What are the system requirements for KaleidaGraph for Mac?
Version 5: OS 10.14 or later. Includes support for the M1 chip.
Version 4.5: OS 10.4 – OS 10.14.
150 MB of free hard disk space is recommended.
Note for OS 10.13 users: Version 5 will run under OS 10.13 but you may get an error that the app is damaged due to a problem related to GateKeeper. You can get around the issue by opening Terminal and running the following command:
xattr -cr /Applications/KaleidaGraph™\ 5.0/KaleidaGraph.app
This will remove some of the attributes of the application and allow it to run.
For the demo version, use xattr -cr /Applications/KaleidaGraph™\ 5.0\ Demo/KaleidaGraph.app
