Power User Tips for Unity Hub 2.4.5

Maximize your productivity with these lesser-known tricks.

1. No "Hub 3.0" UI Overhaul

Unity Hub 3.0 introduced significant UI changes that many veteran developers found disruptive—moving the project grid, hiding the "Installs" tab, and aggressive dark mode changes. 2.4.5 retains the classic, muscle-memory-friendly layout.

What it is

Unity Hub 2.4.5 is a version of Unity’s launcher and management app that centralizes Unity Editor installs, project management, account/sign-in, and module/component installs (platform build support, documentation, etc.). It streamlines switching between editor versions, creating new projects from templates, and managing licenses.

Known Issues in 2.4.5 (Still present):

• On Linux (Ubuntu 20.04), window focus sometimes fails after launching an Editor.
• The "Learn" tab loads slowly on first launch.

1. The License Activation Flow (That Actually Made Sense)

Modern Hub versions sometimes bury the "Manual Activation" option behind a menu maze. In 2.4.5, the licensing tab was straightforward:

• Plus/Pro seats activated with a serial key instantly.
• Educational licenses linked without forcing a browser refresh loop.
• Free Personal required no nagging "Sign in every 3 days" popup.

1. Launch the Unity Hub and click on the Installs tab.
2. Click on the Add button to install a new version of Unity.
3. Select the version of Unity you want to install and click Next.
