Slow start MacBookPro Retina (Mid 2012)

Hello.

Since a few weeks I've observe that the startup time of my MacBook Pro Retina (10.9.2) takes a lot of time.

Normally it tooks about 20 sec for booting and then the Mac shows the sign-on screen.

Now it takes about two minutes longer then before.

After severall other tests and checks I start my Mac in verbose mode then.

At the first moment they start quick and then they paused – here is the log text:

…

Mar 16 19:06:50 localhost kernel[0]: IOThunderboltSwitch<0xffffff8048609e00>(0x0)::listenerCallback - Thunderbolt HPD packet for route = 0x0 port = 11 unplug = 0

Mar 16 19:06:50 localhost kernel[0]: IOThunderboltSwitch<0xffffff8048609e00>(0x0)::listenerCallback - Thunderbolt HPD packet for route = 0x0 port = 12 unplug = 0

Mar 16 19:06:50 localhost kernel[0]: AppleUSBMultitouchDriver::checkStatus - received Status Packet, Payload 2: device was reinitialized

Mar 16 19:06:50 localhost kernel[0]: pci pause: SDXC

At this point the boot processe stopps for abput tweo minutes – then the boot process continues normally and fast as expected.

Here are the next lines of the log text:

Mar 16 19:03:37 localhost com.apple.launchd[1]: *** launchd[1] has started up. ***

Mar 16 19:06:50 localhost configd[18]: network changed.

…

What me makes wonder is, that the next line has an time stamp which is abput 2,5 minutes earlier then the entry before the boot process paused!?!

That is really strange I think.

At the moment I'm not shure, if the command line "pci pause: SDXC" or the next command line "… launchd[1] …" is the reason for the break during the booting process…

Does anybody know about this behavior and can help me solving this problem?

Thanks a lot.

Kind regards,

Juland.
