Question about Apple MacBook Pro Laptop Computer with Intel Duo Core 15.4 Inch PC Notebook

1 Answer

My screen shows 4 desktops at the same time. If I reset the PRAM it goes to 1 desktop, until it boots to the desktop and then it goes back to 4. See a shot here: http://andy.queencreekgoldbergs.com/tiled-display.jpg

That looks like Spaces is at work here.
It allows you to have more than one terminal so you can organize and distribute your desktop. I use at least 8 Spaces terminal windows myself.

To disable spaces here is what you need to do:
*Click on Apple menu icon located in upper left corner of your screen and select System Preferences.

* From within System Preferences, Chose Expose and Spaces. Your view will automatically default to the Spaces side.
* On the left side of this window, you will see a check box entitled "Enable Spaces" - just uncheck that box
and that should prevent Spaces from appearing when you boot up again.

* Also, click the Show All button and go to Accounts.
• Click the "Login items" tab to make sure Spaces is not one of the login items as well.

You should have no further issues with Spaces disabled.

**To learn all about how to work with Spaces, here is a great link from Apple:

1.Try a Safe Boot
Mac OS X 10.2 and later Safe Boot includes disk checking and repair. First start your Mac in Safe Mode. To do this, shut down your Mac. Now Turn on your computer by pressing the power key while holding down the Shift key. When you see the Apple logo, release the Shift key. After your Mac fully starts, restart your computer normally without holding any keys/buttons during startup. Note that Safe Boot is slower to boot.
2.Run Disk Utility
Turn your Mac off by holding down the power button for a few seconds. Turn on your Mac and hold down the Command and R keys until you see the Apple logo. Then you should see a "Mac OS X Utilities" window. Select Disk Utility, click your OS X hard drive and select verify/repair disk.
3.Reset PRAM
This may fix your boot failure. PRAM ("parameter random-access memory") stores some of your settings. You may reset PRAM. To do that, turn off your Mac. Now turn on your Mac. Then, immediately, hold down the Option-Command-P-R keys until your Mac restarts. When your Mac is starting up, release the keys.
4.Reinstall Mac OS X
If nothing above works, you may try this. Your Mac needs to be connected to the Internet. See number#2 above. Follow the same steps. Restart your Mac and hold down the Command key and the R key until the Apple icon appears; when you see the Mac OS X utilities window, select the Reinstall option.

Did you try resetting the PRAM and SMC?
Resetting PRAM and NVRAM

1. Shut down the computer (by holding the power button).

2. Turn on the computer. Wait until I hear the boot sound.

When the above 5 steps didn't prove to of much help you can try resetting the SMC.
Close the Mac.
Detach any peripherals, cables, power wires, battery etc.
Be patient for several minutes.
Re-attach all the cables, peripherals like before.
Now turn ON the OS X

Three-finger swipe between desktops not working as expected.


I'd try adjusting your setting in
Apple menu
System Preferences
Trackpad.

Not sure what key combination can affect those settings.
If that does not help try resetting the PRAM and or the SMC.

Resetting the PRAM may do the trick:
You reset the PRAM by rebooting a Mac and then immediately hold down the Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won't work.

you've tried rebooting, you've reset the PRAM, you've done it all, but your Mac is still behaving strangely. What next? In certain circumstances, resetting your Mac's System Management Controller (SMC) can be a solution. This is sometimes necessary to restore normal lower level system functionality to your Mac.

Here's how to reset the SMC on any type of Mac (and any version of OS X) and the type of problems that it may resolve.
When & Why Reset SMC on a Mac? Some Common Hardware Reasons

Typically it's power and hardware related issues that can be helped or resolved by resetting a Mac SMC, particularly if you're having these types of problems:

* Issues with your Mac's cooling fans and fan management: fans run constantly at high speed, fans run high despite low CPU usage and adequate ventilation, fans not working at all, etc

* Power management and battery problems: Mac isn't turning on, sleep isn't working, random shutdowns and reboots, battery isn't charging, Mac won't wake from sleep etc

* Light problems and improper lighting management: battery indicator lights aren't working, display backlighting isn't adjusting to ambient light changes, keyboard backlights not working, etc

* Video and external displays not working: display brightness functionality not working properly, target video mode isn't working properly, external display isn't working, etc

* General performance and functionality problems: abnormally sluggish behavior despite no CPU or disk usage, external ports not working, airport & bluetooth aren't showing up, external devices are not being found, etc

So now that you've concluded you need to reset your SMC (Note that the SMC is on Intel Mac's only), here's how to do it on MacBook's, MacBook Pro's, iMac's, Mac Mini's, and Mac Pro's. Notice that the reset instructions are different for MacBook and MacBook Pro's if you have an internal or detachable battery.
Reset SMC of a MacBook Air, MacBook Pro Retina, or MacBook Pro's with an internal non-removable battery

This is how to reset SMC on most modern Mac laptops:

Shutdown your MacBook Air / MacBook Pro
Connect the power adapter to your Mac
On the MacBook/Pro's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Boot your Mac as usual

Here's the key sequence to hold down:

Reset the SMC of a MacBook Air or Retina MacBook Pro

Do keep in mind that by resetting the SMC you will lose power specific settings, like the time it takes to sleep a Mac and other customizations to power settings. No big deal, but if you have made many changes to your hardware behavior you will want to adjust stuff like sleep behavior again.
Reset SMC of an iMac, Mac Pro, Mac Mini

Resetting SMC is different for non-portable Macs:

Shut down your Mac
Disconnect the power cord
Press and hold the Mac's power button for 5 seconds
Release the button
Reattach the power cables and boot the Mac as usual

Reset the SMC of a MacBook or MacBook Pro's with detachable batteries

mac reset the smc Older MacBook laptops with a removable battery can reset SMC with the following approach:

Shutdown the MacBook/Pro and remove the battery
Disconnect the power adapter, hold the Power Key for 10 seconds
Release the power key and reconnect your battery and power adapter
Turn your Mac on
Let boot as usual

Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.

Happy New Year,
Kerry

My monitor on a macintosh Gf is black since setting the resolution toohigh. What can I type in or do to get the resolution to decrease even though I cannot ee the scren as it is black? Thanks, Rochelle...


You could try resetting the PRAM which resets various things to default status. You do this by holding down the following 4 keys together "cmd" "option" "P" "R" at the startup sound, keep them held down until it restarts and keep holding them down until you hear the startup sound 2 more times and then let go.

If that does not work try booting up in safe mode by holding down the shift key at startup and then when it boots up change the resolution to one that works and then restart.

Hope this helps.

Power-on LED illuminates when power button is pressed, fans spin, and boot tone chimes, but there is no video


1. Reseat video card. (Make sure video card is fully inserted in connector and end of card is secured by the connector latch.)

2. Reset PRAM (restart computer while holding down Command-Option-P-R keys until second boot tone chimes)

3. Replace video card

4. Reset logic board. Refer to "Resetting the PMU on the Logic Board" in this chapter.

5. Replace logic board

Resetting the PMU on the Logic Board

The PMU (Power Management Unit) is a microcontroller chip that controls all power functions for this computer. The PMU is a computer within a computer. Its function is to:

tell the computer to turn on, turn off, sleep, wake, idle, etc.

manage system resets from various commands.

maintain parameter RAM (PRAM).

manage the real-time clock.


Important: Be very careful when handling the logic board. The PMU is very sensitive and touching the circuitry on the logic board can cause the PMU to crash. If the PMU crashes and is not reset, the battery life goes from about five years to about two days.


1. Disconnect the power cord and check the battery in the battery holder. The battery should read 3.3 to 3.7 volts. If the battery is bad, replace it, wait ten seconds, and then proceed to step 2. If the battery is good, go directly to step 2.


2. Press the PMU reset button once and then proceed to step 3. Do not press the PMU reset button a second time because it could crash the PMU chip.


3. Wait ten seconds before connecting the power cord and powering on the computer. If the computer does not power on, there is something else wrong with it; refer to the "Startup Failures" section of "Symptom Charts" in this chapter.

Note: The above procedure resets the computer's PRAM. After resetting the PMU, be sure to reset the time, date, and other system parameter settings.

Whats wrong with my apple computer has a blank white screen with a ? and it also had a blue screen the other day not working please help


A question mark on the boot screen is an indication that the machine can't find your boot drive. Usually this is trivially fixed by resetting the PRAM (holding down command-option-P-R after turning on the machine with the power button, until you hear the chime three times).
However, taken in conjunction with your other symptom, I would suspect a failing drive or a failing SATA channel (less probable). Does it boot from the original DVD without these symptoms? After booting from the DVD, are there any indications from the tools that the hard drive may not be showing as present, or may show intermittently?
If you have a good backup (Time Machine or otherwise), I would erase and reformat the disk with "write zeroes to all records one time," then reload the backup, and see if that fixes the problem. If not, you will need to replace the drive, and reload the backup (hope you have one) onto the new drive.

My iMac G4 turns on and goes to the grey startup screen with the apple and loading circle, but stays there, and gets stuck, and after a few minutes shuts off on it's own.


You may have to reinstall you OS e.g. tiger, leopard with the disks that came with your computer. that should solve your problem
