Hi all, I eventually got an acceptable system (10.11) in a I5-4310U E5540 and HD-4400 graphics. I also changed the intel wifi card with a Broadcom. For sound I use VoodooHDA. I need to correct any problems in the system: 1) Do not work the battery status 2) Speakes sound, but I do not get sound through headphones output (perhaps requires Voodoo settings in the System Preferences panel) 3) Problems with iMessages to validate AppleID Any idea that can guide me? Thanks to all
