It has happened again. The auto update installs the new version 3.14.0 without check whether the system requirements are met.
When you update, the error message only appears when you start the client. Then you have to get the old version again and install it manually.
As of version 3.10., only macOs 12 or higher is supported.
The version 3.14.0 has probably a wrong description of the System requirements:
macOS 11.4+ (64-bits only)
The last release 3.9.4 is from Sep 6, 2023. I have already carried out several updates in 2024 and had no problems.
Tested with macOs 11.7.10
