In Lion Apple introduced full-screen apps that take over the screen, hiding the Dock in the process. But don't worry, it's still there, and it doesn't take any magic commands to get to it. Gestures rule in Lion.
To get to the Dock from a fullscreen app, just move the pointer all the way to the edge where the Dock is pinned, then swipe or move the mouse in the same direction again, as if you were trying to move beyond the edge. The Dock pops right up, with no keyboard commands needed.
This is probably the best solution for full-screen apps where you may frequently need to move the pointer quickly to the edge of the screen where the main buttons are likely to be. If it just popped up the Dock when you move the pointer to the edge (as with 'Hide Automatically), it would be a source of frustration.
[crarko adds: It took me a few tries to get this to work. As with many gestures, it requires a pretty light and precise touch. Otherwise you'll just wind up scrolling the window in your fullscreen application (like Safari, where I tried this).]
Lion by default opens the Dashboard as its own space, which means you can't see the desktop 'through' it like you could in 10.6. You can return the Dashboard to its former transparent splendor by telling Mission Control to not open the Dashboard as a space.
To return the Dashboard to its pre-Lion behavior:
Open System Preferences.
Click the Mission Control panel.
Un-select the 'Show dashboard as a space' check box.
Close the System Preferences.
Not only will the Dashboard return to displaying as an overlay above the desk, but as a bonus, you will have back the cool 'ripple' effect when adding new widgets.
[crarko adds: This is one of those things that's only obvious if you've looked for it. I don't use Dashboard much, but if you do, and liked the old way better, here you go.]
Although this is not really an easy way of doing this, I've decided to share this hint, because the impossibility to remove anything from Launchpad was really annoying me.
Use this hint at your own risk! Be sure to have some kind of backup available.
Using Launchpad, create a group of items named 'Trash' and fill it with the shortcuts you're wishing to remove.
Unhide your 'library folder' (See this previous hint, or use your favorite method).
Backup your Launchpad database located in ~/Library/Application Support/Dock.
Download any sqllite query editor (Navicat Lite is very good and free).
Open the Launchpad database with Navicat.
Run the following query:
where exists (
items as i inner join
groups on i.parent_id=groups.item_id
groups.title like 'Trash' and
items.rowid = i.rowid
The database is taking care of data consistency via triggers (triggers will remove images caches and reorder items).
The good point is that the (now empty) 'Trash' group will remain.
[crarko adds: I haven't tested this one. As mentioned in the hint, please be careful and have a backup handy before trying this. I have to say, Launchpad is one of those features I'm kind of 'meh' over. I have no interest in reorganizing the thousand-plus applications I've got into folders again. Maybe on a new machine.]
Having very many applications, my default Launchpad was a complete mess with little options for cleaning it up. Not one of my Apps had an X to delete it with the Option Key down. It would have taken hours to clean up.
You can not move Apps to folders or the Desktop from the /Applications folder, but you can move them to the Trash. So I emptied my Trash, and then moved most of my Apps to the Trash.
Then I created a folder called Applications2 and moved them all out of the Trash to there. That was a big step to clean up the Launchpad.
I then added some more Apps from the new folder but dropping them on the Launchpad, but later I found out that I could not delete those from the Launchpad either. The workaround there, is to drag them to the original Applications folder, then to the Trash, then back to Applications2. Go figure!
[crarko adds: As with today's other Launchpad hint, one gets this feeling the feature is best used on a new, fairly minimalist system. The iOS metaphor is fine for a hundred or so applications, but gets really tedious with substantially more than that, unless you've built it up that way from the beginning.]
In the release version of Mac OS X 10.7, there is a bug that prevents secondary click working with two-finger click on the Macbook Pro 4,1. The only way to right-click is using Control+click.
To enable right-click using two-finger click, run the following in Terminal:
This hint shows how to create your own Recovery HD (Disc or Flash Drive).
Mac OS X Lion includes a hidden Recovery HD. This is a small partition about 650MB in size which you can boot from by pressing down Option at startup. It includes a variety of utilities which can help you troubleshoot a Mac.
It can be very handy to have a bootable copy of your own on some other media incase you need to troubleshoot a Mac with a bad drive, or something has happened to the recovery partition, unlikely but possible.
To do this we need to find and mount the hidden disk image with the Installer.
This is done to be able to see hidden files, including the disk image used to create the recovery disk.
Restart Finder via your preferred method. (Force Quitting, killall in Terminal, or logging out all work the same.)
In Finder find where you saved your Mac OS X Lion Installer to (probably your /Applications folder) and right click and select 'Show Contents.'
Go into the Contents/SharedSupport folder and open InstallESD.dmg
Now find BaseSystem.dmg and mount (open) it. The file is a 'hidden file' and will be slightly greyed out.
Now you need at least 1.1GB of free space on a flash drive or DVD. You can use either a 2GB drive, or partition your larger one, but I recommend keeping the Recovery partition free from your normal files that go on a flash drive. Make sure this partition is formatted as Mac OS X Extended Journaled. (You'll probably want to have the rest of your flash drive formatted as FAT if you work in a multi-platform environment.)
Copy over the entire contents of BaseSystem.dmg to your flash drive however you like. You can use Restore in Disk Utility, the Terminal, or your favorite cloning app. Make sure that you get all the invisible files that are there if you're copying over everything manually. Or if you're burning a disk, make sure you're burning the contents of the disk image, and not just the image itself (it won't be bootable that way).
Restart the Mac holding down Option, and test the drive to see if it worked. If you named your flash drive Recovery HD then it will have a USB drive icon when it starts up compared to the Recovery HD with a hard drive icon, which is that part that is on your actual startup drive, or you can name it anything you like.
Now, turn off the invisible file viewing in Finder if you want to. (There's no danger to keeping it on all the time as long as you know which files you can and can't mess with.) To do this go back into Terminal and type:
