Switch screens with keyboard

it's annoying to switch screens because i have to take control of the mouse to do it when hes usually doin something, so is there any way to switch back to my screen with the keyboard?

Do you mean "screens" as in Spaces or "windows" as in Finder or an application? For OS X shortcuts see Mac OS X keyboard shortcuts. For Spaces simply open its preference pane where you can see the currently assigned shortcut or assign your own.

E450 won't boot with key switch, does with keyboard

Evening chaps.
As the subject suggests, this is actually a follow up question to a previous thread by the same name.
I have a E450 here which until about 4 hours ago was running just fine using a serial console.
Up till then it has had no issues, problems, etc and has run absolutely flawlessly.
I did a nice graceful shutdown (Solaris 9), and then used the power-off from the obp.
I turned the key off, powered the machine off, switched some disks around and when it came to powering the unit back on ... it wouldn't!
No matter what I did, I could not bring it back to life.
The 'solution' was to plug a keyboard in and use the power key on that.
Now my question ... does anyone have any idea as to what causes this and how do I go about fixing it???
Having to have a keyboard attached to the machine to turn it on has knobs on it!
Any suggestions here would be greatly appreciated as this is a 'new' behaviour for this machine.

Try a reboot by holding both the power and home buttons until the apple logo appears, ignore the red slider if that appears. See if that clears the glitch.

After reading and resetting everything with Keyboard I still get blank white screen. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans at full speed.

After reading and resetting everything with Keyboard I still get blank white screen on 2nd? page of boot. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans run at full speed, machine boots then runs normal except the dvdrw will not . The mid 2011 IMAC had the same problem with LION. I changed hard drives, formatted, and installed a clean install of latest os x mavericks. Any help would be greatly appreciated.

Use the uninstaller provided with the Sophos software. You can uninstall CUDA via the preference pane. Be sure you remove the com.nvidia.CUDA extension which is located in the /System/Library/Extensions/ folder. Not sure if Fan Control has an uninstaller so you will have to do it manually:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper
    2. AppDelete
    3. Automaton
    4. Hazel
    5. AppCleaner
    6. CleanApp
    7. iTrash
    8. Amnesia
    9. Uninstaller
10. Spring Cleaning
For more information visit The XLab FAQs and read the FAQ on removing software.
Be sure to remove your two Login Items. Finally do this:
Reinstall Lion, Mountain Lion, or Mavericks without erasing 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
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
     Note: You will need an active Internet connection. I suggest using Ethernet
                 if possible because it is three times faster than wireless.

I am trying to switch laptops with my mom, and successfully wiped mine and restored it, but now her password won't allow her into my computer, even though it says it's her account. Is there any way to bypass the password screen?

I am trying to switch laptops with my mom, and successfully wiped mine and restored it, but now the password that she used on her computer isn't working on this computer. Is there any logical reason why the two passwords would be different, if I restored her information from a Time Machine backup? Aditionally, Is there a way to bypass the password page on startup to make a password that my mom knows?

If Disk Warrior does not work you can try the following steps (but they may not work if the disk has a hardware error).
Get the disk (DVD or CD) that came with the system (since you have it listed as 10.6.8). If it is 10.7 or 10.8 use the Recovery partition to boot from or the USB installer if you have that option.
Insert the disk then power down
HOLDING the C key, power up to boot from the disc.
Get to Disk Utility
If Disk Utility will now show your hard drive, use DU to REPAIR the disk.
When it completes the Repair process successfully as indicated in DU, do a shut down. If Repair is not successful then an different course of action is indicated below.
Then HOLDING THE APPLE (or Command key depending on your keyboard) KEY AND THE OPTION KEY AND THE LETTER P AND R KEYS, continue hiolding them until you hear the chime tone for the THIRD time then release all four keys.
If REPAIR is not successful, use the Install disc as a boot and REINSTALL THE OS X OPERATING SYSTEM DO NOT ERASE THE DISK OR VOLUME FIRST. REPEAT DO NOT erase the disk or volume before trying to reinstall the OS X operating system. After re-installing the OS do a software update. Note that ERASING the disk is NOT required to do an OS re-install. This allows your existing data and application files to remain.
If that fails then you are down to the "bitter end" of erasing the volume and reinstalling the OS and then all the other software.
If erasing the Volume fails then your last hope is to completely erase the entire hard drive, repartion the disk and try a re-install.
If that fasils then you may have a defective hard disk.

I have a macbook and when I power it on and then select myself as a user...It won't power up. It stays in the white screen with the apple logo. I am online currently under 'guest user'. Is there anything I can do from the keyboard to fix this??? Help!!!

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!

It worked for a day but now when I try to charge it, it keeps switching back and forth from the large full screen icon of a low battery and a lighting bolt below to the blue screen with the apple symbol in the middle. I had it on charge all night but still dead.

We need to get you moved. This forum is for mini-tower Macs built between 1998 and 2005 and doesn;t get as much traffic ("eyeballs on the problem") as the forums for newer Macs.
Please do "About this Mac" from you Apple menu and tell us what that says for "processor" and Mac OS version. Looks like this:
or this for later Mac OS versions:
With that we can figure out which of the two iMac forums you need and get the Hosts to move your post.

Updated iphone 5 to iOS 6.1.3, now trouble with keyboard not responding correctly and screen zooming in by itself...

updated iphone 5 to iOS 6.1.3, now I am having trouble with keyboard not responding correctly and screen zooming in by itself...
Buttons pressing themself...
Also, my main screen is permanently zoomed in...
suggestions?

Double tap the screen with THREE fingers, that should get it back to normal again.
Then go into Settings > General > Accessibility > Zoom > OFF.
Not too sure about the keyboard and random button presses though. Back it up and restore from iTunes, see if that fixes it.

My mac book pro on start up shows a white screen with a folder with a question mark in it then switches to the apple symbol with the loading bar under it but it freezes about half way. Only started to have problems since upgrading to yosemite any ideas.

I do hope you have recent backup, because it look like your hard disk is failing. You can start up in Recovery Mode, and run Disk Utility to see if the disk can be fixed: OS X: About OS X Recovery - Apple Support

My MBP 15 inch can't switch off (freeze at blue screen with spinning wheel)

Whenever i try to "shut down" my MBP, it will freeze at the blue screen with the spinning wheel (that keeps spinning like 'eternally')! Any idea how to solve the problem?
I tried booting from the installation disk and repairing disk with "disk utility" but to no avail. Have also tried repairing disk permissions... Any idea how else should i tackle this problem?
Currently i can only switch off my MBP by holding the power button (forcing it to shut down)...
Please help Thanks!

Launch the Console application by entering the first few letters of its name into a Spotlight search, and select "system.log" from the file list. Enter "BOOT_TIME" (without the quotes) in the search box. Note the times of the log messages referring to boot times. Now clear the search box and scroll back in the log to the time of the most recent boot when you had the problem. Look for error messages in the minutes before that time, and post them here -- the text, please, not a screenshot. Edit out excessive repeats, if any. Do the same with kernel.log.
If the logs don't go back far enough in time, scroll down in the Console file list to /private/var/log/system.log.0.bz2 and /private/var/log/kernel.log.0.bz2. Search those archived logs, and if necessary the older ones below them, for the same information.
Also in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. For privacy’s sake, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please do not post shutdownStall or hang logs -- they're very long and not helpful.

Odd... went to get cuppa coffee, came back my monitor was BRIGHT orange, full screen,, with slight vertical rib pattern, kind of like corrugated cardboard... very slight pattern... what gives.... oh, everything was frozen, no cursor no keyboard, zip. Used back off button. Turned it back on, everything normal...
Had lots of sudden closures like this lately... but usually gray, black, deep blue screen... a couple with the same vertical corrugation pattern only in two shades of pale gold, or grays... what good times we have with apple... never know what'going to be looking back at you next. But BRIGHT ORANGE? Help???

Sounds like the graphics card. Run the Hardware Test in extended. Not a great diagnostic, but should pick up something really blatant like this.
