We have used the fixlets for 10.3 and 10.4 in the past.
We are currently working to author our own, but I thought I would check to see if there were plans to release one (or perhaps it already exists and I’m just not seeing it in the console).
Sorry, didn’t read the title on this post! You are correct that we don’t have one for 10.5 just yet. Let me check with the engineers and see if there are any complications to us adding this.
