application is already running ? (Peak Pro)

Howdy luminousmusic,

It sounds like you are unable to run an app because a copy of that app is already running.

Try force quitting the appwith these steps from the article named:

Mac OS X: How to quit an unresponsive application using Force Quit

http://support.apple.com/kb/HT3411

To force quit an application, choose Force Quit from the Apple menu (or press Command-Option-Esc), then choose the unresponsive application in the Force Quit window, and click Force Quit.

Thank you for using Apple Support Communities.

Cheers,

Sterling

Same problem for me, and peak was to work fine before to update of MAC OS 10.9.

Apple did a mess again, that's it.

Hey man! Try to turn off your WIFI and open PEAK PRO 🙂 Don't ask me why, but I figured out that for some reason when I'm not connected I can run the program without problems hehe Hope it helps! Cheers!!!

I solved by deleting a file named "database.lock"

inside folder

/var/folders/wc/wg2qdxgn0fg0pcp_jk6x6wlc0000gn/T/.AddressBookLocks/

(the name of the folder below "wc" is problably randomly generated)

I found this file by listing all open files in use by Peak (while it had message window open)

@Dan

The simplest way is to use the app "Activity Monitor", select PeakPro in the list of All Processes running, press Cmd-i (or click the small "i" at the top bar), then choose the tab "Open Files and Ports".

Otherwise use the Terminal app, and run "lsof -p <PID>" (where PID is the process id of Peak, a number like 2983), you get the PID by "ps -ef | grep Peak | grep -v Grep", the second field it's its PID. Of course the message box of PeakPro must be still present. This worked for me while I was not in Internet (i.e. WiFi disabled / no Ethernet cable etc), otherwise after I deleted the database.lock file, it was immediately recreated: weird, isn't it?

Thank you, MarceloVasco! Turning off Wi-Fi enabled me to use Peak LE 5.2. However did you come up with this solution?

I don't know how he did that, because I did a try, with the wifi on or off, it don't work at all lol

How do you list all the open files in use by Peak ?

Double-weird !

If I disconnect the network, Peak Pro starts up.

I can reconnect after the app starts with no problem.

However, the database.lock trick does not work.
