How do I remove sensitive data?

I want to make a hard copy of my security information, using Numbers and exit Numbers after printing.
How can I be sure that none of my data remains on the machine?
Would using a Guest account do this?
What happens if Time Machine runs in the middle of the process?
Thanks for any help.

Why Lion? You are here in a forum for workstations. Not ideal and for now isn't required until there is an update.
Turn this around, were you using BitLocker beforre? do you use a program now to encrypt data?
On Windows, you could also store data on encrypted VHD just  like FileVault, but you can also run the OS from a VHD that doesn't save changes to the OS - great for doing things like online banking.
Also password protect file(s), encrypt hard drive, don't use a administrator account (which is default for Mac OS) and work in standard account.
As to guest account not saving changes, I think that is what it does.
The only reason to use Lion FileVault2 is for full system encryption, but being new, might also be risky. Of course any good paranoid has ample backup sets.

Disk Utility has had encrypted disk images which can act like a VHD and FileVault without full user account.

  • How do I remove "other" data from my phone?

    I recently tried downloading a movie in the SD format that was around 2gb or so. I had over 2gb of empty spac eon my phone to rent the movie. the movie started to download fine and I left it to download. I went to videos and the rental shows up however it says there isn't enough room to download it. there is no data under videos howver there is over 2gb of added data to my phone under the "other". Itunes continually wants me to download this rental but I can't with 190mb. I'm guessing the movie already downloaded and something went wrong and it wants me to download it again. I did get a refund for the movie but the space it takes up is still there. Does anyone know how can I remove this data? I tried restoring a backup and emailing customer support and nothing has changed.

  • How can I remove safari data from shared iCloud account?

    Before iOS 8 and family sharing I was using a single iCloud account shared among several Apple devices in my household.  Now that we are all using our own separate Apple Accounts I want to delete shared data from other devices that were using my iCloud account.  For example, my wife and I both have data synched with iCloud (the same account) for Safari.  Now that her phone has been switched over to her own AppleID, I want to purge the data stored in my icloud account from her device.  When I open Safari on my phone, I can see a list at the bottom of tabs that my wife had open on her phone at one time in the past.  That list will never get updated now that she is using her own account.  So how do I purge old data from other devices off my iCloud account? 

    If she's on a different account now, Safari data from the previous account should no longer be on her device.  iCloud tabs, on the other hand, will persist from a device that is no longer sharing the account for 14 days, after which they are automatically cleared.  (This is coming from iCloud, not from her device.)  You might try waiting a couple of weeks and see if they aren't automatically removed.
    If you're still concerned, you could always ask her to go to Settings>Safari and tap Clear History and Website Data.  This won't clear her iCloud tabs from your device though; you'll have to wait for that.

  • How Do You Remove The Date Stamp Setting On The Powershot A590 IS?

    The Date Stamp on our Powershot A590 IS was set by accident, and now we cannot seem to remove it. Anyone know how to change this setting, so that the Date Stamp will not be embedded within our photos (it even seems to be showing up on ALL of our pictures, not just the postcard sized ones . . . but those are our biggest problem, as that's the size we tend to use most)?
    Again, I'm not asking how to remove a Date Stamp from a picture, but how to change the settings so that the Date Stamp isn't applied in the first place. 
    Any help would be appreciated; Thanks!

  • How do you remove the date/time stamp from a photo before printing?

    I have one group of photos in an event that have the date and time stamp on them.  I don't know how to remove the date/time stamp before printing. 

    If you have your camera set to imprint the date/time on the photo you can not "remove it - it is a part of the photo - depending on the surounding photo you might be able to retouch it out

  • How do I remove crontab data I set up?

    Hi there,
    I recently edited my crontab so that my external hard drive would automatically mount and unmount once a night for backup purposes. I learnt how to do this from this site:
    http://hints.macworld.com/article.php?story=20070313192221659
    Now I don't need my external hard drive to automatically mount and unmount anymore and I pretty much want to remove the data from the crontab. I'm not sure if it's just a matter of going into it by typing crontab -e and removing the text or if I actually need to delete a file within Mac OS X or something else.
    Thanks for your time and I hope to hear from somebody soon.
    Regards,
    Daniel

    As you guessed, you just use
    crontab -e
    and remove your entry.
    When you exit the editor, crontab will update the daemon that runs cron jobs.

  • How do I remove migrated data?

    I want to remove all that I have migrated to my new MacBook Pro. How do I do this?

    If you use Time Machine or another backup device, you can simply replace a previous version of the software. If you don't use Time Machine or haven't backed up, your options are more limited: change the data manually, or reinstall.

  • 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 do you remove EXIF data from a video shot on an iPhone5s?

    I'm trying to remove location metadata from a video of my daughter before posting to YouTube and can't figure it out.  I tried opening the video in Adobe Premiere and Bridge and both don't display the location data for some reason, they fields are just blank.  But I can see the locaction data if opened in Quicktime or iPhoto, but neither program allows you to edit the EXIF data for some reason.  And any app I find seems to only work on photos and not videos.  Any thoughts?  I'd love to upload this video without revealing our exact location.  Thanks.

  • How do I remove the data symbol on Line Charts in Numbers for iOS?

    When I create a chart with many data points the data symbol gets in the way and hides the line.
    I have done a lot of looking around in the chart format options and searched online but I can't find the answer to this issue.
    Any fixes or suggestions would be most welcome.

    You're welcome.
    In Firefox 4.0 you can drag the icon back in the "View > Toolbars > Customize" window or place it on another toolbar, but that isn't possible in Firefox 3 versions.
