The answer to this question depends on the type of update you are performing. If you are simply upgrading from one version of macOS to another, then no, your data and files should remain intact. However, if you are performing a clean install, then yes &#8211; all data will be erased from your computer and replaced with the new version of macOS. To ensure that your data is safe during a clean install, it is best to back up any important files before beginning the process.<\/p>\n<lite-youtube videoid=\"k6XnvQh3cPc\" playlabel=\"Play: Keynote (Google I\/O '18)\"><\/lite-youtube>\n<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_did_my_Mac_update_and_delete_everything\"><\/span>Why did my Mac update and delete everything?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<lite-youtube videoid=\"xvKyGcSNPBU\" playlabel=\"Play: Keynote (Google I\/O '18)\"><\/lite-youtube>\n<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Does_installing_a_new_OS_delete_everything\"><\/span>Does installing a new OS delete everything?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Installing a new operating system (OS) does not always delete everything from your device. It depends on the type of install you are doing and whether or not you have backed up your data before beginning the installation process. If you are performing a clean install, then it will erase all existing files and settings; however, if you are upgrading an existing version of the OS, then your files and settings may remain intact. To ensure that no data is lost, it is recommended to back up all important files prior to beginning the installation process.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_do_I_update_my_Mac_without_losing_data\"><\/span>How do I update my Mac without losing data?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Updating your Mac is a straightforward process that can be done in just a few simple steps. To ensure that no data is lost during the update, it is important to properly back up your files and settings before beginning. Once you have taken the necessary precautions, you can proceed with following these steps:<br \/>\n1. Open System Preferences and select the Software Update option from the Apple menu at the top of your screen.<br \/>\n2. Check for available updates by clicking on \u201cCheck Now\u201d or \u201cInstall Items\u201d if an update is already available.<br \/>\n3. Select any updates that are available and click on Install to begin downloading them onto your computer.<br \/>\n4. Once all of the items are downloaded, you will need to restart your computer for them to take effect and complete the update process successfully without losing data.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Will_upgrading_to_Big_Sur_delete_my_files\"><\/span>Will upgrading to Big Sur delete my files?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>It is important to understand that upgrading your operating system to Big Sur should not delete any of your files. Apple has made sure of this, as such upgrades are designed to be low-risk and stress-free. Before upgrading, it is a good idea to back up your data so it can be restored if anything goes wrong. If you choose to upgrade, there are several steps you can take to ensure nothing is lost: <\/p>\n<p>1. Create a backup of all important files before attempting the upgrade \u2013 this will give you peace of mind in case something does go wrong during the process.<br \/>\n2. Download the latest version of macOS Big Sur from the App Store, then launch the installer package and follow the on-screen instructions for installation.<br \/>\n3. After installation is complete and your computer restarts, check that all folders and files remain intact before running any apps or programs that require an update due to changes in macOS Big Sur.<br \/>\n4. Once everything looks okay, re-sync cloud storage services such as iCloud Drive or Dropbox so they have access to updated versions of all documents stored within them prior to the upgrade taking place<br \/>\n5. Finally, perform regular backups after updating just in case something goes wrong down the line which could lead you needing to roll back versions at some point in future updates or security patches<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Will_updating_my_Mac_ruin_it\"><\/span>Will updating my Mac ruin it?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Updating your Mac should not ruin it. While there is always a chance of unexpected issues, the majority of updates are successful and beneficial to the performance of your device. To ensure a successful update, there are certain steps you can take prior to updating. <\/p>\n<p>First, make sure that all important documents have been backed up in case anything goes wrong during the update process. This can be done through Apple\u2019s Time Machine system or an external hard drive or other cloud storage service. <\/p>\n<p>Second, check that all applications have been updated before proceeding with the Mac update itself; this will minimize any potential conflicts between apps and the new OS version. <\/p>\n<p>Third, make sure your Mac has enough available disk space for the new system files; if it does not have enough space, try deleting unneeded files and photos or purchasing more disk space from Apple. <\/p>\n<p>Finally, run any necessary software updates provided by third-party vendors to ensure compatibility with the new OS version before beginning installation of the update. Once these steps are complete and you feel ready to proceed with updating your Mac, find instructions online specific to your model on how to initiate an upgrade or contact Apple Support for additional assistance if needed.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Will_installing_new_macOS_delete_my_files\"><\/span>Will installing new macOS delete my files?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The answer to this question is largely dependent on the method used to install the new macOS.

Here are some steps you can take to protect your data when reinstalling macOS: <\/p>\n<p>1.

Check compatibility: Before installing any updates, make sure they are compatible with the version of macOS currently installed on your computer. Outdated versions may not be supported by newer releases and could potentially cause problems down the line if not addressed properly in advance. <\/p>\n<p>3. Uninstall unnecessary apps: If possible, uninstall any applications that are no longer needed before beginning the reinstallation process as this can help reduce time and potential conflicts later on down the road.  <\/p>\n<p>4.
