I met a woman called Laura who turned out to be a film maker. She gave me a DVD of her 2017 film Hesperidies and last night I decided to watch it. I don’t have a TV or DVD player so I watch films on my iMac, and if it is a DVD I always rip it using an external DVD drive and HandBrake, the open source video transcoder. Then I can watch it from my hard drive. So I plugged in my DVD drive, opened the shrink wrapped DVD box, and inserted the DVD into the drive. That fired up HandBrake but when I tried to open the DVD it gave an error:
“libdvdcss.2.dylib” cannot be opened because the developer cannot be verified
macOS cannot verify that this app is free from malware
