If you're using a high-end bluetooth headset on your Macbook Pro it's likely your mac is using an audio codec which favors battery efficiency over high quality. This results in a drastic degradation of sound, the SBC codec is the likely culprit, read more about it here.

Find out what codec you're using

1. Play a song on your headphones
2. Option (⌥) click the Bluetooth button at the top of your screen
3. If you're using AAC or aptX, you can stop here—those are the highest quality codecs.

Change your codec to AAC or aptX

Lower precedence means a stronger binding; ie. this list is sorted from strongest to weakest binding, and in the case of equal precedence between two operators, the associativity decides the binding.

3	NEG	-e	none	Numeric negation.
4	HAS_ATTR	e ? attrpath	none	Test whether set e contains the attribute denoted by attrpath; return true or false.

Setting up your Virtual Machine

We'll be creating a new Virtual Machine on Microsoft's cloud platform, Azure. The VM will have a beefy GPU just like a home computer so it can be used for playing games.

1. Go to [the Azure portal][azure] and sign up or log in.
2. If you are on a Free account, first go to Subscriptions and upgrade it to a Pay-as-you-go plan. Don't worry, you will get to keep any free credits you have. Azure's interface is a bit slow so this will take a minute.

⚠️ Make sure to not include any support plan because they will charge you monthly!
