I am running a modded version of Minecraft on my computer, which is a Mac Mini running OSX. I have the latest update of Java 7 and I am running the FTB Unleashed v1.1.3 launcher and have not had issues in the past. I have reset both the launcher and the machine a few times and have had no success so far.

Here is a screenshot of my launcher:

Any help or advice would be very much appreciated.

    Try resizing the game (this isn't your launcher btw). Then try giving it more ram. IIRC unleashed was really poorly optimized. DW20 1.6 fixed that though.

  • @Chipperyman Thanks for clarifying that the client is not the launcher. Resized the client while the bars were present, but the problem remained, but when I relaunched Unleashed they were gone. As I am new to FTB, I'm not sure what IIRC is, or DW20 for that matter, but that will give me something that I can research. Also, if you answer the question, I'll upvote and use it as the solution.

  • IIRC = If I remember correctly; DW20 = Direwolf20 pack

Try adding my ram to the launcher. Click options at the top and drag the ram slider:

I believe unleashed requires at least 2.5GB ram to work properly and recommends at least 3. Don't drag it above 4, as it will mess with Java.

Also make sure you have 64-bit java on a Windows computer (this does not matter on OSX).

I also suggest switching to the Direwolf20 (DW20) 1.6.4 pack as it uses a newer version of Minecraft, has updated mods and is slightly moer optimized.
