bug#29883: Emacs server not detected in Mac OS High Sierra

[Artemio González López]

When a .tex file is opened in Emacs 25.3.1 under macOS 10.13.2 High Sierra by 
double-clicking on it always launches a second instance of Emacs, even if a 
server process is already running (launched by a “(server-start)” line at the 
beginning of my .emacs file). This problem did not occur in the previous system 
(macOS 10.12 Sierra).

In GNU Emacs 25.3.1 (x86_64-apple-darwin13.4.0, NS appkit-1265.21 Version 
10.9.5 (Build 13F1911))
