Is there an easy way to securely delete everything on my macbook PRO except for the OS and applications?  Giving my old Macbook to a family member.

Is there an eay way to securely erase all information on my macbook Pro except for the OS and applicatios?  I'm donating my computer but want to eliiminate my files and info.

Yes, boot to your install disk (start up while holding C key).  Go to Utilities>Disk Utility.  Choose erase and format your disk (make sure it's formatted as Mac OSX extended journaled).  There's is a button for security options.  Choose the 0 option (don't choose the multiple pass versions, or it will take forever, but that's extra security).  The 0 option writes a 0 in every location on the drive, and it takes a few hours.  It would take CIA or highly skilled hacker abilities to dig out any information.
Once you wipe the disc, reinstall OSX.  You're done.

  • IPod 6th gen deletes everything off itself out of blue, for the second time

    Hello,
    I have a June 2008-bought 6 gen 80 Gb iPod classic and, knock on wood, it's the first one I've had that didn't die on me within a year. However, I am experiencing an annoying problem with it. This happened for the second time: iTunes freezes at the point I'm adding songs to the iPod and the moment it unfreezes, there's nothing on my iPod and I have to start over. Does anyone have an idea what is wrong and how should I prevent this, as it's obviously annoying?

    So, I did all that and started filling the iPod. At some point when it was 1/4 full, iTunes froze and started "verifying" it. I plugged it out, but too late, it said there was no music on it.
    However, when I plug it in, it shows that the amount of space I used is actually taken...but not by music. This is getting odd.
    Is the problem any clearer now?

  • My iPhone's sound does not work except for the alarm and the volume bar is not there.

    Hi, thank you in advance if you can help.
    When my iphone 4 is not plugged in to headphones the sound does not work, and if I try to adjust the sound with the plus and minus buttons in the side it comes up like normal saying "Ringer" but then there is no bar underneath it. Sometimes the sound will work for a couple of minutes. However, there is definitely no problem with the speaker as the alarm always works perfectly fine.
    I have tried restoring it, this did not help.

    what you could even try is to write down a few contacts that you would need to get through a single day, restore it to factory, punch in those few odd contacts,
    No.  What he should be doing is syncing his contacts to an app on his computer or cloud service, then sync them back to the phone (without restoring the backup). 
    Never rely on the backup for contacts.  The contact info stored there may be incomplete and is only meant to maintain the recent calls and favorites lists.

  • I have ordered the rMBP and will giving my old MBP (2010) to my girlfriend what is the best way to remove the programs and files that she wont use and make it her computer rather than my old one?

    I have no real need to upgrade but as a student the price it would be silly not to.
    I will be giving my MBP to my girlfriend but she wont use a lot of the software on there such as the final cut and CS5 and would rather use the space for her own iTunes library. Some will be kept on though like the old office suite as i have bought the 2011 one as well
    Can I also remove myself as a user on the macbook so the only login is hers? I would rather it was her computer rather than my old one!
    Cheers in advance!

    Hey, man, I'd be excited, too!
    She'll have whichever operating system that came with your computer. Your updates are tied to your Apple ID so if you've purchased updated OS X versions, she'll want to reinstall them using her own Apple ID (yes, it will cost her something but not much).
    Kappy's a know-it-all (and I mean that in the politest of terms) who's a frequent poster here. He has a 'canned' script about how to get your computer ready for resale. I guess he just doesn't have enough points yet to make it an User Tip, but it's a great little rundown of what to do.
    BEFORE you erase everything, I would purchase (if you don't already have one) an external USB hard drive and use Time Machine to backup everything. When you startup your new computer (or afterwards if you just can't wait to see the clean, crisp text in TextEdit) you can use Time Machine to properly migrate all your files, apps and all, onto your new MBPR. If you're not familiar with Time Machine, see  http://pondini.org/TM/FAQ.html. Oh, yeah, since you have Office 2011, you'll need your activation code handy as, for some reason, the activation code does not carry over when you use the Time Machine restore. All Adobe, etc., apps are fine. It's just that damned MS Office that gets you.
    Hopefully Kappy will jump in here. If not just post a message "Kappy: Preparing MBP for resell?" or something to that effect and I'm sure that he'll see it.
    Good luck,
    Clinton

    My company will no longer support/pay for my iphone and I need to transfer my contacts out of my iphone and into a new phone, is there any easy way to do this or am I stuck with writing my contacts down and re0entering them into a new phone?

    You should be syncing your contact to your computer.

  • Airport Network: Is there an easier way to turn on my network?

    Airport Network: Is there an easier way to turn on my network? I just bought an ipod touch and like to turn on my airport periodically from my iMac to update stuff from home. My network does not appear on the drop down list. I have to go to system preferences each time and select "sharing" then Internet Sharing and start my internet sharing. Then the arrow icon appears in the menu bar and all is well. Is there an easier/faster way to do this?
    ps I tried the Airport discussions but no luck.

    What the **** is your issue?
    You show Leopard for ONE computer - I thought that possibly you were using the other one(s) after I posted and made no such assumptions on what OS it was running.
    It's quite possible the other computers listed are running Tiger or other.
    You have students?
    You'd better teach them to not only pay attention, but to provide complete details, wise guy.
    You're the kind of person that just ***** the fun out of trying to help.

  • HT201302 I have over 1000 photos in my camera roll, and I have saved them to my computer.  Is there an easy way to delete some or all of them to clear out space on my iPhone?

    I have over 1000 photos in my camera roll, and I have saved them to my computer.  Is there an easy way to delete some or all of them to clear out space on my iPhone?

    The quick way is when you imprort them to an app on your computer, usually there is the option to delete everything on the phone that was imported.  If you declined that option, then you have to do it one by one or manualy select in edit mode.

  • I have many duplicates of my pictures on iPhoto there an easy way to delete these?

    I have many duplicates of my pictures on iphoto Is there an easy way to delete these, 23,000 pictures would take years to go through.

    Where are you seeing these duplicates?  In the iPhoto window or via the Finder?  If it's the Finder then you don't have true duplicates.  Each photo in iPhoto will have a minimum of two copies often three.  Then there will be additional faces images for each photo. 
    If you truly seeing duplicates while viewing in the iPhoto window there are two apps, actually one app and one Applescript script, for finding and removing duplicate photos from iPhoto. They are:
    Duplicate Annihilator
    iPhoto AppleScript to Remove Duplicates
    However, do not ever remove files from iPhoto using the Finder.  That will corrupt the library.
