By 8.45am, I couldn&#8217;t get my 12&#8243; MacBook to display out via HDMI or VGA to the projector, so I ran back to the room to get my 15&#8243; rMBP instead.<\/p>\n<p>Later on, I ran the <a href=\"https:\/\/support.apple.com\/en-us\/HT201257\">Apple Hardware Test<\/a>. Or what it&#8217;s called now, <a href=\"https:\/\/support.apple.com\/en-sg\/HT202731\">Apple Diagnostics<\/a>. Everything came back just fine, which seemed odd.<\/p>\n<p>The best fix seemed to then be <a href=\"https:\/\/support.apple.com\/en-us\/HT204063\">resetting the NVRAM<\/a>. That didn&#8217;t improve things, so I had to <a href=\"https:\/\/support.apple.com\/en-us\/HT201295\">reset the System Management Controller (SMC)<\/a>, and voila! everything seemed to work thereafter.<\/p>\n<p>In the years of using Apple hardware, I have to think this is the first time I&#8217;ve had to do this. I guess the presentation pro-tip here is always carry a backup presentation device (I might going forward get the relevant dongles for the iPad to run a presentation too).<\/p>\n<div class=\"sharedaddy sd-sharing-enabled\"><div class=\"robots-nocontent sd-block sd-social sd-social-icon-text sd-sharing\"><h3 class=\"sd-title\">Share this:<\/h3><div class=\"sd-content\"><ul><li class=\"share-email\"><a rel=\"nofollow noopener noreferrer\" data-shared=\"\" class=\"share-email sd-button share-icon\" href=\"mailto:?subject=%5BShared%20Post%5D%20When%20your%20Mac%27s%20display%20out%20stops%20working&body=http%3A%2F%2Fwww.bytebot.net%2Fblog%2Farchives%2F2017%2F07%2F17%2Fwhen-your-macs-display-out-stops-working&share=email\" target=\"_blank\" title=\"Click to email a link to a friend\" data-email-share-error-title=\"Do you have email set up?\" data-email-share-error-text=\"If you&#039;re having problems sharing via email, you might not have email set up for your browser.
