ARCHICAD becomes non-responsive for a few seconds after creating simple elements on macOS 10.13 High Sierra

by Mate Marozsan · updated: 12.11.2017

Affected version(s): ARCHICAD 19, 20 and 21 | Severity: workaround applicable | ID: 237195


After the installation of macOS 10.13 High Sierra, a user may experience an unexpected delay while creating a simple element, for example a wall. Drawing a wall might take up to 2-4 seconds to finish.


ARCHICAD runs over the GRAPHISOFT folder when cache files are created. This results in a slow process because the folder structure contains old data-set that has been converted from HFS+ to APFS.


  1. Make sure that all of your projects are saved/all of the changes are sent and received in Teamwork projects.
  2. In Teamwork projects it is advised to Leave Teamwork Project before applying any changes.
  3. Close ARCHICAD then rename the /Users/<username>/Library/Application Support/GRAPHISOFT  folder (e.g.: _GRAPHISOFT)
  4. It is safer to rename it first because it contains previously created autosaves, local cache, DXF-DWG Translator, IFC Schemes that might be important for a user
  5. Reopen ARCHICAD and check the result of the workaround above.
  6. If the slow performance issue is no longer occurring, the user can copy the important data (e.g.: autosaves, local cache, DXF-DWG Translator, IFC Schemes) if needed from the previously renamed folder to the new GRAPHISOFT (/Users/<username>/Library/Application Support/) folder. The originally renamed folder now can be deleted.
  7. If the Autosave folder is stored in different location determine by looking in the Work Environment (Data Safety & Integrity). Rename it first then handle it as mentioned above. It is recommended to use the Default Location.


We plan to include a fix for this issue in the 8000 Update of ARCHICAD 20 and the 6000 Update of ARCHICAD 21.
