Hello everyone,
I can't seem to use several applications that open; the dropdown menu at the top is accessible but nothing shows up. This happens to me on Skype, Zoom, Molotov, BluOS.
I have a MacBook (15-inch, mid-2010) and my OS is 10.13.6. I have 8GB of RAM and my hard drive is less than 30% full.
Do you have any ideas? Thanks

Hello
By any chance, have you recently connected an external display to this Mac?
As a result, it may have memorized sending the displays to that screen which is not there, and thus you see nothing.
If so, I suggest resetting the System Management Controller (SMC). While PRAM still exists on Intel Macs, most critical functions are now managed at the SMC level, which handles the following according to Apple:
- The response to pressing the power button
- The response to opening and closing the lid of a Mac laptop
- Battery management
- Thermal management
- Sudden motion sensor
- Ambient light sensor
- Keyboard backlighting
- Status indicator management
- Battery status indicators
- Switching to an external video source instead of an internal one.
If any issues are encountered with any of these functions, resetting the SMC may resolve them.
Note: This operation poses no risk.
There are three methods to reset it depending on the Mac model:
- On a desktop Mac, you need to shut it down, unplug the power cord, wait at least 15 seconds, press the power button for at least 5 seconds. Then, plug the power cord back in, wait at least 5 seconds, and start the Mac
- On a removable battery Mac laptop, you need to shut it down, disconnect the MagSafe adapter, remove the battery, press the power button for 5 seconds, then put the battery back, reconnect the MagSafe adapter, and start the Mac.
- On a non-removable battery Mac laptop, you need to shut it down, disconnect the MagSafe adapter, then simultaneously press the 3 left-side keys (Shift, Ctrl, Alt ( ⌥ )) AND the power button. Hold these 3 keys and the power button for at least 10 seconds, then release them all at the same time. You can then start the Mac.
