With computers, it’s always the same story. You buy a new MacBook Pro or iMac, and it works flawlessly. But, after a while, they may not work the way they used to. Sometimes the performance is slowing down. Or you continually see error messages. Maybe your Mac is frequently crashing. Or you it cannot run your favorite software. In other words, your Mac simply is NOT WORKING PROPERLY.
All these symptoms can be really frustrating. And, you would probably want to start from a clean slate and reset your MacBook or Mac to factory settings.
Macs are known for their simplicity, and they do not suffer from the problems that Windows users regularly report. And, that’s why we love them so much. However, sometimes we come to a moment where our macOS is so baffled that reinstallation or resetting of the system is the only our solution. And, here you can find how to perform it.
Want to Sell or Give Away Your MacBook? Reset it First
We all come to a point when we buy a new Mac and sell or give away our old model. When you are going through this scenario, performing a factory reset is the first thing you should do, before you send your old Mac on its way to a new owner. Firstly, that way you will protect your personal information. And secondly, the owner will get a Mac in a condition closest to never-used.
So no matter if you want to increase your current Mac’s performance or prepare it for the new owner, performing a factory reset on it is recommended. And unfortunately, the reset process is not as simple as we Mac users are used to. But, that fact shouldn’t stop you from doing it, becaus you have this How-to article.
This guide provides you easy steps for resetting MacBook Pro and other Mac computers back to initial factory settings.
Note: This guide can be used for resetting iMac, MacBook, MacBook Pro, MacBook Air, and Mac Pro.
Clone Your Hard Disk Before Resetting Your Mac
When you reset your MacBook or Mac, all the data, and information you have on your hard disk erased. So, if you want to keep your stuff, you need to create a backup. The process of making a full backup of your Hard Disk is called cloning your Hard Disk. When you create a backup, the best practice is to keep 2 local and 2 cloud backups. And, we highly recommend you doing so.
Another good practice before performing a factory reset on your Mac is maintaining a clone. This is a bootable duplicate (clone) of your HDD. The clone is a completely identical copy of your startup drive, and is stored on an external disk. So, you can boot your Mac from it if necessary. And, for creating a true clone of your HD, you need an application and an external hard disk.
What About Time Machine?
If you are using Time Machine on your Mac, then you already have a proper backup. It is not a complete clone, but it has all your applications, information, and other data safely stored in its backups. So, if you decide to use Time Machine only for the backups, make sure you manually backup with Time Machine before performing any of the following steps. If you haven’t done a manual backup on Time Machine before, here is the procedure.
- On your Mac, go to System Preferences and select Time Machine.
- Now, select the checkbox “Show Time Machine in menu bar.”
Once you’ve done it, a Time Machine icon will pup up in the right corner of your menu bar. (near the date and time)
- Click on that icon and choose Back Up Now. Performing that ensures that you have everything backed up in your Time Machine files.
Time Machine Backup OR Drive Cloning
The most noticeable difference between Time Machine backups and Drive Clones is that clones allow you immediate recovery. When using a clone, you can get back to work immediately after a disk crash or bootup volume problems. Just attach your clone disk, restart your Mac while pressing the Option key, choose the clone drive in Startup Manager, and click Return. Now you are back up and running. You can finish any projects or work before you deal with your drive issues. By running on the clone drive, you can replace or repair your main startup disk when your schedules allows.
When you use Time Machine, restoring your files to a new hard disk or repaired HD can take hours, and sometimes even days. Restoring an entire drive from the cloud backup service can take even longer. And, it directly depends on your internet speed.
What About Third-Party Drive Cloning Software?
The internet is full of software that can back up your Mac to an external drive. For example, you can use Carbon Copy Cloner or SuperDuper. They both are popular applications capable of backing up your Mac. Both have been out there for quite a while, and they have a good track record. SuperDuper and Copy Cloner have a simple and easy-to-use interface, and their main focus is cloning. They include clear features for creating and maintaining bootable duplicates.
Carbon Copy Cloner offers a 30-day trial version while SuperDuper comes in 2 variants. One is the basic limited free version. And, the other one a paid one feature-rich version.
If you use Carbon Copy Cloner, you will notice that the cloning process is really simple. You just set your primary hard drive as a source, and the external drive as a destination. When you are done with this setup, click on “Clone.”
When the process finishes, you can boot your Mac from the external HD without any other adjustments. Just restart your Mac and press the “Option” key. If your system boots up, you have successfully created a clone of your hard drive.
Reset NVRAM Before Resetting Your Mac
If you have been experiencing start-up disk selection, screen resolution or volume issues lately, try resetting the NVRAM on your Mac. That may fix your problem.

Aside from the issues, resetting NVRAM is a good idea when preparing your computer for sale or gifting.
What NVRAM is?
Non-Volatile Random-Access Memory or shortly NVRAM is a small amount of your Mac’s memory where your computer stores certain quickly-accessible settings for the Mac Operating System.
