This can fix software failures and restore operation if the device does not boot. There are three ways to work with the system:<\/p>\n\n\n\n<ul><li>update it;<\/li><li>reinstall it in place;<\/li><li>format it.<\/li><\/ul>\n\n\n\n<p>An update installs the latest version of macOS through the interface of the running system. Files, apps, and settings remain unchanged.<\/p>\n\n\n\n<p>An in-place reinstallation does not require deleting everything. You will hardly notice any significant changes \u2014 the system will simply reinstall damaged or missing system files.<\/p>\n\n\n\n<p>Formatting, or a clean OS installation, completely erases the information from the drive. Recovery mode helps reinstall the system or restore data from a Time Machine backup.<\/p>\n\n\n\n<h2><a><\/a>Preparing Before Reinstalling macOS<\/h2>\n\n\n\n<p>Before reinstalling macOS, prepare the device. The instructions are simple:<\/p>\n\n\n\n<ol type=\"1\"><li>Create a backup in the cloud or with Time Machine in Settings. This will help in case of a failure.<\/li><li>Check the OS version <a href=\"https:\/\/support.apple.com\/en-ge\/122867\">compatibility<\/a>. For example, macOS 27 will be released this autumn, and devices with Intel processors will no longer receive it.<\/li><li>Check the quality of your internet connection. You can use Wi-Fi or a wired connection.<\/li><li>Make sure that you have access to your Apple ID and that your passwords and keys are saved.<\/li><li>Deactivate Find My and sign out of the cloud if you plan to sell the device later.<\/li><li>Prepare a bootable USB flash drive if you are using an external installer.<\/li><li>Download the <a href=\"https:\/\/support.apple.com\/en-ge\/101578\">installer<\/a> from the App Store if you plan to install macOS from a USB flash drive.<\/li><\/ol>\n\n\n\n<p>These tips will help you avoid problems during reinstallation and keep all your data in place.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"768\" src=\"https:\/\/ispace.ge\/blog\/wp-content\/uploads\/2026\/07\/Kak-pereustanovit-macOS_-poshagovaya-instruktsiya-_-Foto-2-1024x768.png\" alt=\"\" class=\"wp-image-8682\" srcset=\"https:\/\/ispace.ge\/blog\/wp-content\/uploads\/2026\/07\/Kak-pereustanovit-macOS_-poshagovaya-instruktsiya-_-Foto-2-1024x768.png 1024w, https:\/\/ispace.ge\/blog\/wp-content\/uploads\/2026\/07\/Kak-pereustanovit-macOS_-poshagovaya-instruktsiya-_-Foto-2-300x225.png 300w, https:\/\/ispace.ge\/blog\/wp-content\/uploads\/2026\/07\/Kak-pereustanovit-macOS_-poshagovaya-instruktsiya-_-Foto-2-768x576.png 768w, https:\/\/ispace.ge\/blog\/wp-content\/uploads\/2026\/07\/Kak-pereustanovit-macOS_-poshagovaya-instruktsiya-_-Foto-2-1536x1152.png 1536w, https:\/\/ispace.ge\/blog\/wp-content\/uploads\/2026\/07\/Kak-pereustanovit-macOS_-poshagovaya-instruktsiya-_-Foto-2.png 1674w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2><a><\/a>Ways to Reinstall macOS<\/h2>\n\n\n\n<p>macOS can be installed in several ways.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>Method<\/strong><\/td><td><strong>Advantages<\/strong><\/td><td><strong>Disadvantages<\/strong><\/td><\/tr><tr><td>From a bootable USB drive<\/td><td>Suitable for quickly reinstalling the system on several devices at once<\/td><td>You need to create a bootable drive on a working device beforehand<\/td><\/tr><tr><td>Through macOS Recovery<\/td><td>No USB drive or installer is required \u2014 everything is already built into the Mac<\/td><td>The version that was installed on the drive will be installed<\/td><\/tr><tr><td>Through the built-in installer or App Store<\/td><td>Suitable for updating the system over the existing version<\/td><td>The drive cannot be completely erased<\/td><\/tr><tr><td>From an external drive<\/td><td>Convenient for testing beta versions<\/td><td>An external drive is required<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>You can choose the option yourself depending on the situation.

If the device freezes on the Apple logo, force restart it and begin the recovery process again.<\/p>\n\n\n\n<p>If you do not want to deal with the details of reinstallation, contact one of the authorized <a href=\"https:\/\/ispace.ge\/en\/isupport\">iSupport<\/a> service centers. They are located in Tbilisi at 12 Tsintsadze Street. Our experts will offer a solution based on your goal.<\/p>\n\n\n<style>\n\tdiv#products_6a6dad285c947{\n\t\tdisplay: flex;flex-wrap: wrap;padding: 20px 0px;\n\t}\n\tdiv#products_6a6dad285c947 > div.prodwrap{\n\t\tdisplay:flex;
