Startup slower that it used to be...Jargon translator needed

Question

can anyone decipher this console jargon and tell me if there are any issues during startup.
My mbp seems to be starting up a lot slower that it used to be.
and any suggestions of how to freshen up my speedy startup would be great.

Answer 1

Maybe because you've installed Quicksilver, which is responsible for all that stuff you posted. The computer will start slower with each bit of software you install and launch at startup. If you want quick startups remove all the third-party startup items you have installed - like Quicksilver - or accept the slower startup for the features you desire.
In addition to the above and any other third-party software that launches during startup you can try cleaning caches and repairing the drive and permissions:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
To clean caches download a utility such as Tinkertool System or Snow Leopard Cache Cleaner to remove all system, user, and font caches (a restart is required immediately afterwards.)
