Forms Control checkbox and code to unlock a cell

I would like to use a Form Control checkbox to change the protection and fill color of a cell. The TRUE condition should unlock the cell and change the color to a light yellow, the FALSE condition changes things back to locked and no-fill state. I've tried a few things but mostly found that the solutions are designed for ActiveX controls and not for a Forms Control checkbox, which I need to compatibility with Apple versions of Excel.

Any assistance with proper code would be greatly appreciated.

Put your checkbox in your sheet, assign it to the macro "CheckboxName", then format the checkbox to link to cell A1 (for example).
Then the code below will assign the checkbox to cell A2:
