Cannot open two ArchiCad files simultaneously

[ostuecker]

Hi. Everyone says that it is possible to open a minimum of two files on archicad. But if I want to do that, it always closes the already opened file to open the second file. 

Do I have to change something in the settings?

I have a Macbook Pro 16" 2021 so that shouldn't be an issue.. also the files are not too big.

There is a setting in the Work Environment to force Archicad to launch a new instance to open a second file, however, this doesn't always work. If you open the first file then navigate to File, Open, select the file you wish to open from Finder browser and then make sure you select the option to 'Launch a New Instance' at the bottom of the window a second instance will open. You can do this for as many files as you want, just make sure that check box is ticked.
