Imac 27" mid 2010, 16Go Ram., Yosemite 10.1
I loose connection to mouse and key board very often.
Most of the times (may be every time, but I am not sure) this happends when I drag a file from one place to an other, (i.e. from desktop to a mail for example). I cannot put the icon where I want, it stays on the mouse pointer and no key nor click are effeicient.
When that happends, I can only stop the computer by doing a left click on the appel menu, chose restart with a left click and then stop with the return key, other keys do not work.
When the computer restart, sometimes but not alwys the mouse will not open the window to key in the password to start the computer.
Usually after one hard stop, it will start again.
This already hapend in december, I went to the Apple store with the computer and I was told that the problem was due to not enough memory.
I have now the max 16Go, I always have some free memory of at least 6 or 7 Go.
It was better for a while, but now it will do that very often.
Let me know if you need more infos and if you can help me out.
Thank you
iMac, OS X Yosemite (10.10.1), RAM 16 Go
