Hi Stefan,

Couple of things to try...

Have you done a PRAM reset, CMD+Option+p+r...

In fact, do 3 in a row, takes a bit of time.

Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Reboot.

Hardware-Übersicht:

Modellname: Mac mini

Modell-Identifizierung: Macmini6,1

Prozessortyp: Intel Core i5

Prozessorgeschwindigkeit: 2,5 GHz

Anzahl der Prozessoren: 1

Gesamtanzahl der Kerne: 2

L2-Cache (pro Kern): 256 KB

L3-Cache: 3 MB

Speicher: 4 GB

Boot-ROM-Version: MM61.0106.B00

SMC-Version (System): 2.7f0

Seriennummer (System): xxxxxx

Hardware-UUID: 599419B4-354E-5AE1-B151-B8EDB40307D4

as you can see - it should be all ok and efi is MM61.0106.B00 which is correct and can be upgraded.

but still no chnage, update applied successfully, after reboot it pops up again, and the soundcard disappeared.

Hmmm, yes it should work, just wondering, did you try it directly, or just SWUpdate?

Have we done this yet?

Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Reboot.
