Mac computers fully support .ttf files through the native font management app: Double-click the downloaded geetanjali.ttf file.

Mac users can also use Geetanjali font inside design software like Adobe Photoshop, InDesign, or Microsoft Word. Double-click the downloaded Geetanjali.ttf file.

The macOS application will automatically open a preview window. Click the Install Font button in the bottom right corner. Technical Considerations: Legacy vs. Unicode

For the Devanagari script (used for Hindi, Marathi, Sanskrit, etc.), the most popular Unicode fonts are and Nirmala UI (both included with Windows), and the open-source Lohit Devanagari and Baloo fonts. For Assamese specifically, Solaiman Lipi is a highly recommended open-source Unicode font.

Despite being a non-Unicode (ASCII-based) font, Geetanjali is preferred by many professional DTP artists in Assam and West Bengal.
