Mac OS 10.15 Catalina
As of 10/11/2019, Neat is happy to say that there are currently no compatibility issues with current Neat products in the new Catalina OS. However, we have received some reports that even though there is no issue with scanning, some users still get an error message during scanning stating 'Failed to open a session on the device'.
This error is from your MacOS, not from Neat. It does not prevent you from scanning.
We highly recommend that you do not upgrade to Catalina if you are using a retired Neat product. Retired Neat products are not compatible with Catalina and will cause the retired application to stop working completely.
