Apple - Can I remotely access my Mac from Linux using screen sharing?

You can take either one of the following two approach:

1. VNC

This is pretty simple, you'll need to go to System Preferences → Screen Sharing and then click on Computer Settings. From there you can select VNC viewers may control screen with password: and supply a password.

2. Wi-Fi Wakeup

Go to System Preferences → Energy Saver. You can only do this with the Mac running on power (if it's a portable). You'll need to enable an option tick called Wake for Wi-Fi network access.

OS X Mountain Lion 10.8.2 Problem

If you're running this release of OS X Mountain Lion, you may find this doesn't work.

Q:

No Wake-on-LAN possible since updating to ML

Hi everybody,

since updating from OS X 10.7 to 10.8 (clean install), Wake-on-LAN does not work anymore. Setup: Mac mini (Early 2011) connected to Time Capsule (2nd gen) via devolo dLAN. Mac mini goes to sleep after 30 minutes and eventually disappears from the network. Sending Wake-On-LAN packets or using Back To My Mac fail, it simply won't wake up.

Wake-on-LAN worked smoothly under 10.7 after some problems. Any ideas?

Thanks and regards

Steffen

However, OS X Mountain Lion 10.8.3 fixed this.

Ubuntu has community wiki guide for the matter https://help.ubuntu.com/community/AppleRemoteDesktop
