Tiger

I pre-ordered my copy, having seen a friend's developer connection installs go well over the last few months, and liking what I saw in terms of features.

I thought I'd try an upgrade first, rather than clean install, play around for a bit, then do a clean install once I'd got to grips with it.

Well, the install went very smoothly, and everything seemed ok when I rebooted, but very slow. Turns out the spotlight indexer was running away, trying to index the 20 or so gigs that were on my drive.

Until... I started trying to use Mail.app. It kept hanging - it would list my mailboxes, and show me a list of messages in my mailbox, but it would just sit there spinning. tcpdump showed IMAP traffic, but nothing very interesting. So, I tried rlogging into one of our SunRay servers, and mutt-ing from there. Absolutely fine. Tried mutt from the Mac - locks up solid. tcpdump -vv port 143 shows lots of traffic, but with all tcp bad cksum errors. Weird. All other traffic looks fine.

At this point I suspected either something firewally or maybe the fact that I had Cisco VPN client, so disabled/removed both of them. And rebooted. Same problem. Fiddled some more, rebooted some more. Nothing

So, a clean install later, and everything's working as I expected.

Although... Spotlight is cool, but a real pig when it decides to index something (like the file contents of my iPod) at random times. It absolutely slaughters your machine.

One of the most significant improvements for me is the addition of a slideshow to Finder, coupled with the fact that image previews seem to build significantly quicker (thumbnails, I mean).

More rants or praise when I've played some more!
