Is your Mac up to date with the latest version of the Mac operating system? Is it using the version required by a product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.
If your macOS isn't up to date, you may be able to update to a later version.
Which macOS version is installed?
Currently, the overlay on Mac OS X is a bit of a hassle. Programs you want to load with the overlay enabled have to be bootstrapped by a launcher executable. What this means is that the program has to be launched via the overlay launcher by passing the path to the program to it. Intel MAC Book Pro. John KC9KKO reported the following: 'This week I installed Outpost on my INTEL Mac Book Pro and it runs nicely. First I installed a product called Crossover MAC from the Codeweavers site, then ran the OUTPOST installation executable, and then ran OUTPOST. I configured it to access the BBS's using the TELNET.

From the Apple menu in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Big Sur, followed by its version number. If you need to know the build number as well, click the version number to see it.
Which macOS version is the latest?
These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Big Sur. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.
If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.

Network administrators can use this information to make sure that Mac computers and other Apple devices can connect to services such as the App Store and Apple's software-update servers.
Ports used by Apple products
This is a quick-reference guide showing common examples, not a comprehensive list of ports. This guide is updated periodically with information available at the time of publication.
Some software might use different ports and services, so it can be helpful to use port-watching software when deciding how to set up firewalls or similar access-control schemes.
Some services might use more than one of these ports. For example, a VPN service can use up to four different ports. When you find a product in this list, search (Command-F) in your browser for that name, then repeat your search (Command-G) to locate all occurrences of that product.
Some firewalls allow selective configuration of UDP or TCP ports with the same number, so it's important to know the type of port you're configuring. For example, NFS can use TCP 2049, UDP 2049, or both. If your firewall doesn't allow you to specify the type of port, configuring one type of port probably configures the other.
