More Lion speed tips for Mac OS Lion

Complete instruction to increase Lion speed

Recently I talked to the Apple Care Support for more than an hour – wow, I can just say they have a fabulous support and the Apple Care Protection plan really is no waist of money – although it is pretty expensive. I can call the Apple technics as often as I want and if my computer fails I quickly get help from their technicians. All this is already included for one year and is expanded with the Apple Care Protection Plan to three years from the date you bought your computer.

But that is not what I wanted to tell you today. I phoned the support because my Time Capsule wasn’t finishing the backup. The guy on the phone told me that he would go through some repair processes with me – and it took him over an hour because I never did that to my computer. He highly recommended to do that every half year; although the system cleans up itself there are some areas which need deep cleaning to make your Mac run faster. As I cannot show you all steps with screenshots – please just print out this article. It is not that hard to go through as long as you follow these steps as mentioned.

1. Empty Cache to increase Lion speed

No, I’m not talking about the general browser cache – I’m talking about the folders your computer creates where it saves each and every program you open and each and every file you open. So if that folder grows in size you can imagine that your computer gets slower.

  • Open a Finder window
  • My Macintosh HD is named “My MacBook Pro” so wether you have Macintosh HD there or the name you have chosen. If you don’t see your hard drive you need to turn on the  devices in your sidebar. That’s easy: Go to Finder –> Preferences, click on the Tab “Sidebar” and click under devices on “Hard Disks”.
  • Click on the folder “Library” and locate the folder “Caches”, delete everything included in this folder.Don’t worry – nothing can happen here.
  • Now we empty the second cache folder. Go to the Finder Menubar, locate “Go” and open the menu. While you hover over the menu items just press the ALT key and another entry comes up – “Library”. Click on that one.
  • Again – locate the Caches Folder, go there and delete everything what is in it:
  • Now empty your waist bin. Most probably it will stop and tell you that it cannot delete the one or other file. Just click continue – we care about those in a minute.
  • Once you’ve emptied your waist bin we need to take care of those files who couldn’t be deleted. For that go to Finder –> Secure Empty Trash
    This might take a while – just leave the computer alone but don’t stop the process.
  • Now turn your computer off.

2. Hardware and RAM reset

  • First we reset the hardware: When your computer is off press SHIFT + CTRL + ALT together with the ON BUTTON – keep all pressed for 10 seconds.
  • For RAM reset press R + ALT + CMD + ON BUTTON and jump immediately on P while you still keep R + ALT and CMD pressed. The computer will turn on, make a sound, turn off, – all this three times. Just keep all keys pressed until you hear the sound the third time.

 3. Repairing Disk Permissions to increase Lion Speed

  • Now start your computer and press while pressing the ALT key. You get the choice to start the Recovery HD or to start the hard drive utilities – click on the Recovery HD. What you see now will look similar to this (I say similar because my screenshot is from the Disk Utilities program while the operating system is running). Choose your HD (in my case My Macbook Pro) on the left.
  • Choose your Macintosh HD (or whatever name it has), make sure “First Aid” is chosen and then click first “Repair Disk Permissions” and once it is finished “Repair Disk”
  • The reason why we don’t start the operating system and go to Utillities –> Disk Utilities is that the repairing routine goes deeper into the system without having the operating system started. So it can repair more errors.
  • Once the repair is finished close the window. Now choose from the menu on the top Utilities –> Terminal
  • We are resetting passwords now – no worries, nothing will happen, it just repairs the permissions again. You do not need to enter a new password. Just type in

Now close all windows and restart your computer

4. Now we reset Spotlight

Sometimes the Spotlight structure (the program that indexes your computer) is damaged. This can result in very slow responding time. You do not need to do the step if you feel your Spotlight is working well. On the other hand it won’t damage anything.

Go to System Preferences in your Applications folder:

Click on the Spotlight Icon, then on the tab “Privacy”. Now click on bottom left on the “Plus” Sign – most probably the field is empty.

Now choose your HD – I click on “My MacBook Pro”, then choose


Now it’s a bit odd – your MacBook HD is showing in the list now. Mark it and click on the little minus on the bottom left to remove it again. Confirm if your Mac is “complaining”. Now Spotlight will start indexing your computer again. This might take a good half an hour so no worries. You can observe the process when you look on the little magnifier in the top right – as long as there is a dot in it it is indexing.

Ok, we are done! You have increased the speed of your Mac OS Lion. Let me know if you have any questions in the comments section below.
