Booting Is Slow After Uninstalling Boot Camp.

Hey there. I just was just wondering if it's possible to revert the firmware on my Macbook Pro back to what it was before Boot Camp made all those EFI changes to it.



Even though i've untinstalled Windows and Boot Camp, it still takes forever after i hit the power button for the OS to start loading. It just sits on that grey screen with the Apple logo for like 2 mins before the spinning circle loads.



It didn't do this before Boot Camp. Thanks in advance.

    AFAIK, Bootcamp doesn't do anything to your firmware. The firmware updates that were provided for all Macs are what enabled Windows booting. Even without Bootcamp installed, an Intel Mac will boot from a Windows disc. Bootcamp partitions the drive and starts the Windows installation, which is basically the same as changing your startup drive to the Windows partition.



    Maybe you can boot up holding command-v to see where it's getting stuck.

    wow I thought I was the only one with this problem. I am at work right now, but I did wind up fixing the problem after asking around here, and tinkering with a few options. It has something to do with the partitioning and what is selected as your primary boot partition (if this helps at all lol). When I get back from work I'll boot up my computer and find the menu again, this is an easy fix.

    The Startup Disk settings are in the System Preferences.



    Reboot after doing that, and it should boot a sh!t load faster.
