Hello.  My 16" MacBook Pro will be arriving soon.  In preparation, I'd like to get some advice on covering up ports that I will not be using, primarly to avoid collection of dust.  I could use tape to block the unneeded ports.  But for want of a better solution, is there such a thing as 'empty' plug or 'dud' plug that fits into a given port but does nothing?  In particular, I know I will not be using SD slot.  So is there such a thing as 'dud' SD card that I can leave in there?
If there are better solutions, I'd like to know. Thank you in advance.
