In fairness, Apple changed their architecture and security policies (Catalina), rendering the software obsolete. So it's more than just some settings. Access on the other hand released their last product in 2009 and have only been maintaining the code base.
When I read these forums, it's like everybody is mad at Access while in fact they should be mad at Apple... They made the changes, they rendered your 2K toys useless if you counted on the integration. Also everyone complaining about buying a new virus ti and not having the integration were negligent on their part for not doing the research.
I'm not sure who that comment was directed at "it's more than just some settings". Absolutely it's Apple who have made significant architectural changes - firstly the move to only supporting 64-bit (which is what this thread is about really) - and then the move to user-mode drivers going forward.
However Access have been completely non-comital around whether they are going to update their Mac software or not. That's unacceptable. Some of us would quite happily pay for them to work on an update.
Also I strongly disagree with your comment around the buyers of a new TI hardware being at fault and negligent if they don't research Mac compatibility. Access should be actively highlighting the Mac compatibility issue. If they aren't then it's Access that is negligent and at fault.
