On what operating systems can I run KaleidaGraph?

Mac version:

KaleidaGraph v5.5 will run on OS 12 (Monterey) or later and supports the M series chips.

KaleidaGraph v5.0 will run on OS 10.14 (Mojave) or later and supports the M series chips.

KaleidaGraph v4.5 will run under OS 10.4 up through OS 10.14 (Mojave). This is a 32-bit version that will not run under OS 10.15 (Catalina) or later.

Windows version:

KaleidaGraph v5 and later will run on Windows 10 (64-bit) or later.

If you run into a problem with v4.5.0 – v4.5.3, download a v4.5.4 updater from the Software updates page. For even older versions, you would need to buy an upgrade to the current version.
