I like to access my Mac from work (Linux) and I wonder if it is possible without installing additional software like TeamViewer or ChickenVNC. I also noticed somewhere that it is possible to wake my Mac via WiFi. What is needed for that (Mac has to be plugged in? Do I have to be in the same Network?) and how do I do it?

This should be two questions 1) remote access(VNC is built into Mac) and 2) wake on WiFi –  Mark Mar 4 '13 at 9:26
    
I will recommend some other solutions like GoToMyPC or LogMeIn. VNC works like, well, crap over Internet, at least for me. Also, your company might block or limit speed of VNC. Solutions like LogMeIn are more stable. Or if you're a pro, SSH. Works like a charm! –  Shane Hsu Mar 4 '13 at 11:42

Part 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 this screen with password and supply a password

Part 2 - WiFi Wakeup

Still in System Preferences go to Energy Saver. You can only do this with the Mac running on power (if its a portable), but you should see an option to tick called Wake for Wi-Fi Network Access.

10.8.2 Problem - if you're running the latest public release of Mountain Lion you may find this doesn't work (detailed here -> https://discussions.apple.com/thread/4160837) however if you have access to a developer account, 10.8.3 reports to fix this. I can confirm this works under 10.8.3 on a MBPr 2012 model.

Thanks. I'll try that! And no problem for me with a developer account :) Can I also use screen sharing to get access to my Linux workstation? –  DaPhil Mar 4 '13 at 10:42
    
No, you'll need a VNC client for that. –  sgtbeano Mar 4 '13 at 11:08
    
May I ask another question: How do I wake up my Mac? Do I have to do additional stuff or does it work right away when I try to establish a connection? –  DaPhil Mar 6 '13 at 10:46
    
It think it depends on your router, I know with mine I have to forward WOL requests to a specific client IP using a setting in my router's firmware and also port forwarding. –  sgtbeano Mar 6 '13 at 14:40
    
I was wrong in my first comment, you can use the built in screen sharing to access any other OS which has a VNC server. The easiet way to do this is to issue CMD+K when you're in finder to open the 'Connect to Server' dialog. Then just typ 'VNC://IP or Name' where IP or Name is either the IP of the machine you want to connect to, or the FQD of the machine. –  sgtbeano Jun 3 '13 at 11:43
