If you plan to sell your Mac to get a brand-new one or to give it away because you've already bought a newer model, you must first erase all your personal files to avoid unpleasant surprises afterwards.
There is a very simple procedure that you should follow if you need to remove all your personal data from your Mac, and it will require you to securely format your computer's hard drive or hard drives if it has more than one (as is the case of Mac Pros).
Apple also describes on their support website what one has to do before selling a Mac, and even though their procedure is quite simple to follow, it doesn't take into account the fact that a formatted hard drive will not prevent the buyer to recover files that you thought are lost forever.
This happens because even though you tell OS X to delete a file from the hard drive, the file will not be completely deleted since the operating system will only remove the memory reference to the file. This allows recovery software to scan hard drives and recover data, a quite helpful feat if you've accidentally deleted any of your files.
Fortunately, there is a way to protect your files from being revived when you part ways with your Mac: securely erasing the hard drive, a process that prevents third parties from recovering your personal data. When you are securely erasing the hard drive, you are telling the computer to overwrite your files with random data two to seven times (OS X supports 2-, 3- and 7-pass secure erasing).
Next, I will describe the entire procedure of completely clearing personal or sensitive data from your Mac, an easy-to-follow four-step procedure that should give you peace of mind once you give away your computer.
Step 1 - Backup
If you decide to securely erase your Mac's hard drive(s), you will first have to back up your information. To do this, you should use the Time Machine app because it makes it very easy to keep a copy of all your important data.
Apple has its own detailed tutorial on how to use Time Machine to back up your data, and you should follow it step by step to effortlessly set up Time Machine, as well as back up and restore your data.
It is important to note that you should always use an external hard drive, a Time Capsule or an OS X Server on your network to back up your data because backing it up on the same Mac means that you will lose all of it once you format the Mac's hard drive(s).
Step 2 - Deauthorize
During this step of the procedure, you will disconnect your Mac from all Apple services you have connected it to.
First of all, you have to deauthorize the Mac from iTunes to prevent it from accessing the content you bought on the iTunes Store, iBooks Store, Mac App Store or the iOS Store in the future.
Next, log out of iMessage by launching the Messages app, going to Preferences > Accounts and clicking on 'Sign out' after selecting your iMessage account.
Afterwards, you will have to sign out of iCloud by going to the menu > System Preferences > iCloud. Here, uncheck Find My Mac and then click on the 'Sign Out' button at the bottom left side of the window. When you sign out of iCloud, all your iCloud data will be removed from your computer, but it will reappear on your new Mac once you sign in using your iCloud account.
Step 3 - Erase
Mac os compatibility apps app. The first thing you have to do is to restart your Mac and enter the Recovery system to format your Mac's hard drive(s).
You do this by going to the menu and clicking the Restart option. Next, hold down and hold down ⌘ + R on your keyboard and release the keys once the Apple logo is displayed on the screen.
After OS X Recovery loads, you have to click on the Disk Utility entry at the bottom of the window. Then, you need to first choose the startup disk to delete your OS X installation, click on Erase tab at the top, select 'Mac OS Extended (Journaled)' as the partition format in the drop-down confirmation dialog that will appear, and then click on the 'Security Options' button.
Here you can choose the option to use when securely erasing the disk, from a 2-pass overwriting of your data, to a 7-pass US Department of Defense standard that will overwrite your data seven times. Needless to say, depending on the number of overwrites, the erasing processing will take longer.
Once you choose the secure erasing option, click OK and then on the 'Erase' button to completely delete all the files on the disk.
If your Mac has multiple hard drives with multiple partitions, you will have to repeat the procedure described above for each of the disks to avoid leaving any sensitive data on any of them.
Step 4 - Reinstall
After you've cleaned your Mac of all your personal files and data, all you have to do is to reinstall OS X by closing Disk Utility and clicking on the 'Reinstall OS X' option in the OS X Utilities window.
Reinstalling OS X is just a matter of following the on-screen directions, and you'll know you're done after the Welcome message appears.
At this stage, you can either configure the Mac and finish the setup process, or you can just power it off by pressing ⌘ + Q and leave it to the new owner to set up the Mac as he likes. https://sysrenew146.weebly.com/how-to-take-apps-and-programs-off-my-mac.html.

Removing programs from a Macintosh can be very easy. In many cases, all you have to do is drag the application's icon to the Trash. Sometimes, though, applications store the files they need to run in other locations on your computer's hard drive, and finding them can take some detective work. If you are used to the uninstall option in Windows, you have a little culture shock — macOS does not have this feature built in.
Why would you want to uninstall a program? For the same reason you occasionally tidy your office or clean your garage. Clutter breeds inefficiency. Applications take up space on your hard disk and can slow your computer. Also, a new version of a program may not work correctly unless you get rid of the old one [source: Ritchie].

Most of the time, uninstalling is this simple:
- Exit the program you want to delete.
- Open the Applications folder, which you'll find by opening a new window in the Finder, or clicking on the hard disk icon.
- Drag the icon of the program you want to uninstall to the Trash.
- Empty the Trash.
When files for the application you want to delete are all stored in one location, dragging the icon to the Trash will take care of most of the work. In Mac talk, apps like this are 'bundled.' To see the files in an application's bundle, click on its icon while holding down the Control key. You should see an option that says, 'show package contents.' Uninstalling applications downloaded from the Mac App Store is even easier — just delete the application from the Applications Folder and its accompanying folder in UserLibraryContainers [source: Tanous].
For some other programs, removal is more complicated. When installed, these programs create files in several locations, often in the System Folder. The first step in removing them is to check the program's documentation to see if there is an uninstall utility. If your program has an uninstall utility associated with it, it may have been installed with the program or included on the disk that came with it. If you downloaded a disk image to install the software, sometimes you'll find an uninstaller there. Running an uninstall utility can make removing a program much easier.
You should be aware that removing an unbundled program by moving it into the Trash can leave behind orphan files on your computer. Preferencefiles are usually small and you might want to ignore them if you're just trying to free up disk space. Background files or support files can be larger, especially for multimedia programs like GarageBand [source: MacRumors]. These files are likely to reside in Library folders in your hard drive or Home folder. They will usually be labeled with the name of the program, like Office or Acrobat, or the developer, such as Microsoft or Adobe. You can search for the relevant names using Spotlight, which is included with the Mac OS. Drag the files you find to the trash to get rid of them [source: Tanous]. .

If searching through obscure corners of your computer for what could be hundreds of files sounds like something a machine could do better than you, you're right. There are plenty of software programs that do just that. They're usually your best bet for really cleaning an app off your Mac, and some of them are free. Popular examples include AppTrap, Appcleaner, and AppZapper.
Some of the files that a program might create on your hard disk are invisible. It may be tempting, especially for neat freaks, to find and delete these files. But some files are deliberately hidden because they are essential to the computer's operating system. Deleting the wrong file could land you in deep trouble [source: Landau]. The best advice is not to go where even experienced techies fear to tread. Uninstall utilities can search out and destroy these files, but doing so on your own invites trouble.

Another important thing to do is empty your Trash when you're finished uninstalling. Moving a program's icon to the Trash doesn't actually remove the files from your hard disk or clear up any space. Only when you empty the Trash is the application really gone.
Here are some other important tips:
- When you install a program, check to see how to uninstall it. Make a note if it has its own uninstall utility or instructions.
- Before you begin any uninstalling process, check to make sure your Trash is empty or contains nothing you might want to save.
- Log on as your computer's administrator whenever you uninstall. If you're uninstalling at work and don't have administrator privileges, you'll have to consult with your tech people [source: Ritchie].
- If you opt for a third-party uninstall utility, look at the features. Some developers charge for their software, but you may not need the bells and whistles. Free utilities may work fine.
- It often makes sense to leave preference files alone. If you ever reinstall the same software, you won't have to set the preferences.
- Suites of software from a developer, such as the Office suite from Microsoft, often share files. Removing the files of one component may affect the others, so it's good to be cautious with these [source: The X Lab].
- If, after you remove a program, the icon is still in your dock, you can get rid of it by simply dragging it off the dock and letting it go [source: Tech-FAQ].
Removing software from your Mac is a lot less of a hassle than cleaning your office or garage. But clearing away computer clutter and making space on your hard disk can be just as satisfying.
