I've been having sporadic issues where my Macbook Pro Retina hangs at startup. I started up in verbose mode and it always hangs at this message.

AppleUSBMultitouchDriver::checkStatus - received Status Packet, Payload 2: device was reinitialized

After several minutes it continues with these two message.

IO80211Controller::dataLinkLayerAttachComplete():  adding AppleEFINVRAM notification
IO80211Interface::efiNVRAMPublished():  

What do those messages mean?

AppleUSBMultitouchDriver

is your touchpad, it has some problems but eventually it does it, however, I would recommend the Internet recovery (cmd-opt-r) to reinstall the driver.

The

IO80211Controller

is your Network interface 802.11 making a note.

  • Do you think it's getting stuck at AppleUSBMultitouchDriver or IO80211Controller? – Berry Blue Mar 30 '14 at 7:07
