Been staking about 6k coins for over a week on my mac wallet but haven't received anything, the wallet is online and the expected time until reward floats between 2 and 3 days.
could i be doing something wrong?
The network staking weight is very high.
Huge wallets A lot of people are staking, there is not much chances to stake with 6k currently. Those estimations are rarely correct. It could take another week or two to stake.
