ipad 5th generation iOS compatibility

An iPad 5 or original iPad Pro isn't capable of 17 or above; they require an A10 or better CPU. Nobody on these boards can say if Apple's going to patch 16 again.

If you get it or any other secondhand iPad capable of 7 or higher, check that the unit doesn't have an activation lock before giving the seller your money.

It won't be able to run 18. If you're looking to get a few years out of it, you should buy the most recent model you can afford considering the criterion above.
