High quality cable but iMac (27" Late 2013) Catalina 10.15.4 and Macbook Pro (13" 2019 2nd Thunderbolt 3 ports) Catalina 10.15.4. I've tried all the troubleshooting options available online and I still can't get my iMac to work in Target Display mode. It's not the seller's fault, I didn't read the description and some internet sources said it worked when clearly it didn't.
