macOS Mojave 10.14.6 Schermbeveiliging slaat 40 seconden alles vast

Sinds enige tijd krijg ik mijn Macbook Pro maar moeilijk wakker als deze in schermbeveiliging staat. Het duurt zo’n 40 seconden voor er iets gebeurd. De totale computer is bevroren. Spatiebalk, muisklik, esc, starttoets (niet te lang) indrukken; niets helpt.

Ik heb een eigen fotomap en als eerste dacht ik dat daar een corrupte foto in zou kunnen staan. Maar… de bronmap openen bij het kiezen van een basisset in de systeemvoorkeuren ‘Bureaublad en Schermbeveiliging’ duurt het ook zo’n 40 seconden. Mijn eigen fotomap daar weggehaald maar als ik daarna een basisset activeer blijft het probleem bestaan.

Ook met de interactive hoeken krijg ik eerst alleen de klok (niet bewegend) te zien en na een tijdje de cursor. Interactieve hoeken uit gezet, klokweergave uit gezet, herstart met cmd - alt- P_ R, laatste systeemupdate:

NIETS HELPT! Jullie wel?

Heb je de recente veiligheidsupdate voor Mojave geïnstalleerd? Zo ja, dan zou dat weleens de oorzaak kunnen zijn.

Oef, ja dat wel. Ik wacht eerst altijd een paar dagen maar las geen bijzonderheden.

Dan maar afwachten tot de volgende update hopelijk is het dan verholpen…

De betreffende update is inmiddels ingetrokken, dus er zal binnenkort wel een nieuwe update komen. Meer details vind je hier: https://mrmacintosh.com/mojave-2020-005-security-update-causing-major-problems-updated/

Mocht je er gelijk vanaf willen: in recovery mode opstarten en dan macOS opnieuw installeren repareert de boel. Duurt ff, maar dan heb je ook wat. ?

Kwadraatje bedankt!

Gelukkig is dat het enige probleem dat ik nu heb. Schermbeveiliging heb ik uitgezet. Ik klap 'm wel gewoon dicht.

Ik blijf het vreemd vinden dat er updates worden uitgegeven die bugs bevatten.

Een back-up terugzetten is ook weer zo wat want ik heb al veel gedaan intussen…

OS opnieuw installeren is me de moeite niet waard.

Maar ja, ik heb geduld.

Je hoeft geen backup terug te zetten: gewoon het OS opnieuw installeren is voldoende (45 minuten duurt dat ongeveer). Je eigen bestanden worden niet aangeraakt.

Het probleem met die kleine updates is waarschijnlijk dat er weinig betatesters aan meedoen. De meeste zijn druk in de weer met Big Sur enzo.

En dat wordt dan de laatste OS van voor de update begrijp ik?

Klopt. Ik heb het zelf ook gedaan: je krijgt dan de actuele versie van Mojave excl. de gammele veiligheidsupdate.

Super! Dank je wel!!!

Inmiddels is er een nieuwe macOS Supplemental Update voor Mojave, die de boel ook zou moeten herstellen.

De macOS Supplemental Update voor Mojave geïnstalleerd.

Helaaaaas, het probleem blijft hetzelfde. Afwachten op de volgende update en voorlopig maar alleen de ‘Energiestand’ gebruiken.

Kwadraatje, bedankt voor je reacties!

Ik denk niet dat er nog (grote updates) voor Mojave komen… En inmiddels denk ik ook dat jouw probleem toch iets specifieks voor jouw Mac is. Hoe lang geleden is “enige tijd”? En zou je even een rapportje met Etrecheck kunnen maken, en het resultaat hier posten?

‘Enige tijd’ is 2 maanden denk ik.

Zoals je ziet heb ik heel wat 32 bit programma’s. Dat is ook de reden dat ik niet hoger ben gegaan qua OS.

Etrecheck geeft geen Major problemen. Ik gebruik dit voor het eerst. Zit er veel narigheid in? Hier het rapport.

Twee maanden geleden… Dan kan die laatste veiligheidsupdate dus nooit de oorzaak zijn. Had ik veel eerder naar moeten vragen natuurlijk. ?

Ik heb nu wel een vermoeden waar de oorzaak van die vertraging gezocht moet worden: Antivirus software: Avast, Trusteer, Apple, and Malwarebytes

Dat is behoorlijke overkill: met het spul van Apple en Malwarebytes ben je wel voorzien. Tenzij je heel zwaarwegende redenen hebt om Avast en Trusteer te blijven gebruiken, zou ik die eraf gooien (met behulp van de uninstall software die beide makers volgens mij aanbieden). En datzelfde geldt ook voor het nogal nutteloze CleanMyMac. In zijn algemeenheid geldt kun je dat soort ‘handige tools’ maar beter links laten liggen.

Kwadraatje, ik heb opruiming gehouden en een en ander weggemikt: geen resultaat.

Het ‘probleem’ blijft bestaan. Afijn, ik zet schermbeveiliging uit, dan heb ik er ook geen last van…

Bedankt voor je hulp!

Ik ben eigenlijk wel benieuwd of meer mensen dit hebben. - op mijn iMac 2017, ook Mojave, gebeurt hetzelfde.

Nou is een probleem dat zichzelf binnen een minuut oplost natuurlijk geen halszaak, maar raar blijft het.

@ tarmac58: een geruststelling om te lezen dat ik dus niet de enige ben!

Ik ben ook benieuwd of anderen daar ook last van hebben…
