@ghislainpiot What do you think about fixing the version of the macos image templates?

@Seppli11 You were investigating this I think

I haven't actually started investigating this yet.
There was an update to the macos container yesterday (see here), so there is a decent chance that this is related. I think it would be worth trying.

A note about the macos workers: There are only a limited number of workers available and they are only available during working hours. Because of this, there is an only_if clause for the macos build to restrict the tasks to run only once a day with a cron job. For debugging's sake, this only_if can be removed. It's possible that it takes quite a while for the job to start. If this is the case, the job mustn't be restarted as this puts additional strain on the infrastructure. What is most likely happening is that there is no free macos worker available.

So the macos task hasn't actually ran.

Thanks for investigating this issue.
I'm still a bit puzzled why changing the macOS version should make a test fail.

But for now, this will make master green again, so LGTM 😁 !
