    Check if you have a browser extension called BrowserProtect, and if so, remove it. Definitely worth checking this if Ryuug's suggestion above makes a difference.

    Instance started with command:
    "C:\Program Files\Java\jre6\bin\java.exe" -Xms512m -Xmx1024m -jar MultiMCLauncher.jar "<username>" "<session ID>" "MultiMC: minecraft" "854x480" "Mojang"

    Error occurred during initialization of VM
    Could not reserve enough space for object heap
    Could not create the Java virtual machine.



    Try reducing the -Xmx1024m to say -Xmx800m. If that works, then .. check if you have installed/running a freebie browser extension called BrowerProtect. If so, remove it (which may be hard as various trojans hide inside versions of this and are hard to remove). Otherwise, can't help you, sorry.

    I've solved this (for us).

    1-line solution: remove BrowserProtect. Alas, this may be very very difficult.

    For deeply geek hints about what's going on here, see this: http://johnsrandommu...-this-heap-size


    Another hint: try opening a cmd tool, CD to the directory with the Minecraft.exe in it, and running "java -Xmx800m -jar Minecraft.exe" - if that works, try increasing the number from 800 towards 1024 and it should eventually break. For me, it broke at 920. If this doesn't work for 800 or even 512, then you have a different problem.

    I downloaded the ListDLL utility, and found a BrowserProtect DLL loaded into every Java process at address 0x10000000. This prevents JVM allocating a contiguous 1GB object heap, causing the "could not reserve enough space" message. A 1GB object heap (java -Xmx1024M) is the default setting for vanilla Minecraft and most minecraft-related apps.

    Removing browserProtect from Control Panel -> Add /Remove programs fixed it for us. However, there are lots of trojans out there buried inside BrowserProtect binaries and some of them can be very hard to eradicate.

    Works on my 10.6 2nd gen mac Air. Fails on my 10.5 1st gen mac Air. Both ran 1.7.3 fine.

    Naively fooling around with command line java shows a functionNotImplemented error from inside the GL library. Not sure if this is an OS-related graphics library thing, a Java version thing (mods never worked under 1.7.3 on the 10.5 system due to java versions either), or unsupported video hardware on the old mac Air now obsolete due to new lighting models.
