I upgraded to a MacBook Pro last year, so not much time to use this MacBook Air. &nbsp;<div>Hesitated for a while and eventually think it is redundant. &nbsp;So, made up my mind to sell here.&nbsp;<div><br></div><div>This MacBook Air has been connected with external keyboard and external monitor almost all the time (&gt;99% of time). &nbsp;</div><div>You can hardly find any finger print wear on the keyboard.&nbsp;</div><div><br></div><div>I use a software called AIDente Pro, which keeps the machine to use external power directly and limits the charging between 60 and 80%. &nbsp;The battery never gets overcharged or stressed. &nbsp;(if you are a Mac fan, you probably know this software, it is much better than MacOS's own battery optimizer) . &nbsp;</div><div>The battery health is 100% and only has 13 cycles.&nbsp;</div></div><div><br></div><div>Please see my pictures for the information mentioned above.&nbsp;</div><div><br></div><div>The original packaging together with cable and charger are also included.&nbsp;</div><div><br></div><div><br></div>
