Since Apple officially released Mac OS X Lion today I thought it would be nice to have an official thread that contains all Tips & Tricks, rather than having to skim through tons of pages in different threads.

I'll start off with a few of my own:

Disable Resume on a per-app basis

You can disable resume on an per-app basis by locking the folder inside ~/Library/Saved Application State (~ = Home folder) that corresponds with it. You guys might find this useful if you're looking after disabling resume for - let's say - TextEdit only, rather than system-wide.

Make the ~/Library folder visible again

Launch Terminal located in /Applications/Utilities or via Spotlight, type in the below command and hit return.

chflags nohidden ~/Library

Alternatively you can hide it again by typing in

chflags hidden ~/Library

Get Drag Lock back when using a trackpad

Apple moved the Drag Lock preference from the Trackpad preference pane to Universal Access. Go to System Preferences > Mouse & Trackpad > Trackpad Options...

Change the Dashboard space background pattern

What to do:

1. Replace pirelli.png in /System/Library/CoreServices/Dock.app/Contents/Resources with a desktop picture of choice. Be sure the image matches the exact resolution of your screen and has a dpi of 720.

2. Make a second version of the desktop picture only this time 256 x 144 pixels in size (might depend on your Mac though) and replace mini_pirelli.png also located in the same directory as above. That way the background in Mission Control also gets changed.

3. Restart Dock.app using Activity Monitor or Terminal and repair disk permissions afterwards with Disk Utility.

End result:

Remove Finder sidebar items

In Mac OS X Lion and Mac OS X Snow Leopard v10.6.7 you now have to hold down the command key on your keyboard in order to remove items from the Finder sidebar.

Hide apps from Launchpad

You can use this tool to hide apps from Launchpad.

Get QuickTime Player 7 Pro back

Insert your Mac OS X Snow Leopard disc, go to the Optional Installs folder and double-click the Optional Installs installer. In the "Customize..." section you can select QuickTime 7. Alternatively you can also go to the below link and download the installer directly from Apple.

http://support.apple.com/kb/dl923

After installing the package you'll find QuickTime Player 7 in /Applications/Utilities

You can hide System Preferences icons you don't use often or ever...

(NOTE: You can also click and hold on the "Show All" toolbar button in the actual app window.)

(Just check off the ones you want to hide...)

Reverse the steps to bring them back, or just use the menu or the "Show All" button.

You kinda have to click-and-hold on the show all for the other hidden pref panes to be listed. I was really confused at first because the button appears to be greyed out. But I figured it out :D.

Excellent tips, some of them will make the transition from Snow Leo to Lion much more easy.

Only wish if Mission Control would keep apps more well organized like Expose in Snow Leo

I know this is a bit much to ask but ever since I have used Mac OS I have wanted to have an autohide menu bar - I would love if it functioned like when you're using full screen apps.

In Snow Leopard (according to Menu Eclipse developer) this was a no go for some reason - he might implement that in the next version since Lion supports it ( http://itunes.apple.com/app/menu-eclipse-2/id420041409?mt=12 - this version does not support it yet)

Since we're asking questions, any easy way to make applications launch in a new space (or automatically organise them so it's one application per space?)

I couldn't figure out how to make apps launch in a user-defined space (or Desktop, as they're now known) without actually launching it first. Once I did, though, you can secondary click on the Dock icon, go to Options -> Assign To:

The only thing I preferred in the older Spaces preferences was you could simply drag and drop app icons, without even opening them, onto whatever space you wanted. This seems impossible to do in Lion.

Hi,

What was the conclusion and perhaps solution on using a locale like danish or dutch on the login screen despite the OS itself being in the english language? I'm seeing US English locale for the time on the login screen and I'm using a danish keyboard layout and danish metrics. The Language is set up as Denmark - Danish.

Here's one to figure out, how do you reorganise the finder's sidebar so you can get shared and devices above favourites as in Snow Leopard.

I haven't been able to figure this one out.. I did find out that you can drag your hard disks to the favorites section and eliminate the Devices section - Optical drives, I think, will still show up. The Computer device can't be moved up into Favorites - or can it? You try it out :)

This is pretty much the only thing I want to do to Lion.

    • Researchers claim Microsoft's quantum breakthrough is flawed by basic Python errors by Karthik Mudaliar Microsoft's aggressive roadmap to deliver a commercial quantum supercomputer by 2029 has now hit a bit of a snag, and it's not because of a complex sub-zero dilution refrigerator, but rather because of a few lines of basic Python code. A new critique published in the scientific journal Nature argues that simple software errors effectively manufactured the breakthrough that Microsoft's foundational research claimed back in 2025 into Majorana-based topological qubits. Topological quantum computing, the path that Microsoft chose for its research, relies on creating and controlling "Majorana zero modes." These are exotic quasiparticles that theoretically offer vastly superior error resistance compared to the highly sensitive superconducting qubits currently being championed by rivals like Google and IBM. However, physically proving you have created these particles requires sifting through massive amounts of complex electrical conductance data to isolate a specific "topological gap." Because of the sheer volume of data, physicists rely heavily on custom software pipelines to process the results. This is where the Python scripts come in. Now, according to the critique, Microsoft’s data processing software contained fundamental programming errors that ultimately skewed the published results. By mishandling data arrays or deploying incorrect logic within the Python script, the software supposedly discarded "noisy" or contradictory data. Which is why it only highlighted the specific electrical measurements that supported the topological-gap claim. The researchers behind the critique argued that this makes the findings invalid, suggesting the heralded "quantum leap" was actually a false positive generated by bad code and not a product of groundbreaking physics. However, Microsoft is pushing back hard against these allegations. The Redmond giant has formally rejected the criticism, saying that it's just a minor anomaly rather than a fatal flaw. According to the company, while there may have been a minor oversight in the data parsing scripts, it does not alter the fundamental reality of their physical experiment. Just weeks ago, Microsoft unveiled the Majorana 2 quantum processor, a milestone so significant that the company boldly accelerated its timeline for a commercial quantum supercomputer from 2035 down to 2029. But the new software allegations reopen an old wound. Microsoft's quantum division faced a remarkably similar crisis when a landmark 2018 paper on Majorana particles was famously retracted in 2021 after independent physicists discovered the data had been inappropriately cropped. That historical baggage makes the current Python-related allegations particularly sensitive. If the foundational math and data processing for the 2025 breakthrough are genuinely flawed, the highly anticipated 2029 commercial timeline could easily be delayed or, worse, cancelled.
