Wacom One Tablet Not Connecting – Troubleshooting Guide

macoswacom

I have a Wacom One attached via mini-USB to my macbook pro 2020 running Catalina. This device is still supported under Catalina / macOS 10.15:

The Wacom driver was successfully installed and can be seen as running via Activity Monitor :

The various settings were also set properly:

Settings | Input Monitoring

Settings | Security & Privacy | Accessibility

However the Wacom Desktop Center reports that the tablet is not connected:

What else should I check/do ?

Update I rebooted with the Wacom One connected but still get the "No Device Connected" fro the Desktop Center.

Best Answer

Well well. I plugged in my iPhone and the Wacome One woke up!

What does the first action have to do with the second? Apparently the "tremendous weight" of the usb-c cable for the iPhone - which was a bit entangled with the mini-USB cable to the Wacom - was just enough to put the Wacom connector out of sorts. Jiggling the cable to the iPhone apparently undid that "flakey cable" issue.

So the only potential value now to this question is to confirm YES the Wacom One is working (surprisingly I might add) with macOS Catalina.

Update Apparently there is a specific power cord for Wacom that has a few parts including hdmi, power cable, mini-usb. I must have tossed it / lost it some time ago. So this device is a small-ish brick now.

MacOS – Run NRPE on Boot Without a Logged In User

Citing http://launchd.info:

~/Library/LaunchAgents and /Library/LaunchAgents are used for the currently logged in user.
/Library/LaunchDaemons is for running things as root ( or the user specified with the UserName key) when the machine boots.

The key (no pun intended), however, is that plists placed in /Library/LaunchDaemons/ must be owned by root:wheel and should be chmod 644.

So, just because nrpe creates a plist does not mean that it will run on boot without login.

I installed it via brew myself, and at the end it says:

To have launchd start nrpe at login:
  ln -sfv /usr/local/opt/nrpe/*.plist ~/Library/LaunchAgents
Then to load nrpe now:
  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.nrpe.plist

I would recommend that you do this, instead:

chmod 644 /usr/local/opt/nrpe/homebrew.mxcl.nrpe.plist

sudo chown root:wheel /usr/local/opt/nrpe/homebrew.mxcl.nrpe.plist

sudo ln /usr/local/opt/nrpe/homebrew.mxcl.nrpe.plist /Library/LaunchDaemons/homebrew.mxcl.nrpe.plist

The first line makes sure that the permissions are correct.

The second line makes sure that the ownership is correct

The third/last line links the file from /usr/local/opt/nrpe/ to /Library/LaunchDaemons (note the absence of a ~ which is intentional).

Then you need to make sure that the file does not exist in ~/LaunchAgents, which would be confusing:

rm -f "$HOME/Library/LaunchAgents/homebrew.mxcl.nrpe.plist"

That will delete the file (if it exists).

Important

By placing the file in /Library/LaunchDaemons you will be telling nrpe to run as root. That may be OK, or it may be a very bad idea. I don't know the answer to that question. However, to be safe I would make it explicitly run as a user other than root unless I was absolutely sure. Also, I would use launchd's ability to log errors to see if it is running OK.

To do this you will need to edit the plist mentioned above. Here is the file as it is originally created, as of 2016/04/20:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>org.nrpe.agent</string>
  <key>ProgramArguments</key>
  <array>
    <string>/usr/local/bin/nrpe</string>
    <string>-c</string>
    <string>/usr/local/etc/nrpe.cfg</string>
    <string>-d</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
  <key>ServiceDescription</key>
  <string>Homebrew NRPE Agent</string>
  <key>Debug</key>
  <true/>
</dict>
</plist>

and here is the version that I would recommend:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Debug</key>
    <true/>
    <key>GroupName</key>
    <string>staff</string>
    <key>InitGroups</key>
    <true/>
    <key>Label</key>
    <string>org.nrpe.agent</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/bin/nrpe</string>
        <string>-c</string>
        <string>/usr/local/etc/nrpe.cfg</string>
        <string>-d</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>ServiceDescription</key>
    <string>Homebrew NRPE Agent</string>
    <key>StandardErrorPath</key>
    <string>/tmp/org.nrpe.agent.stderr.log</string>
    <key>StandardOutPath</key>
    <string>/tmp/org.nrpe.agent.stdout.log</string>
    <key>UserName</key>
    <string>INSERTUSERNAMEHERE</string>
</dict>
</plist>

Replace INSERTUSERNAMEHERE with the actual username of the user that you want nrpe to run as.

Deprecated

Note that according to LaunchControl (which is the best app out there for managing launchd plists) the Debug key is deprecated for OS X 10.10 and will be ignored.

Reboot

Once you have the file in place, the best way to test it will be to reboot the system and do NOT log in on console. Instead, after the boot process is complete, log in via ssh and make sure that the process is running, and check the two log files to see what, if anything, you see there.

I hope this helps.

ps - spend $10 on LaunchControl. It's a great app. There is no registration code so you don't have to pay for it, but you should because the developer trusts you to if you use the app.

Wacom Tablet Error – Endless Error Messages in OS X System Log

Solution: I have completely uninstalled Wacom's tablet software 6.3.16-12 and switched back to 6.3.15-3. Also, be sure to remove all preferences files including the following leftovers:

/Volumes/MacBook/Library/Internet/Plug-Ins/WacomTabletPlugin.plugin
/Volumes/MacBook/Library/PreferencePanes/WacomTablet.prefpane
/Volumes/MacBook/Library/Frameworks/WacomMultiTouch.framework
/Volumes/MacBook/System/Library/Extensions/Wacom/Tablet.kext
/Volumes/MacBook/Library/Receipts/Wacom/Tablet/Docs.txt
/Volumes/MacBook/Users/yourusername/Desktop/Preferences.wacomprefs
/Volumes/MacBook/Users/yourusername/Library/Preferences/com.wacom.wacomtouch.prefs
/Volumes/MacBook/Users/yourusername/Library/Preferences/com.wacom.wacomtablet.prefs
/Volumes/MacBook/Library/LaunchAgents/com.wacom.wacomtablet.plist
/Volumes/MacBook/private/var/db/receipts/com.wacom.TabletInstaller.plist
/Volumes/MacBook/private/var/db/receipts/com.wacom.TabletInstaller.bom
/Volumes/MacBook/Users/yourusername/Library/Application/Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/com.wacom.removewacomtablet.sfl
/Volumes/MacBook/Users/yourusername/Library/Saved/Application/State/com.wacom.RemoveWacomTablet.savedState
/Volumes/MacBook/Users/yourusername/Library/Preferences/com.wacom.RemoveWacomTablet.plist

I have spent hours on debugging. These error messages are definitely related to the Wacom Tablet Software update 6.3.16-12. Morever it’s related to random system crashes and strange command click behaviors!
