If you find any bugs, please use the contact form to report the issues.
Don't forget to include your Mac model and the VitalSigns version you are using.
You can right click the VitalSigns symbol in the Status Bar to open the Quick Menu. Then click About to get the version number.
This is due to a recent change in the app's version number format. Just download the latest version here. Once you have the latest version installed, the problem will go away.
Sometimes the Swap reading doesn't match the value in the Activity Monitor, especially on machines with 8GB RAM. I'm currently investigating this issue, and it will be addressed in a future update.
Currently, VitalSigns detects CPU, GPU, SoC, Battery, PMU and SSD temperature sensors on M1-based systems. Fans on the M1 MacBook Pro and M1 Mac Mini are not detected, though. This will be fixed in a future update.
