    Since I upgraded to 10.10 DP1, my Early 2011 MBP needs around 30seconds to boot. Actually, it spends the most of that time with an empty screen after the Apple logo is shown, and then, the "loading bar" appears and do it at normal speed. I have a 3rd party SSD with TRIM enabled, and boot time used to be 7 seconds in Mavericks. It's also slow when powering off.

    Has anyone else experienced this? Is there something I can do? :confused:


    P.S: I used this to enable trim, not sure if it's related with my problem

    I have a 15" late 2013 rMBP, and it is a few seconds slower to boot into Yosemite (DP1 & DP2) than in Mavericks, but I haven't seen a slow down to the scale your describing. I just figure that, in my case at least, it's just all the added debug information included.

    Did you do a fresh install? Because I didn't, and perhaps it's related to it. My slow down comes just after powering on the MPB, just after the sound it hangs for 15 secs waiting until the Apple logo appears and the progress bar goes on... and that step should happen almost instantly.

    As I've said before, my SSD is not official, and I had to activate the TRIM support manually with TRIM ENABLER for Yosemite instructions... :(

    Yes, I did a fresh install. I created a new partition using Disk Utility, and installed Yosemite on the new partition. And note: I have Windows 8 installed on a 3rd partition and it works well. Haven't had any problems with Windows or either version of Mac OS X. It is fun pressing Option while starting up and seeing 5 partitions (Mavericks, Yosemite, Recovery-10.9, Recovery-10.10, and Windows 8).

    Having a 3rd party SSD might have some part to do with it, as well.

    Fresh install on a separate partition for me on a late 2012 rMP, and marginally slower boot up on DP1 and DP2 but not noticeably. Same on shutdown.

    Thanks! It worked... Partially; now it boots up much faster, yes...
    However... Now I can't login into my user account, it stops on login screen with the beach ball spinning endlessly like this:

    Actually I noticed that the same happened to me when I just finished updating to DP2 preventing me to login, and suddenly after forcing the shutdown, it worked again (but with slow boot up).... Until now.

    pS: perhaps its time to go back to mavericks

    Boot up by holding CMD and R, then repair disk permissions. Upgrading from B1 to B2 screwed up permissions for me, and a repair fixed everything. Much smoother now.

    Hi, i have a macbook pro mid 2012 originally shipped with Mavericks, upgraded to Yosemite and now i have done a full clean install of El Capitan.
    I use the mac for mainly running music applications like Ableton live 9 suite, Sony sound forge and Traktor Pro, the last app in the list its recommended to not be installed until Native Instruments releases an update patch for El Capitan.

    MacBook Pro (13-inch, Mid 2012)
    2.5 GHz Intel Core i5
    8 GB 1600 MHz DDR3 from Crucial
    Intel HD Graphics 4000 1536 MB
    250 GB SSD from Crucial
    Trim enabled using Terminal.

    7 Seconds start up under Yosemite but double the time with El Capitan or even more. I had not done the SSD upgrade while i was using Mavericks so can not speak for that matter.
    I use CTRL+ALT+CMD+Eject to shut down the mac normally and it used to be a breeze.
    Shut Down time is almost like windows 10, the screen desktop background stays on for a couple of seconds and after that the wheel spins a couple of times before screen goes black and you can still see the front led light is on for a bit longer.
    Over all system is much faster and cooler than both previous versions of the OS in my experience and i do find changing the screen resolution form Default to the next one down the list makes the system and internet browsing much faster, pages load much smoother too but again is just what i am experiencing, some people say that the higher resolution the better.
    I also hav Mac Mini running Yosemite and comparing both El Capitan feels much more responsive.
    I do not think you would be able to speed up the boot time unless Apple decides to release system update some time soon in the future to address the third party SSD boot time as i am not aware if mac users with Apple SSD drives are experiencing the same.
