Dock, expose and or mouse acting weird

1 post in this topic

Recommended Posts



two days ago i left my computer on (sleep mode not enabled cause it wont recover :( ).

when i returned i saw the screensaver and got it back to work normally but quickly realized two things.

expose did not work. dock did not show up (i have it hidden). and i could not mark and then drag and drop items in the finder....

even more weird and the desktop drag and drop seemed to work. furthermore when i drag something over a folder, the folder usally pops up and shows it contents.

this does not work anymore.


i started in safe mode and ran disk utility to repair permissions.

i rebooted.


all of a sudden yesterday i was able to mark and then drag and drop items again. although the not poping up folder issue persists.

and occasionally expose work here and then.

i have the middle mouse button (wheel) configured in expose as show desktop which works fine. just the active corners dont work.

i just the middle mouse button to show the dock. when i press it and move the mouse over the bottom edge of the screen the dock appears.


some ideas not having to reinstall my system would be great.


btw ideneb 10.5.7



thanks in advance




nobody any clue?

      acabo de instalar linux mint 18 en una particion parte en un cuarto disco duro.
      Tengo windows 19 en un disco, sierra y una particion de resccate de sierra en otro, un disco dedicado a datos y documentos y el cuarto esta dividido en dos la primera particion para juegos y la segunda instale linux.
      clover me detecta la particion de linux sin problemas paero cuando ingreso a ella atravez de clover el teclado y el raton no responder, como si estuvieran desconectados.
      prove arracar directamente desde el disco duro donde el grub2 en vez del clover y detecta el teclado y el raton, asi que la instalacion de linux esta bien.
      tambien trate desde el clover configurator añadir un par de entradas personalizadas en el GUI por medio de legacy (esta en mbr la instalacion de linux) pero no aparacen dichas entradas personalizadas
      dejo la imagen de el clover configurator

      y tambien mi config.plist
      para saber que estoy haciendo mal

      Hi! I have problems with my mouse and keyboard on hackintosh.
      My mouse, Logitech G300s after installing Logitech Gaming Software slow down where cursor is near to something "clickable" (like exit buttons, etc.), when it is on this buttons, it's freeze on about 2s and it doesn't react on any mouse's move. I heard many users have this problem, but I didn't find solution. I don't want to uninstall LGS, because one button is changing mouse's DPI when I press it and with LGS I can disable it.
      My keyboard, Corsair k70 RGB can't be noticed in CKB. Just CKB doesn't see it. I tried to plug keyboard to USB 2.0 and 3.0, changing work modes (from 1000MHz/1ms to 500MHz/2s and slower), plugging after system's boot and nothing works and after install CKB media keys has stopped working.

      My specs:
      MOBO: Gigabyte P85-D3
      CPU: i5-4670
      GPU: GTX 750 Ti
      RAM: 8GB DDR3

      OS: macOS Sierra 10.12.6

      Fiz a instalação do Yosemite em um Samsung RF 511 SD3 BR. O notebook parece uma chapa de fritar ovos de tão quente que ele fica, esse problema de aquecimento ocorre no Windows tb. Ele tem uma placa gráfica Nvidia GT540 M e mais a Intel HD 3000, a Intel está funcionando perfeitamente e como sempre li que a Nvidia não funciona eu queria desativa-la para tentar deixar o notebook menos quente. Como posso fazer isso? Na config.plist já está desativada mas mesmo assim ela aparece na parte de gráficos, tem algum patch de DSDT para desativar ?
      Audio ALC 269 (AppleALC)
      Atalho para Brilho e Volume
      WiFi+Bluetooh ( troquei por uma AR5B195)

      Nvidia GT 540M
      Audio HDMI

      OK, i managed to install the OSX almost perfectly, my last problem that i couldn't fix is that every time i start my pc the mouse is not working.
      re-plugging the usb seems to make it work but still every time the pc goes to sleep or if i reboot, i need to connect the mouse right after it boots up.
      Anyone knows a solution?
