Try an archive and install of the OS. This will save your settings and files but reinstall the OS. You can do this by booting to the cd and choosing archive and install instead of erase and install. If it happens again, it could be a slowly failing hard drive developing bad sectors, or the less likely of bad ram.

Where is the power button on the mac computer

The power button is on the back of the LCD screen in the lower left hand corner. You should power down by clicking on the Apple Logo in the upper left hand front corner and choose "Shut Down". If your screen freezes, you can power off by pushing the power button and holding it.

Display is too large for screen

Hello Dr. Bankert and thank you for contacting Fixya, I will be glad to assist you.

What you need to do is turn off a setting within the System Preferences > Universal Access feature within your Power Mac G5.

To do this, you need to click on the Apple menu icon, located in the upper left corner of your screen. When you do click on that menu icon select System Preferences from the drop down menu:


Then go into System Preferences and look for the pane (icon) entitled Universal Access 9_16_2012_10_06_45_pm.png

• Click on the Universal Access and you will see this view:


Under the Seeing tab, make sure Zoom is turned to Off

This should bring your enlarged screen back to its normal size.

You can now also click the Show All button located at the top of that window (on the left side) to return back to System Preferences main window.

From within System Preferences, select Displays and try selecting a lower resolution like 1280 x 1024 or 1024 x768 for example and see if selecting one of those resolution settings helps to reduce the size of your display window.

Please let me know if any of these simple recommended steps help.
If you have more questions, I will be glad to assist you further.

I have an all in one Mac OS X with 2.4 GHz Intel Core 2 Duo processor. When I turn it on the screen is white with the spinning circle in the middle like its powering up but never does. It just stays...

You can check your hard drive's health at startup pressing command-s. you will see a black screen with white text. simply type "fsck -f" and press return. It should check your drive and tell you if something goes wrong with it, and repair it if possible. Then type "reboot" and press enter to test.
It this does not help, you can press the shift key at startup. It does the same thing, but also disables the extensions at startup, this will help you to find out what the problem is. The startup will be longer and it should ask for your admin password.
If this still doesn't help, you might have a hardware problem (hard drive). You can try to backup your data, erase the disk and reinstall the system. To backup you need another Mac, and a firewire cable. Press the "T" button at startup, this should set the Mac in "target" mode, allowing you to use it as an external hard drive. Then connect the firewire cable between the two macs. On the mac that is OK, you should see the hard drive icon of the other mac...
Hope that you will succeed and that it helped you someway

My G5 tower is no longer recognising my external iSight camera. The only thing that happened was that I switched the G5 off and on again, it was working fine previously. Can you help? Many thanks

Best thing you can do is to determine whether its the port or the camera.
If you go to the Apple in the upper-left corner, and go to "About this Mac", then click "More information", it will start System Profiler. On the left side, under "Hardware", click on "Firewire" and see if your iSight shows up. If you have another FireWire device, plug it in, and see if it shows up there as well. The solution could just be a dead iSight (hopefully!). The worst case scenario is a dead FireWire bus...
If you have a dead iSight, I'd guess that ebay would be your best resource at this point. If its a dead bus, I'm afraid it won't be terribly cost effective to fix it :-/

My daughter was installing a game on the mac and i don't know what she pressed, that now when we turn the computer on, a black screen with lots of words and symbols shows up, and we cannot move passed that...

It sounds like Verbose Startup. Try to reset the P RAM:

Hold down four keys, P + R + Command +Option and turn it on, it will reboot. Let go of the keys after you hear the second chime.
This should clear the white on black, but you may have a boot problem as well if your system isn't coming up all the way. This may require a software reload.

Resolution issue Acer V223w

Hi, I'm sorry to hear you are having trouble....
THis is a tricky one. My first step would be to connect another screen to your G5 and connect your V223w to another Mac... Are you able to do this, do you have access to another system, could even be a PC ( in the worst case )
Ideally, having 2 screens connected to your G5 would be the best situation.
THis way, with one working screen, you can attempt to modify the resolution and refresh rates on the V223w from the good screen, be sure to activate screen mirroring, otherwise you will not have access to the other window of monitors system preferences.
If you can get two monitors connected and mirroring is not an option, then either your monitor is KAPUT or the video card secondary port is KAPUT, try switching the port of the card your displays are connected to. I think they are both DVI ports. If the opposite screen is now working, then you know it's the port on the video card.
Hope this will get you through it.

Grid surrounding cursor and desktop icons

You have accidentally enabled "Universal Access"
Open System Preferences from either the dock or the pull down menu under the Apple in the upper left hand corner of your screen.

In System Preferences the 4th line down should have icons for "System" one of those icons (usually the right most) will be a blue circle with a person in it. This is "Universal Access"

Open Universal access and turn voice over and zoom off.

G5 imac.. with leopard can not get past sign in

If you've forgotten your password, you can reset it with the discs that came with your computer:

  1. Start up from a Mac OS X Install disc (one whose version is closest to the version of Mac OS X installed). Usually, you can start from the disc by putting it in your computer, restarting, and holding the C key. Or, put it in the computer and click the Install or Restore icon you see in the disc's main window (after which the computer will start from the disc without you needing to hold C). Or, you can use Startup Manager or the Startup Disk preference pane to select the Install disc.
  2. Choose a language, click the arrow button to continue,
  3. Mac OS X v10.6 or later: Choose Password Reset from the Utilities menu.
    Mac OS X v10.5 or v10.4: Choose Reset Password from the Utilities menu.
    Mac OS X v10.3: Choose Reset Password from the Installer menu.

    Tip: If you don't see this menu or menu choice, you're probably not started from the disc yet.

    : The default keyboard layout is U.S. English while started from the installation disc. If you use a keyboard layout other than U.S English, use the Input menu (the flag icon on the right side of the menu bar) to select the desired layout before typing a new password.
  4. Select your Mac OS X hard disk volume.
  5. Select the user name of your original administrator account.

    Important: Do not select "System Administrator (root)". This is actually the root user. You should not confuse it with a normal administrator account.

  6. Enter a new password.
  7. Click Save.
  8. Click the red button in the upper left corner to quit the application.
  9. Choose Quit Mac OS X Installer... from the Mac OS X Installer menu.
  10. Click Restart.

Changing mac preferences in single user mode

Start your computer by holding down the option key before pressing the start button. This should give you an option to choose which startup disc to use when starting the computer. Once it's restarted, go to the System Preferences and choose the specific startup disc that you want to use.
