The HD5500 freeze issue

The Intel HD5500 freeze issue

Hello.

As some of you might be aware of, the relatively new Intel HD5500 broadwell IGPU is supported in OS X by doing some changes to the pre-allocated memory to the GPU to make it work. However it is plagued with a certain freeze issue that freezes the OS and requires a reboot, very much like the Fermi Freeze that was rampant for Nvidia users before.

Some sources has mentioned that the issue is fixed in El Capitan, but I haven't seen anyone really confirm it other than in comments on a blog.

Could some owners of a HD5500 who know they had a freeze issue before in Yosemite confirm that the issue is indeed fixed? It would make or break a laptop purchase I'm about to make, so a confirmation would mean a lot.

Thank you for testing if you decide to do so.

Can you provide links to these blogs so I can have a read? If promissing I will install and test over the weekend and report back if there is no freezing....

I had posted it here confirming the screen freeze fix with El Capitan.
I have a Dell Latitude E7450 with HD 5500. The freeze continues even after upgrading to 10.10.4, so decided to test El Capitan. To my surprise it's been running pretty stable for the last few weeks without a freeze. Of course there will still be some unresolved issue like USB, but that's another topic.

Ok, so El Capitan breaks USB?
if it works without freezing then this is indeed good news i can complete fixing my install as i stopped due to the freezing issue which is bad for media play back for me...

Not broken, but it requires research/work...

In my opinion, it is better and easier to accommodate PCs with Intel USB2/USB3.

OK, I'll try get some time this weekend to work on it and see if i can get some love out of it. BTW i did a bit of reading and saw someone say that creating 10.11 using createinstall media would fail?

I've had no issue using createinstallmedia. You do need enough space...

The usual 8gb is enough or need more than that?

8GB is enough. I was trying to combine 10.10 and 10.11 on a 16GB stick. It works, but you can't go overboard on the CLOVER EFI size (it was MBR so size of Clover partition is your choice). And in that scenario, probably better to give a bit more to 10.11. The error messages when you run out of space are not very good at indicating the actual problem.

Ok thanks, didnt want to go get a bigger USB, I've got lots of 8gb USB sticks.
