Greetings,
Visiting the macOS downloads page today (Audacity ® | Download for Mac OS) the checksums are all wrong - verifying the downloads for all the DMGs fails. When I went to check to see if the same problem existed for 3.6.2 (Old Audacity versions download), I found that the SHA256 checksums for macOS 3.6.2 releases were the same as what are listed for 3.6.3, and that validating 3.6.2 DMGs worked. I have to assume that the (presumably manual) process for posting 3.6.3 to the web failed to include posting updated SHA256 checksums. Please fix this!
Cheers,
