No flaming here, but your first mistake was trying Ububtu - it's not the best in terms of hardware compatibility, and they (Canonical) often make controversial software/development decisions, which makes it one of the most hated distributions in the Linux community.

Your second mistake was trying it on a Mac. Now don't get me wrong, many people do run Linux on a Mac, but it's not quite plug-and-play (compared to PC), and not everything may work as intended. Since you're new to Linux, I wouldn't recommend your first experience of it to be on a Mac. And to be clear, this isn't Linux's fault - since Apple (or whichever chipset maker) doesn't provide Linux with any official drivers/code, the devs have to figure stuff out themselves by reverse-engineering stuff, and as expected not everything may work.

If you've only got Macs around and you don't have the patience to troubleshoot Linux issues / read manuals etc, then the easiest way to try it out is in a virtual machine like Parallels or VirtualBox. The performance might not be the best, but at least everything should work out-of-the-box. As for the distro, since you're a Mac user, you'd probably feel more at home with elementary OS. Other options you could try include Pop!_OS, and Zorin (the Pro edition even has a macOS-like layout).

Once you've tried Linux in a VM and decide you'd like to use it full-time, the best way to experience it is on native Linux-first hardware - basically PCs which come with Linux out-of-the-box, such as those made by System76, Slimbook, Star Labs, Tuxedo etc.
