    Hi guys, I have a late 2011 17inch MBP, everything was fine until I updated to High Sierra, now I am getting three beeps on startup and it isnt loading the OS. Seems the 3 beeps is usually associated with ram, but why immediately after the update? It will boot into safe mode and recognizes all of the Ram installed.

    Have you tried running the Macbook with one stick of ram?

    Perhaps it is just coincidence that the ram issue appeared with the change to High Sierra?

    Was High Sierra installed an upgrade over Sierra or clean installation?

    I haven't touched the ram yet. It was an upgrade over Sierra

    Personally, I would start with removing one stick and then the other as it could be a ram problem.

    Possibly related but have you had any gpu issues on your Macbook?

    What are your RAM specs? It's supposed to be PC3-10600, DDR3 1333 MHz, CL9.

    I've noted a few cases of something like this happening when someone has spec'd the wrong RAM. An update of some sort can cause the RAM suddenly not to work. Although it would usually be a firmware update I'd imagine.

    Thanks, looks like it's time to open it up.
    I had my motherboard and GPU replaced by Apple when they were still offering it, no issues since.

    It's worth first just trying to reseat the RAM IMO.

    Thanks guys! I reseated my ram and that seems to have fixed the issue, so it must have just been a coincidence. Strange how stuff like that works.

    I was lucky, I had no idea about the program or known issue, started having the graphics problems and took my laptop in to the Apple Store and they repaired it, this was all about a month before the program ended.

    Hi guys, I wanted to update this. The problem persisted after the ram reseat. I tried reinstalling High Sierra but that did not help. I have now used my time machine backup to go back to Sierra and the issue has not reappeard.
