Is there some way that I can make TextEdit open a new document set to "Wrap to Window" as I don't like the large gutter around the edges since it is just text document and normally not printed out?
The global preference for each new document in macOS 10.14.6: TextEdit Preferences > New Document > in the Format section, untick Wrap to page.
When that preference is ticked, to change an open document: in the TextEdit menu bar click Format > Wrap to Window.
Booted to Mountain Lion, tried TextEdit.
Did the same booted to Yosemite, then returned to my normal Mojave system.
TextEdit app showed the exact same options in preferences on all three systems.
None show the Format> Wrap to Window.
All show Format> Wrap to Page
Where, exactly, in the preferences do you see Format> Wrap to Window (?)
I'm still not sure exactly what difference in a text document you expect to see.
Ah, OK....
The settings in TextEdit for both Mountain Lion, and Mojave are virtually identical.
So, it's probably pointless to upgrade your OS X system, when there is no distinctive change in the look of TextEdit
You can get the (plain) window that you want as a default for a new doc by unchecking that Format< Wrap to Page box.
And, as rshrugged pointed out above, you can toggle in and out of that plain-view page by clicking on "Wrap to Page (or Window)" under the Format menu in Textedit.
Or even easier, if your doc is showing the "gutters" that you don't want, simply press Shift-Command-W, and the wrap mode will toggle instantly. (You do need to have an active doc (with TextEdit menus showing in the top menu) for that quick toggle to work, of course)
So, those lines that you call "gutters" are just showing you the page size, with the relative placement of the margins.Select “Wrap to page” to wrap text within the document’s page margins.
Otherwise, text wraps to the document’s window size.
The TextEdit user guide (available under the Help menu) has something to say about that:
So, those lines that you call "gutters" are just showing you the page size, with the relative placement of the margins.
Alternatively, wrap to window just shows you the window, no indication of margins, just text (and what you want)
What I just did, and it worked:
Open TextEdit (the version I have is 1.6)
Open preferences --> New Document
Wrap to page --> UNchecked
Close preferences
This option MIGHT NOT BE THERE on an older version.
For what it's worth, my saved TextEdit documents open at whatever the window size was when it was last Saved. I just opened a bunch of documents, and each opened with a different window size. If I then adjust the window size and Save, when opened the next time it opens to the new (adjusted) size. If I adjust the window size but do not Save before closing, it next re-opens at the original size.
If I understand correctly, all your Saved TextEdit documents are opening with a single window size, regardless of what you saved?
FWIW, I get the same behavior with Plain Text documents in macOS 10.14.6/TextEdit 1.14 (341).
Plain Text -- change window size > save > close. When reopened, window size change is not maintained; document uses preference settings.
RTF -- change window size > save > close. When reopened, window size change is maintained.
Plain Text workaround to maintain window size -- before saving/closing document for which you've changed the window size: TextEdit menu bar > Format > Make Rich Text. Save/close. After reopening: Format > Make Plain Text.
This is the only way I've found that works for me. I've tried changing encoding, etc. Doesn't mean there isn't another way. The only reasoning I could come up with is Plain Text's lack of formatting, including the ruler functions. Is it tied in? Just a guess.
