Dear SageMath Support Team, 

I'm asking a question here because ask.sagemath.org seems to be down. 

I'm unable to install Sage successfully so can you please help? 
I downloaded SageMath via https://www.sagemath.org/download.html, extracted it and in my terminal I went to the directory of SageMath and typed ./sage (which is what I gathered from another support conversation). However, I face the following error Apple threw an error that "....[dot]so" cannot be opened because the developer cannot be verified." Attached are the two errors I faced. 

I would really appreciate it if you can please help me figure out a successful SageMath installation. Eventually, I also need to install Normaliz which I gather is done by "sage -i normaliz' or 'sage -p normaliz' . 

Thanks so much in advance!

you either need to permit installation of non-notarised applications, or use
or use Conda, or use Homebrew
(or build from source)

In a terminal, run the following commands:
```
$ xattr -cr /Applications/SageMath
```
This will clear the extended attributes of
all the files in /Applications/SageMath
and hopefully that will allow you to run it
without Apple's Gatekeeper interfering.

Thanks so much! I installed SageMath from https://github.com/3-manifolds/Sage_macOS/releases and it seems to be working fine.
