There is a thread listed in the Mac Guides header of this forum about freeing up drive space. Complete Steps to Perform a Clean OS X Reinstall on Your MacBook Air However, it is outdated as it is based on a 2008 thread and doesn't cover the process regarding OS X 10.7 Lion at all, of which there is not even a remote disc to use. GGJstudios and I began discussing it in a thread I prematurely asked to be deleted. There are programs like Monolingual, and I've also used XSlimmer in the past though I'm not sure since that just attacks Binary/Universal duplicity, if there is any real use for it here. I'm also not sure if Monolingual just takes out the ability to boot to additional languages or if it also addresses the additional fonts that may be unnecessary. What I'd like to know is if you can do a clean install of Lion on a MBA from the recovery partition and eliminate items from the install to slim it down and save space like you could in Leopard and Snow Leopard. And if it is worth it. In those builds the savings was easily 6-8 GB. So for good reason on a space limited (128 GB) MBA, I'd like to free up what space I can.
