Wrong Python version with CMake on Mac OS

[ThomH]

Hello, I've got a frustrating error on a fresh install of my environment on Mac OS 13: "Could NOT find Python3: Found unsuitable version "3.9.6", but required is at least "3.10"

The SDK 2.7 have been installed using nRF Connect for VSCode. In the toolchain files I see that Python 3.9 is installed alongside cmake 3.21.
The error is produced after creating the configuration graphically. I've tested other SDKs from 2.4 to 2.7 with the same result.

Do you have a solution? Thanks in advance

Hello,

Which version of the nRF Connect SDK are you using? If you are on main or v2.8.0, you will need to upgrade your toolchain as well. v2.8.0 of the toolchain was just released.

Best regards,

Vidar

Well .. with SDK 2.8, which was released 45 minutes ago, the build is now working. I will not know why the old versions were not functional.

Thanks for your reply

Thanks for the update. The toolchain you were using earlier was for SDK v2.7.0 and does not include the required dependencies for SDK v2.8.0.
