At $3.99 this was an instant buy for me until the App Store told me I couldn't. I think the venn diagram between HN users and those holding off on Tahoe is probably a pretty big overlap. ;-)

Same! I was trying to buy but wasn't able to.

If ever there were a reason to upgrade!

But thats a fair point- I drank the Liquid Glass Kool-Aid----- I'll aim more compatibility the next upgrade

My experience share only supporting the latest OS:

I have launched apps focused on a new feature in the latest OS and regretted it. The # of people who have the latest OS is much smaller than the full install base for much longer than I thought. As a result, my marketing conversion was unnaturally low - people who liked the app idea but couldn't install because they had the wrong OS. This causes two problems: potential users I activated but couldn't convert and this signal gets internalized by the App Store, pushing down future impressions.

Now I always have a fallback implementation of the feature so I can target the prior OS. Both Mac and iOS.

Do you have a mailing list?
