MacOS – Command + C does not always work on first try on MacOS

copy/pastehigh sierramacos

Command + C does not always work on first try on any of my four Macs. I often highlight text, press Command + C, head to another window, press Command + V only to find that the original text did not copy.

I recently installed a fresh copy of macOS High Sierra and I continue to run into this issue, particularly in RStudio.^* The issue never occurs on my PCs.

Do others have this issue? How can I resolve this?

^*I use bettersnaptool and enable three finger dragging, but the issue still appears when I disable them.

I think it's possible for Apple's Continuity Universal Clipboard feature to cause something like this, depending on the quality of the signal connection with any nearby iOS devices.

Perhaps try turning off "Allow Handoff between this Mac and your iCloud devices" in System Preferences > General and see if that helps.

MacOS – Parental Controls Always Allow does not work

This gave me enough info to fix the Minecraft launcher. The prior answer works, but has an ugly menu name, which my son would pester me about. So instead, I fixed the Minecraft.app setup.

In a nutshell, in terminal:

cd /Applications/Minecraft/Contents/MacOS
mv JavaApplicationStub Minecraft
cat > JavaApplicationStub << EOF
#!/bin/sh

exec `dirname $0`/Minecraft "$@"
EOF
chmod +x ./JavaApplicationStub

Basically, it would appear that ParentalControls expects the application being run to match the name of the executable (which is not the case with the distributed app: It's Minecraft.app, and JavaApplicationStub), so by moving the executable to match the app name, it works. I had to create a shell script to actually exec the executable because I got "Path not found" otherwise.

This seemed to work.

I only put this here because it worked for me. If you do not understand the code block again, please keep in mind you might have to re-download the app (or make a copy first).

IMac – Parental Controls Always Allow does not work for Avid Media Composer

I found this problem too! Turn off parental control and it works fine. Interesting as I have two Mac Pros and one with PCs on does allow MC to work. The other with the PCs on and it does not. I suppose best answer is to turn off Parental Controls for an separate account just for users whom use AVID.
