This I thought sounded awesome as I am constantly looking for more space on my internal hard drive.
Pre install I had 21.47 gigs available. After install it had jumped to 35.28
That's almost 14 gigs! Double the oft-mentioned amount.
Did anyone else see hard drive increases of this, or more even, amount?
Check out this thread
from post six onwards. Also read this
Apple has changed they way they calculate file sizes and disk space, so now when they say
GB, they mean
GB (1,000,000,000 Bytes), whereas before they said GB but they were actually GiB
What this means is that whilst Apple have reduced the amount of space consumed by the OS, the "new maths" also makes it look
like you've got more free space than before. For example, get an external disk and see how much space 10.5 says is free, then take the disk and mount it in 10.6. The data on the disk will not have changed in any way, but Snow Leopard will report more GB space free. That's because 10.5 is wrong (as are all previous versions of Mac OS and all versions of Windows and many distros of Linux), and 10.6 is right.
