Apple mac not turning on
My MacBook is not turning on properly. its sounds like is starting up but thats is far as it gets. HELP??
What to do if your Mac won’t power on
First, try plugging in your Mac to allow the battery to charge. If it is not a portable Apple computer, skip this step. Wait a few minutes, and then try powering on the computer.
Next, try resetting your SMC.
Resetting the SMC of an Intel-based portable Mac with a battery you should not remove on your own
Note: This will not delete any data.
The SMC is responsible for controlling various system functions. None of your data will be deleted by resetting the SMC.
Shut down the computer by going to Apple () > Shut Down…
Select Shut Down or allow the computer to shut down automatically.
Plug in the MagSafe power adapter into a power source and then connect it to your Mac if you have not already done so.
On the built-in keyboard, press the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
Release the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
Then, try resetting your PRAM.
Resetting the NVRAM/PRAM
Note: This will not delete any data.
The NVRAM/PRAM stores information such as speaker volume, screen resolution, startup disk selection, and recent kernel panic information (if any). You should reset the NVRAM/PRAM if you experience issues relating to these functions.
Shut down the computer by going to Apple () > Shut Down…
Select Shut Down or allow the computer to shut down automatically.
Turn on the computer by pressing the Power Button.
On the built-in keyboard, press and hold the Command (⌘), Option (⌥), P, and R keys before the gray screen appears.
Continue to hold down the keys until the computer restarts and you hear the startup chime for the second time.
Release the keys on the built-in keyboard.
Then, try repairing the disk permissions using Disk Utility.
Repairing a disk’s permissions using Disk Utility on the Recovery HD.
Note: This should not delete any information or files from the disk.
Repairing a disk's permissions can help solve various file-related issues.
To begin, make sure your external disk that you are repairing is connected to the computer. If you are repairing an internal disk, skip this step.
Make sure the computer is powered off before continuing.
Press the Power Button to turn on the computer.
Press and hold both the R and Command (⌘) keys on the keyboard until the Recovery partition loads. If this does not work, shut down the computer, press the Power Button to turn on the computer, and then hold in the Alt (⌥) button immediately after you press the power button. Then, select the Recovery HD partition to boot up in the Recovery HD partition.
Select Disk Utility.
Once you are in the Disk Utility app, select the external drive from the sidebar on the left.
Then, choose the Repair Disk Permissions button on the right.
If this does not solve your issues, you may have no choice but to reformat the drive using Disk Utility.
If that does not work, try reinstalling OS X but not erasing.
Reinstall OS X
Note: This will not erase any data on the disk. However, it is highly recommended that you create a backup before continuing.
Reinstalling OS X can solve various problems such as corrupt system files.
Shut down the computer by going to Apple () > Shut Down…
Select Shut Down or allow the computer to shut down automatically.
Plug in the MagSafe power adapter into a power source and then connect it to your Mac if you have not already done so.
Press the Power Button to turn on the computer.
Press and hold both the R and Command (⌘) keys on the keyboard until the Recovery partition loads.
Select Reinstall OS X and then choose Continue.
Follow the instructions.
Then, try erasing and reinstalling OS X.
Erase and Reinstall OS X
Note: This will delete all data on the disk. Back up important files before continuing.
Erasing and then reinstalling OS X can give you a fresh start, making your computer exactly as it was whenever you received it from Apple. This can solve various problems such as corrupt system files.
Shut down the computer by going to Apple () > Shut Down…
Select Shut Down or allow the computer to shut down automatically.
Plug in the MagSafe power adapter into a power source and then connect it to your Mac if you have not already done so.
Press the Power Button to turn on the computer.
Press and hold both the R and Command (⌘) keys on the keyboard until the Recovery partition loads. If this does not work, shut down the computer, press the Power Button to turn on the computer, and then hold in the Alt (⌥) button immediately after you press the power button. Then, select the Recovery HD partition to boot up in the Recovery HD partition.
Select Disk Utility and then choose Continue.
Select your startup disk (Macintosh HD by default) from the left.
Select the Erase tab.
Choose the Format pop-up menu and choose Mac OS Extended (Journaled), enter a name for your disk, and then click Erase.
After the disk is erased, choose Disk Utility > Quit Disk Utility.
Select Reinstall OS X and then choose Continue.
Follow the instructions.
I hope I helped.

Power Outage - Apple Cinema Not Turning On
Hello,
We had a power outage and after electricity came back I tried to turn on my computer. The G4 starts but somehow my Apple Cinema does not come on (the light does not turn on).
Any suggestions what I should do to fix it?
Thank you in advance for your help.

G4 Mac OS X (10.4.4)Unplug the USB and firewire connectors on your monitor cable from the G4. Cycle the power on your computer and hit the power button on your monitor. I think it will now work fine, but it will require you to shut it off/on, like you would for other monitors.
Works for me. The G4/G5 uses the USB port as the communication link to the monitor to turn it off or on. Take this link out of the loop and the display will work fine, but it will now require your manual control. Take a look at the preferences for the display. With the USB cable plugged in, the options tab is seen. Disconnect the USB and the tab is not there (after a reboot). Hence the USB is more than an extension cord to your monitor sockets, its a remote control for the monitor. Note... Apple care has no knowledge of this. I figured it out by unpluging cables and what'ya know, the monitor came to life!

I have had and currently do have a similar problem
with my G4 and Cinema HD display; the power goes out
and the display does not go on.
Typically I have simply had to unplug the Power
Adapter, Firewire, and USB cables, wait a few minute
and plug it back in and the Cinema display’s light
comes on , as well as the display. However as of
yesterday this trick does not work. The G4 does work
with my old Sony display so does this suggest that
the video card in the G4 is OK? Could the 90w Power
adaptor be the problem?
Ideas?
Thank you

How to identify MacBook models -
The other night I was watching TV and heard a funny noise, then all of a sudden my power went out. The next morning I checked my TV to make sure the power was back on, and it was. Yesterday I went to turn on my Mac, but it wouldn't turn on, so I checked all the plugs, changed plugs, and changed power strips. Nothing worked. I have power surge protection, so not sure why my Mac is not working. I think maybe it has blown out but I've only had this Mac for almost 5 years and have taken good care of it, and don't think it should've done this. Is there any reasoning why my Mac won't turn on?
I'm not sure, my tv and computer are next to each other and it sounded like the noise came from around there, but when I first heard it I thought it was my sister's car. My tv and everything else works now, it's just my computer that doesn't.

Mac not turning on and overheated
My MacBook is overheated and isn't turning on, it started when I put my iphone charger into it and it had warned me that it was taking too much power and to disconnect because it would cause damage, I ignored this then my laptop switched off and hasn't turned on since, is this temporary? Please Reply if you can help
If a SMC reset does not bring back life to the MBP, make an appointment at an Apple store genius bar for a free evaluation. Make certain that the MBP is 'cool' when you try.

Why is Apple Mac not a popular gaming platform?
With all the advanced features Mac have .Why it is not a popular gaming platform ?
Macs are indeed popular gaming platforms, as evidenced by the many games available for them. Macs are not as popular as Windows system for gaming, particularly games that involve high levels of animation, because Macs don't have the ultra-high-performance graphics cards many gamers demand, though in many cases those cards don't really add anything other than status and bragging rights for the user. Many dedicated gamers also prefer to build up their own systems, choosing all the parts to suit themselves, something obviously not possible with a Mac.

my new macbook air( 761-13", ios 10) suddendy shutdown today during copy of a dvd from external dvdrom. and it does not turn on or start up.what should i do?
Hello kanani-2014,
After reviewing your post, I have located an article that can help with your Mac not turning on. It contains a number of troubleshooting steps and helpful advice for the issue you are experiencing:
Troubleshooting: My computer won't turn on
Resolution
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).

How instal developer (forms and reports ) on Apple Mac
I want to install oracle 6i forms and report on Apple Mac note book. how i and where i can download developer installer for MAC OS.
ThanksApple Mac is not a suitable platform to install oracle products. You can take a look at the Oracle Certify Matrix and you can build up your own conclusions.
In this case, use your Apple Mac for documentation, get a Microsoft Windows Based platform, and choose a certified platform.

Is there a built in reset on an iMac that will not start? Was plugged into a GFI protected plug, it triped. Reset GFI plug is working, but can not turn on my iMAC
Paul's suggestion may work, but if the Hard Drive was writing when the power was cut abruptly, there may be data corruption, file index corruption or even physical damage to the drive as the read/write heads clash.
If the SMC reset doesn't work, first see if the installation DVD can be inserted. If it can, start up with the C key held down. OK the language screen, ignore the installer and select the Utilities menu at the top of the screen, open Disk Utility. Select the HD in te left pane and click repair (not repair permissions).
If you get a message that repairs were carried out, run the repair again until you either get "the volume xxxxx appears to be OK" or a message that repair can't be carried out.
If it won't boot to the disc, or the disc can't be inserted, try a single-user mode boot - hold down ⌘ and S on start up until the Unix prompt appears.
Type carefully this command
fsck -fy
then press return.
As before, if the prompt reappears with the message that repairs were carried out, run the check again until you either get "the volume xxxxx appears to be OK" or a message that repair can't be carried out (and assume the latter if it hasn't given an OK within 4 tries).
Type
reboot
and press return to attempt to start up normally.
If it still won't start, it's fair to say the HD is dead. -
Can't use Find My Friends on iPhone due to Apple ID not being verified.
Can't do this as I can't access my .mac email any longer and I can not change the primary e-mail address for my Apple ID!
So my options are:
Create a new Apple ID, use that and lose all the apps I've purhcased with it (a fairly substantial amount)
Somehow Migrate these purchases over to a new Apple ID
Apple let me change the primary ID for the account
Anyone else ran into this before?
I've tried accessing the mail through a mail application using the correct server information, and trying both the old 6 character password and the one I had to change it too after they updated the security guidelines - neither work.
Help would be greatly appreciated as I can see more services down the line not working without the address being verified!To change the iCloud ID you have to go to Settings>iCloud, tap Delete Account, provide the password for the old ID when prompted to turn off Find My iDevice, then sign back in with the ID you wish to use. When you do this you may find that the password for your old ID isn't accepted. If this should happen, and if your old ID is an earlier version of your current ID, you need to temporarily recreate your old ID by going to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You should not need to verify the old email address. You can now use your current password to turn off Find My iDevice on your device, even though it prompts you for the password for your old account ID. Then save any photo stream photos that you wish to keep to your camera roll. When finished go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

Power Mac G4 not turning on after clean shutdown, works otherwise.
My Power Mac G4 does not turn back on after a clean shutdown, but turns on after being disconnected from the power. If I shut it down cleanly (Apple menu -> Shutdown), it shuts down, but then the power button does not work. After unplugging the computer and plugging it back in, the computer is able to power on successfully. I have reset the PRAM and have reseated the PSU connector.
I am using Mac OS X Tiger 10.4.11, but the same problem occurs under Mac OS X Leopard 10.5.8. I don't think the operating system really matters with this type of issue though, because the power button literally will not respond until I unplug and replug the computer.
Any suggestions?

I cannot log in to a MAC 10.5.8 and File Vault was NOT turned on.
Dear Mac Experts:
I know that there are many pages of information about using, remembering and managing passwords. I have read most of them.I know the passwords and File Vault was not on. I am working at someone's home on their computer and running their business. The computer is running MAC 10.5.8 and I don't know if it can be updated. The computer had an Admin account and no user accounts. I tried to change this so the compuer would be secure but my client did not want to. When I left yesterday the computer was fine. When I came in today there were a number of apps hanging. I forced quit Firefox and some other apps and logged out an shut down the computer. When I tried to log into the Admin Account which is the main user account I got the error messages below:
Your FileVault-protected home folder did not open and needs to be repaired.
click ok to repair the folder and continue logging in.
I clicked ok
then I got a new error message:
You are unable to log in to the user account "x" at this time because and error occured.
Clicked OK
File Vault was not turned on at anytime that I know of in the last couple of months. I luckily had a guest user set up and logged in as guest. In order to create another Admin account I had to use the password for the initial Admin main user account which unlocked the preferences pane and allowed me to create a new Admin Account.
Checked that FileVault was turned off.
After reading all of your comments and suggestions for the last 2 hours my head is spinning.
I don't know unix or type commands. I don't know where the install discs are.
As the new Admin I went into the keychain files and tried to verify and repair the original Admin's info.
Here is what I got:
Verification started
Checking keychain configuration for Susan F (user ID=501)
Home directory is /Users/suero
Checked login keychain
Error: login keychain not found
Unable to get info for ~/Library/Keychains/login.keychain, reason: No such file or directory
Checked password for ~/Library/Keychains/login.keychain
Unable to verify password for ~/Library/Keychains/login.keychain (-25294)
Unable to read settings for ~/Library/Keychains/login.keychain (-25294)
Checked default keychain
Problems were found; you should choose the Repair option to fix them
Verification failed
Repair started
Checking keychain configuration for Susan F (user ID=501)
Home directory is /Users/suero
Checked login keychain
Error: login keychain not found
Warning: some problems were not fixed
Repair failed
The machine is backed up onto a lacie external hard drive every hour.
In addition, while I was poking around I found the following:
com.apple.kerberos.kdc certificate
not trusted
com.apple.systemdefault certificate
not trusted
Could there be some malware at work? What can I do to get her files, home directory and everything back?
Thank you in advance for your patience with an old OS and a MAC user who does't feel comfortable mucking around under the hood.

I don't suspect Malware yet, Id guess Disk corruption or failing Hard Drive with Files not found.
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward. -
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.
