The mac itself works well and arrived in good condition, but alot of the keys of the keyboard don't work and the mouse times out after 2 ish minutes so you have to keep clicking to get it back on which is annoying, So will probably replace these. I came from not having an Imac or macbook so the software has been a challenge to get used to, even though I have an I phone and I pad. But no fault of backmarket so still overall happy with my purchase.
