2021-08-02 19:01:20.398 Syncthing[7417:49189192] Delaying daemon startup by 10.0 s

This is due to clock_gettime not existing on MacOS 10.11.6, which is what I'm using. Given that your stated requirement is "10.10 or later", maybe you could fix this?¹ Thanks.

¹ By which I mean, making it work on 10.11.6, rather than - for example - changing the stated requirements.

[xor-gate]

This issue is related to the already closed #148. As mentioned in the FAQ on the main page you need macOS 10.12 or higher. We will not support lower versions or you need to install the latest supported v1.13.1-1 version. Or if you are up to an adventure you could compile latest syncthing with a golang compiler supporting macOS 10.11 but then your are on your own. Sorry!

[xor-gate]

Forgotten to mention the main page (README.md) has been updated with correct information which macOS version is required.
