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

No, but unless they are formatted for use with a Mac they won't work. How are yours formatted?

John, I have been successfully using a thumb drive formatted for the Mac with my financial app. I have recently installed the High Sierra 10.13.1 update on my Mac mini. I also installed an update to my financial software. However, following those two changes, my thumb drive clouded not be opened either by the financial app or Finder.


Since re-starting the OS twice in the last hour and posting my question, in the past five minutes now I can use the thumb drive! I changed security to encrypt my hard drive, but made no other changes to the OS or financial app in those two restarts.


Thanks for your quick response.


Bill
