I have been waiting awhile to upgrade from MacMini to the IMac. Wish I could have done it sooner, but all Mac users know it’s not inexpensive. Having said that, it is worth waiting for and worth the money. I bought a refurbished one and there is nothing negative that stands out. Like all Macs, you plug it in and you’re pretty much ready to go. I use my Mac for everyday stuff but I also use it for making videos so need a lot of memory.  Even though this computer is several years old and refurbished, I could not be more pleased with its super fast processing and amazing 27” screen which is so incredible you feel like you could jump in! This computer came with an apple mouse which I connect thru the included keyboard. It was also very well packed.  I have all my files backed up just in case but fingers crossed this IMac continues to be my workhorse till I’m ready for another!
