Possible to create a blockquote in Apple Notes?
I have never seen such an option. In macOS, the built-in help (Help &gt; Notes Help) makes no mention of a block quote feature in the &quot;Write and format notes&quot; section, and a search within Notes help for &quot;quote&quot; did not return any results.
I think your best option is to increase the indentation of the text using Format &gt; Indentation &gt; Increase (⌘]).
On iOS and iPadOS, there is an option to increase indent under the format (Aa) menu.
