So maybe this is the same for the others that have this problem, even with the Mac. It doesn't seem to matter if the window is minimized or not. The issue seems to be when a window or program is open or running in the background, the mouse cursor becomes invisible. Once the window was closed the cursor reappeared. I rebooted the computer again and left explorer open but minimized, launched the game and again the cursor was invisible. So, I closed the window and the cursor reappeared. The explorer window being open was the only difference. Yesterday I had rebooted the computer and when I started The Sims 3 my mouse cursor was visible, but when I minimized my game and searched for something, the cursor disappeared. I usually kept The Sims Exchange open or an Explorer window open and that was when my mouse cursor would be invisible. Anytime I ran the Sims 3, I had windows open in the background. However, I think I may have found the problem. I had the computer built by CyberPower and had them install Windows 7. Next, hit Enter on your keyboard to restart the computer. After rolling back to the older driver, check if the problem is resolved. The mouse keep freezing when playing games issue will be solved.

When Properties window opens, go to the Driver tab and click on Roll Back Driver button.

Then press the Tab key to shift cursor focus to the ‘OK’ button. Double-click the device to open its properties. Next, press the Down Arrow key till the drop-down menu displays the ‘Restart’ option.
