macOS 10.13.1 bitcoinCore 0.15.1 downloaded from bitcoin.org Synology DSM 6.1.4-15217 Update 2
When I first start bitcoinCore , I select a folder on my Synology NAS.
When I validate, an error message pops up: "Cannot brain a lock on data directory / Volumes/home. Bitcoin Core is probably already running. Operation not supported"
After I acknowledge by clicking on the OK button, the application closes.
If I start the application again, the same error message appears without prompting me for a new folder.
This is reproducible 100% of the time.
The only error message I found was in /var/log/syslog: iMac com.apple.xpc.launchd[1] (org.bitcoinfoundation.Bitcoin-Qt.22648[7797]): Service exited with abnormal code: 1
