dump RAM from El Capitan

You can temporarely disable SIP and try OSXPmem again. it will very probably run, as Dialabrain suggests.

However I don't think the result will be a true result, but if that is not important (because it is the method of analysing that counts probably), why not try it.

Disabling/enabling SIP is easy and done in the RecoveryPartition.

I strongly suggest to re-enable SIP a soon as possible after your test.

dialabrain: if the app "works" it is almost certain that the result is not true, but it may not be important as i said before.

FWIW, I never said or implied "it will very probably run.". I actually said it still may not run. There's every chance it needs to be recompiled against the El Capitan kernel.

As I said already; no need for downgrading.

Virtualisation would not change the Ram handling of the (main) OSX.
