Disable Spectre and Meltdown patch

Hi!


I was wondering if there is a way to disable Spectre and Meltdown patches. Some sort of boot flag maybe?


Thank you 🙂


And before someone says something about security or about how little performance I loose in regular use cases. I know. I accept the risks. It's my product. I want to use it in it's full potential. Well... I need to use it in it's full potential.

You can't disable it if you updated to 10.13.3, it's embedded, unless your computer shipped with an earlier version of the OS and you can internet restore back to that OS or you have a full installer of 10.13.1,or 13.2 and can roll back to that.


Personally I understand you concerns (i'm running a CPU rendering farm) but this is a volunteer forum. You are not speaking with Apple here and Apple does not respond to posts made here. If you have concern you would like Apple to know about go to www.apple.com/feedback

You are falling into the trap of thinking that "Apple" is a person. It is actually the world's largest company, with hundreds of thousands of employees. And the few employees (very few, BTW), who manage the forum do not have responding to posts such as yours in their job description, or even reading posts. About the only time a host sees a post is if a user at level 2 or higher reports it for a potential violation of the terms of use.

FWIW, I ran Geekbench before and after the OS updates

and found no noticeable differences in performance on

on all 4 Macs. The difference was not more than the

variance one sees between different test runs.


Whether Geekbench would be the right tool to determine

this remains to be seen.


Also, FWIW, I have noticed no difference in my normal usage which includes

a good deal of photo editing with 3 or 4 apps open.
