macOS Catalina 10.15.6 Successfully Fixes USB 2.0 Issues Experienced by 2020 MacBook Pro and MacBook Air Users
macOS Catalina 10.15.6 successfully fixes a frustrating bug that prevented some USB 2.0 accessories from working properly with 2020 MacBook Air and MacBook Pro models, according to MacRumors readers and users on Reddit.
Apple in the release notes for the macOS Catalina 10.15.6 update said that the update "resolves an issue where certain USB mouse and trackpads may lose connection," and people who were experiencing that particular problem have confirmed that their accessories are now able to successfully connect.
The bug was first noticed earlier this year by MacBook Air and MacBook Pro users who purchased one of the new 2020 machines. The Mac notebooks were unable to properly work with USB 2.0 accessories connected to their machines through hubs or adapters.
Problems included lost connections, freezes, and a failure to work entirely, and those affected were unable to find any kind of fix with methods like SMC resets, safe mode, Disk Utility repairs, and more. The only suitable fix was using a more expensive Thunderbolt 3 hub instead of a USB-C hub.
Though Apple's release notes mention mice and trackpads, the problem affected all kinds of devices, including keyboards and other accessories, though it appeared to be limited to USB 2.0 devices rather than USB 3.0 or 3.1 accessories.
There have been numerous reports from those who were experiencing the issue that confirm macOS 10.15.6 addresses the issue for all kinds of accessories. The fix doesn't appear to have been implemented in macOS Big Sur, however, so some users may still run into USB issues on the newest update until Apple adds the fix to Big Sur as well.
