TeamViewer DEX Client (1E Client) now supports macOS Tahoe

Apple has officially released macOS Tahoe, and we’re excited to announce that the latest TeamViewer DEX Client (1E Client), version 25.9, is fully compatible from day one. This ensures a seamless experience for IT teams and employees upgrading to Apple’s latest operating system.
