I would like to load a specific firmware from https://support.apple.com/en-us/HT201518

My research shows the MacBook Pro early 2011 SMC 1.69f3 seems to be stable. I use links on apple website shows "page not found" when clicked on the update 1.5. Can someone please help me provide the SMC 1.69f3.

Are there places to download this software?

    What OS are you on? Firmware updates are usually included in OS updates & don't need to be done separately. Have you also checked what your current firmware version is? Your question is lacking in detail.

For most people, I recommend always going forward, never backward. I’m sure someone has squirreled away copies, but I don’t have any source I trust to get old firmware.

There are ways to flash firmware without Apple’s loader process - How to downgrade SMC firmware

As you notice, since the updates now happen when you install macOS updates and upgrades the older Apple page is archived and not maintained or migrated to the new hosting support sites. In the case you seek to down level, I've not ever seen that work. I’m not saying you couldn’t be the first case to achieve that, but the issues tend to be failing hardware and not that the newer firmware has some bug Apple doesn’t then fix with even newer patch.

I’m not saying you’re wrong, just my experience is this hasn’t helped in the past. I hope you prove me wrong in this case and can report success getting the code and that it helps as you expect. Documenting it publicly and the checksum of known good firmware will be a service to everyone.

Keeping “obsolete” or “vintage” gear in full operation makes me very happy and is a worthy goal.

  • my macbook early 2011 has issues.. freezes and goes blank during boots.. and i realised i was not able to update boot rom beyond 87.0.0.0 and i updated the smc to 1.69f4 which makes the fans speed go very slow.. and any other version of smc firmware from the apples website makes just one fan spin... am stuck with 1.69f4.. my earlier 1.69f3 was stable and had no fan speed issues...

  • The flash back is going to be an issue. I’ve never seen Apple installers allow that even if someone squirreled away the upgrade package. How are you going to manage the downgrade? @RaviKumar
