The new version of macOS (10.15, Catalina) comes out in a few days and will no longer support 32-bit apps. The most recent version of SmartPSS I've been able to find is DH_SmartPSS_Eng_Mac_IS_V2.00.0.R.20180507_CodeSign. Unfortunately this is still a 32-bit only app, meaning it won't work for the majority of Mac users who will upgrade in the coming days.
Is there any indication that Dahua is working on a 64-bit build for Mac?
Are there similar apps that I should consider switching to?
