Install rclone macos High Sierra

Hi, the other day I wanted to install rclone on macos (High Sierra) and when I run the command in the terminal:

sudo curl | sudo bash

I get an expired SSL certificate message

% Total % Received % Xferd Average Speed ​​Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- 0:00:04 --:--:-- 0
curl: (60) SSL certificate problem: certificate has expired
More details here: curl - SSL CA Certificates

curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.

Has anyone else had the same problem?

That's because the OS isn't supported and you most likely do not have an updated certificate chain on there.

You can download it or ignore the cert errors.

I would update the OS though if it was me as that's going to problematic.

The iMac mid 2010 hardware allows me to officially install High Sierra at most.
I will look for how to install a chain of certificates.

Trying to use 2010 hardware with an unsupported OS is going to be painful as many things won't work.

Everything you find is going to be a kludge / hack to get around it:
