[GENIUS] the Acceleration of the cursor in OS X, the problems with Wi-Fi and automatic opening Windows on Mac

Reliability, coupled with the simplicity, is the cornerstone that Apple founder Steve jobs laid into the Foundation of the “Apple” of the Corporation. However, whatever the technique, its operation process will inevitably arise various questions. Sometimes they are caused by malfunctioning software issues, at least ā€” the fault of the electronics, but, fortunately, there is a category of problems that can be solved without going to repair or buy a new device. These are the questions most often asked in the comments, and in the Genius category we will try to help.

The first question is about difficulties in the operating system Mac ā€” OS X (as for the first item, you can recommend a good protective glass, this method was used by the author).

In order to solve this problem, you can seek the help of the chief ally advanced users ā€” “the Terminal”. Open the program (by default it is located in the Utilities folder) and enter the following command:

defaults read .GlobalPreferences com.apple.mouse.scaling -1

The range of valid values here range from 0 to 3 that corresponds to the speed settings move the cursor in the “Mouse” menu in “System settings”. However, the value can make negative (-1), and after the restart the speed of movement will be constant. If we are talking about the trackpad, the command looks like this:

defaults read .GlobalPreferences com.apple.trackpad.scaling -1

By the way, to return the settings to the original settings is easy: to do this change the speed of movement of the relevant paragraphs of the “System settings” (“Mouse” and “Trackpad”).

The next point is unstable wireless WLAN connection on the Mac.

In case of such problems you can follow a few simple steps. To start turning off Wi-Fi in the status bar of OS X and go to system folder, using the shortcut [cmd]+[shift]+[G]:


Find here the following files

Now delete the files previously created a backup copy in another folder, and perform a computer restart. It is also recommended to find an optimal channel of the wireless connection and use the 5 GHz band.

The last question relates to the automatic opening of Windows applications in OS X.

Once with something similar encountered, and your humble servant. This behavior can be related to the settings, located under “Basic” menu “System settings” and appeared in OS X 10.7 (Lion). To prevent opening the last window, you should tick the option “Close Windows when quitting program”. By the way, if you want to disable “Recent items” in the drop-down menu, select a value of “No”.

As you can see, some problems are easy to solve on their own. If you encounter any of them, feel free to ask for advice in the comments to this entry, and how to make the gadgets easier and more convenient, you can find in the publications of the author with notes [OS X] [iOS] and [Watch]. Of course, in the discussion encouraged mutual assistance and the exchange of ideas, which are then taken into account in the preparation of the editions. I’ll see you next time!
