Just finished upgrading our three Intel Macs to Mac OS X 10.6 Snow Leopard; the upgrade, as promised, has generated some real savings in disk space: the two iMacs got nearly an extra 12 gigabytes, my new MacBook Pro an extra eight. (Figuring out the difference is complicated by the fact that Snow Leopard uses a different definition of gigabyte than Leopard does — 1,000 megabytes instead of 1,024 — so I calculated this from the raw byte totals.)

The upgrade hasn’t been without a few glitches: some settings were mysteriously changed, and MobileMe syncs got a little screwy after the first computer was upgraded: for example, it wanted to make changes to my Keychain, which set off my alarms since I’d read this entry, so I disabled MobileMe keychain syncing for the time being. (Don’t mess with my passwords, computers.) But only minor stuff so far.
