Thank you Y-Phil for your answer!

But, now I've upgraded may mac to the last sonoma and poser13 doesn't work anymore on mac. Maybe I've to install a prallells-desktop win-virtual-machine to use poser on mac in the future or build a ventura version on a extern harddis. (that works on mac with all the long forgotten drivers). The other alternatives were to buy a win-pc or to change to daz (that still works without problems). Are there any advices?
