LONG POST BUT HOPEFULLY HELPFUL:
First something I personally don't like is when people post something like "hope it fixes..." or something like "yay". Why don't you try out the update and tell us what it fixes or what makes you go yay. Also beyond the first 2 accounts of how big the update is do we really need to hear more. Not like the size changes anything or determines if we are going to install it or not. Not trying to be mean to anyone or sound grumpy just stating my opinion.
Anyway hope this helps other users. Installed well (combo update). I didn't have many problems on 10.6.1 but most of them are still there with 10.6.2. Only weird thing was it reset my sound preferences in system preferences:
PROBLEMS I'M STILL HAVING
In icon view in Finder shift clicking does not select a range but acts like command clicking does.
In iCal when you perform the goto date and then type in the date and hit enter the enter command is not recorded but the mouse needs to click on the OK button.
Also entering a date in the goto date can jump around and give you a strange date if you make a typo along the way.
If you go to a date in ical that is a saturday in week view it will take you to the next day (sunday).
In iCal when using the inspector if you change the title of an event then change how often it repeats the title and/or the repeat dont take and you have to redo your steps or it will lock up and ical needs a relaunch.
In iCal when you search for something then you change its repeating pattern you need to delete your search terms and research for it.
In Mail when I right click on an email address and copy address it not only copies the address but also the name associated with the address and the address is in < > which makes it hard to use unless I delete out the name and the brackets.
I have a list of first names in Pages. I make a PDF using the built in print to PDF feature then open the PDF and select the list (each one separated by a return) and copy and paste into a spreadsheet. The returns are missing and seems to pick a predetermined length per cell before it wraps to a cell lower. This was fine in 10.5 but not now in 10.6.
When opening a folder from a stack by Command Clicking on it the window size and location isnt memorized from the last time but rather defaults to another window size and location.
In Preview Annotation Text when clicking for cursor (not dragging a box) it truncates the last letter or word unless manually resize the auto box created
In Safari when I have multiple tabs open and I click on a link that takes me to the iTunes store when I return to Safari it is not on the tab where the Safari link is but rather on the last opened tab of Safari or it will take me to a Tab saying the iTunes store is loading.
In the help menu in Safari I enter dashboard and then hover over the Open in Dashboard... and it sometimes selects Mail Contents of This Page instead of the correct menu item.
THINGS THAT WERE WRONG IN 10.6.1 BUT I HAVEN'T BEEN ABLE TO RECREATE YET (SO MAYBE FIXED):
After Software update performs and then says successful (or restart now option) going to a different space hides the popped up window and Apple-Tabbing back or clicking on Software Update in the dock does not revert back to the space with the window so you need to manually go through each space to find it to take action for Software Update to be happy. - Also with other apps when having a dialogue box up.
Screen sharing without a password try to connect first time says wheres password just clicking connect again makes it go through just fine. Takes 2 tries every time.
Sometimes the trash will look empty even though there are things in it and the option to empty it is grayed out from the dock icon but the finder menu will still work.
iDisk syncing was not going through.
Keyboard and mighty mouse get sluggish. They are the white apple bluetooth ones. Whichever one it is if you turn it off then back on it temporarily fixes the problem.
THINGS THAT 10.6.2 SEEMS TO HAVE FIXED FOR ME:
Mail is hanging on to my drafts more than it should. I use gmail with imap and often but not always when I compose and email message it will save a version of my message in drafts even though I didnt save it and I have completed and sent the message. The complete message shows in my sent box but the other version of the message is saved in drafts.
Annotation text boxes when clicked move the page around a bunch.
YES I HAVE SUBMITTED MY PROBLEMS TO APPLE'S FEEDBACK PAGE AND SUGGEST YOU DO THE SAME.
