It crashed on boot, and re-installing macOS didn&#8217;t help as it complained about the file system being damaged, no matter if I reformat (&#8220;erased&#8221; in Apple-speak) or repartition the disk. The built-in Apple Diagnostics tool crashed after about 16 minutes, so I thought I&#8217;d run <a href=\"http:\/\/www.memtest.org\/\">memtest86+<\/a> on the machine. But without a working OS boot, I was unable to get it up and running, and googling for information didn&#8217;t help.<\/p>\n<p>To get it running, I had to create a bootable USB stick, for which I had to find a Windows machine and run their <a href=\"http:\/\/www.memtest.org\/#dowinso\">USB Key installer<\/a>. However, the disk did not show up in the list of boot options when booting the Mac Mini pressing the Option key. To find it, I had to install <a href=\"http:\/\/www.rodsbooks.com\/refind\/\">rEFInd<\/a> on a second USB stick (they have a <a href=\"http:\/\/www.rodsbooks.com\/refind\/getting.html\">USB flash image ready for download<\/a>, so no Windows machine needed).<\/p>\n<p>With both USB sticks in the Mac, booting with the Option key let me select the rEFInd USB stick, which in turn found the memtest86+ stick as a &#8220;Legacy Windows&#8221; image.
