Continual (months) crashing of my MacBook Pro (13-inch, 2018) running High Sierra (10.13.6)

Thanks I will get back to you in more detail tomorrow it is getting late here.

First thing is you have McAfee installed. Macs do not need software like this

there are no viruses that affect the mac, this could be the source of your troubles

as it probably flags up files for deletion which may in fact be system files.

Apps like that are not necessary they just use up system resources for no

benefit. Go to the McAfee website and get the full uninstall instructions.

Simply deleting the app will not do.

Also looks like you have adware/ malware from 2013 install the free version

of https://www.malwarebytes.com/mac/

I would also consider reinstalling macOS High Sierra so download the installer app from here,

How to upgrade to macOS High Sierra - Apple Support

Go to Section 4 and click on Get macOS High Sierra.

This will connect you to the App Store High Sierra page

it should say Get or Download.

This will download Install macOS High Sierra.app to your Applications folder.

Make a bootable USB installer using these instructions.

How to create a bootable installer for macOS – Apple Support

You can create the USB now if you want and await any further instructions tomorrow.

Doing an in place reinstall of the OS will reset system files and caches and should improve your

macs performance. Note this is not a clean install where you erase the mac and start afresh.

But leave that till tomorrow.

Delete these files & restart..

/Library/LaunchAgents/de.novamedia.VodafoneDeviceObserver.plist

/Library/LaunchDaemons/com.mcafee.ssm.Eupdate.plist
/Library/LaunchDaemons/com.mcafee.ssm.ScanFactory.plist
/Library/LaunchDaemons/com.mcafee.ssm.ScanManager.plist
/Library/LaunchDaemons/com.mcafee.virusscan.fmpd.plist

/Library/LaunchDaemons/com.mcafee.agent.macompat.plist

/Library/LaunchDaemons/com.mcafee.agent.macmn.plist

/Library/LaunchDaemons/com.mcafee.agent.ma.plist

/Library/LaunchAgents/com.mcafee.menulet.plist

/Library/LaunchAgents/com.mcafee.reporter.plist

Delete these 3 files & Restart...

  /Library/LaunchDaemons/com.easeus.dataprotectbackup.plist

  ~/Library/LaunchAgents/com.adobe.ARM.***.plist

  ~/Library/LaunchAgents/com.apple.FolderActions.enabled.plist

~ tilde indicates hidden Local Library

Apple hid the Users' Library folders...

1. From the Finder, select the Go menu at top of the screen, and choose Go to Folder.
2. In the window that opens, enter ~/Library, and click Go.

Glad it's doing better, but...

/Library/LaunchAgents/com.mcafee.reporter.plist

/Library/LaunchAgents/com.mcafee.menulet.plist

/Library/LaunchDaemons/com.mcafee.virusscan.fmpd.plist

Safe Boot, (holding Shif startup), can you Trash them in Safe Mode?


Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

Get rid of McAfee.

They force us to use McAfee at work, and it is far worse than its cure. All the Mac users would throw it out in a heart beat if they could, but the Windows based security group has the authority and they do not care about productivity, they just want to make sure the corporate network is secure.

Your /etc/hosts file is corrupt.

It should look like this

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1	localhost
255.255.255.255	broadcasthost
::1             localhost

Still have these...

Launch Agents:
  [Running] com.mcafee.menulet.plist
  [Running] com.mcafee.reporter.plist
Launch Daemons:
  [Running] com.mcafee.virusscan.fmpd.plist

Hold Option or alt key when selecting Find to Find All.

Find all for Name Contains...

You can delete them from that withinFaF.

Is the mac yours or the Universities, inform them of their poor choice in getting you to install software that serves no benefit and is more likely to cause problems than solve them.

Which OS are you actually running on your mac. You have stated in your title that you are on macOS High Sierra

if you are on a later version it could be macOS Mojave or macOS Catalina, even so the App Store should allow

you to download it. But if you are running a newer version of macOS I do not want you to be installing an older

version as this will cause even more problems.

Please be careful what you allow other people to see in your screenshots. I can see your e-mail address and name, these shouldn't be included in case other unscrupulous people try to contact you.

I will ask for the screenshot to be removed.

I will reply here tomorrow.
