I HAVE A POWER MAC G5 AND IT WONT POWER UP.

I have a Power Mac G5 (late 2005). It will not power up.I Have already replaced the PRAM battery and tried hitting the SMU button. Nothing.

Pull the plug from the wall receptacle (the wall receptacle works, right?).
Press the power button (This is to drain builtup charge).
Replug the power cord to the wall receptacle.
Do you hear any clicks?
Press the power button. Still dead?
If you hear two clicks after reconnecting power, the PSU is likely dead.
Using a volt ohm meter (multimeter) you can test the PSU:

I have a power mac G5 and want to play sims 3 on it.

I have a power mac G5 and want to play sims 3 on it. When I click on the disk from the desktop it says "you can not open the application the sims 3 installer, because its not supported on this architecture." How can I fix and or resolve this issue? Thanks in advance! Connor

Sorry, but The Sims 3 require an Intel CPU Mac running OS X Leopard 10.5.7 or greater.
Your G5 is IBM PowerPC Mac and therefore will not run on that hardware architecture.
No workarounds. You need a newer Intel Mac to play this version of The Sims.
Sorry,

I have a new MAC MINI and I want to install a second monitor. I have one connected to the HDMI and it works. I can't get a signal to the other one. It is connected from the thunderbolt to its HDMI port. How can I make it work?

Could be a bad cable or bad Thunderbolt port.
You have 90 days of free telephone support on a new device. You can call them at 1-800-MY-APPLE. Have your Mini's serial number handy
You can also make an appointment at the Genius Bar of an Apple store.

I suspect the monitor has an ADC connector

If so you need one of these:

Otherwise what connector is on the monitor?

I have a Apple Mac desktop and recently was unable to access any YouTube, movies, videos, etc because a "Blocked Plug-in" message comes up with no error message. It asks to upload Abode Reader, but upon completion of this the message is the same.

I have a Apple Mac desktop and recently can no longer access Youtube, videos, movies, etc because I get a message reading "Blocked Plug-in". There's no error message but it does say to upload Abode Flash Player and the problem will be solved. I do this but it doesn't fix the problem. What am I doing wrong?

if you already downloaded the adobe flash player onto your mac and still getting that message that means you need to finish the installation of the flash player
you do this by opening a finder window and going to your downloads, find the flash player in here and then double click on it and follow the prompts to complete the installation.
after this is completed you will need to completely quit out of the web browser you're using then reopen it for the change to take affect and your issue should be resolved. if it's not you need to contact adobe their number is 800 642-3623.

I have a new mac pro and can't get a side scroll bar. What can I do to get this?

I have a new mac pro and can't get a side scroll bar. How can I get this?

The scroll bar is now set to appear automatically when you start scrolling with a trackpad or scroll wheel mouse. If you are using an mouse without a scrolling device, you should change a setting.
In System Preferences, click General, and in the Show Scroll Bars section, click the option for how you want it to work. If you want to see them all the time click "Always."

HT1209 I have a music collection on my iPod (160GB Classic). I have that collection on my old Mac Book. Now I have a new Mac Pro and want to transfer the collection to the new Mac Pro, is that doable?

I have a music collection on my iPod (160GB Classic). I have that collection on my old Mac Book. Now I have a new Mac Pro and want to transfer the collection to the new Mac Pro, is that doable?

Thanks roaminggnome. Can I do that transfer wirelessly or do I have to get a large jump drive to copy and transfer. I presume that I cannot use my iPod right?

I have a 2009 Mac mini and the wireless card has never worked, would I be able to cover it with my three year extended warranty?

If you mean AppleCare, then I would believe the answer will be yes.
First make sure you have a full backup of everything on your Mac, then run, don't walk to your nearest Apple store.
Note: Due to your Mac now being in computer years, somewhat elderly, Apple may not have the require parts in stock. This will either mean you might have to leave it with them for a number of days, or maybe they will offer you a new Mac mini. While a new Mac mini (if offered) might be a welcome possibility be aware that the new Mac mini no longer has a CD/DVD drive and it comes with Mac OS X Lion and as a result might not run some of your old software.

Have you tried checking the Store drop-down menu in the iTunes interface to see if you are signed in the existing account?
