Archive/Install here. Lets see, had to uninstall/re-install Parallels, had Mail crash one time, but other than that everything else has worked great.
 
Did an upgrade on 2 machines: A MBP and a 12" PB. Everything seems hunky dory, apart from some issues with the X11 implementation (which will hopefully be fixed by Apple soon). As usual I have no issues running an "upgrade" as opposed to a clean install. In fact the PB has been upgraded from Jaguar->Panther->Tiger->Leopard.
 
My Leopard Purrs

I waited a day after I got mine delivered to me yesterday, just to read on here about potential issues (and so I could make sure I had up to date backups of my docs). After installing it, I didn't have a single issue! I'm a new user of Mac, as of September, and I'm never going back to that OTHER system!
 
Haven't bought Leopard yet but I plan on doing an upgrade on my Core Duo MBP.

Does doing an upgrade still preserve "teh snappy"? I know it's not like a Windows upgrade where everything slows down because it replaces files wrong or whatever.

I'd do archive and install but I simply have to many programs installed to go hunting them down and reinstalling
 
Installed on my mom's Macbook with no problems and I'm in the process of installing it on my Macbook Pro. So far no issues, but I thought it may have gotten stuck at one point. Turns out it was just taking a really long time.
 
i have to ask becuase the seemingly blatant bugs on this release makes it seem like it is not ready for prime time despite being released late.

anyone?

I have so many, I don't where to start...
I hate leopard. i'm reverting back to Tiger. Walt Mossberg was right.
'Leopard isn’t a must-have for current Mac owners, but it adds a lot of value. "
 
I've had none and I did an upgrade install. My computer isn't that old and I haven't really overworked Leopard, but still no issues.
 
I did an upgrade install from 10.4.10. and I have no problems at all. The upgrade went smooth and everything just works. Time Machine is very impressive.
 
Other than Photo Booth being quirky on first boot, a reboot later I was good. Indexing finished and Safari is smooth as silk and the whole system seems to have extra spunk over Tiger. I like it a lot! So I am not having leopard issues at all really.

Note: I had one app that runs in Rosetta only, but it sucked in Tiger too, so its just poor coding, not really Leopard's fault. I never use it anyhow, so I got rid of it.
 
No issues just joy

Was forced into a clean install on my ALiMac, that was the only issue. Then did an Update on my MBP which has a BootCamp partition; the install took a while, ok a good while; but all is well and working speedily. No more freeze ups on the iMac by the way.
 
No problems

Installed on 2 ibooks with dead cd drives via firewire.
1g and 1.33 12 inch models and NO problems installing at all.
Was relatively quick for being older systems. 2 hours.
Have tried a few things in the new OS and everything seems great.
Have not yet tried TM on these as I don't have an external drive.
Will post back when I test it.

BTW. This was a clean install... the drives had to be wiped as they were from some ebay seller that did not have a clue about the Apple OS and they had 3 partitions on the tiny 40 gig hds.

Will try on my Powerbook later... glad I saw some of the posts about Unsanity product problems. Got to do some cleaning before hand.

:)
 
no showstoppers yet

Clean install on a zeroed-out 1st gen macbook. Safari seems to hang up on me a bit but Firefox 2.0.0.8 works just fine. Exercised most of the system settings and haven't noticed any issues. No finder issues, no hardware panics of any kind. My Cisco VPN works. Everything seems faster. My MSword started up with the wrong localization for some reason, but it works. Tried bootcamp and installed ubuntu 7.10 and -that- worked, although ubuntu kernel panicked after install and (i assume) during the restart, it hasn't done anything wierd since then after multiple restarts. Haven't tried any Rogue Amoeba or Ableton or Serato yet. Me stoked.
 
Everytime I restart my Mac now in Leopard it starts with a Globe thats flashing in the middle of the screen for a min or 2 or so. After that it goes back to the normal screen with the Apple logo. Anyone know what this is ?
 
*1 for zero issues*

aside from the normal 1.0 bugs (slow/choppy transitions/effects, minor hangs etc.) I've been running 100% smoothly since install (erase & Install)

*waits patiently for 10.5.1*
 
Battery "upgraded" to 12456mAh

Installed on a Core 2 White iMac and a 15" PowerBook G4 1.67. The powerbook took about an hour to index the drive for spotlight and the battery is claiming I have over 12000mAh to charge. Other than that, no real issues or problems. Both machines are speedy.
