Metroid Prime 2 Scanning Error

[Yeezus55]

I don't know if there is a fix for it, but I'm having trouble scanning items in Metroid Prime 2 Echoes with Dolphin 4.0. There are certain items that I need to scan in order to advance through the story. The scanner works with Dolphin 5.0 but it can get very laggy sometimes. With Dolphin 4.0 the game runs perfectly but as I said the scanner isn't working. I'm playing this on my Mac, anyone know how I could fix this so I can play on Dolphin 4.0?

We don't support anything less than 5.0
