I did finally manage to get in touch with Micheal David and he sent me a copy of the stacks in question for testing. I tested Click Slider, In Motion, and Triple Play. They all installed without incident when I dropped them on RapidWeaver in the dock, and were immediately amiable inside of Stacks 3, and appeared in the RapidWeaver 6 (and 7) Addons Manager window. Here’s what I saw:
So, to answer why these haven’t appeared in your Stacks Library I think we need to answer: How does your RapidWeaver setup or what you do differ than my RapidWeaver setup and what I did in my experiment.
I can verify that my version of RapidWeaver is close (6.3.8) and my version of Mac OS X is also close 10.11.4. Neither of these minor differences should produce any noticeable changes in behavior in Stacks or RapidWeaver – so I think it’s safe to look elsewhere.
I think the most obvious place to look is: Are we certain these are making it to the real Stacks library folder. The simplest way to answer that is to open a new Stacks page within RapidWeaver and select “Show Stacks Library in Finder” from the Library Gear menu.
This will open up the folder that Stacks is currently using – no matter where it happens to be.
Inside that folder should be a Stacks folder – and inside of that should be the stacks you’ve installed. I think a good thing to do would be to open up those folders and take a screenshot and post it here. Often times folks familiar with how things should look can spot something just from visual inspection of the files.
Here’s what mine looks like after installing just those stacks. See if you can make yours look the same.
Let’s give that a go and work from there.
