Q: MAC start-up very slow

What do you have in startup items and how much RAM does the computer have installed? Also what is the capacity of your internal HD and  how much free space does it have?

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!

The boot process has several stages. Please see this support article and determine at which stage the problem happens.

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?
