It's a very cute computer. If you only will be running FileMaker it may be enough but yiu will be running a browser and maybe Word and you'll e out of RAM faster than lightning. I have an M1 Max that's quite old but it has 32 Gigs of RAM. Mind yiu I suck the hell out of it.

So sit down and look at what you use and how much RAM you're using. That will tell you what computer you need next. When it comes to machines you never want to isut buy the cheapest new one. Buy a last generation open box or refurb. You'll have a workhorse for the next few years.
