boot very slow after installed Yosemite

HAve you checked your startup items ? My new Mac Pro takes abot 5 seconds to start. I have only 2 startup items.

MBP 2013 Retina with SSD and external Thunderbolt display.

Super slow boot, very slow mouse move.

Followed the suggestions - repair permissions etc.

For me it was a 4 Port Belkin USB Hub.

As soon as I connected it to the laptop it was extremely sluggish (be it connected directly to the laptop or connected to the thunderbolt display).

With the USB Hub removed the laptop boots extremely fast albeit a tad slower to log in.

I finally went to the apple store since I am still under warranty. After disabling firevault I was told that would fix the problem. It did not and now I am being told that there is nothing wrong with my computer. It is "older" (2011) and may stay slower because of that. It may also happen that bug fixes will help us all. My battery now has half the staying power but apparently that too is not uncommon and will not necessarily be fixed by putting in a new battery. In other words I may just have to live with above annoyances. Thank-you everyone who responded. Hope this helps.

My system took over 2 minutes to get past the 'progress bar'.

Yesterday it took about 15 seconds. (If you don't have it, get Etrecheck... free at .... )

I have a late 2012 mac mini and I upgraded (fresh install) of yosemite, boot time varied between 44s and 74s compared to mavericks which boots in approx 25s. I compared the two with dual boot and have decided to go back to Mavericks until a fix is sorted. I am uncertain why there is such a variance in boot times. NB I am also running win 7 ultimate with boot camp on the same drive, but Mavericks still boots very rapidly.

To date I have tried:

* Remove all startup items in Preferences

* Did SMC Reset

* Repaired Disk Permissions

* Reset PRAM

Nothing helped. Nothing worked. EntreCheck shows nothing wrong.

Come on Apple. Earn your reputation for excellence and uncompromising quality in released produce.

Or, is Yosemite another Maps product?

Thanks! This solution works for me. Now my macbook (mid-2012 with SSD) boots with-in 12s (Before it takes longer 30s)

OK. I got Yosemite to speed up; about 10 seconds once I get the progress bar.

I found that if I have my HP Photosmart 7225 turned *OFF*, Yosemite starts as expected. If my HP is *on*, it takes a minute and a half.

So, I went to the HP web site. They state that if my driver was OK with Mavericks (it was ok), then it should be ok with Yosemite. I reinstalled it anyway. No change.

Then I turned off, at the printer, the wireless connection to my network. No change.

Now, I just turn off my printer at the end of the day. Start OSX in the morning, THEN turn on the printer. I suspect that will be the process until Apple/HP can figure out what the *real* problem is.

Hope this helps..

I have the same problem look here : https://www.youtube.com/watch?v=2J1a6iMIpVM

I finally got mine to start in < 10 seconds.

It was really an accident. An Apple tech put a program on my system to gather log files. That zip file was automatically named 'RonPrinterPDF.zip'. Huh?

So I started focusing on my printer. (See prior post).

Acting on a tip from another post I:

Went to Preferences / Printers and right clicked on my printer.

Then I selected 'Reset Printers'.

(This removed all printers)

Then I clicked on the + sign below to add back my printer.

Ba boom. No more lag time.....

Hope this helps.

hey. i think i found a solution but it does require backing up all your work. the problem is is that you may have installed mavericks on mountain lion, and Yosemite on mavericks, 3 layers of OS X does cause lag, doing a clean install should solve this problem for you You need to do a clean install by downloading a fresh copy of Yosemite on a (minimum 8gb) usb drive and then delete everything and start from scratch. click here to get a step by step: http://osxdaily.com/2014/10/18/clean-install-os-x-yosemite/

😕

I have MacBook Pro (13, 2012) and after I installed yosemite beyond the slow start (on the progress bar), my mac has slowed in general, need to click on things give two clicks and the top menu bar is black.

I tried everything here and nothing worked.
