[Grafikfehler] iMac Intel 24" - Ende 2008 (EMC 2134)

[Crabalocker]

Moin Moin, liebes Apfeltalk-Forum!

Ich befasse mich gerade mit dem iMac meiner Freundin, der seit einiger Zeit mit leichten bis mittelschweren Grafikfehlern für eine gewisse Wut sorgt.
Mal sind es kleinere Fensterreste, die nach dem Minimieren nicht verschwinden wollen - mal waren es Pixelkriselungen im Bild. Heute erfolgte jedoch der bis dato mit Abstand schwerwiegendste Aussetzer:

Da ich eigentlich ein Windows- User bin, arbeite ich mich momentan Stück für Stück in die Materie ein.

Was wir bisher unternommen haben:

- SMC-Reset
- Festplattenanalyse und Ausbesserung von zwei gefundenen Fehlern mittels Festplattendienstprogramm
- Erneutes Aufsetzen der Snow Leopard 10.6.8 Umgebung (Keine Neuinstallation von Null, also vermutlich eher Quatsch)
- Gerät aufgeschraubt und anteilig gereinigt (Habe mich nach dem Abschrauben von Case und Scheibe nicht unter den Screen vorarbeiten können, da nur der größere Schrauber vorhanden war)

...bisher wie es scheint leider ohne Verbesserung.

Gestolpert bin ich über die immer wieder scheiternde Initialisierung des en1 Interfaces. Die häufige Verwendung des Ausdrucks "WPA" lässt mich darauf schließen, dass es sich hierbei um das WLAN-Interface handeln muss. Kann dieser Fehler auch für Grafikstörungen verantwortlich sein?

Häufiger erscheint in dem Zusammenhang auch folgende Meldung:

cn.com.zte.Wpa.plist[20290]    WirelessAttach: IOServiceOpen error: e00002c7

Google spuckt bei dem Error-Code häufig Forenthreads mit Skype-Problemen aus. Dieses Programm ist auf dem iMac ebenfalls installiert, allerdings war es zu keiner Zeit aktiv.

Noch eine Meldung:

cn.com.zte.Wpa.plist[20296]    Initializing interface 'en1' conf '/etc/wpa_supplicant.conf' driver 'osx' ctrl_interface 'N/A' bridge 'N/A'

Wenn in einer Windows-Umgebung N/A Bridge - Fehlermeldungen kommen, bedeutet das selten Gutes. Kann ich diese Fehlermeldung zum WLAN-Interface zählen oder steckt da eventuell "noch" mehr dahinter?

Du kannst noch den Hardwaretest durchlaufen lassen (beim Starten "D" gedrückt halten) und dir das Programm "Etre Check" installieren, einmal durchlaufen lassen und das Ergebnis hier posten.

 

[Crabalocker]

So, nach intensiver Suche der Installations-CD ist diese nun wissentlich verpackt auf einem Dachboden. Da komme ich in den nächsten Tagen nur leider nicht ran. Mist, der Hardwaretest fällt damit momentan aus. EtreCheck habe ich durchlaufen lassen und in den Startpost eingefügt. Soeben ist abermals ein Grafikfehler aufgetaucht - also wieder mal neugestartet. Die Konsole zeigt wieder die gleichen Muster auf, allerdings ist eine neue Zeile dazugekommen:

Initializer-based scripting additions have been deprecated and are not supported in 64-bit processes. "/Library/ScriptingAdditions/LCC Scroll Enhancer Loader.osax" not loaded.

//Edit: Logitech Control Center, so so. Das Biest habe ich mal vorsorglich entfernt. Daran sollte es aber wohl nicht gelegen haben.

 

[doc_holleday]

Keine Ahnung, ob das die Ursache ist, aber Avast ist böse:
http://www.apfeltalk.de/community/threads/warnung-vor-cleanup-tools-antvirenprogrammen-co.435167/

Gemäß Herstelleranleitung deinstallieren.

 

[Crabalocker]

Gut, dann weg damit. Danke! Weitere Anregungen? :>

 

[doc_holleday]

Ich würde mal alles, was EtreCheck unter "Start..." Und "...Launch..." listet prüfen, ob du es noch brauchst.

Wenn nein, gemäß Herstelleranleitung deinstallieren.

Wenn ja, prüfen, ob es mit deinem OS X kompatibel ist und ggf. aktualisieren. Gibt es keine kompatible Version, einen alternativen Weg suchen.

 

[Crabalocker]

Guter Hinweis, danke!
Die drei Viecher gehörten zum Beispiel alle zu einem ollen Surf-Stick, der vor Urzeiten mal Verwendung fand:

Launch Daemons:
[System] com.zte.Wpa.plist
Launch Agents:
[System] cn.com.zte.usbswapper.plist
User Launch Agents:
[not loaded] Huawei Updater

Somit wäre der Grund für den Spam in der Konsole erfolgreich eliminiert. Ich glaube nicht so ganz daran, dass sich an den Grafikfehlern damit irgendetwas ändern wird, aber ich warte einfach mal ab. Sofern jemand noch weitere Ideen hat, wie ich diesem Fehler auf die Schliche kommen kann, bin ich für jeden Hinweis dankbar.

 

[doc_holleday]

Ja, stimmt schon. Es ist fraglich, dass diese Aufräumarbeiten das Grafikproblem lösen können. Die Vermutung, dass hier ein Hardware-Problem vorliegt, liegt da schon näher.

Um trotzdem die Software (weiter) auszuschliessen, kannst du mal noch zu Testzwecken:
1) Einen frischen User anlegen, für diesen die automatische Anmeldung aktivieren und direkt in diesen hinein booten.
2) Kontrollieren, ob wirklich alle Updates für das Gerät installiert sind (inkl. EFI, Firmware und was es sonst noch so gegeben haben möge),
3) Das 10.6.8er Combo-Update noch mal drüber bügeln und/oder
4) Wenn du die Snow Leopard DVD zur Hand haben solltest (scheint ja der Fall zu sein, da du ja das System schon mal drüber installiert hast) diese benutzen, um ein komplett frisches System auf einer externen Festplatte anzulegen.
5) Wie 4 nur mit Mavericks, das es kostenlos im AppStore gibt
6) Upgrade auf Mavericks, inkl. Recovery Partition, etc., bringt eventuell auch noch die Option mit sich, dessen Hardware-Test zu nutzen, da bin ich mir aber unsicher, ob das funktioniert oder ob der AHT immer mit der dem Gerät beigelegten DVD erfolgen muss.

Funktioniert die Kiste mit Variante 1 oder 4-6 so wie sie soll, würde der Fehler tatsächlich durch die Software verursacht und ließe sich selbst beheben. Aber wie gesagt, so recht glaube ich nicht daran.

Daher Option 7: Termin im Apple-Store machen und von denen checken lassen.

Ganz wichtig, da man es nicht aus dem EtreCheck-Auszug ablesen kann: für Backups der Daten sorgen, wenn nicht schon erfolgt! Einfachste (und gute) Variante: externe Festplatte dran und TimeMachine den Rest machen lassen.

 

[Crabalocker]

Da bin ich wieder!
Ich habe deine Schritte 1-5 befolgt und bin bis jetzt ziemlich erfolgreich mit Mavericks gefahren. Herzlichen Dank für die Tipps. Den Hardwaretest zu starten, war mir leider nicht möglich. Allerdings hatte ich gerade erstmals wieder Grafikfehler und nun sind auch aussagekräftige Zeilen in der Konsole aufgetaucht:

18.04.14 13:07:16,000 kernel[0]: NVDA(OpenGL): Channel exception! exception type = 0xd = Graphics Engine Error (GR Error 5)
18.04.14 13:07:16,000 kernel[0]: IOVendorGLContext::ReportGPURestart
18.04.14 13:07:36,000 kernel[0]: NVDA(OpenGL): Channel timeout!

Ich hatte schon fast die Hoffnung, dass alle getätigten Fixes zum Erfolg geführt hätten - Schade! Ideen?

Liebe Grüße
Tobi

[Applicator]

Ich habe so die böse Vermutung, dass du dich nach einer Ersatzgraka umsehen solltest.
Wenn die Häufigkeit und Schwere solcher Grafikfehler konstant zunimmt und sich nach Reinstall und Resets keine Besserung einstellt, dann liegt es eigentlich immer an einer kaputten Karte.

Ich rate mal so ins blaue hinein, dass die Grafikfehler bei kaltem Gerät länger auf sich warten lassen als bei einem warmen?

 

[rootie]

Ich sag mal zu 100% ausschließen oder bestätigen, dass es ein Hardwarefehler ist, geht nur mit einer kompletten Neuinstallation (wenn möglich natürlich auch mit Mavericks). Ich habe mir dazu das Betriebssystem aus dem AppStore geladen und auf einen USB-Stick kopiert. Dann mit diesem Stick booten, die komplette Platte platt machen (inkl. Partitionen) und dann installieren. Das System dann so weit wie möglich ohne 3rd Party-Software betreiben.

Wenn dann der Fehler immer noch auftritt, ist es ganz klar ein Hardwarefehler. Wenn nicht, dann sukzessive Deine Software einzeln (!) installieren und zwischen den Installationen immer ein paar Tage das System nutzen. Ich weiß, ist langwierig, aber die einzige Möglichkeit, etwas Verlässliches rauszufinden.

Ach ja: Selbstverständlich vorher ein TimeMachine - Backup anlegen! Ich will nicht für Datenverlust verantwortlich sein
