MacBook Air beach balling frequently
My 2012 13” MacBook Air 1.8 GHz (5,2), running MacOS Mojave10.14.3 is hanging frequently.
It starts with a beach ball after which all processes come to a stand still. Left to itself the system goes into sleep mode. The same thing happens if the lid is closed. When reopened it tries to boot but fails after about 60% of progress. Left to itself, the screen goes white. After sometime there appears a folder with a question mark as if it is not able to locate the boot disk.
But it boot as expected after a forced switching off. It shows a kernel panic something like “failed after 5 attempts - quitting” on the previous boot.
This problem started following some adware attack. First it was Mackeeper which I tried to remove following all discussions on the topic killing all related files in appearing in Launch Agent, Launch Daemon in the ~\Library folder. I also used the “deleteMackeeper.sh” file suggested elsewhere. The problem persists. An Etrecheck showed a couple of problems with adware which were deleted but no improvement. I must add that my battery is failing (runs at 65 %).
Whenever the beach balling occurs, a file is created in the ~/Library folder with name “ApplicationSupport”. It has inside it only one file “ApplicationContents”. The ~/Library folder contains two files “Application Support” and “ApplicationSupport” (without any space between the words). There are also two files “Assistant” and “Assistants”. The file “Assistants” contains nothing and can’t be deleted. After every reboot I delete the “ApplicationSupport” file and it seems to help for some time. But the file is regenerated after every beach balling.
A First-Aid run in Disk Utility showed no problem and same is the case with an extended apple diagnostic check. Last night from a suggestion in MacRumors did scan with Malwarebytes and 9 issues were detected and cleaned. But the problem persists …
Any suggestion will be highly appreciated. Thanks.
Ist dies eine gute Frage?
