Lots of little things..like oddities....
I have just finished installing Leopard on three machines:
2.4Ghz C2D iMac (2gig of ram)
2.0ghz C2D MacBook (1 gig of ram)
2.0Ghz iMac G5 (2 gig of ram)
First, lets talk about the G5:
Of the three, this was the slowest install. Took an hour and a half.
I planned on selling it after I could load leopard on it. It had a fresh install of 10.4 after I wiped the drive.
Boot up time:
10.4 (fresh install): 48.04 seconds
10.5: 54.32 seconds
A little longer boot up, but not by much. Everything about Finder is definitely snappier. Coverflow takes about 4 seconds to load all the icons in the application folder the first time you open it from startup. After that, all the icons are always ready to go. Quick View seems fast. Safari is way faster. iLife applications all seem to work fine, but no noticeable difference using them. FRONT ROW IS INSTALLED!! I have the revision B iMac and Front Row was only available if I hacked my mac (which I didn't) but now it is there and ready to go!
If there is anything else someone wants me to test, let me know. I'll do pretty much whatever to this mac since I can just wipe the drive clean again when I throw it up on ebay next week.
My opinion: Well worth the update! The only thing noticeably slower than my C2S 2.4Ghz iMac was coverflow. It takes a second or two longer to display all the images, but it is pretty snappy after that.
2.0Ghz C2D MacBook:
This was the fastest and easiest install. Just under an hour to complete, no time machine back up. (this is used as more of an internet appliance at my house--everything important is saved to the desktop).
Everything worked after a really long reboot (be prepared, each machine hung at the desktop wallpaper and mouse for what seemed like an eternity)
Nothing special about the install at all. Went very smooth, all hands off after the initial couple mouse clicks.
iMac 2.4Ghz C2D
Time Machine: needs a fully erased hard drive. I didn't realize this so I had some files to move around. I manually back up everything before leopard, so I had to wait a while for 60Gig of images to get moved to another external hard drive.
hmmm...923,000 files? Didn't realize I had so much stuff. Is this normal? I have about 50,000 images. One thing I noticed, the number of 923,000+images doesn't go down. When I copy files, they usually count down until they are all copied. Time Machine sticks to the original number.
Spotlight took forever to index everything, and the time changed from 17 hours to complete, to 17 minutes, and then back to 17 hours again. Up and down it went, but finished in about 2 hours.
Safari did the strangest thing: After upgrading, EVERY bookmark I ever deleted re-appeared in my book marks bar! I had to go through and delete all the old junk. The MacBook did not do this, just the iMac. Weird.
Quick View: the quick view icon is not in the finder window by default. This threw me for a loop since the tour video showed it on the top. I was losing my mind trying to find it too. I've never really messed with finder windows in the past (I've been a mac user for 3 years), and I didn't know you could right click on it and add icons.
Overall impressions:
I love OSX10.5! Coverflow and Quickview are awesome! I love stacks, but I wish I could keep the icon to always appear as a folder rather than the first document or application listed. Safari is wicked fast. I can barely make out the blue dots on the Dock, I want my arrows back. Preview looks great, and is much faster than before. I'm extremely happy with the upgrade.
