Hey,

I installed the 10.9 Beta yesterday and so far I'm really surprised how stable it is. The one thing I noticed though is that the RAM allocates to the HD4000 graphic processor in my 13" rMBP has increased from 768 MB to 1024 MB. I'm not sure if this is just per accident, because my Mac just had more free RAM to allocate or if they made sure 1024 MB are always allocated to the graphic processor? Can anyone confirm my findings?

Best

Same thing on my 15in retina

My Intel HD Graphics 4000 is now saying 1024 in my 15in macbook pro

Same here.

Retina MBP 15" - 16Gb RAM



ML allocated 512Mb or memory for the Intel HD 4000. Mavericks allocates 1024Mb.

It may explain why scrolling is smoother in general... :)

I have just gone back to a fresh Mountain Lion installation and it show 768 MB again, so I pretty much think this is confirmed. I have 8 GB installed.

Is it normal that on a 15" rMBP the allocated RAM to the HD4000 is 512MB? I have 16GB total. I'm just asking because Galatian just said that there are 768MB allocated on his 13" rMBP. Is it because there's only one graphics card?

Cause I've been only using the HD4000 and been noticing some lag overall.. was wondering if it was possible to allocate more memory and if 512MB is normal or not.

Sorry for the off topic.

512MB under Mountain Lion is normal. Mavericks though seems to allocate 1024MB.

This is confirmed that OSX Mavericks has increased the RAM for the Intel HD 4000 up to 1024MB up from 512MB. This is necessary to improve UI scrolling and better overall performance. In doing this, Apple made some changes for better Battery life as well and moving Core Animation to the GPU for better GPU based rendering. The physical amount of RAM installed in your machine will not be affected, its just how its allocated and distributed is the change. Its a very welcoming change in my opinion!

Should be a nice boost for the rMBP 13" owners especially.
they must be confident in their memory compression technology.

Same for my 2012 13" MBP

Any possibility this could transfer over into bootcamp Windows 7 too? I would love the extra memory for gaming.
