Hello, Yosemite (10.10) deprecated utmp i flavour of utmpx. but the screen software still uses utmp. according to the doc (pututxent) i tried a quick and dirty hack: (getUtxEnt(line)) followed by putUtxEnt(line); it is running, but no utmp is created. i need it, waiting that screen will integrate utmpx. Any idea would be appreciated. Thanks in advance. Rmgls
