He is a creative designer who works across multiple devices, frequently switching between Mac and Windows systems as part of his daily workflow. One day, while using the HKS0802A1U KVM with his Mac, he noticed that the keyboard was no longer recognized—although everything worked perfectly when connected to his Windows machine.
This unexpected issue disrupted his workflow and slowed down the fast transitions required for his design work.
He reported the problem to the TESmart support team, providing detailed system information and a clear description of his usage scenario. After receiving the ticket, the team quickly reproduced the issue and identified compatibility differences between older hardware models and newer operating system environments.
Through in-depth analysis, the team confirmed that this was a potential compatibility issue between the older model and macOS Sequoia 15.5.
Within a short period of time, the team completed a targeted software optimization and firmware update, while keeping the designer informed of the progress throughout the process. After the update, the keyboard was once again recognized correctly on the Mac, restoring a smooth and efficient multi-device workflow.
Upon receiving the updated device, the designer shared his feedback enthusiastically:
“Thanks to their fast optimization and timely updates, the issue was resolved in no time. I’m impressed by TESmart’s commitment to supporting older products and providing lifetime technical assistance—truly a company that cares about the full lifecycle of their products.”
This feedback became a valuable reminder for the team: even discontinued products can face new challenges as operating systems evolve. Inspired by the designer’s experience, TESmart further strengthened its maintenance and optimization processes for legacy models—ensuring reliable support throughout the entire product lifecycle, and enabling users to stay productive even in demanding, multi-device work environments.
