I can’t find team speak client for macOS El Capitan 10.11.6 and some of them says it will work but when i try to open it it says i need version 10.12 or up and i can’t update my mac is someone able to help me to get ts3?
You need an older version of the client.
I don’t know if there’s a simpler way to get it, but what I thinked is you can look for that and find it here
You will need to check dates until you find a version that matches your needs (don’t go too back!) and download that (if the files are still in teamspeak servers, just check if it works)
Edit: i tested it and it allows you to download that
This is the official download page for older versions: Index
You’ll need to check which one is the latest that works for you, but be prepared - older clients may be unable to connect to some newer servers.
