The contents of the disk will be encrypted, and without the password, no one can access them. Its function is similar to BitLocker To Go on the Windows operating system. This tool encrypts the data on the removable drive to provide higher data security.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"229\" src=\"https:\/\/www.isumsoft.com\/it\/wp-content\/uploads\/2019\/01\/encrypt-usb-drive-on-mac-1.png\" alt=\"Encrypt USB disk on Mac\" class=\"wp-image-8492\" srcset=\"https:\/\/www.isumsoft.com\/it\/wp-content\/uploads\/2019\/01\/encrypt-usb-drive-on-mac-1.png 600w, https:\/\/www.isumsoft.com\/it\/wp-content\/uploads\/2019\/01\/encrypt-usb-drive-on-mac-1-300x115.png 300w, https:\/\/www.isumsoft.com\/it\/wp-content\/uploads\/2019\/01\/encrypt-usb-drive-on-mac-1-80x31.png 80w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<p>Connect the USB flash drive to your Mac and find its disk icon on the desktop or Finder sidebar, then right-click and select <strong>Encrypt &#8220;[USB stick name]&#8221; <\/strong>from the context menu.<\/p>\n\n\n\n<p><strong>Note:<\/strong> If you do not see the &#8220;Encryption&#8221; option in the drop-down menu, your USB flash drive has not been <a href=\"https:\/\/www.isumsoft.com\/computer\/format-external-drive-using-exfat-for-mac-windows.html\">formatted using the GUID partition map.<\/a> To resolve this issue, you need to erase and <a href=\"#opt2\">encrypt the USB drive in Disk Utility<\/a>.<\/p>\n\n\n\n<p>Enter your password, verify it, add a meaningful password hit if needed, and then click <strong>Encrypt Disk<\/strong> to start the encryption process.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"305\" src=\"https:\/\/www.isumsoft.com\/it\/wp-content\/uploads\/2019\/01\/enter-encryption-password.png\" alt=\"Enter the encryption password\" class=\"wp-image-8468\" srcset=\"https:\/\/www.isumsoft.com\/it\/wp-content\/uploads\/2019\/01\/enter-encryption-password.png 600w, https:\/\/www.isumsoft.com\/it\/wp-content\/uploads\/2019\/01\/enter-encryption-password-300x153.png 300w, https:\/\/www.isumsoft.com\/it\/wp-content\/uploads\/2019\/01\/enter-encryption-password-80x41.png 80w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<p>You may have to wait several minutes for the contents of your disk to be encrypted, depending on the size of your drive and its speed.<br> <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to encrypt external hard drive on Mac without erasing in Disk Utility<\/h2>\n\n\n\n<p>To encrypt and protect a USB disk with a password using Disk Utility, you must first erase the disk.
