Code Rebel Corp. issued an update on its impending release of iRAPP for OS X El Capitan 10.11.1. As mentioned previously, the company made the following specific changes to iRAPP to support El Capitan: (1) the remote login behavior updated to meet El Capitan security standards and in some cases enhanced to improve the system interaction with iRAPP; (2) the network subsystem was improved and optimized for better performance in secure remote scenarios; and (3) all server components were revamped to meet Apple's System Integrity Protection requirements. Mac's OS X El Capitan, released on September 30, 2015, has significantly improved performance, spotlight search, multi-window management, metal graphics technology, as well as a revamped notes app, pinned sites and tab mute for safari.

The OS X El Capitan 10.11.1 update improves the stability, compatibility, and security of Macs. Other highlights include the improvement of VoiceOver reliability and addition of over 150 new emoji characters with full Unicode 7.0 and 8.0 support.
