Is it just me, or does ML have a much smaller footprint than Lion? I'll have to check against the mirror of my drive, but I feel like I reclaimed 10GB or so with the upgrade today.
Did this smaller footprint relate at all to RAM or just HD space?
Hard drive space. I have my system and apps installed on a 60GB OWC SDD. Roughly speaking (again, best guess based on my recollection, but I can confirm against the CCC clone I have at home in case of emergency), I had about 30 GB free under Lion. I now have about 40 GB free, with part of the used space taken up by the ML upgrade downloader so I can burn an emergency USB drive at some point.
I don't think I've ever seen an OS upgrade that reduces the space used...
I noticed that same 10GB bump in HD space switching from Leopard to Snow leopard.
I just wish I could find out if ML takes as big a bite out memory as Lion did. I'm maxed out at only 4GB and Lion takes 2GB just to run without any apps launched.
Leopard to sl was a huge weight reduction.I don't think I've ever seen an OS upgrade that reduces the space used...
I haven't checked RAM usage. I've got an 8GB system (early 2011 15" MBP), and I believe I could take it to 16GB if necessary, so it's a non-issue to me.
