HT1490 Is it safe to calibrate the battery, i mean it won't mess it up or anything right because mine is brand new and I don't want to mess it up?

my mac says it is 2hrs till it dies then it changes to 4hrs and im scared cuz its literally brand new and it is doing this to me help me plz?

re-read the article and see if your mac has a battery that needs to be calibrated. If it says it has a pre-calibrated battery, don't calibrate it, it is not necessary.

I recently thought I was updating my Safari browser. When completed, I put all those little files that were on the desktop into the trash. Now my trash is saying it can't be emptied because there are locked files and I don't know how to unlock them

I recently thought I was updating my Safari browser. When completed, I put all those little files that were on the desktop into the trash. Now my trash is saying it can't be emptied because there are locked files and I don't know how to unlock them or get them out of my trash and they keep multiplying. And to make matters worse, I tried renaming them as pdf files thinking that might do the trick.

oh boy ! I'd ask you if you knew what kind of files they were or where they came from, but I don't think you could help me a bunch. Try going to the Utilities folder and running Disk Utilities. If you want to empty the Trash and it won't empty, go to the finder and choose "secure Empty trash". Worse case scenario-you may have to reinstall Snow Leopard, but I don't know what else to suggest. If you have a DVD of Snow Leopard, boot up from that, and reinstall the OS. This will not touch the stuff you have on your Hard Drive, then you can update from 10.6 to 10.6.8, otherwise Onyx? Maybe those files are part of the OS which needs them to keep running. if you hold down the Shift key on reboot, you can reboot in Safe mode and maybe you can take the files out of the trash that way
good luck

Should I calibrate the battery in my MacBook Air?

Should I calibrate the battery in my MacBook Air? The battery indicator reads (95%) although the battery is fully charged.

You don't have to but it's highly recommended for optimizing the performance, please read Apple's Battery Calibration article.

I wanted to calibrate the battery my new macbook pro turns off

You should perform this procedure when you first use your computer? is this true? new macbook pro on may 11 2010 what happed was today on may 22 2010 i wanted to calibrate the battery my new macbook pro turns off when it runs out of battery. 3 times Typically, when macs run out of battery, they go into sleep mode. However mine skips this completely and just turns off. WHY? does this mean the battery is bad?
Resetting the PRAM (http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html) fixed the problem in my case. then i did the calibrate the battery again this time it went to sleep not shut down i did this 3 more times why?
the 3 forced shut downs without entering SafeSleep. with logs indicating improper shutdown, will that cause severe corruption to the os and do i have to reinstall the os now?2.66 ghz 2010

the 9 more 4 in 10.6.4 forced shut downs without entering SafeSleep. with logs indicating improper shutdown, will that cause severe corruption to the os and do i have to reinstall the os now?2.66 ghz 2010 but if it happens again you should try
i hate to do this reinstalling the OS, if this do not work also, then you should call apple, or take your MBP to an apple store. on june 24 2010 i am going to talk to spence about this. so what do i do now? this happed on june 16 2010 4 more times
without entering SafeSleep. only one time it worked on 10.6.4

When I plug the battery cord in to my mac pro, it says it is charging, but no light comes on and the charge is still low. What's going on?

Good grief! I had not plugged the USB jack all the way into the headphone port on the iPod. Having taken that action, the iPod shuffle works great. My bad, as they say.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html

Make an appointment at the Genius Bar of an Apple store. If your iPod is defective and has not been abused Apple will exchange it at no cost.

Did all the updates that Apple requested in my 64 GB IPOD and the battery continues discharging very quickly. When this problem will be solved, because before these updates were downloading not the battery so quickly. Did we revive the Steve Jobs to resolve the problem, because each update only worsens the operation. I look forward to a quick, effective and definitive solution. Thank You. Ester

Can any one tell me how can I move to a different folder pictures, that I've cloned, without them staying aggregated? They all come together to the other folder and I don't want that- thanks

There's more to it than that.
Folders in Aperture do not hold Images. They hold Projects and Albums. You cannot put an Image in a Folder without putting it in a Project or an Album inside that Folder.
The relationship between Projects and Images is special: every Image must in a Project, and can be in only one Project.
Images can be in as many Albums you want. Putting an Image in an Album does not move it from the Project that holds it.
You can make as many Versions from a Master as you want.
What you want to do may appear simple to you, but it still much adhere to how Aperture works. I still can't tell exactly what you are trying to do (specifically: Images don't live in Folders; moving an Image from a Folder is non-sensical).
It can be very confusing (and frustrating) to get going with Aperture -- but it does work, and can be enormously helpful. If you haven't, take a look at the video tutorials on Apple's Aperture support site.
I feel as though I haven't helped you much -- but we need to be using the same names for interface items in order to get anything done -- and my sense is that you still haven't learned the names of the parts.

Unable to delete email from trash bin. How do I do this? If I select and chose delete, it doesn't. What am I doing wrong? My grand daughte is using my iPad and I don't want her to see some of the mail there.

Unable to delete email from trash bin. How do I do this? If I select and chose delete, it doesn't. What am I doing wrong? My grand daughte is using my iPad and I don't want her to see some of the mail there.

There are two ways that should work. When you are in the trash folder, you can swipe on the email in the list - left to right - and a red Delete button should pop up. Or you can select - Edit - at the top of the list of messages and then select the message and tap delete.
Not sure exactly how this works - but if you have restrictions enabled - especially since you let your grandchild use the device - that may be restricting what you can do in the mail app. Go to Settings>General>Restrictions. If you have it set to on - turn it off or see if you have mail restricted.

How can I get a pdf. to open in Safari, all i'm getting is a new window with a black, blank page, instead of the pdf., and I don't want to save the file to the desktop, Safari didn't use to do that, and I don't have Adobe in the internet plug in folder.

Hi
Please take a look to this thread Re: Can I refresh the browser rather than open a new tab?

I recently updated my itunes to the latest version. Now when I try to view music on my ipod, it says I have to sync it? My ipod was already synced to this computer before and I don't want to lose anything on my ipod or in my itunes. What do I do?

My ipod has always been synched to this computer...and I don't want to lose anything.

It doesn't say anything. It runs through the sync process like normal and tells me all of the songs that it's synking. But then when it says I can disconnect it, nothing actually synked.
