A common question I get asked is how to easily make bootable images on USB drives from an ISO or img file on a Mac. I use the open source software <a rel=\"noreferrer noopener\" href=\"https:\/\/www.balena.io\/etcher\/\" target=\"_blank\">balenaEtcher<\/a> as part of this process purely because it makes it so easy, so make sure it&#8217;s installed ahead of using this guide! I&#8217;d like to point out, that whilst these instructions are based on my experience with MacOS, there is also a version of the balenaEtcher software available for Windows\/PC and Linux. <\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"has-text-align-center wp-block-heading\">Instructions<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Open <a href=\"https:\/\/www.balena.io\/etcher\/\" target=\"_blank\" rel=\"noreferrer noopener\">balenaEtcher<\/a> from your applications directory on your Mac.<\/li>\n\n\n\n<li>You will first want to click &#8220;Flash from file and select the image you want to use.\n<ul class=\"wp-block-list\">\n<li>In this example I was using <a href=\"https:\/\/www.pfsense.org\/\" target=\"_blank\" rel=\"noreferrer noopener\">pfSense<\/a>, but it can also be used for any image including creating an SD Card for a <a href=\"https:\/\/www.raspberrypi.org\/\" target=\"_blank\" rel=\"noreferrer noopener\">Raspberry Pi<\/a>. <\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"416\" data-attachment-id=\"1708\" data-permalink=\"https:\/\/www.thebigbluehouse.org\/site\/creating-a-bootable-usb-from-an-iso-on-a-mac\/usb-iso-1\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.thebigbluehouse.org\/site\/wp-content\/uploads\/2022\/12\/usb-iso-1.png?fit=1824%2C1184&amp;ssl=1\" data-orig-size=\"1824,1184\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"BalenaEtcher Interface &amp;#8211;
