    I don't get it.

    I was able to upgrade my dedicated VRAM on just 8gb of ram to 512 VRAM

    But on my 16gb early 2013 Macbook Pro 15", Intel 4000 I only have 512mb dedicated VRAM...

    Can someone tell me if there is a fix? Or a way to increase the dedicated VRAM?

    OSX assigns vram on intel GPUs automatically. There's nothing to do on your end.

    There has to be a way. My 2011 8gb of ram MBPRO has 512mb of VRAM. It makes no sense...

    Integrated GPU VRAM cannot be changed. It's managed by OS X.

    Neither can the dedicated GPU VRAM be changed either.

    Non-retina 15" cMBPs with 2.3GHz i7 have 512MB NVIDIA GT 650M. Only 2.6 and 2.7GHz i7s have 1GB GT 650M.

    Umm, could you post a screen shot of your about this Mac, The HD 4000 has the ability to allocate up to 1024 MB of the RAM to VRAM, (if I remember 8 GB allows 512 MB so total available RAM would be 7.5 GB, 16 GB allows 1024 GB of VRAM total available RAM is 15 GB) but under OS X this is entirely automated and the amount will very depending on how much is utilized. The HD 4000 did not allocate well and only certain models allowed more than 512 MB of RAM to be utilized as VRAM. Under Windows is an entirely different story, it could be forced to 1024 MB of VRAM. I believe you are confusing with the HD 5000 which can be allowed up to 1536 MB of RAM to be allocated to VRAM if one has 16+ or more of total RAM. I know the MacBook Pro 13" did have the ability to load 1024 MB of RAM remember seeing some of the display models but the 15" did not since it has the dedicated card with 512 MB which is much more effective than 1024 MB of "vRAM" used from RAM.
