I had some weird problems with Mint which were easily solved in Ubuntu. For some strange reason, one time when I plugged my early 2008 white MacBook4,1 with Mint into my Airport Extreme via Ethernet, the entire home network went down. Unplugged it and the network was fine. Plugged it back in and he network went down again. I don't know if the settings somehow got corrupted or something and perhaps it was just a freak one-time thing, but I took that as a bad sign. Plus, the Broadcom WiFi drivers were not automatically installed so I had no network support.
In Ubuntu, while the proprietary Broadcom WiFi drivers were not automatically installed, they were available as an optional install because wired Ethernet worked fine. Of course if I couldn’t connect to the internet via Ethernet in Mint, I couldn’t attempt to install any WiFi drivers in Mint either.
Also, in Mint after wake or some period of non-use, the trackpad pointer would not move until after a several second lag. It was annoying, as if when you wake the computer the OS is only partially awake until a few seconds later. This was not a problem in Ubuntu. Once Ubuntu was awake, it was fully awake.
The other I noticed when I was troubleshooting the network issues in Mint, was that a lot of the solutions posted were not specifically for Mint. They were for Ubuntu, with references to Ubuntu’s GUI.
And finally, Ubuntu’s releases come out earlier, since Mint is based off Ubuntu (which is in turn based off Debian). There is an 18.04 LTS release of Ubuntu coming in a few days. The corresponding Mint release probably won’t be out until a month or two from now.
So, as a Linux n00b who encountered some issues with Mint on my specific machine, Ubuntu seems more suited for me.
The main issue I have with Ubuntu though, which is also an issue with Mint, is the half-assed right click support on Macs. I don’t use tap-to-click, and there doesn’t seem to be an easy way to activate something like OPTION-click, which is the way it works in Chrome OS (which effectively is another Linux distro). Chrome OS has its own issues though. For example, while WiFi worked out of the box, the drivers aren’t very good with slow speeds through an AirPort Extreme. Furthermore, Netflix on Ubuntu is smooth and stable. On Chrome it is flaky. And as everyone knows, Chrome is by design limited in its flexibility.
