HELP! I think I damaged my computer....

This is going to be posted in the G5 Power Mac section too....
Hi everyone. Is it possible to damage just the left (or right) channel on the stereo out? I still don't have an audio interface yet, so I've been using the stock headphone jack for my headphones, and the stock speaker out for my Creature Speakers. They are both quieter on the left side. I think this has been happening for a couple of months, I just thought I was losing my hearing a bit on the left side, especially with headphones on. Turns out I'm OK, it's the stereo outs that aren't working right.
I found out that it's not me when I plugged in my active monitors, KRK Rokit 8s, and tried both speakers in iTunes, Garageband and Logic Pro. I played with the panning in both GB and LP, but the speakers on the left weren't as physically active/vibrating as much as the right. I did switch the inputs on the KRKs to make sure it was the channel and not the speakers.
The left channel isn't gone mind you, it just sounds quieter, more muffled with less high end. Maybe even a little distorted. I didn't want to turn it up to high to see if I could hear distortion clearly just in case.
I'm really really hoping that this isn't a hardware issue (I know that there's a 95% chance it is). I'm really hoping that there is a small preference or utility app that can control the panning of the systems output and I just don't know about it. I'm still holding out hope for that.
But if there's no hope and it is a hardware issue, any suggestions on what I should do?
Thanks for your time and sorry for the long thread. I look forward to hearing from all you geniuses.

The exact same thing has not happened to me but these days before I go and play live with my MBP I always go to System Preferences and check the sound out balance (if I use the stereo out) because it's happened several times that the setting is not centered although I have not touched it myself (nor has anyone else). I think it might be for instance iChat that changes it (silences the left speaker because the microphone is there) and then doesn't change back when voice/video chat ends (esp. when the software crashes). I'm glad your hardware is not damaged after all!

Help I think I have Macvx on my computer and I can't get rid of it.

Help,
I think I have Macvx on my iMac late 2012 21.5 running the latest OS.
I am getting heaps of ads in my web browser.
I have seen similar question from other people and responses explaining to find and search for it in your applications menu but I can't find anything that relates to it or that was installed recently.
I have even looking in the library and through spotlight search searching the specific words Macvx and Vidx.
Please help,
Thank you very much.

Helpful Links Regarding Malware Problems
If you are having an immediate problem with ads popping up see The Safe Mac » Adware Removal Guide and The Safe Mac » AdMedic.
Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.

If you require anti-virus protection Thomas Reed recommends using ClamXAV. (Thank you to Thomas Reed for this recommendation.)
From user Joe Bailey comes this equally useful advice:
The facts are:
1. There is no anti-malware software that can detect 100% of the malware out there.
2. There is no anti-malware that can detect everything targeting the Mac.
3. The very best way to prevent the most attacks is for you as the user to be aware that
     the most successful malware attacks rely on very sophisticated social engineering
     techniques preying on human avarice, ****, and fear.
4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
    your computer is intended to entice you to install their malware thinking it is a
    protection against malware.
5. Some of the anti-malware products on the market are worse than the malware
    from which they purport to protect you.
6. Be cautious where you go on the internet.
7. Only download anything from sites you know are safe.
8. Avoid links you receive in email, always be suspicious even if you get something
    you think is from a friend, but you were not expecting.
9. If there is any question in your mind, then assume it is malware.

MacBook Pro 2011- Allowed updates to install for iTunes software and Microsoft office (I think). After rebooting, computer wouldn't progress past grey apple screen with loading circle.

I have a MacBook Pro 2011. I allowed updates to install for iTunes software and Microsoft office (I think). After rebooting, computer wouldn't progress past grey apple screen with loading circle. No progression bar ever appeared. It just sits and spins. I tried rebooting with Command + Option + R + P and hearing the chime twice....this did not work.
I also tried Command +Option+R which took me to internet recovery. From there, I chose reinstall Mac OS X Lion 10.7 but it says my hard drive is locked so I wasnt able to select it. What do I do???? Help! I don't want to lose my files and it doesnt appear that I've used Time Machine Back Up.

I you upgraded to OS X 10.8, then use RecoveryHD by holding Command R at boot time (no option) and reinstall OS X over itself that way so your installing Mountain Lion.
Also Disk Uility can be used to Repair the Macintosh HD parttion.
Also you can use that RecoveryHD to format and install OS X onto a external drive, then option/alt key boot from it and access your files on the non-booting internal drive before erasing, reformatting and reinstalling OS X fresh.
Create a data recovery/undelete external boot drive

Does the retina display help your eyes when on the computer?

Does the retina display help your eyes when on the computer for a long period of time? Does it make a difference if you have eye problems?

First, I'd suggest posting your question on the MacBook Pro forum. This is the Mac Pro forum, where the computers start at 50 pounds and go up from there (at least so far).
Second, I think it depends on what your eye problems are. I can say that there's a lot less reflection off the screen than the standard MacBook Pro glossy screen; it's similar to the anti-glare screens that you can find on other Mac laptops. The Retina display also has the ability to present a much crisper image with compatible software.

HT1386 my iphone does not sync with itunes on my second authorized computer, please help. i changed the first authorized computer in May 2012 and have been using the second authorized computer since then but it cannot sync - please help!!

"I was thinking I would just connect my iPhone and all of my music and other stuff would transfer to the new computer. "
Not true. The music and pic sync is one way - computer to iphone. The only exception is itunes purchases. Without syncing: File>Transfer Purchases
You really should transfer everything from the old computer, or your backup copy of your computer. Since you do not have access to the old computer, then use your backup copy of the old computer.
If for some reason you have failed to maintain a backup copy of your computer ( not good), then you would have to transfer itunes purchased as described earlier. Any other itunes content would be lost.
You can e-mail photo library pics to yourself, but they will not be of the original quality.
Before syncing, enter at least one unique contact and calendar entry on the computer. When you first sync, then you should get the option to merge the data.

HELP - Apple Store mishandling of my computer

I left my Powerbook 17 to an Apple Store last week, to have the hard drive changed. They have damaged the casing of the computer while it was in their care. The casing is bend in two places and start to split. I contacted the Apple Store. They don't want to acknowledge that! The repair that was supposed to be 325 USD + tax, is now over 900 USD. I have a copy of the repair form that doesn't refer to any damage. I feel completely let down by this Apple Store.
Any idea on who to contact to get this resolved ?

Thanks for your response. I did talk to them, He was denying that a problem could have happened at his store (North Fork in GA). Basically saying that if someone of his team damage a computer they always report it.... and that they will never fired anyway someone mishandling a computer....I don't think I could have find a positive outcome with him. I send an extensive email documenting my misfortune to him (i am still waiting for an answer). I am 100% sure someone did something to the computer at the store.
I finally found resolution, contacting the person that was suppose to repair my computer, that was send originally by the store, to the repair Center in Texas. That person listened and is taking care of the matter the right way. So I am getting a positive outcome, but after hours spend on the phone and sending emails...

It is hardly Apple's fault that Epson can't/won't update their driver, but at least Epson suggest that you use the Gutenprint driver, which in any case is far better that what Epson offer.
You can get it here:

You can download the latest version from here:

Have you downloaded the recent Apple update to Epson drivers?

Did you try here:
iOS: Device not recognized in iTunes for Windows
Does the computer have iTunes 10.7 or later?
Does the iPod charge?
Some 5G iPods were shipped with defective Lightning cables.
Try on another computer to help determine if you have an iPod, cable or computer problem.

How do I get my Mac, G5, 10.5.8, to print? Printer tech support thinks it is a computer problem. Any ideas?

How do I get my Mac, G5, 10.5.8, to print? Printer tech support thinks it is a computer problem. Any ideas?

Hi Dwayne,
If necessary (unless your operating system already contains the printer software needed), a downloadable driver for a Deskjet 5420v Photo Printer (is this the exact model?) and Mac OS 10.5 appears to exist according to the support web page below:
http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=1105187&lc=en&cc=us& dlc=en&lang=en&cc=us
To begin with, have you verified that the printer is able to print at all (that the print cartridges are OK, et cetera)? This can usually be done by trying to print a test page (from the computer) via an HP printer utility, or possibly by generating a self-test page (without a connected computer) using an appropriate button combination on the printer itself.

Please help my printer talk to my computer. An error message always occurs when I try to print and Firefox self-help has not fixed the problem. Please help me directly with fixing the issue. Thank you.

Can I use my normal power adapter in another country without damaging my computer?

I just bought a brand new MacBook Air in the UK a couple of months ago, but now I'm moving to Mexico. I want to know if I can keep using the power adapter that came with my laptop, just adding a plug compatible with Mexican outlets. Will it damage my computer at all??

No, there's no danger to either the power adapter, or your computer. You may need an AC prong adapter, and it's best to buy one after you arrive in your new location.

Need help re-synching iPods with new computer and getting iTunes to...

Need help re-synching iPods with new computer and getting iTunes to recognize our iPods (it doesn't even recognize them when they're plugged in).
Hubby wiped my harddrive for me, so now I need to get everything back in proper places. I'm using windows XP and installed iTunes once again (I believe it's version 8). I also installed all of my iTunes songs. Now I need to know where to go from here. We have 3 iPods and I need to get them all synched once again. I know how to create different libraries for each of us, but I can't figure out how to get our songs back into our iTunes libraries. When I open iTunes and plug in an iPod, iTunes doesn't even show that an iPod is plugged in.
What do I do now to get each of our iPods synched with our own libraries?
TIA
Brandy

Thanks Zevoneer. The "Restart ipod service" worked and itunes is now recognizing my ipod! Hooray!
Okay, now how do I synch all of our ipods with our individual libraries (I don't want all of my kids' songs and vice versa)? We each have hundreds of songs on our ipods that we don't want to lose.
Thanks again!

Can Bass damage your computer?

Hello, I have a macbook pro with a pair of Bose Companion 3 series 2 computer speakers. The bass module is on the floor about 3 feet away from the laptop. I was wondering if the bass vibrations could damage my computer especially the hard drive since while playing music, i can feel the mac slightly vibrating. Any precautions or sugestions that i should take? Thanks.

I would not worry about it.
However, I have noted a link to a very interesting read on the subject for you to check out.
