I have 2 Macs, on the older one running OS 10.10.5, neither Poser 8 or 10 can access the library. I have installed Flash several times and can't access the library. My new computer, running OS 10.15.1, I tried to open Poser 10 and I get a message : The developer of this app needs to update it to work with this version of MacOS. I need advice on how to solve this problem, I really want to get it working on the new computer. Thanks.
