When reinstalling macOS, it is important to be aware of the potential impact on existing files. Generally speaking, a fresh install of macOS will not delete any user-generated data or documents. However, as with any operating system update, it is still recommended that you take a full backup of your hard drive before proceeding with the installation. This way, if anything does go wrong during the process, you can easily restore your files and settings. Additionally, any programs installed after the original OS installation may be removed in the reinstallation process as they are not considered part of the base OS image. Therefore, it is always best practice to make sure all important files are backed up prior to beginning a fresh install of macOS.

Is reinstalling macOS the same as factory reset?
The terms “reinstalling macOS” and “factory reset” are often used interchangeably to describe the process of restoring your Mac to its original factory settings. However, they are two distinct processes that have different results. Reinstalling macOS is primarily focused on replacing the current operating system with a clean version while a factory reset erases all data from the computer, including any user files, applications, and settings. Depending on your needs and preferences, either one can be an effective way to restore functionality or start fresh with your Mac.
How do I reset my Mac but keep files?
Resetting a Mac can be an effective way to speed up its performance, troubleshoot problems, or start fresh with a clean operating system. Resetting your Mac will wipe out any existing files and settings, but it doesn’t have to mean losing all of your data. By following some simple steps, you can reset your Mac and keep your important files in the process.
The steps for resetting a Mac but keeping files are as follows:
1. Create Bootable Storage Device: Obtain an external storage device (e.g., USB drive or hard drive) that is at least 8GB in size and format it as HFS+ (Mac OS Extended). You can do this by connecting it to your Mac computer and opening Disk Utility (found in Applications > Utilities). Once you have selected the external storage device in Disk Utility, select Erase from the top menu bar, then select “Mac OS Extended” from the Format drop-down menu before clicking Erase.
2. Backup Your Files: Open Finder on your computer and open each folder containing important documents that you want to keep after resetting your Mac. Select all of the desired documents within each folder and drag them into the newly created bootable storage device that was created in Step 1 above. This will back up all of these important documents onto the storage device so they can be accessed later after resetting the Mac computer.
3. Reset Your Computer: After backing up all desired files onto an external storage device, restart or power down your computer while holding down Command + R keys simultaneously until you see Apple logo appear onscreen – this will put your computer into Recovery Mode where you will find Utilities window with several options appearing onscreen – select “Disk Utility” option from there and proceed with erasing main drive (usually named “Macintosh HD”) by selecting “Erase” button located at bottom right corner of window – once done close Disk Utility window & proceed further by selecting “Reinstall macOS” option which should appear at top-right corner of screen & follow instructions provided onscreen for completing installation process successfully without losing any saved data during whole procedure itself!

Does installing new OS delete everything?
Installing a new operating system (OS) can result in data loss depending on the type of installation process you choose. In most cases, if you choose to perform a clean installation of your OS, all of your existing files and programs will be deleted. However, many modern operating systems offer options for performing an upgrade which allows users to keep their existing data while still installing the latest version of the OS.
If you’re considering an upgrade or clean install of your OS, it’s important to understand how each method works so that you can make an informed decision about which approach is best for your situation.
Clean Installation: A clean installation requires that all existing files and programs on the computer be deleted prior to installing the new OS. This method is typically used when one wants to start with a completely fresh system without any pre-existing software or data. This can also be done after a computer has been infected with malware as it may help ensure that all malicious software has been removed from the system before reinstalling the OS.
Upgrade Installation: An upgrade installation allows users to keep their existing data and applications while replacing only certain components of their current operating system with newer versions provided by the new OS they are upgrading to. This method is often preferred by people who want to retain access to their existing documents and programs while still taking advantage of features available in newer versions of their chosen operating system.
