Erase all data and reboot?

I'm trading my black macbook to best buy. how do I erase all data so that it's back to factory settings? please i need step by step info

You don't need to zero-out the data unless you're really really paranoid that someone will actually try to harvest your info from the drive...which isn't likely.  Plus, zeroing the data can take hours..even days.
Will I be able to re-install the OSx after this is done?
Yes

  • I can't erase all data and content from my iPhone 4s. It says iCloud account not verified, when it only asks for my Apple ID to erase all data and content.

    It's really been puzzling me, I've never logged in the Apple site on a laptop before - I have been getting the same message 'Unable to verify iCloud account' every time I try and erase all data and content from my iPhone 4s. When I go to iCloud on my laptop and sign in using my Apple ID it signs me in. These are the same log in details I am prompted for when trying to erase all data/content from the phone. If anybody could point me in the direction that would be really appreciated. Thanks

    Hi.
    Yes, I recently changed my Apple ID password - around 2 weeks ago when I bought the phone.
    Does anyone know if you need to do the IOS update to be able to restore all data and content? I have not installed the new update on either of my iPhone 4S's yet.
    The phone I am trying to reset was sold to me by a friend and when it was it had already been reset and it was on the language selection screen.

  • I've jail break Iphone 3GS. i tried to restore setting (erasing all data and media) without connecting to computer/itunes. When it starts it freezes by showing apple logo only. what is the solution.

    Although not illegal, Apple discourages a user from modifying the iPhone OS in any manner, including "jailbreaking".  Apple feels so strongly about this that discussing methods to assist a user trying to either jailbreak or "unjailbreak" an iPhone are prohibited.

  • How to erase all datas and reset default

    How to erase all datas and factory reset in iMac

    Boot into the Recovery HD (restart holding down Command+r). Launch Disk Utility and erase the drive (all data will be gone forever so make sure you have a reliable copy of any valuable data). Quit out of Disk Utility when formatting is complete and select re-install OS X (you'll need an Internet connection).

  • Can i stop the Erase all data and settings process for Iphone 3gs? It has been 4 hours and still not finished!

    Hi, i just want to know if theres any way to just stop the erase all data and settings for my iphone 3gs it has been 4 hours and it still havent finished yet, still showing the black screen with an apple icon. Im getting so frustrated, is there any way to just stop the process and roll back the changes made? Would it do any harm if i press on my home key and power button the same time? Thanks!

    Something has gone wrong, on an iPhone 3Gs the erase all operation should be instantaneous. Disconnect your phone & force it into recovery mode:
    Turn your phone off. Leave the USB cable connected to your computer, but NOT your phone, iTunes running, press & hold the home button while connecting the USB cable to your dock connector, continue holding the home button until you see “Connect to iTunes” on the screen. You may now release the home button. iTunes should now display that it has detected your phone in recovery mode, if not quit and reopen iTunes. If you still don’t see the recovery message repeat these steps again. iTunes will give you the option to restore from a backup or set up as new. In your case, select "new".

    Why do you need to access your email?  To reset the password?
    If you're trying to change the password, you don't need to go to your email.  If you know the answers to your security questions, you can reset it without using an email, as explained in the first section of this article: http://support.apple.com/kb/HT5787.  If you don't, you can contact Apple for assistance by going to https://expresslane.apple.com, then click More Products and Services>Apple ID>Other Apple ID Topics>Lost or forgotten Apple ID password.

  • Had many issues with phone, decided to erase all data and now it won't finish

    Okay here's the rundown of my problem on my iPhone 5 32GB. I can't check currently (you'll understand why later) but I believe it was on iOS 7.1.1 as I know it wasn't the absolute most recent version. First off, my lock button is sometimes unresponsive, a hardware issue and I haven't gotten around to getting that fixed yet. Anyways.
    Today I wanted to open up my twitter app. The instant it opens, everything freezes. I mean everything: screen, lock button, home button, everything. The screen usually shuts off after 90s if I don't do anything, so the screen went black after this time as everything I did didn't register. Now with the screen being black, still no response from most things. The only thing I can do is activate Siri, though the screen still doesn't turn on, just the sound. She couldn't usually hear me, and if she did it would take her about a minute or so to respond. I can still connect to iTunes (windows 8) though so I did that, but I stopped the initial sync. I tried doing the hold both buttons for 10s thing but that didn't work (might be because the lock button is iffy) so I couldn't start recovery mode.
    At this point, I decide the only thing I could do (because no where on Google anyone had a similar problem) is to restore the phone, either to factory or to a backup. When I tried these options in iTunes, it told me that it could not do this while Find my iPhone is active, and to go to settings on my phone to turn it off. I can't open settings with the screen black. I tried going to icloud.com in order to see if I could turn it off from there. The site could find my phone just fine, could make the sound just fine. I could however not remove the device from iCloud unless the phone was turned off (which I again can't do with a black screen).
    At this point, I went to the directory with the backup on my computer and copied it to another location. Then in iTunes I did a sync to create a new backup. Now the only thing that was available for me to do was on the web site to erase all data from the phone as it did not require Find my iPhone to be turned off. Feeling out of options, I went through with it and clicked erase. For some reason, this is the time that the screen decides to turn on. The phone showed the apple logo and a progress bar. The bar progressed quickly at first but then slowed as it neared the end. At this current point, it's been at what appears to be 100% for around an hour with nothing happening. The buttons do nothing, my computer can't see the device so iTunes won't do anything.
    Is there anything else I could try to do or should I just wait it out. My city does have an apple store which I could go to tomorrow but if I could get my phone running tonight that would be great. Also, if I can't do anything and it doesn't budge, if I take it to the store would it cost a lot to fix or (if necessary) replace? It was a birthday gift two years ago, bought without a plan, and I don't think it's still under warranty.

    Hi..thanks for your advice!
    Ok, I am student so buying a new phone is not possible ;( This experience has turned me off Apple anyway! All I did was click yes to their iTunes upgrade prompt asking me if I want to update....and now I don't have a phone and can't access all my backup etc on my iTunes because it seems the only way to get to it is with another iPhone!?
    I can't believe that through the Apple recycling program I could possibly get $50 for this phone because the hardware is perfect but there is no support for this issue...feels like Apple is just trying to force everyone with hacked phone to buy new ones!

  • HT1766 If I erase all data and settings on iPhone 4S will I lose my purchases

    I have a iPhone 4S I bought on December 9th 2012 from sprint and I'm not sure if I will lose all my iTunes purchases like my movies TV shows and TV show seasons some I bought with a gift card and I'm low on gb so I want to know if I backup or reset all data and settings will I lose all my purchases movies apps etc?

    Erasing all Content and Settings completely erases the phone.  Your purchases should be in your iTunes library.  If not, connect your phone to iTunes, make sure your computer is authorized for all Apple IDs used to purchase your media (in Store>Authorize This Computer), then go to File>Devices>Transfer Purchases to transfer your purchases to your iTunes library.  You can then selectively remove media from your phone without erasing the entire phone, and sync it back later as desired.

  • URGENT-Does Erase all Data and restoring from a previously made backup permanently delete text messages after that backup??

    Does restoring from a previously made backup permanently delete text messages after that backup?
    I made a Icloud back up two days ago. I have text messaged and sent emails since. I haven't backed up again yet and I was wondering that if I erase my phone and back up to that Icloud Back up made two days ago, the texts and emails I have sent SINCE then will be permanently deleted? AKA they can never be found again by anyone?

    That is correct you can only get back data that was backed up.
