We have released Hotfix 5 (build 4056) for ArchiCAD 15. It fixes important Teamwork and IFC related problems, provides solution for crashes and documentation issues. It also improves display quality on Mac computers with HiDPI display.
The Hotfix is currently available through the automatic update system for INT, USA, AUS, NZE, GER, AUT, NED and SWE language versions. Other language versions will be enabled as they pass QC.
