I have two Mac minis that I just upgraded to El Capitan - both are headless so I use Apple Remote Desktop to manage them - after the upgrade I can't control either mini. I can observe both, but not control. I can guarantee it's the OS because I did a wipe and install on both and both exhibit the same problem.
Any suggestions?
Mac mini (Late 2012), OS X El Capitan (10.11.3)
You should be tried to disable rootless on OS X El Capitan. Before you install client software.
Follow these steps I'm sure you can install client software on your iMac 🙂
1st: Restart your Mac.
2rd: Hold command + R until you come to the recovery mode.
3nd: Open terminal and type " csrutil disable" to disable rootless mode.
4th: Reboot your mac and install client software without the warning.
Good luck, Guys
Other than disabling SIP (aka rootless mode), that did nothing to solve the problem. I can still view the login screen but I cannot remote control either machine.
Did you check to see if the user settings still allow control in the Remote Management Pref Pane?
Apple Remote Desktop no longer works after upgrading to El Capitan on two Mac minis
