The Citrix Receiver for Mac team is working on product updates to support the upcoming release of
macOS Sierra (macOS 10.12) in Fall 2016. Citrix is committed to provide zero-day compatibility for Receiver for Mac when Sierra is generally available. Zero-day compatibility means Receiver for Mac will operate with the new operating system platform from Apple at release.
In addition to zero-day compatibility, Citrix is reviewing new features that take advantage of Sierra. We will keep our customers informed as we learn more about the changes needed to support any of the new features.
The Sierra beta is available to the general public. Based on our early assessment of the current beta, we are aware of issues making ICA connections over SSL. Citrix has started to fix gaps and areas of incompatibilities with Sierra to ensure our commitment to Zero-day compatibility.
The next version of Receiver for Mac should be available very soon. It does not suffer from the SSL issue on Sierra. Be aware however that even after the next version is released, Sierra is still not a supported platform. If Apple releases a new Sierra beta that causes Receiver for Mac to stop working, there is no guarantee that we will release a fix before the official release of Sierra. Citrix recommends that our customers not install the Sierra beta.
