Is there a way to upgrade my MacBook Pro late 2011 MacBook Pro 13" Bluetooth to Bluetooth 4.0 without using a usb extension? As I only have one working USB port.
I do not see a way to do that.
Aside of software/firmware from Apple, there is the hardware issue as well.
QuickerTek makes a card that replaces the Apple WiFi/Bluetooth card. A bit pricey at $149: http://www.quickertek.com/products/Ucard.html This works in 2011-2012 13" and 15" MacBook Pros (non-retina). The version for 2011-2012 MacBook Pros (non-Retina) uses Apple's driver.
Also have versions for:
- 2010 15" MacBook Pro - uses a firmware patch
- 2009-2010 13" and 15" MacBook Pro, and 2009-2011 17" MacBook Pro - uses a firmware patch and have to disable original Bluetooth card
QuickerTek also makes cards for MacBook Airs and Retina MacBook Pros.
