Aanvankelijk klapte m'n wifi-verbinding er steeds uit.
Daarna vindt m'n MacBook Pro (begin 2011 - High Sierra) de hardware niet meer (kruisje)

Vervolgens een toetsenprobleem (89 uio jkl m.) Reageren niet. Ook niet op extern toetsenbord)
Alles geprobeerd. Toetsen doen het in Single User Mode en in toetsenbordweergave (klein toetsenbordje op scherm) en in terminal wel.

Geprobeerd:
Apps bij opstarten uit.
Verschillende soorten herstarts (veilige Modus, Update Sierra > High Sierra, combo-update, PRAM/NVRAM), Apple hardwaretest etc).

Wat nu? Ik wil geen gegevens kwijtraken...

Dank alvast!!

MacBook Pro 15,4" anti-glare, 2,2 Ghz Quad i7 8Gig intern? Welk jaar?

Over de software: Alleen de laatste versies van Flash en Acrobat niet verwijderd. Rest van de laatste software wel.
Ook veel andere dingen gedelete die van invloed zouden kunnen zijn, maar misschien zie ik iets belangrijks over het hoofd...

De Safari extensies die "disabled" zijn kun je ook weggooien, ze doen toch niet meer mee.

Probeer je User Login items ook eens wat leger te maken. Al die zooi opstarten vertraag je opstarten alleen maar en het kan de boel flink in de weg zitten.

of ik kijk helemaal verkeerd... (niet zo heel veel verstand hiervan)

Dat onderste stukje moet je naar kijken, daar zit spul tussen wat mee opgestart wordt.

Wat je jezelf moet afvragen is of je bijvoorbeeld Airport Base Station Agent iedere keer moet opstarten of dat die alleen nodig is wanneer je Airport Station in moet stellen. Of je Canon scanner-software iedere keer mee moet opstarten. Of je GoPro software iedere keer mee moet opstarten. Of je Airport Configuratieprogramma steeds moet opstarten...

Dat zijn al 4 die je er zo uit kunt gooien. De software zelf kun je laten staan maar het feit dat die programma's mee opstarten heeft naar mijn idee geen enkele zin.

Verder zou je dit nog kunnen proberen:

Usually issues with keyboards are rooted in the user's account, and to tackle them first go to the user library (in Lion you will have to press the Option key and choose the Library from the Finder's "Go" menu), and then go to the Preferences folder in the Library. In this folder locate and remove the file called "com.apple.HIToolbox.plist," which is one of two preference files for "human interface" devices such as keyboards. After doing this, go to the "ByHost" directory within the preferences folder and remove all files that start with "com.apple.HIToolbox" in their names (sorting the list alphabetically will help locate these files).

Deze misschien voor de Canon software?

En hier staat hoe je mogelijk de rest kunt verwijderen (zet de betreffende bestandjes eerst even in een mapje op je bureaublad of zo, dit is niet meteen zo definitief) https://discussions.apple.com/thread/3148754?start=0&tstart=0

Andere tips?

Vervolgens een toetsenprobleem (89 uio jkl m.) Reageren niet. Ook niet op extern toetsenbord)
Alles geprobeerd. Toetsen doen het in Single User Mode en in toetsenbordweergave (klein toetsenbordje op scherm) en in terminal wel.

klinkt als muistoetsen probleem.

Ga naar Systeemvoorkeuren -> Toegankelijkheid -> Muis en Trackpad
activeer muistoetsen uitvinken

van apple site:
"When Mouse Keys is enabled with one of these keyboards, you can use the keys 7,8,9, U, I, O, J, K, L, M, and '.' (period) to control movement of the mouse pointer and mouse clicking, but other numbers, letters, and keys cannot be used.

Maar ja, er draait ook zoveel zooi op die Mac dat een kleine "onderhoudsbeurt" in de software ook geen kwaad kan.

Als je dan toch in Systeemvoorkeuren -> Toegankelijkheid -> Muis en Trackpad bezig bent ga dan nog even een schermpje verder en klik op Opties (in dat laatste venster). Zorg dat het vinkje uit staat voor "Druk vijf keer op Option om muistoetsen te (de)activeren."

Nou, dat werkt!! Heeeel erg blij mee!
Geen idee hoe dat zo is gekomen  

@Sypie, bedankt ook voor alle hulp om de boel een beetje op te schonen. Kan inderdaad nooit kwaad.

Nu ga ik verder om te kijken hoe ik de airport weer aan de gang krijg (dat was probleem 1).
Misschien dat die gewoon wél echt kapot is en ik iets met een dongel ofzo moet gaan proberen.

Onderhoudsbeurt? Ik zou zeggen: clean install!

Door Etrecheck kun je prima zien waar je troep zit.
