At Startup Making Me Login? I've never had to login

Hello everyone,
Yesterday evening my mac froze so I had to restart. When it finished booting up, on the screen it asked me to enter my password. I've never set up my mac to have to login, so I exhausted all the passwords I could think of and still no access to my computer. On top of the my name it displays the time and date, serial number, OS 10.4.11, build # and "No system adminstrator"?
Is this some security measure but how can I crack my own computer? It started when I was trying to back up my hard drive with the new Western Digital external My Book 500gb I just bought.
Can anyone give me advice on how to login? I just want to retrieve my files and dont mind reinstalling with my OS 10.4 disc. Any advice appreciated.
thanks

First off, boot off the Install DVD and use Disk Utility (in Utilities menu when running off the DVD) to Repair Disk. Repeat if necessary until no errors appear. Then try to reboot and see if all is Ok.
Recovering the login password can be done with the appropiate utility after repairing the disk (same Utilities menu); however, if it fails to recognize at least one of the user accounts as Admin, that can be a problem.
If you don't have the time to do O.S. resuscitation, you could split up your external drive into several partitions, install Tiger on one of them, use [Carbon Copy Cloner|http://www.bombich.com/software/ccc.html] or [Super Duper|http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html] to clone the damaged internal HDD to another partition, then do an Archive and Install and hope that it recovers the Admin-enabled user account. If that doesn't work, you'll have to do a full Erase and Install and recover what you can from the cloned backup of the dead system.

Ive never had any problems with my MacBook pro, but turned it off last night, now it won't turn on again...HELP!

so like it says, ive never had an issue. and now it won't turn on. it's plugged in to charge, and the light is green, as usual. I don't know what's happened, is there a way to turn it on at all? or am I going to have to take it into apple?

The Mac is inherently a Multi-User system, even if you are the only one who ever used it.
This means that System Directories are kept almost entirely unmodified, and all of YOUR files, including things that seem like "system-wide" preferences, are all kept under /Users/Your login/ in your private directory.
I recommend you re-install Mac OS X. That should restore any parts of the System you discarded by accident. Your files should remain untouched throughout the entire process, PROVIDED you have no pre-existing Directory damage.
If you are running 10.7 or later, hold down Command-R at startup, which will take you to Recovery_HD, and use Disk Utility to (Repair Disk). Run it again until it is stuck or finds no more errors.
Then re-download and re-install Mac OS X.
You should not need to do a "clean Install" [where one copies off all User files onto two Backups, erases the drive, and installs on a clean drive]. Any part of Mac OS X that was missing or damaged will be replaced by a fresh copy.

I have an older iMAC that once burned CD's with no issues. Now I get an error message saying "The attempt to burn a disc failed. The device is not accessible, probably because it was removed". I have never had it touched so the device was not removed.Help

I have an olde iMac that once I have an older iMAC that once burned CD's with no issues. Now I get an error message saying "The attempt to burn a disc failed. The device is not accessible, probably because it was removed". I have never had it touched so the device was not removed. Please advise as to what could be the problem. How to fix. Thanks

Try resetting the SMC and PRAM first, if that doesn't help try a cleaning disc.....and then buy an inexpensive external burner. Slimline super drive failures are all too common.
To reset the SMC
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Mavericks update locked me out of my Macbook Air and insists on a keychain password to let me in.nto my computer at all because it keeps asking for a keychain password, and I've never had one.

I just updated Mavericks because I was unable to get Google Chromecast to work with my MacBook Air. When it rebooted it insisted on my entering my login keychain for every single program on the computer. I have no idea what a login keychain is, and my password doesn't work. I can't get past the opening page and my only options are to enter the login keychain, sleep, restart, or shutdown. What do I do?

Thanks. My problem is that I never had a keychain login password, and even if I did I can't get past the login, so I can't change my keychain password or delete keychains. All I can do are enter the keychain login or reboot, which puts me right back where I started.

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just canceling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.

My IPhone 6 with AT&T is dropping 5-10 calls a day. Calling from same location as my 5S which never had dropped calls. Is this a hardware or software issue?

My IPhone 6 128GB with current software using AT&T is dropping 5-10 calls a day. I am calling from an office with good signal strength and in the same location as i did with my 5S which almost never had dropped calls. Is this a hardware or software issue? Is this a common issue with the new IPhones?

Hi jackneedshelp,
Thanks for visiting Apple Support Communities.
If calls are not going through on your iPhone 6, I recommend going through the troubleshooting method found at this link:
iPhone: Troubleshooting issues making or receiving calls - Apple Support
These steps can help identify and resolve the symptom that might be causing the connection issue.
All the best,
Jeremy

When i plugged my ipod into the computer it started to make buzzing and screeching noises. It became hot so i removed it and then the screen froze while it continued to make these noises. I have never had anything like this happen. (never gotten it wet or had it exposed to extreme temperatures) It is also unresponsive to any buttons on the ipod and it didn't show up when i plugged it into my computer. What do I do? Also if it is unfixable could i get a free one from apple?

As described in the header, my Apple TV (120GB) has its LED blinking amber non-stop, no video, no audio. It is about 2 months old and I have never had issue with it before.

As described in the header, my Apple TV (40GB) has its LED blinking amber non-stop, no video, no audio. It is about 2 months old and I have never had issue with it before.

They stopped making that model four years ago. There is no way it is two months old. Trying connecting it to a computer with iTuens via a USB cable to see if you can re-install the firmware.

I'm trying to export a file as .dwg for Autocad but it's not showing the dwg preview and it appears to be saving as code (lots of gobbledegook when reopening the file). I'm on OS 10.5.8. Never had a problem with this before. What am I missing? Any idea

Frustratingly, since I upgraded to Yosemite 10.10, I too am having the worst problems with WiFi dropping out. I've never had this problem before on my iMac 27-inch mid 2011 model. Turning WiFi off and then back on again sometimes works. Help please.

Frustratingly, since I upgraded to Yosemite 10.10, I too am having the worst problems with WiFi dropping out. I've never had this problem before on my iMac 27-inch mid 2011 model. Turning WiFi off and then back on again sometimes works. Help please. I've already tried a lot of your suggested fixes, but without success. Why hasn't Apple Fixed this?

Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter tab, if there is one. Uncheck the box marked
Wake for Wi-Fi network access
if it's checked.
Step 5
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 6
In the Wi-Fi settings, select
Advanced... ▹ TCP/IP ▹ Configure IPv6: Link-local
Click OK and then Apply.
Step 7
Reset the System Management Controller.
Step 8
Reset the PRAM.
Step 9
Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
Step 10
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Why is iChat saying my screen name is not valid when I've never had a problem before?

All of a sudden, my iChat will not connect to my mac.com account. I keep receiving an error message that says "the screen name entered is not valid". I've never had an issue with this account before. I thought maybe this was because I just traveled abroad yesterday- however, I was successfully able to log into my iChat account when I first arrived, but when I went to login again, I started to receive that error message. I've used this account in the past when I've traveled abroad and never had an issue. Why all of a sudden? Help!

HI,
There does seem to be a glut of people who use their @Mac.com Screen Names in iChat or Message that travel to different countries that then find they cannot login
Try Logging in here https://settings.aim.com/
If it says your Account has been Suspended you will need this page
Use the TOSGeneral email to contact them.
It seems the people at AIM/AOL that contact you do not always know about the agreement that Apple Issued IDs (@mac.com and @me.com) are also valid AIM Screen Names.
They will
1) Want you to change the password (it will not make any difference to the Flagging of your "account")
2) tell you they can't find that you have an Account with them (you don't it is with Apple)
Remind them gently that there is an Agreement with Apple to allow Apple IDs as Valid Screen Names
That their Servers check the Names and Passwords with the Apple Servers but the Suspended Account Flag is set at their end and they need to Undo it.

Serious problems of late syncing... never had any issues until now

Updated all the latest software a few days ago. I am away from home on business, in a hotel room, and the way I keep my phone charged is plugged into my MBP overnight. It always works at home. Yes the MBP is plugged in. I wake up to find my iPhone at 20% power.
I unplug and plug it back it, it starts the sync, then my iPhone goes away (on the left side of iTunes) and the phone says "Sync in progress" but there is not syncing going on in iTunes, and the iPhone is no longer down the left hand side. I cancel sync on the iPhone, try again, same thing.
So I go to restore. It locks up the restore, while the iPhone says "RESTORING", iTunes stops and kicks the phone out of iTunes like during the sync.
I went through the steps to force the restore (holding home while plugging it in) and it wiped it fine, then I had a very difficult time getting it to backup the iPhone with an older backup. It overwrote my latest backup with a backup of no data, but I had one from September that was OK. Each time it tried to backup, same thing would happen, and phone would say "RESTORING" but iTunes would kick it out.
Tried restarting the computer, creating a new profile on the MBP, etc. What finally did it was just continually trying to force the backup, it finally kept the phone syncing and restored it properly.
Now when I got to plug 'er in to the MBP, it sees the phone, starts the sync, and then again kicks the phone out of iTunes and leaves "SYNC IN PROGRESS" on the iPhone. And of course it stops the charge process.
So *** did Apple do to iOS 4.2.1 or the new iTunes 10.1 (54) that totally botched the syncing process up?
For information, I have had this phone since January and have never had a single problem with it other then it locking up once a month after I got it and never since. It is an awesome phone, but this sync issue is beyond frustrating. The phone was not dropped, damaged or anything, and it has a hard case on it. Further, I had two different USB iPhone connectors that all do the same thing, in both USB ports on my MBP.
Thanks for any insight, hopefully Apple reads this. I am relatively computer savvy so I do not think this is OE.
Matt

Yes the MBP is plugged in. I wake up to find my iPhone at 20% power.
Is your MBP set to sleep automatically after a period of inactivity when connected to a power source?
So * did Apple do to iOS 4.2.1 or the new iTunes 10.1 (54) that totally botched the syncing process up?
Not sure. The syncing process has not been totally botched up or botched up in any way with my MBP and iPhone running the current iTunes version and iOS 4.2.1.
If the same occurs with a new computer login account and there is no change after downloading and re-installing the current iTunes version over the existing, there may be a problem with your iPhone.

I have never had the issues I am having with the latest update to Yosemite. Is there a fix/update for this?

I have never had the issues I am having with the latest update to Yosemite. Is there a fix/update for this?

For what? It works fine for me on three different computers. If you want a fix for something then be more specific.
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.
5. Reinstall Yosemite from Scratch:
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.
