    Hi guys,

    I installed 10.10.3 on my iMac a couple hours ago and I was presented with a gray screen and my mouse. I restarted a couple times and nothing. I tried to re-install using system restore and same thing. Does anyone have any ideas!? :-(

    Yep,

    Got a very similar problem here too. Normally I switch my MacBook on, Apple logo appears, then login screen.

    Since 10.10.3 it takes at least 30-40 seconds before the Apple logo appears. It just sits with a grey screen.

    Are you guys using the Trim Enabler app for a non OEM SSD? If so, did you turn it off before updating?

    Are you eventually able to login and use the PC or does it sit there with the gray screen forever?

    ----------

    I never installed a Trim Enabler app, so this can't be it.

    No I'm not using Trim Enabler either.

    I can eventually sign in after the Mac has sat on the grey screen for 30-40 seconds.

    I'm using TE and it wouldn't let me turn it off before the update. It said there was no backup file on the drive anymore. I ended up leaving TE turned on and just did the update. It went without a problem but on rebooting TE did give the notification to turn it on again and reboot (which I of course did and it worked as desired).

    Sorry I have no help for your issue. Just putting out the information for consideration.

    Lucky you... I've waited almost 15 minutes and nothing but gray. If I hit keys I get the "BUM" sounds effect the Mac makes when it doesn't like something you do, but nothing else other than a mouse pointer. So weird. I am trying to reformat and reinstall, again! :-(

    Not really, I've had a similar problem when going from 10.8 to 10.5. The solution was a PRAM reset. I've also had similar issues when adding new PCIe devices, the solution was a PRAM reset.
