this is a M1 model - It is fast, it is light, it is powerful, it wakes up in seconds..... it saves me time like crazy, no longer the annoying ball.... - it replaces my old and faithful MacBook Pro late 2013 (yes! 2013) - everything works from the beginning..... in my older Mac (which I still keep just in case) I could still run everything I needed, but it was definitely much slower - the new one is great - take the op to say KUDOS to Apple! until 10 days ago I was still using a 7 years old computer, running Big Sur and every single app I needed and the only change, has been one of speed (great change by the way) - all is compatible, I just put in a CalDigit dock and do not need to buy anything else new..... - well done!
