Q: How to remove previous owner's Apple ID request from App Store?

Find My iPhone Activation Lock- Removing a device from a previous owner’s account

If you cannot resolve this, then return the phone to the vendor and get your money back if that is possible. Otherwise, you have an expensive paper weight.

It sounds as if you have apps that were downloaded by the previous owner. Did you not wipe the device clean before using it? Apps are locked to the Apple ID used to purchase/download them. Delete the apps in question and download them with your Apple ID.

If it is Activation you are getting this request from, then the information that Kappy provides is what you need to know.

You must uninstall the app from the mac and then re-install the app using your own Apple ID.

F4 -> Click & Hold the app then click the X on the app's top left and confirm deletion.

Check to see what log in is being used for the App Store. If it is the previous owner's then sign out and then sign in with yours. If things were downloaded with the old owner's Apple ID, then you will have to delete them and download with your Apple ID to be able to update them.

If it's asking for a previous owner's Apple ID, then your machine wasn't wiped clean.  There are things that need to be done to properly transfer a computer to another user.  They apparently were not done.  The only way software can end up on your machine with a different Apple ID is if you logged in with said Apple ID and downloaded it or the previous owner did and you didn't erase the hard drive when you first received it.

At the moment you have no iPhoto installed, thus there is nothing to update.  You either have to purchase the iPhoto app, which currently requires Yosemite, or you have to reinstall the iPhoto app from your software restore discs or from an iLife disc.  If you don't have access to either of these things, then you will be unable proceed.  Please note that iPhoto will soon be removed from the App Store to make way for the new Photos app, so your window of opportunity for getting iPhoto as an app is quickly disappearing.

Do you have any Apple system restore discs for your computer?  Do you have the retail iLife disc?  How old is your computer... meaning, does it use internet recovery in lieu of system restore discs?

Before buying a second-hand computer, you should have run Apple Diagnostics or the Apple Hardware Test, whichever is applicable.

The first thing to do after buying the computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.

How you go about it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.

It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.

1. If you don't own another Mac

a. If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller—not from eBay or anything of the kind. If the machine is very old and has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.

b. If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for a MacBook Air. You should have received the media from the original owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.

To start up from an optical disc or a flash drive, insert it, then restart the computer and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.

c. If the machine shipped with OS X 10.7 or later, you don't need media. It should start up in Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.

d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.

2. If you do own another Mac

If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to prepare a USB device, then start up the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can start from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.

3. Partition and install OS X

a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.

b. Launch Disk Utility and select the icon of the internal drive—not any of the volume icons nested beneath it. In the  Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.

c. An unusual problem may arise if all the following conditions apply:

          OS X 10.7 or later was installed by the previous owner

          The startup volume was encrypted with FileVault

          You're booted in Recovery mode (that is, not from a 10.6 installation disc)

In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.

d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.

e. Run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the original owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed—you have to repurchase them.

4. Other issues

a. If the original owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're irrevocably linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.

b. If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to  authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.

c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information. The setup limit doesn't apply to Apple ID accounts used for other services, such as the iTunes and Mac App Stores, or iMessage. You can create as many of those accounts as you like.
