Maybe something is wrong with the shader cache.
1. Make 100% sure you are on the latest development version of Dolphin.
2. Try and delete or rename the whole "Dolphin" directory in /Users/"yourusername"/Library/Application Support/ (this is to return everything back to default settings and will also delete your shader cache AND savegames so be careful if you are going for the delete option)
3. Start Dolphin
4. Don't touch anything to change graphics settings (Dolphin is set up to run at the fastest speed possible without breaking the game by default) and only change the controller buttons if you need to
5. Start the game and see if the issue is solved
Still slow? Then your MacAir is really too slow to run the game, nothing we can do about it, remember: MacAirs are created to be ultra portable and last forever on a battery... not to play games on or do any other demanding tasks (even though they do work but SLOW) also OSX drivers are notoriously slow and broken in OpenGL since they don't update OpenGL anymore (and thus you are stuck on an older version of OpenGL) and instead went over to Metal, for which a back-end doesn't exist yet in Dolphin. Recently someone took it upon himself to try and create a Metal back-end (again) but it is far from ready as of now.
Still missing coins and blocks? It might be useful to create a bug report for that in the Issue tracker (all the way down on the download page, fill in EVERYTHING that is asked)
I did everything you said and yet the coins and blocks are still missing for me.
