Over the past several Major updates to Illustrator, the Align to function's Default setting keeps getting changed. I prefer to have control over that. As all past versions of Illustrator have allowed. For me: Align to Artboard.

With the last version capable of running on HIGH SIERRA it was BROKEN AGAIN !!!!

Adobe's response is to buy a new computer.

My feeling is Adobe should FIX that last High Sierra version.

In the middle of a Pandemic/Economic uncertainty, this is not the time to screw customers.
