macOS by Tutorials has a new name and a new edition!

The book is available for purchase or update at Gumroad.

macOS Apps Step by Step was previously titled macOS by Tutorials and was released in 2022 by Kodeco. Since they transferred the rights to me, I have released two updates under the same name, but now it feels like time to move on from the Kodeco naming convention and give it a name that is more part of my brand. After considering several options, I put a poll on Mastodon and macOS Apps Step by Step was the winner.

If you bought the first edition of macOS by Tutorials from either Kodeco or Amazon, please email me for a 50% discount code.

If you bought a previous edition of macOS by Tutorials from me via Gumroad, version 4 is a free update that you can download from your Gumroad library.

The major changes in this fourth edition include:

• A new title!
• All projects updated to include new features introduced in macOS 26 Tahoe and Xcode 26.
• All projects use Swift 5 or 6 with Approachable Concurrency. Swift 5 is still the default in Xcode but I switched all the projects to Swift 6 and made sure that all the code works for both versions.
• The On This Day app has been re-designed to use a more stable HSplitView instead of the problematic NavigationSplitView.
• Icons are created using Apple’s Icon Composer app.
• The MarkWriter app uses SwiftUI’s WebView to display HTML content and adds the ability to work with and edit selected text.

If you already own the book and have enjoyed it or found it useful, I’d really appreciate it if you could leave a rating or review at the book’s page in your Gumroad library.
