Mac screen capture to gif

Capture the Screen Recording:

Press Command + Shift + 5 to open the screenshot and screen recording tool. In the toolbar that appears, click on “Record Entire Screen” or “Record Selected Portion” depending on what you want to capture.

Record your screen:

If you chose “Record Entire Screen,” click anywhere on your screen to start the recording. If you chose “Record Selected Portion,” drag to select the area you want to record and then click the “Record” button.

Stop the recording:
