Just to piggy back on this /u/JagexIago , could the Hall of Memories on mac clients be looked into, when the memories change location it completely locks the client up. You're unable to visually see movement, memory locations or any interface contents that wasnt already visible on the screen when they moved.
This may well be fixed with the same update. If it's not, let myself or u/Shaunyowns know and we'll chase it up.
