Mac Pro ethernet says cable unplugged with cable actually plugged in

Mac Pro ethernet says cable unplugged with cable actually plugged in

My new Mac Pro had a strange problem. When I turned on the Mac or woke it up from sleep it had no ip anymore. The only way to fix this problem was to switch the cable from ethernet 1 to ethernet 2. Sometimes I had to repeat this step, turn wireless on and off and finally I got an ip. When I restarted the router I did not have to switch the cables, then I got an ip immediately after the restart.

I searched on the internet and found several solutions:

  • Reset PRAM
  • Remove and add the ethernet connections
  • Check the cable (the cable worked for years on my MacBook Pro)
  • Try different ports on your router

None of these succeeded. I decided to contact Apple within a few days but first I searched again on the Internet. I found this page which described exactly my problem. The interesting part of this thread was about the FritzBox since I do have this router as well. The thread suggested to disable energy saving mode on the ethernet ports of the router. Which turned out to be the solution! Now my network is immediately connected after a reboot or wakeup.

Mac Pro sound defaults to internal speakers after restart or shutdown.

Mac Pro sound defaults to internal speakers after restart or shutdown.

Every time I reboot my Mac Pro the sound output resets itself to internal speakers. This is quite annoying and I had no clue how to fix it. This topic on the Apple forums shows how to fix it.

First delete the audio preference folder:

$ sudo rm -r /Library/Preferences/Audio

Recreate a new one:

$ sudo mkdir /Library/Preferences/Audio

Change the permissions:

$ sudo chown -R _coreaudiod:admin /Library/Preferences/Audio

Go back to the sound preference panel and set the audio to the one you prefer. This will recreate the settings file.

Reboot the system and see if it works.
