I've recently upgraded to a Mac Pro 4,1 from a Power Mac G4, and to Mac OS X 10.6.8 from 10.4.11 in the process. There are a few little ways in which Snow Leopard behaves differently to Tiger, and I'm wondering if (for each item on the list below) anyone has any suggestions on how I can make things behave as I'd like, rather than as they do. While I'm at it, I've included a couple of things that never behaved as I'd like in Tiger either, but which may also be alterable. I'd prefer, if possible, solutions that result from simple changes in settings, or perhaps "sudo" commands entered into Terminal, rather than having to install third party software. Also, I'd appreciate those that choose to reply refrain from suggesting I upgrade to Lion or Mountain Lion. These aren't options I can consider at the moment. 1. After the Mac has booted and reaches the Login screen, the desktop picture is the "aurora" image. Once I log in, my chosen desktop image appears. Is there any way to change the pre-login "aurora" image to something of my choosing? 2. In the Finder, clicking Go -> Recent Folders gives the 10 most recently opened folders. Is there a way to change this number? 3. In the Finder, folders on the desktop often don't deselect the way they always did in Tiger. For example, if I double click a folder to open it, the folder's icon highlights. The folder often doesn't deselect / unhighlight though when I then click on the desktop or elsewhere. It often takes 2 or 3 additional clicks for the icon to deselect. Is this a known bug, and can it be fixed? 4. In the Finder, under Preferences, I have "Always open folders in a new window" checked, as I prefer. Often though, I like to hold down the "alt" key when double clicking on a folder to open it, so that the enclosing folder closes at the same time as the folder I'm double clicking on opens, thereby overriding the preference I've set. In Tiger, the newly opening folder would always open at its previously set size & position. In Snow Leopard though, using the "alt" key causes the newly opening folder to open at the size & position of its enclosing folder instead, not at its previously set size & position. Worse, the folder then seems to "remember" this incorrect size & position which it takes from its enclosing folder, wiping out its previous (correct) size & position. Is there any way to make things behave like they did in Tiger? 5. In Safari (version 4.1.3) under Tiger, the Command-` keyboard shortcut (that's Command and the key to the left of the "z" key) cycles through each open Safari window in turn, before returning to the original window. However in Safari (version 5.1.7) on Snow Leopard this keyboard shortcut seems to work very erratically. For example if I have, say, 8 windows open, the shortcut might only rotate through the 2 or 3 frontmost windows over & over again, rather than through all 8 in order. It might take 5 or 6 cycles before the rest of the windows appear at the front of the stack. Is this a known bug, and can it be fixed? Many thanks in advance for any input anyone has.
