Having done this for a very long time, I can tell you that you should definitely use a dedicated genealogy program, or an online alternative. Sure there are charting apps that can make a tree, but once you need to make a change, it's a pain in the neck. With a dedicated program, you just make the change and spit out a new chart.
Reunion (
https://leisterpro.com/) is great, although expensive. There are many options, such as MacFamilyTree (
https://www.syniumsoftware.com/macfamilytree), Family Tree Maker (
https://www.mackiev.com/ftm/), Heredis (
https://www.heredis.com/en/), etc. RootsMagic is supposed to fully support the Mac in version 8, but it's been delayed. Maybe later this year. RootsMagic (
https://www.rootsmagic.com/) has a free version and a paid upgrade. For completely free you can always try out GRAMPS (
https://gramps-project.org/) which is an open-source genealogy program. If you're going to invest in a program, also look at which ones offer companion apps on the phone. If you use an iPhone, being able to enter data on the phone and then sync it to your Mac is really helpful.
Alternatively there are online sites like ancestry.com and myheritage.com which offer some free usage for building trees on the web, and they also have charting options.
