouse and start button, but nothing.
The Mac Mini will only start-up again if it is unplugged from the mains and left for several minutes.
Has anyone else had this problem? Is there something I'm doing wrong that my lack of Mac knowledge may not be aware of?
Any help would be appreciated.
Thanks

I have been frustrated by the same issue. My (admittedly non-professional) diagnosis is that the problem is related to heat build up. I am able to boot normally only after forcing a hard shut down and waiting for "a while" (5 minutes is not enough, 30 minutes does the trick). Thus my hypothesis that an appropriate cooling down period is needed.
Any similar thoughts? I'm calling Apple today...
