Macbook Pro Power – Turning Off Power Chime

macbook promacospower

On new Macbook Pro, Power Chime runs. Whenever I delete from core services it comes right back. It makes a sound when plugging in your power cord even when the volume is at 0%.

The solution I have now to disable this annoying sound is an AppleScript application that runs on login to kill the process via terminal. Is there a better way?

The solution is to set ChimeOnNoHardware to true instead of setting ChimeOnAllHardware to false (note, No instead of All):

defaults write com.apple.PowerChime ChimeOnNoHardware -bool true
killall PowerChime

MacBook – MAMP Pro failing to launch (thesql)

Due to trying to get my local server up and running again, I installed and got working XAMPP, which then had a knock on effect of allowing MAMP Pro to display a decent error message (instead of continually working) and allow the options on the interface to be active again. MySQL was running but Apache couldn't launch. Also, although I could change the settings on the MAMP interface, none would save. looking at permissions and ownership, the app and files were owned by root (but not sure that had any refection on the issue).

@bassplayer7 gave me pointers to the uninstaller (something I didn't know existed), which due to permissions couldn't actually do anything. So I found these excellent instructions: https://stackoverflow.com/questions/11855247/mamp-pro-restore-root-user-uninstall Which cleaned it off completely.

I then did a system restart, re-installed MAMP Pro completely fresh, and it all worked first time. Albeit without any databases, hosts or settings.

You do have backups, right?

MacOS – How to create a scheduled task that deletes files of a certain name everyday

Add the following to your crontab (run env EDITOR=nano crontab -e to edit your crontab):

@daily /usr/bin/osascript -e 'tell application "Finder" to delete (every file of folder "Macintosh HD:Users:username:Downloads" whose name starts with "message" and modification date is less than (get current date) - 2 * days)'

^{Untested as I have no such files on my system. Keep backups and make sure you've got the right path.}
