You should be just fine..Apple offers a 1year warranty on all their products… 90 days+ free technical support and 2 weeks return policy… longer if you get AppleCare+ shortly after you buy your new M4 Mac Mini.. that extends the warranty to 3 years and covers lots more stuff( great insurance just-in-case) , well worth it… oh , and just to ask, when you get your new M4 Mac mini , are you going to be having and doing a regular backup with, say, something free, reliable, automatic and built into the MacOS… Time Machine !? ., not gonna say you won’t ever need to use it or have a backup, but you might, and you never know when a backup might come in very handy , might even “save your bacon” so to speak.. all’s you need is a USB external drive ( ssd or hard drive) roughly the same capacity as your Mac mini or bigger… and Time Machine turned on, and there you go-safety and peace of mind…
enjoy your new Mac Mini, sir
