Then why does MacOS handle window positioning like this:
1. With no external monitor connected, open some Finder windows and position them in the middle of the screen.
2. Open Finder View Options and move window to top left corner of the screen. Then close.
3. In Finder, open Go > Connect To Server and move window to middle of the screen. Then close.
4. Open applications such as Photos, News, Stocks and put the windows in the middle of the screen.
5. In applications such as Keynote and Omnigraffle, create new documents and put them in the middle of the screen to work on them.
6. Save the documents.
7. In VMWare Fusion, start up a virtual machine and move the virtual machine window to middle of the screen. Then quit VMWare.
8. Close all documents and windows.
9. Connect the external monitor (30 inch, 2560x1600 resolution) which is configured to be the main monitor. Open previous Finder windows, applications and documents. Everything that was previously in the middle of the screen is now thrown into the bottom left corner of the large monitor.
10. Applications such as DVD Player keep opening in the bottom left corner of the screen no matter how many times I move the window.
11. If I open a shared folder on a Mac with a smaller monitor and then open it on a different Mac with a larger monitor, the folder appears in the bottom left corner of the larger monitor.
Same thing happens whether I connect the 30 inch monitor while all applications are open, or if I save and quit everything before connecting the monitor.
I have seen this irritating behavior as far back as MacOS Yosemite and it continues to this day (MacOS Mojave 10.14.2). Every time I use my laptop offsite and then come back and reconnect my 30 inch monitor, I am afraid to open anything for fear that all the windows will be thrown into the bottom left corner of the screen. I have never seen an operating system handle window positioning as STUPIDLY as MacOS.
Since I doubt that all the developers of these applications secretly conspired to purposely put all their windows in the bottom left corner of the screen, I must conclude that something in MacOS is causing this to happen. Instead of saying "just move the windows yourself", people should be telling Apple to:
Fix the stupid, retarded window positioning algorithms in MacOS
Stop assuming that everyone uses a 12 inch MacBook as their only monitor
Stop assuming that everyone wants to spend their time looking in the bottom left corner of the screen.
