MAC start-up very slow

When I start up my MAC, it takes about 5 minutes to start up. Is there a solution for this problem

iMac, OS X Mountain Lion (10.8.4)

try doing SMC reset, the following article tells how to do this:


http://support.apple.com/kb/HT3964


your startup items can be found in your user library (you access this by opening a finder window then clicking on go from the main menu bar, and choosing computer from the drop down.


open the folder on the mac HD that says library and then look for the folder that says startup items


i would remove anything from this folder that is not absolutely needed.


hopefully this helps! 🙂

My computer is a 27-inch Imac bougt in 2010. It has a 2.8 Ghz intel Core i5 processor, 4 GB 1333 Mhz DDR3 ram and a ATI Radeon HD 5750 1024 MB Videocard. The harddisk is a 1TB SATA harddrive. I cannot find the startup items, because I dont know where to look for it.


In de system overvieuw>software>Startup items says "No information found

To locate startup items go to:


System Preferences-Users & Groups-select the user on the left then click the login items tab.


Also 4GB of RAM is not that much these days. I would strongly recommend you use Activity Monitor to see if there are any applications taking a large percentage of CPU and see if 4GB is enough for your needs. Apple explains how to use AM in Activity Monitor to read System Memory and determine how much RAM is being used

Mine is really slow in Kernal, how do I fix this?


Mac Book Pro
OS X 10.9

3.06 GHz Intel Core 2 Duo
8 GB 1067 MHz DDR3

NVIDIA GeForce 9600M GT 512 MB

500 Gb HD 320 Available


I thought it might be the fact that my HD had less than 15 Gb left free, I then bought an external HD and moved things I didnt imediately need on to that, it's still slow.


Thank you

I have the same problem, and my iMac is very similar age/spec. It seems to have got worse since I installed Mavericks (plus MS Office 2011). I've checked the startup items folder and there's nothing in it. I get the grey screen for a couple of minutes, then another couple of minutes for all the icons to appear. Just like the bad old days when I had a PC!

Can anybody offer help?

well i have 16 GB Ram i7 CPU on Mac Mini, with 1 TB drive (400GB used)

it takes about 6 minutes to reach desktop after watching a slow loading bar for about 5 minutes, then desktop icons take about 4 minutes to load

ever since Mavericks

16GB Raam with an i7 should be able to load it in 5 seconds!

When i first bought the device it loaded in about 30 seconds all stages

all Macs did. It used to be an advert showing how fast a Mac loads c ompared to Winfows

Now windows could get their own back by making an identical ad, but now showing how Mac is much slower to boot than modern windows 10 devices.

All my friends also say that their Macs now boot ten times more slowly than before. But my Mac Mini definitelyt loads a lot slower than my Macbook Air.. iMac and Mac Mini both very slow to Load.

To be honest, if i were to pinpoint when my macs started to have problems, its precisely when Apple moved from iClod to iCloud Drive.. exactly same time

Interesting assumptions however they are all incorrect. My 2011 iMac has worked perfectly since day one, it has 24GB RAM (I ONLY buy either Crucial direct or OWC), other RAM has proven problematic. It also has a SSD installed as the startup drive, this reduced startup and shutdown from about 30 seconds to <10 seconds. I have NEVER installed any cleaning, antivirus or ANY other third party maintenance apps because they are proven to modify and thus harm Mac OS. I also don't have adware installed and don't use a torrent to download anything because it is risky.


In every situation that I have seen where users are complaining of slow startup and shutdown, it is either hardware (failing HD, RAM related) or the user has installed some type of software mentioned above.
