How can I delete all data from my macbook air?

I'm trying to delete all the personal information from my hard drive, but leave the iOS. HOW????

Oops -- the Mac's Operating System is Mountain Lion, not iOS. I will assume you mean delete all your information, but leave Mountain Lion.
To do that, you can reboot your computer holding down the "Command" and "R" keys at least till the Apple logo appears (6 or 7 seconds). Choose the recovery disk. You'll then be able to erase your hard drive using Disk Utility and then reload Mountain Lion.

How can i delete all data from treo 750 - where is the hard reset button for the treo 750

I'm giving my phone to my brother and want to delete all my data from the treo 750 (AT&T). All the other posts I read doesn't tell me where the reset button is. Please Help!

Hello and welcome to the Palm forums.
A hard reset wipes everything off your device. A hard reset is performed by holding down the power/end call button while removing the battery from your device for a few seconds. Keep your hand on the power/end call button until you put the battery back into your device. After you put the battery back in, the screen will say "Palm Powered." Take your hand off the power/end call button. You will now see a screen in 5 languages prompting you to erase all data from the palm. The screen will say "erase all data? Yes - up, no - down" and you need to click on the up arrow (button on the 5 way navigator on the bottom of the treo). This will erase all the info from your device.
I hope this was helpful!

HI, I need your help. How can I delete all data, when I do not have the special security code, which I didn´t remember ? I also think, that I never create this code before. But I cannot put my settings back.

You must remember the code, if you can't then take the phone and proof of purchase to an Apple Store.

Unless you have already set up the FIndMyiPod feature (could have been done via MobileMe before iCloud) and wifi is on ans some other conditions are met you can't wipe/erase your iPod.

How do I transfer all data from my Macbook to my iMac?

I want to transfer everything from my macbook to my imac anddelete everything presently on the imac. I also need to keep all data on the macbook. How do I do this please?
The main reason for this is that the Mail app on my iMac no longer gives a window or any option to rebuild so I cannot see my mail on it. I have to use iCloud. I have tried the re-install OSX with no improvement.

Welcome to Apple Support Communities
When you start up your iMac holding the T key, it will start up in Target Disk mode. In this mode, the iMac's hard disk appears as an external drive in your MacBook Pro, so you can access there and recover your data.
After starting in Target Disk mode, open a Finder window in the MacBook Pro and you will see the iMac's hard drive in the Finder sidebar, under "Devices". Select it, navigate through your folders and copy them to your MacBook Pro's hard drive.
You can also use Migration Assistant > http://support.apple.com/kb/HT4889?viewlocale=en_US&locale=en_US

How can i cancel the cooling from my MacBook Air?

How can i cancel the cooling system from my MacBook Air? It is running full speed by the start ervery time, also when the MacBook Air is cold.

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

How can I delete all songs from iCloud library?

Hi,
I have a strange issue and couldn't really find any information about this on Google, so I thought I would try here. I'm kind of surprised this hasn't come up for other users yet (or maybe it has and I'm just missing it.)
I matched my iTunes library yesterday. About 60% of the songs were matched, 15% were uploaded and 25% were errored. I really like iTunes Match but I decided that I want to micromanage the library to get the best match results. To do this, I wanted to do the following:
1. Remove all songs from my iCloud library
2. Create a new iTunes library for use with iTunes
3. Add to the library, artist by artist to match/correct.
I began to do this in my new library and it was working fine. However I then decided to completely clear the old library, so I went into my original library, deleted all songs and definitely selected the option to delete from iCloud. I am 100% positive I did this. However, none of the songs deleted. They are not available in my original library (I have checked the option to display songs not on this computer) and they don't show up in my other library, either. I have no option to download the songs from iTunes on any computer, though I retain access from my iPhone.
So, I need to delete these songs from iCloud. It does me no good to have them there when they're so disorganized and especially when I can't access them from most of my iTunes enabled devices. I was thinking of calling Apple to see if they could clear my iCloud library but a. I'm not sure they will and b. I don't want to pay $29 to discuss this with them, as I feel it is an issue with iTunes Match/iCloud and should be complimentary.
I thought that maybe the songs would delete over time, since I know the iCloud servers are heavily taxed at the moment. However, it has been about 15 hours and there is absolutely no change. The iMatch section of iTunes shows that there are songs available, but none of them are; and since my plan is to reupload to iCloud anyway, that's fine--I just need to find out how to actually make the delete go through.
Thanks!

I called Apple and spoke with a customer service representative regarding this issue. I was given the two things to try, and if they don't work, I was told I can call back in:
1. Go to iCloud.com and look at the advanced options. Since Photos can be deleted here, the representative thought there may be an option to remove songs here as well.
2. Go into the library that has the songs that were deleted and click Update iTunes match.
I tried #1--this didn't resolve the issue, as there is no option to remove songs this way. I can't try #2 right now since I'm at work, but if anybody else with this issue can try that step it can help us get the ball rolling on it. After I try that, I'll call Apple back to discuss this further.

How can I remove all data from the iPhoto app?

I wanted to reset my iPhoto library and remove all places, faces and events recognized from the pictures, so I copied my iPhoto library to a hard drive and then deleted it and emptied the trash. Copied the data to iPhoto again and took a look. The library was exactly the same. When I saw my activity monitor I realised there were just 12 gigabytes remaining in my hard drive (I'm using a 128GB Macbook Air) and before doing all this there were 47 gigabytes remaining. My iPhoto library is about 35GB, and I think I didn't replaced the library, I duplicated it. I'd really like to know if someone can help me finding the other library and deleting it, because I'm getting out of space in my mac.

Your post is not clear
I wanted to reset my iPhoto library and remove all places, faces and events recognized from the pictures, so I copied my iPhoto library to a hard drive and then deleted it and emptied the trash.
OK
Copied the data to iPhoto again and took a look.
Exactly what does this mean?
Probably your best bet is to run your iPhoto library on an external drive
Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

How can I delete Facebook events from my macbook calendar?

I'm using a MacBook Pro. I want to know how to delete Facebook events from my computers calendar, because it's taking up space and preventing me from seeing other events on that day.
BUT, every time I try to delete it, an error message pops up "Only the calendar administrator and any delegates with permission can make changes to read-only calendars. To make changes to the calendar, contact the calendar administrator."
And I can't delete the event. Have not tried declining the event because I don't wanna offend the person who invited me.
Not a computer whiz, so idk if this helps but:
MacBook Pro
OS X Version 10.9.4
Processor 2.5 GHz Intel Core i5
Memory 8 GB 1600 MHz DDR3

How can you delete downloaded games from a Macbook Pro to create more available space?

it says I have 0KB available... how do i get rid of downloaded games to create extra space on my computer?

Start by dragging the games' applications to the Trash and Empty the Trash. See, also:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead. Download Easy Find at VersionTracker or MacUpdate.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
AppZapper
Automaton
Hazel
CleanApp
Yank
SuperPop
Uninstaller
Spring Cleaning
Look for them at VersionTracker or MacUpdate.

How can I delete the "Other" on my MacBook Air HD?

I recently noticed that on my 128GB hardrive on my MacBook Air, there is only about 1.66GB left of space, and that 59.97GB is taken up by "Other". This is really frusturating seeing as I have no idea how to access these files and delete them. I think it might be local back ups from Time Machine, but I have backed up my hardrive to my external drive since i noticed the huge loss of space and I have since then turned off Time Machine but stiill the "Other" is still there. So could someone please help me in figuring out how to get rid of all this excess filler would be fantastic. Thanks in advance to anyone who can help me figure this out, its highly appreciated

Local snapshots from Time Machine are in the "backups category". "Other" is considered a miscelaneous category. It is made up of everything that doesn't fit in the other, more defined categories. You don't want to delete everything in there as is contains some important things, such as the operating system, system files, etc. You can download OmniDiscSweper to find large files.
