I've written a macro that updates several sheets and

Is there a way to turn off the screen updates until the
macros have finished?

Application.ScreenUpdating = False

Calculations can also slow down your macros. You might want to add
Application.Calculation = xlCalculationManual to the start of your macro
and Application.Calculation = xlCalculationAutomatic to the end.
