Ik heb al van alles geprobeerd.
Imac opnieuw opstarten, FF weer verwijderen. terug zetten via TM (wil overigens ook niet)
Weet iemand raad?

Heb je al eens een nieuwe gebruiker aangemaakt, als die gebruiker ingelogd op je Mac, en gekeken of je dan nog steeds last hebt van dit probleem? Een etrecheck overzicht kan ook inzichten geven.

Het is dan veel makkelijker voor ons (en jijzelf trouwens ook) om deze foutmelding te vinden, en daarmee mogelijk ook de oorzaak ervan.

Ik zou overwegen om een schone installatie te doen (schijf wissen, macOS opnieuw installeren) en dan al die schoonmaak programma's die je geinstalleerd hebt (inclusief avast) achterwege te laten.

En dat naast 5 andere z.g. schoonmaak en beveiliging progs...

Flix: ik heb FF gewoon in de map Programma's staan....

Virtual disks: &#9432;
Firefox (disk4s2 - HFS+) /Volumes/Firefox : 168 MB (0 B free)
Physical disk: Disk Image 168 MB (0 B free)
Firefox (disk5s2 - HFS+) /Volumes/Firefox 1 : 168 MB (0 B free)
Physical disk: Disk Image 168 MB (0 B free)

Ik zou stante pede MacKeeper, en liefst ook CleanMyMac verwijderen...

En ik ben de feeds van mijn Rss reader ook kwijt.
Als die gegevens moeten zich ergens in de Bibliotheek in TM bevinden,maar waar.
Ik leefde in de veronderstelling dat je met 'terugzetten' vanuit TM alle gegevsn ook terug had....needus
Wie weet raad?

Geloof ik.

Dit is in ieder geval de map die ik af en toe weggooi als hij langzaam begint te worden en gaat stotteren met scrollen.

M'n bookmarks sync ik met Xmarks.
Maar Firefox heeft daar zelf ook een service voor.

Ik leefde in de veronderstelling dat je met 'terugzetten' vanuit TM alle gegevsn ook terug had.

Voor Safari: ~/Bibliotheek/Safari
FF: ~/Bibliotheek/Application Support/Firefox

Dat dénk je alleen maar volgens mij. De files zijn onzichtbaar.

Maar toevallig constateerde ik vorige week dat het léek of die map leeg was, maar ze bleken slechts onzichtbaar.

Wat ik bedoel te zeggen is dat mijn opmerking inderdaad wat off topic is.
