Subject: [PATCH] [remote dev] config share: fix sharing config between
 different frontend processes on macOS (IJPL-192726)

It appears that on macOS only an 'ENTRY_CREATE' event is fired when a new file is created and some content is written to it (on Windows and Linux both 'ENTRY_CREATE' and 'ENTRY_MODIFY' are fired).
