Q: How do I have Safari open in Full Screen in Maverick?

Go to System Preferences/General. Make sure "Close windows when quitting an application is Unchecked.

Then open Safari/Go to Full Screen and quit. The next time you open Safari it should be in full screen.

This method works but I dont want the same webpage open that I had when I closed it

Just click Command / Control / letter " f" .

This will toggle on the Full Screen Mode.

It will stay that way until you toggle it again for Off.

Of pull it down from the "View" menu in Safari.

I have seen this same answer shilled all over the discussion forums, but it isn't really a solution, it's a workaround.  It doesn't allow Safari to relaunch in Full-Screen, it allows Safari to re-open your previous full-screen window upon launch, there IS a difference.  Specifically, if you ever close your Safari window, any new windows will not be presented full screen; same if Safari every unexpectedly quits

The central issue is that there is a change in behavior here, with or without the indicated checkbox is selected, Mail and Calendar both re-launch in full screen mode, while Safari does not.

The workaround is a decent crutch of a solution, but it would be great to have an actual true fix.

Yes. Thank you this is all exactly correct.

Try quitting the app using option+command+Q

Option-Command-Q just does the same thing as the check box, its the app and keeps the window.  Having the app reopen your last window doesn't solve the problem, at best it works around it.

Does anyone have an update on this? I agree, unchecking the "Close windows when quitting an application" setting is not a fix. I want a Safari to close everything when I quite and I want it to open again in full screen when I launch it, but fresh, no old tabs.

I don't understand why this isn't fixed. All other applications (at least the ones I use) do this already: Mail, iTunes, iPhoto... why not Safari?

This sounds crazy, but just try this, can't hurt!

1.open a page.....then expand it

2. Then, minimize it (don't close it ).

3. Open another page which should open to full size!

4. Then close them both, and try to open a new page. 

Did that work for you? It worked for me on 2 different laptops having this problem. Seems to have reset them.

Simple. Tell Safari not to load anything from the previous session in its preferences. Top choice under the General tab. Change the drop down menu to "A new window", and the second to "Empty Page" (where I have Homepage).

B - You've posted this solution in two different discussion. It did not work for me. Safari was defaulting to a default small window. The solution of changing the System Preferences does reopen in full screen, but on the last page opened. I'm thinking this is one of the little glitches created by El Capitan.

This worked for me, with Safari 9.0.3 on El Capitan.  Open Safari and resize it by dragging the edges of the window.  DO NOT use the green button to maximize the app.  It should reopen exactly the size you left it.
