I don't know if all your questions were answered, or if you want more. And I apologize in advance if the other half of the unread responses already stated my issues. First, the MacBook Pro trackpad preference "Ignore accidental trackpad input" does not appear to work. And "Ignore trackpad when mouse is attached" has disappeared under mouse preferences. These are likely related. A bug has been filed. No response, AT ALL except the robot thank you email. I gained 15GB of disk space. I don't know what was lost or given up. Everything appears to be intact. I went from 12GB free (of a 120G drive) up to 28G free. Xcode 3.2.1 (needed for 64 bit development and iPhone OS3) has major issues related to documentation. Everyone I know at Apple HQ thinks it's a POS. That's where they send the newbies in base development because the clientele are all intelligent enough to find workarounds for all of the undocumented features the newbies have installed. But it is stable. No crashes or the equivalent of the blue screen of death.

Finder in Leopard and earlier use the traditional computer notation where KB/MB/GB are measured in powers of two, while Finder in Snow Leopard has switched to powers of ten. For capacities measured in gigabytes, this gives an apparaent increase of 7% in all numbers relating to disk capacity, free space and file size. Therefore your "12 GB" free (under Leopard) would be displayed as almost "13 GB" in Snow Leopard, and the drive capacity would have increased from about "112 GB" to "120 GB". A moderate chunk of the saving is due to no longer having to include PowerPC code in many files in the system, since PowerPC Macs can't run Snow Leopard. (There is still a lot of PowerPC code there to support PowerPC applications running in Rosetta.) A large chunk of the saving is due to using a compression mechanism for many files in the system. The rest of the saving is due to not installing all the printer drivers by default, just those you are actually using. Net result is a lot of disk space saved with no loss of functionality. -- David Empson dempson(a)actrix.gen.nz

I noticed that! I thought it was me and I just hadn't figured out how to turn it off.

Not a significant one. Do a Google search for "HFS+ File Compression" to find some background. It was described in detail in an Ars Technica review of Snow Leopard, and the relevant bit is duplicated here: <http://blog.fosketts.net/2009/09/11/bizarre-hfs-tricks-in-mac-os-x-10-6 -snow-leopard/> In short, the compression is only used for read-only system files, and the files in question are likely to be read infrequently (e.g. when loading an application or library), so the impact is relatively low. The CPU is fast enough that it probably takes less time to decompress the data than it would to read a larger file from the hard drive. Net result is more CPU activity and probably neutral for time required to load the file, but a significant space saving. If the computer has a solid state disk instead of a hard disk, the compression may be a performance disadvantage, but the space saving is even more important because of relatively small capacities for solid state disks. -- David Empson dempson(a)actrix.gen.nz
