No font samples on Acrobat on Mac Os
The font list on Mac Os Acrobat is in the standard font- see screenshot (usually each font name is shown in its style so you understand what it looks like more or less).
On Acrobat on Mac Os in order to see what font looks like you need to apply it to the text in the document - so you literally need to apply 100 fonts to see what they are when looking for the right one.
In short - there is no preview samples of fonts on the list like there is on Acrobat on Windows. I had to cancel my subscription on Mac because of that and i am sure i am not alone.
I spoke to your customer support and they confirmed that it is so and it's not a bug. If possible - let me know when it's fixed so i could subscribe again.
