How do I wipe my old IMAC Yosemite?

To wipe your old iMac Yosemite, you will need to create a bootable USB drive, using a second Mac (if available) or a Windows PC (if available). You will then need to launch the iMac in ‘Target Disk Mode’ by pressing the ‘T’ key when turning it on.

Once the iMac is in ‘Target Disk Mode’, connect it to the second Mac or Windows PC that you have already used to create the bootable USB drive.

Once connected, you will need to launch ‘Disk Utility’. This can be done by launching ‘Finder’ (on the Mac) and navigating to the ‘Applications’ folder. Within the ‘Applications’ folder, look for the ‘Utilities’ folder — this is where the ‘Disk Utility’ application can be found.

When in ‘Disk Utility’, select the hard drive of the iMac and wipe it completely by selecting the ‘Erase’ tab and selecting the ‘Mac OS Extended (Journaled)’ option in the ‘Format’ drop-down. You can then choose either ‘Fastest’ or ‘Secure Erase’ from the ‘Security Options’ drop-down menu.

Once the disk has been wiped, you can use the bootable USB drive that you created to reinstall Yosemite on your iMac. Follow the instructions on the USB drive and your iMac will soon be up and running again.

Why doesn t my Mac have Erase all content and settings?

The “Erase all content and settings” button is not available on Mac computers because Apple has a different approach to data erasure than other operating systems. On Macs, users can securely erase all the data on their machine through the macOS recovery system, which will reinstall the OS, but keep user files and settings untouched.

This approach is designed to make it easier to recover data, in case of a system failure or other issue. To accomplish a secure erase, you will have to go through several steps in the macOS recovery system.

This involves holding down the “Command” and “R” keys and releasing them when you hear the startup chime from the Mac. From here, navigate to the “Disk Utility” and choose the “Secure Erase Free Space” option, this will overwrite the old files and settings with zeros, effectively erasing any data from the Mac.

This process, although somewhat more time consuming than a simple “Erase all content and settings” button, provides the Mac user with a higher level of security, making sure that confidential information is removed safely, and not just hidden away.

Will factory reset get rid of activation lock?

In most cases, a factory reset will remove the activation lock from a device. However, it is important to note that if you do not have the Apple ID and password associated with the device, you may not be able to get it back.

For example, if you are selling the device to someone else, you will need the original owner’s Apple ID and password in order to unlock the activation lock. If you don’t have access to either, you will likely not be able to remove the lock.

Additionally, some devices that are running an outdated version of iOS may not be able to be reset, meaning the activation lock may remain.

Why can’t I erase everything on my Mac?

Unfortunately, you cannot completely erase everything on your Mac. Even if you delete all of your data, restart your Mac, and reinitialize your hard drive, you will still be unable to completely erase everything on your Mac.

This is because when you reinitialize your hard drive, certain system files remain on the hard drive, which you cannot access or delete. These system files are necessary for the Mac to operate properly.

Therefore, in order to completely erase everything on your Mac, you would need to use specialized erasure software that is specifically designed to wipe out all of the information on the hard drive.

How do I wipe my Mac clean or sell?

Selling your Mac requires wiping it clean in order to protect your personal data and to make sure the data on the laptop does not make its way to the buyer. Wiping the Mac clean is easier than you may expect, with the option to changing the hard drive or using a built-in program.

If you plan to wipe your Mac clean and sell it, the first step is to back up your data. This includes using Time Machine to make an archived backup of your files. Make sure you transfer these files to an external hard drive or a cloud storage system.

To be thorough, you should double-check that all of your files are backed up.

Once the data is safely stored away, there are a few methods you can use to wipe your Mac clean. Using the Disk Utility app, you can easily erase and reformat the Mac’s hard drive, creating a “blank slate” on which the new owner can install their own version of MacOS.

It’s important to note that this option won’t completely delete all the data, as files can be recovered by the buyer with the right software.

If you prefer a more secure approach, you can opt to replace the hard drive and install a new copy of MacOS on the new hard drive. Doing this prevents the buyer from recovering any of your data. The hard drive can be easily replaced by following any of the many online tutorials that explain how to remove and install a new MacBook hard drive.

Once the Mac is wiped clean, you can proceed to sell it. Be sure to include a note that it is not refurbished or tested for any kind of hardware or software issue. You will also be responsible for any future customer support issues that the new owner may encounter.

How do I wipe my hard drive before recycling Mac?

Before recycling an older Mac, it is important to wipe the hard drive to prevent unauthorized access to your personal data. This process (known as data erasure or data destruction) will overwrite all of the data on the hard drive so that it cannot be recovered.

To wipe the hard drive:

1. Back up your Mac. Before wiping the hard drive, it is important to back up all of the data you would like to keep. Use a cloud-based backup service such as iCloud or Dropbox, or a portable storage device like an external hard drive.

2. Sign out of your Apple ID. In the Apple menu, select System Preferences and then click on Apple ID. Sign out of your Apple ID, then sign out and quit all open applications.

3. Start up in OS X Recovery. Reboot your Mac and immediately press and hold Command+R. This will start up OS X Recovery, allowing you to securely erase the hard drive.

4. Use Disk Utility. In OS X Recovery, select Disk Utility from the Utilities menu. Select the hard drive from the list, then click the “Erase” tab. Enter a new name for the drive and select “Mac OS Extended (Journaled)” as the format.

Select “Security Options” and choose a secure erase type, then click the “Erase” button.

5. Reinstall OS X. Once the hard drive is securely erased, you can reinstall OS X via the Internet Recovery process. Start your Mac and immediately press and hold Command+Option+R. This will start up the Internet Recovery process, which will allow you to reinstall the original version of OS X that came with your Mac.

Once the installation is complete, you can safely recycle or donate your Mac knowing that all of your personal data has been securely erased.

Can hard drives be erased completely?

Yes, hard drives can be erased completely. However, the precise methods for doing so vary depending on the hard drive type and data storage format. Generally, secure deletion techniques involve multiple overwrites with pseudo-random patterns, making the original data indecipherable.

Some hard drive manufacturers also provide built-in secure data erasure functions as an alternative to “traditional” hard drive wiping. Another method to remove hard drive data involves physical destruction.

Professional data destruction services use specialized equipment which can not only overwrite data but also physically destroy hard drive components. This method is recommended by certain organizations, especially those holding sensitive data.

Does factory reset remove all data permanently?

No, a factory reset does not remove all data permanently. While it is designed to erase all of the user information and settings stored on a device, it does not overwrite or destroy the data stored on hard drives.

When a factory reset is performed, all of the user data and settings are erased but the operating system and other system files remain intact. These files can then potentially be recovered using software data recovery utilities.

So, even though a factory reset may appear to have removed all data from a device, there is still a risk that it could be recovered with the right software and resources. Therefore, to ensure that all of your data is permanently removed from the device, it is important to use a reliable data destruction service to overwrite the data multiple times before sending it off for recycling or disposal.

How do I clear my computer to sell it?

If you plan to sell your computer, it is important to clear all of your data first. Here are some steps you can take:

1. Backup all important data. It is crucial to back up your data before wiping the computer so you do not lose anything important. Make sure to keep important documents, photos, videos and other files safe by transferring them to an external hard drive, cloud storage, or another device.

2. Reset the operating system. Depending on the operating system you are using, you can reset it to factory settings to remove all of your account information, installed programs and personal documents.

You may need to refer to your operating system’s instructions or user manual for specific instructions on how to do this.

3. Erase the hard drive. If you want to securely delete data beyond recovery, you can wipe the hard drive completely so that no files are capable of being recovered. This can be done by a third-party software program or you can navigate to the hard drive to erase the information manually.

4. Update drivers and programs. Once the computer is cleared from all data, update any drivers and programs. You should check online for the latest software updates to keep your computer running smoothly.

5. Clean the computer. To make the computer look nicer, you can take the time to physically clean it. Wipe the external parts and remove dust build-up with compressed air.

Once you have followed these steps, your computer should be ready to be sold.
