Tower 6 - The Big Sur Update

Table of Contents

With Tower being a native app it has always been very important to us to be in line with the OS design from Apple. Therefore we have been busy to get Tower ready for Apple's next macOS update: Big Sur.

The OS update gave us the chance to tweak Tower's design once again - from icons to the sidebar and toolbar. On top of that the new Apple Silicon Architecture allowed us to improve Tower's performance once more.

Let's take a closer look at the most significant improvements:

App Icon

The first thing you will notice after updating to Tower for Mac version 6 is our new dock icon. With macOS 11 Apple introduces a new design language for app icons with the goal to bring consistency across all platforms. We reworked Tower’s dock icon to reflect Apple’s switch to rounded-rectangle shapes and make Tower fit right in with your other apps on Big Sur.

Full-Height Sidebar

We are also introducing a new full-height sidebar with this release. Sidebars on macOS 11 now extend to the full window height and we wanted to take advantage of that. You will also notice that selected items now feature a rounded-corner appearance.

Toolbar and Navigation Bar

After adapting the toolbar to the new design, we decided to go one step further and remove Tower’s “Navigation Bar” right below the toolbar. This resulted in a much cleaner and calmer UI. We also moved the icons for Services & Bookmarks to the toolbar.

New toolbar design


Across the whole app you will find new as well as redesigned icons. Most prominently Tower's new toolbar and sidebar sport completely new icons based on Apple's new symbol style.

Apple Silicon Architecture

Tower is now compiled with support for the Apple Silicon architecture. In addition, we made sure to get the best performance and battery life from the new Apple Silicon architecture by improving the handling of background tasks. 🚀
