Echo - I’ve worked with computers (against my burning desires) for years (I don’t nerd out on them). The most likely reasons are (1) A slow internet or an update on your service that needs to be done. Try resetting your internet (turn it OFF) for 5-10 minutes (2) Your computer is old (5-7 or more years) but because you have a Mac, this is less likely (3) Your internet speed is just too low (making it slow). Try resetting your internet, shut off your computer, and restart it all again. Sometimes it’s the most simple things…let me know. I use PCs for a reason. Dell makes a sturdy product (though i7, 1TB, 2080s run about $900).
