Bests & Worsts Reviews from Amazon

I purchased this adapter cable to connect a USB 2 optical drive to an iMac on one of the Thunderbolt 3 ports. The drive reads and writes CDs and DVDs without any problems over the connection. Five stars because "it just works" plus Apple's version of this cable is a lot more expensive. ---------- Update (July 2018): No problems to report, still working after upgrading macOS from Sierra to High Sierra. Update (January 2019): No problems to report. Update (February 2019): Bought a second adapter to use with wired keyboards. No issues so far. Update (June 2019): No problems to report on either adapter. Update (July 2019): Both still working after upgrading to macOS Mojave. Update (March 2020): No problems to report. Update (September 2020): No problems to report. I'm not going to put macOS Catalina on my computer so I don't anticipate any system incompatibilities until at least the release of Big Sur. And if Apple fails to make Big Sur stable and secure, I'm staying with Mojave as long as I can. Update (October 2021): No problems to report (and still on Mojave). Update (July 2022): Both still working after upgrading from Mojave to Monterey.
