iMac Very Slow Boot- 2mins somedays

Hello all,

I am having a bit of a dilemma lately. A couple months back I updated to OS X Yosemite on our Late 2013 iMac, with a 2.9Ghz Quad-core Intel i5 processor and 8GB of RAM. The OS itself runs just fine and dandy once it is entirely booted up, but the boot up process ranges from 1min-2mins somedays. It just sits on that progress bar, and loads slow as molasses.

I have tried every trick in the book (from what I've Googled):

Reset the PRAM/SMC
Disk Permission Verify/Repair - it found issues and repaired them, still super slow.
Disk Verification/Repair - nothing came up
Deleted several thousand files(personal files, not system files), and emptied the recycling bin (it was no where near full...its a 1TB HD)
I read some article somewhere on here about resetting the "Printing system", and it worked for many people, but did no justice for me.
I have also checked my startup items, there are none.

I am not experiencing any Wifi issues, or other Yosemite bugs that I have noticed.

Anyone got any idea what could be the problem? The last thing I want to do is reset this system entirely. Its a pain, and if I am to do that, I will be downgrading back to Mavericks for fear its going to still be a problem upon a restore of Yosemite.

Thanks for your help ya'll!

iMac, OS X Yosemite (10.10.1), i5 Quad-core, 8GB ram, 1TB HD

I hope you didn't just randomly and willy nilly deleted files from all over your Mac.

If you don't know what you are doing, you can do irreparable OS X system damage to your Mac.

Have you look at how many apps that maybe launching in the background at startup/login?

Add or remove automatic items

Choose Apple menu > System Preferences, then click Users & Groups.

Select your user account, then click Login Items.

Do one of the following:

Click Add ➕ below the list on the right, select an app, document, folder, or disk, then click Add.

If you don’t want an item’s windows to be visible after login, select Hide. (Hide does not apply to servers, which always appear in the Finder after login.)

Select the name of the item you want to prevent from opening automatically, then click Delete ➖ below the list on the right.

No no, I didn't delete system files, I meant my personal work files.. I have checked how many apps are in the background I didn't have anything other than iTunes, but I removed it and it still had no effect on the boot up time.

Also, even though you may have installed and downloaded OS X 10.9 Mavericks previously, many users have reported that they can no longer redownload it as it appears that Apple has removed it for the Mac App Store servers.

So, if you didn't create a cloned backup of your previous OS X 10.9 system and data, reverting back to OS X 10.9 Mavericks may not be possible.

The only other option maybe to purchase a special download code, from the main Apple store website, for downloading OS X 10.8 Mountain Lion, which is still available from the Mac App Store.

Good Luck!

I think we should start to see how your system is configured, please post an EtreCheck report of the computer and we can look for obvious issues.

Please take each of the following steps that you haven't already tried. Test after each one. Back up all data before making any changes.

1. Set the default startup disk.

2. Disconnect all wired peripherals except those needed to start up. If there's no change, reconnect them

3. Reset the printing system.

Late 2013 iMac

If you have Apple Care, give them a call. Let Apple deal w/your problems while you are under warranty. It's what you paid them to do. 😉

OS X Yosemite (10.10.1)

Use Software Update/App Store to update your OS to OS 10.10.3. Or install the combo update. Also, update everything SU/AS has to offer for your computer. When done, repair permissions and restart your computer.
