I have seen so much response about the Mountain Lion update slowing down computers.  I am updating from Mac OS x 10.6.8.  What can I do to ensure the upgrade will go fine?  Do I unplug my external hard drive before installing, or keep it plugged in?

 

Also, I have the 08 version of iWork. Will this cause problems for the update?  Can I update this AFTER I update the processor?

There's no reason to think that Mountain Lion will slow down your Mac. Just make a backup of your data before upgrading with Time Machine > http://support.apple.com/kb/HT1427

 

Also, check that your apps are compatible > http://www.roaringapps.com Upgrade them to a compatible version or delete them before upgrading.

 

The external drive won't make the OS X Mountain Lion installer fail, but it's better to unplug it during the upgrade.

 

iWork '08 is compatible with Mountain Lion. iWork '09 includes OS X Mountain Lion features and can be purchased at the Mac App Store.

 

To upgrade to OS X Mountain Lion, I recommend at least 4 GB of RAM. You can check how much memory you have in Apple menu > About this Mac

I recommend you to install 4 or 8 GB of RAM at least. You can buy more RAM at OWC or Crucial > http://www.macsales.com Depending on the amount of memory you install, it will cost more or less

    What if I only have 2 GB of RAM?  Do I need to take it in to add?  How much will this cost?
