I've decided to start playing runescape again, but it won't work on my macbook. I have the newest version of Java, and I've tried with Safari, Opera, and Firefox.

Has RuneScape ever worked on your Macbook? Do you get any kind of error message when you try to play? Also, do you remember that little thing that you have to agree to when you first play RuneScape on any computer? Are you sure you're allowing it?

I get this:

 

Error_game_js5io - Io error.

 

Runescape was unable to communicate reliably with the update server. This is most likely caused by firewall/antivirus/filtering software on your computer, or a fault with your network hardware/software. To resolve this:

 

 

 

# It may just be that the game has been updated since you loaded it, try rebooting your computer and reloading the game.

 

 

 

# If that doesn't help then try using a different world at another location.

 

 

 

# If that doesn't help then make sure your firewall/antivirus/filtering software is set to not interfere with the RuneScape download.

 

 

 

# If that doesn't help then external filtering software may be causing the problem. Please ask your network adminstrator/ISP for assistance.

 

 

 

If problems persist then please refer to our technical FAQ which can be found in the FAQ section of our website.

 

 

 

And yeah I have everything enabled.

Make sure that Java is turned on in your Safari preferences. You may want to turn off any additional security programs that you have on your computer, as they may be interfering with Runescape. If nothing works, you can post a question on the Apple site and someone there should be able to help you.
