Question: Does latest OS release (High Sierra) prevent the use of thumb drives?
Does the latest version of OS (High Sierra) prevent the use of thumb drives?
I use an accounting system, and keep my data files on a thumb drive for security. Since upgrading to the latest Mac OS (High Sierra 10.13.1) both my financial app and Finder cannot open my thumb drives.
Mac mini (Late 2014), iOS 10.3.3
