El Capitan and Sierra for Mac and Sfax print driver
With Apple’s most recent releases (specifically El Capitan and Sierra), comes tighter security policies and user protection – meaning third party software like ours is limited to operate in a sandbox environment and unable to use system resources like CUPS printer functions.
As a result, we have found that some Sfax users are now unable to correctly install, and reliably operate, the Sfax print driver on the latest Mac operating systems. At this time we are unable to provide our customers with a Mac print driver for Sfax that works reliably and meets our exacting standards. Our development team is currently exploring other options as we understand this the need for this type of tool.
We suggest you utilize the web portal for your cloud faxing needs. If you have any questions, please submit a support ticket to email@example.com.
