macOS Sequoia with iPhone Mirroring
Following the release of major operating system updates, there are often small issues that crop up that weren’t picked up during the beta-testing process. As expected, this has happened to macOS 15 Sequoia, which was released on September 16.
There are a few reports on Reddit and on Apple’s support forum claiming that some upgraders to macOS Sequoia are having USB port trouble. Drives and chargers plugged into the USB-C ports of a MacBook aren’t being detected, or take a long time to become usable, one Reddit post claims. There are other similar reports on Reddit as well.
