HT1237 How can I install the firmware without an installed operating system?

I'm trying to update the firmware on a mid2010 macbook pro whose hard drive failed. In order to use Internet Recovery I need to update the firmware. I don't have an OS to boot to YET so I'm no sure how to use the DMG file via a direct boot.

I started down this path because as per http://www.apple.com/macosx/recovery/ it says "if your Mac problem is a little less common — your hard drive has failed or you’ve installed a hard drive without OS X, for example — Internet Recovery takes over automatically". After doing some research I see that in order to get Internet Recovery to work you need an upgraded firmware, hence my opening question. Also at that link it says "Not all Macs running OS X Lion are enabled for Internet Recovery. But Apple still has you covered with the Recovery Disk Assistant." so I tried going down the Recovery Disk path. To be honest, w/o the original restore media, I wasn't expecting any of this to work, but the language on the macos/recovery site makes it seem like it is possible.
It is very possible but you need to create the Lion Recovery Disk Assistant, Recovery HD USB drive, on the computer it is going to be used on from the Recovery HD partition that is on that computer when Lion and the R-HD is on that system.
In all honesty Apple should have a method and instruction on how to create a REAL Lion Install Thumb drive or DVD if you like. In stead of this STUPID Download system.

I have an iPad that I want to update to IOS 5.1. I have several apps that each were installed using a different iTunes ID. How can I update the IOS without losing the apps?

To update your phone requires using the latest version of iTunes, on your computer, as well as Internet access. The update to iOS 5.0 or higher is an erase/restore deal, so you not only have to make sure all of the content, currently on your phone, is on your computer and accessible, you need to update iTunes first, have Internet access, then update your phone. There is no way around this fact. You could go to an Apple store or use another computer, but you run the risk of losing all of your data it you do that.

What is the GarageBand version that your friend is using?
If it is GarageBand '11, version 6.0.5, you can buy GarageBand '11 as a boxed retail version with the iLIfe '11 bundle, e.g. from Amazon.
Then you can upgrade GarageBand '11 to 6.0.5, using this upgrader from the Support page:
GarageBand 6.0.5
GarageBand 6.0.5 will work well with your system. But if your friend is using the newest GarageBand 10, this will not help. Then ask your friend to send you audio files for each track, so you can recreate the project from the audio. Or your friend could also use GarageBand '11 for the projects you want to share, that will run well in all newer MacOS X versions, even with GarageBand 10.0 installed on the same system.

Get an iTunes gift card & redeem that in iTunes using your existing Apple ID.
Then the option for none, regarding a credit card should appear.

I have a keynote presentation that includes a significant amount of video. When I edit the keynote slides (not the video slides) how can I save the changes without re-saving the videos (because that takes a VERY long time)?

I have a keynote presentation that includes a significant amount of video. When I edit the keynote slides (not the video slides) how can I save the changes without re-saving the videos (because that takes a VERY long time)? I edit the presentation depending on the audience to which I am presenting.

If you add a new slide with just a text box (therefore a very small amount of data), to an existing presentation then save, Keynote will only save the new content to the file, it wont save pre-existing content as its already included in the file.
The time taken to "save" will be very much shorter than a "save as" when all of the existing content is saved again.

How can I update the firmware all at once

I'm a tech support in a school, approximately our school has over 500 laptops, how can I update the firmware on all laptops at once?

Apple Configurator is the software you want - and it's free from Apple. However, I'm dubious that firmware can be updated all at once.

How can I use the gps without internet in my Ipad3 - 4G

How can I use the gps without internet in my Ipad3 - 4G. Do I need to download any additional app than the one that already came with it?

The Maps app included in iOS, at least as of the current version, requires an Internet connection, so you'll need to get an app that allows you to download maps to be kept on the iPad. MotionX GPS Drive is one such app, but there are others available.

How can i erase the firmware of cisco 7912 phone ?

how can i erase the firmware of cisco 7912 phone ? the firmware is crashed in this 7912 phone , i want it to download another copy from CUCM8.5 .
the way i did on 7911phone doesn't work on 7912.

You can try that procedure but I'm not sure how far that factory reset goes on those phones. I know the 7940/60 series you can blow out everything except the CNU which would do exactly what you are looking for.

How can I share the internet without any network distribution?

You'd have to select in Sharing Preferences > Internet Sharing > Share your connection from ETHERNET, and to computers using AIRPORT.

How can I remove the photos without deleting them from the album?

I am making a book in Aperture 3. I want to change some of the pages that I have put together, and want to remove some of the photos from some of the pages, to put them on another page. How can I remove the photos without deleting them from the album?

As a follow-up, I have found that clicking on the photo in the book also highlights the photo on the strip below. So, if you then hit delete, you will delete the photo from both the book page and the album (which is the book, the way I have it set up). If you only want to delete it from the book page, you then have to un-click the photo on the strip below, or both will be deleted. This seems unwieldy. I deleted 6 photos from a page and found all of them gone from the album. The only way that I can see to keep them in the album is to then unselect them from the bottom strip after selecting them fro the page. This seems to call for an extra step.

Hi. How can I delete the table without deleting the content? My pages is 5.2.2.

Hi. How can I delete the table without deleting the content? My pages version is 5.2.2. Thank you for your help.

There is no convert Table to text capability in Pages v5.2.2, as there was in Pages ’09 v4.3.
You can keep the table while making the table grid vanish, leaving the existing tabular text structure. Select the table, and under the Format panel > Table tab, the following settings will produce this output. If selected, you can refine its document placement in the Arrange tab.

I have tried resetting an iPhone 3 and I am unable to activate and sync it. How can I reset the device without using a computer?

Hello anacc,
Thanks for using Apple Support Communities.
For more information on this, take a look at:
iOS: Unable to update or restore
http://support.apple.com/kb/HT1808
Connect your USB cable to your computer but not to the iPhone, iPad, or iPod touch until step 3.
Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.If you cannot turn off the device using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the device turns off, release the Sleep/Wake and Home buttons.
While pressing and holding the Home button down, connect the USB cable to the iPhone, iPad, or iPod touch. The device should turn on.
Continue holding the Home button until you see the Connect to iTunes screen. When this screen appears, you can release the Home button:
Note: If the image of a battery appears, let the device charge for at least ten minutes to ensure that the battery has some charge, and then start with step 2 again. If you don't see the Connect to iTunes screen, try these steps 1 through 4 again.
iTunes should automatically open and display the following message:
"iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes."Note: If iTunes not open after two minutes, please open iTunes yourself.
Use iTunes to restore the device.
Best of luck,
Mario
