Three Things to Try:
A. Verify the Connection:
See if the speaker is even seen:
- Hold Down: the Option key
- Click: the Apple menu
- Select:: About this Mac...
- Click: System Report... button
- Select: Bluetooth (on the left of screen)
- Look For: this Speaker
B. Try Reseting the Core Audio:
Type the following command in Terminal:
sudo killall coreaudiod
C. Perform a SMC and NVRAM Reset:
Sometimes changes are made to the system(i.e. updates) and then settings (i.e. for Power) become manipulated, technically. So, reset both the SMC and NVRAM on your Mac.
