Questions

Does the check change anything on the computer?
No. KDL Diag reads the state of the hardware and the system without changing anything. The optional load test only runs the processor for 16 seconds.
Is Pro a subscription?
No. It is paid once, €19.90, and the licence never expires. The same key works on up to 3 computers, Windows, macOS or Linux.
Which systems are supported?
Windows 10 and 11, macOS 12 or later (Apple Silicon and Intel), and 64-bit Linux (.deb, .rpm, pacman, AppImage).
