Continuous flood of errors - wirelessproxd, identityservicesd, sharingd

Ah, thanks...  Adware - Adware detected, remove that.

~/Library/LaunchAgents/com.appcart.AppCart.plist

~/Library/Application Support/AppPolicy/AppCart -i -c 216107 -isn AF2644A8-9299-4C3C-AD53-CC918E901669

Remove these...

~/Library/LaunchAgents/com.myheritage.familytreebuilder.checkupdates.plist

~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

/Library/LaunchAgents/com.motorola.MDMUpdater.plist

Restart, you're also running an awful lot of stuff for only 16 GB of RAM, Free RAM: 21 MB, but see how things go after restarting after removal.

Did you just do an update or upgrade?

EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Pastebin is a good place to paste the whole report...

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.

pple hid the Users' Library folders...

Method 1:

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.

Method 2:

1 Go to the Finder (or desktop).

2 Hold the Option key on your keyboard, and click the Go menu at the top of the screen.

3 With the Go menu open, you'll notice that pressing and releasing Option will display or hide the Library choice in this menu.

4 Select Library from the Go menu (while holding down Option) to access the hidden folder.

Method 3:

1 Click anywhere on the desktop so Finder is the name of the foreground app shown at the upper left.

2 Press Command+Shift+H

3 With your home folder open, press Command+J. This the only place you'll see a check box to Show Library Folder. Turn it on.

4 From now on, your user account Library folder will be visible without having to use special keys or commands to get there.

Great news Chuck, tough to say which it was...

identityservicesd handles iCloud/iMessage/FaceTime background stuff.

wirelessproxd is the Wireless Proxy Daemon. It’s a service that handles certain networking functions, including AirDrop.

sharingd is the Sharing Daemon that enables AirDrop, Shared Computers, and Remote Disc in the Finder.

My guess would be the 2nd one.

Are you actually having a problem, or just seeing things you don't understand in the logs?
