It is worth keeping an eye on the Mac malware situation rather than pretending it does not exist, or is someone else’s problem.
As the Mac user-base has grown so has its popularity as a rewarding fishing spot for hackers. Linux has seen the same growth in interest and abuse.
The recent MalwareBytes report is unfortunately being misrepresented by many who have not read past the misleading headlines to the bottom of the articles.

And just for laughs
The point to observe isn’t that there is a claim that the Mac world has more malware than Windows, but that the acceleration rate is now faster due to a simple numbers game.
If you start with 1 malware then another turns up, you just increased by another 100%, but that does not mean you have a lot of malware.
The Mac world is still a whole lot safer, but it now shares the same hardware and sub-layers as the rest of the x86 world. We run browsers that are now an OS in a window, so have become a playground for malware that works on any OS.
The networks and hardware you use is now the common target for many hackers, which again is OS agnostic.
Every OS can send and receive files from any OS, so any OS can be a “super-spreader” of contagion as long as the host is not actually the target.
Personally I feel it is everyone’s responsibility, so everyone’s duty to keep each other from harm whenever possible.
No matter what OS though you may not be at risk, but if you handle lots of files from or for other people for any reason, you may want to consider a standalone AV scanner by one of the few AV vendors that don’t keep popping up in the news for all the wrong reasons.
If all the files you receive are via a browser then you can even just make use of a remote scanning service such as VirusTotal or OPSWAT with a browser extension.
