The application I/we use to get the data from Itunes and others mediaplayer (spotify, winamp,...) has hotkeys so you can change songs from ingame.
Np, thank you for being understanding.
Are you sure the G502 Proteus Spectrum doesn't work on macOSX? Here's an Amazon referral to the mouse in question, and it says it supports macOS 10.10 or later.
Here is a clip of me doing airblades in:

Any mouse will be fine, I've used this $20 mouse for literally 5 years now.
Ping is kind of a big issue, consult this post and see if you can bring it down.
As far as using your e effectively, you need to 1) plan in advance, and 2)Know exactly where you will end up (for 1 dash it doesnt really matter, but when you are trying to chain dashes, it becomes a big deal very quickly).
That being said using dash generally boils down to a few things:
1: Using e as a pseudo auto reset (This is actually hugely important for trading and farming, use it as much as you can)
2:Going in and immediately back out to bait a move
3:Going in for a trade while you have a window of opportunity*, and leaving when it ends
For all of these you shouldnt have to use more than maybe 3 dashes, and you should be able to plan it in advance, and by plan it, I mean figure out which minions you will use, and whether they'll be where you need them to be when you need them to be there. You don't want to waste dashes because that shoves the lane, and yasuo is very vulnerable to ganks.
*In analyzing if you have a window of opportunity consider the following: Relative power of and your opponent in items(knowing matchup powerspikes is critical here), passive shield status, 3rd q status, fervor stacks status, e stack status, ability cds for you and your opponent, and summoner spell cds.
