Software opens outside of my Mac's screen and I can't move it back on-screen!?

I had this issue after disconnecting a larger screen that my photshop window fit on (larger than native screen resolution at the time). I went to system preferences> displays> clicked "scaled", then selected "more space". This gave me a larger resolution on my screen opening it up enought o see the entire photoshop window. This won't work if you are at maximum already, I assume... But changing those setting may force the mac to resize you windows though to fit inside your screen.

I have this problem daily.  I work in AE, Premiere and photoshop at work.  I've disconnected my second monitor, shut down the app, restarted my computer and it still opens off screen on my laptop. The only way I can work is if I mirror my display when connected to Thunderbolt. That gives me a larger viewing space to move the window around. But that defeats the purpose of working with two monitors. And if i move the window down and go back to dual monitors it goes right back under the menu bar. 

I had the same issue... I have a second screen. I solved it by opening System Preferences > Display and changed the screen resolution for the main screen where the app is open. This way the app fit on the screen. So I was able to move it to my second screen and revert back the resolution.

It's been an issue for YEARS and I'm surprised I've stumbled upon this myself and have yet to see this on the internet yet. (or I'm not looking hard enough) Everyone told me to change the resolution but every time I change it back the screen goes partially off-screen again.

Try holding fn+cmd and clicking the window's bottom edge. Dimensions stay locked but you can freely move the window.

This literally just worked for me. However, If the header bar is locked on the top of the screen it doesn't work. BUT, if the window is floating off-screen, you can click and drag the edge while holding these command and the window will retain its shape but follow your mouse! Please let me know if this worked. I feel like I've saved lives today. I'm still shocked that I've figured this out so I thought I'd find a forum and share the good news.

Update: It only worked on a few programs. I've since noticed it hasn't worked on everything. I've been using the trick for AE.​

I think this might be related to a secondary display that's no longer online.  This should be fixed in the next update, but there's a workaround for now:

Open Mac OS System Preferences > Display and change the Resolution scaling to something else.  Audition should reset for that resolution.  Resize and/or move it to position it clearly within the next display, then close the application.  Restore your display resolution and open Audition again.

Jonnoh  wrote I think this is happening because I use 2 screens in the office but I always quite all applications and turn off my Mac before taking it out of the office. I've tried quitting and reopening the application but the same problem keeps occurring. I've tried restarting the Mac and turning it off and on again but keeps happening. I've looked into the display settings in preferences but no joy! I've tried disabling Mission Control in Hot Corners but it still opens off-screen! I've looked a lot into Audition's 'Window' and 'View' settings but nothing seems to bring it back on-screen!?

I'm not quite clear here - have you tried moving Audition back to the laptop screen before closing it, unplugging the other monitor and seeing where it opens? It should remember the last place it was operating from.

Have you tried setting the Workspace back to the Default? In the Window menu Workspace/Default.
