What is the problem exactly???
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...

Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab of Activity Monitor, are there a lot of Pageouts?

Mac Mini blank white screen. Did Cmd+R reprograms but doesn't leave the white screen!!

Mac Mini blank white screen. Did Cmd+R but doesn't leave the white screen! I tried Cmd+Option+R, this allows reprogramming but after 34 or so minutes it remains in the white screen! Any ideas?

Unfortunately, the white screen will not go away! Therefore, I do not have the option to the Disk Utility!! I wish I could! I would have already erased the disk and reinstalled the OS. Side note here is that an Apple Fan told me that she and her husband had a similar scenario with a new iMac!! Turned out (after 3 attempts by Apple Techs to fix) to have to replace it! They related to me that there was an issue with the connections between the Logic Board and the Hard Drive! The hard drive got burnt out and so did the Logic board on different occasions. I have been a PC user for years until I got tired of all the maintenance and wanted to try Mac. So many thrilled fans claiming they never get issues as often as a PC. Well, here I am six weeks after buying the Mac Mini having issues...I guess a machine is a machine, is a machine! I was thrilled with the Lion OS and all the interaction I was having with it! I truly thought that this was a highly superior computer. I expected quality control to have equally a superiority that one would expect from an Apple product. It could be that this unit is a lemon! It happens! Because I also have iPad and iPhone that have given me the best performance ever!! So I hope that I will someday see the same from this Mac Mini that is just over 40 days old!
If you know another way to get thru the white screen to get to the Disk Utility...I would love to try it. In any case, I am waiting for a call back to confirm an appointment date and time to visit a Mac store for repair.

HT4759 I wanted to login to iCloud from my ipad to view my calendar. The message was that I needed to set up iCloud on the device but I have and it won't give me the login screen. What am I missing? Thank you.

I'm assuming you are trying to log in using Safari on your ipad - if this is the case, you can't do that on an iOS device. You must use the Calendar app on the device. If you are using someone else's device, then you have a problem doing this. I just tried using Chrome on an iPad and that also doesn't work. If there's on nearby, use a computer's browser, that works.

Pull down View > Show Sidebar. This will give you back the same functionality of iTunes 10.x.x.

No, I don't think that you can

Could you specify the model of MacBook and the OS X it's running, please? Some of the advice or references vary along with the system, so this could be helpful to formulate a reply. I've never used a Guest User selection, but do have more than one User.
If the computer does not have an optical drive, you may be able to boot it into a recovery disk mode or something; in an attempt to see what is wrong and maybe fix it.
Good luck & happy computing!

My MacBook Pro has been having difficulties at startup. It sometimes locks and doesn't get past the white screen. It has also locked up several times and gotten a green stripes across the entire screen. What is causing this and how do I fix it?

You don't, take it to Apple for repair.
This might interest you if it's too old to fix.
My computer is not working, is my personal data lost?

My computer won't turn on, it just stays on the blue screen, whats wrong?

This has happened before, but the problem was supposed to go away. A window pops up randomly and says "start-up disk is full" and i just click "OK" and move on. But then today i turned off my computer and about 30mins. later I turned it back on and it got stuck on the blue screen. WHAT DO I DO?????

Reboot holding the Shift Key down and target some large files like Movies to copy to a external storage drive, then delete them from the boot drive and reboot a couple of times so OS X realizes there is new space available and boots normally again.
See #7 here
Step by Step to fix your Mac
See "Storage drive" here

If that doesn't work then do this
Create a data recovery, undelete boot drive

Reinstall OS X using one of the following. The first is for Snow Leopard and the later for Lion/Mountain Lion.
Reinstall Snow Leopard without erasing the drive
1. Repair the Hard Drive and Permissions
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. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main 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.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion 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.

My iPad is disabled and I can not input my passcode. what do i need to do? I tried to connect to iTunes, but it will not allow me to connect via compute USB as I cannot input my passcode for the iPad.

You may need to put the iPad into recovery mode : http://support.apple.com/kb/ht1808 - you should then be able to reset the iPad and restore/re-sync your content to it

My mac is running slowly and it start by itself on the safe mode. What can i do to resolve this?

I would like to know how can i resolve this

Try what you missed here:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

HT3964 my mac comes on but stays at the white screen with the apple on it, what should i do?

white screen with apple loading?

restart the computer and hold the left shift key until the apple logo appears. This will (attempt) to start the computer in Safe Mode. Safe Mode performs a disk directory check and repairs the drive if necessary, starts the computer with a reduced set of drivers (so some things may not work, such as your printer), and deletes the temporary caches. Since part of what Safe Mode does is repair work, you can attempt to restart the computer normally if it successfully boots with Safe Mode.
If this doesn't work, let us know.

I am running Firefox 3.6 on mac 10.6.2 and all I get is a blank white screen. Have reinstalled, nothing is working. Thanks

Looked at other forums, updated flash. Not sure if this is a bug or if something got corrupted. There are other answers suggesting profiles, extensions, add-ons. Honestly I'm a bit lost.

This can be a problem with the file places.sqlite that stores the bookmarks and the history.
