I just tried to install GoldenSequences on two of my computers and got a message I do not understand. The error I saw first was a stream of identical messages like this
```julia
┌ Error: curl_easy_setopt: 48
└ @ Downloads.Curl /Users/julia/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.6/Downloads/src/Curl/utils.jl:36
```
What does this mean? I’m running 1.6.3.
Both are MACs running Monterey. One is Intel. The other is ARM. I did a restart and all seems to be well.

Quoting from [Wikipedia](https://en.wikipedia.org/wiki/CURL):
> **cURL** (pronounced like “curl”, /kɜːl/[[6]](https://en.wikipedia.org/wiki/CURL#cite_note-FAQ,_haxx.se-6)) is a computer software project providing a [library](https://en.wikipedia.org/wiki/Library_(computing)) ( **libcurl** ) and [command-line](https://en.wikipedia.org/wiki/Command-line) tool ( **curl** ) for transferring data using various network [protocols](https://en.wikipedia.org/wiki/Protocol_(computing)). The name stands for “Client [URL](https://en.wikipedia.org/wiki/URL)”
I think julia uses libcurl under the hood for downloading files. I’m not sure why you’re getting such a cryptic error message but I’m guessing you were just having some connectivity issues and they went away after restarting.

That would be great if it’s true. When I got this mess on the Intel machine I got in so deep that I had to download .julia/environments/v1.6 from another computer before I could sort it out. The ARM machine showed the same message 30mins later, but did not cause any problems.

It’s an issue with Monterey:

I think it will be resolved by the next release. In my experience, it is harmless.
