Mission control desktop created on every startup

by harderanger / March 22, 2015 4:58 AM PDT

Hello!

I have noticed that for months on end now, everytime I turn on my Mac Mini, a new desktop is created (accessed via Mission Control). As you can see from the snapshots before and after a restart below - this is getting rather ridiculous - and I'm sure it can't be doing many favours for speeds too.

Btw - pretty sure it occurs on every startup - can't be 100% sure though.

Any help would be very much appreciated!

Possibly not a bug but,
by mrmacfixit Forum moderator / March 22, 2015 9:31 AM PDT

definitely something not right with this machine.
This user has, at the last count, 67 different desktops! There should only be one.

@harderanger: Create a new admin account on that mini and log into it.
Do you get the same thing happening?

I did see something like that long ago where

It was some terminal service like VNC and for each remote session there would be a desktop to serve up that instance.

I wonder if they have login items under control?

Not login items

Hi Bob,

I can't believe it can be login items issue as when I create a new user with no login items as suggested by mrmacfixit, the issue still occurs!

Then what's not stock?

My only recall of this involved remote access apps.

Did some tests...Any ideas??
by harderanger / March 23, 2015 3:29 AM PDT

Thanks for the reply!

Tried that, still does the same. I tried loads of combos of methods of logging in, and found some interesting results - any ideas please?


-Switch user (via Fast User Switching menu and main login menu) -> No issue

-Restart or shutdown (with and without reopen last windows selected) -> ISSUE! A desktop is created!

-Log out & login from main login menu or from other user's Fast User Switching menu WITH another user logged in -> No issue

-Log out & login from main login menu WITHOUT another user logged in -> ISSUE! A desktop is created!

Doh

Please note that the last two results above are inconsistent

Same happen to me
by GianlucaCane / May 23, 2015 5:47 PM PDT

Hi Harderanger, All,
same thing happen to me. New desktop is created every startup.

iMac late 2012, 16GB ram fusion drive, Yosemite, One single user configured (as admin). Formerly Maverics then upgraded to Yosemite. NO check re-open apps at startup. The only app installed: iWorks, Office 2011, Parallels, VM Fusion, teamviewer, Google Chrome.

Just getting crazy, yesterday i've installed OSX Yosemite from scratch. Formatted HD and installed Yosemite. NO Time machine restore. Every software has been downloaded again and installed. Every data or information has been copy and pasted from my external hd (mp3, pictures, documents,...).
The only app installed are: iWorks, Office 2011, Parallels, VM Fusion, teamviewer, Google Chrome.

so it' SHOULD be just clean. but..........It happen again !!!!!

ME TOO!

In reply to: just forgot

Thanks for replying GianlucaCane.

I think i forgot to mention this too...but I TOO have two monitors connected! This must be at least part of the reason for the issues. I know Apple haven't been great at supporting mutiple displays, but they improved it a lot with Mavericks, but wouldn't be surprised at all if this is an issue that has slipped through.

So, anybody, any ideas??? Wink

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
