I am sure that in the past, I have been able to change the line spacing in Mac Mail. However, I can not find a way to do it now. Normally, I haven't been too concerned until I noticed that the lines in my mail compositions are SO TIGHT! Why can't I increase the spacing? Also, I have composed the message in Mac Pages with the proper formatting, then pasted in Mail and it does not retain the formatting. I've attempted to use TextEdit as well. I've then tried "copying the style" and "pasting style" which also does not work.
I have a 2010 iMac and it is still very responsive, even using the latest Photoshop, Illustrator and InDesign. I do movies and music comp as well. However, OS updates are no longer available. I am running MacOS Sierra 10.12.6 if that is relevant.
Thank you so much!!
