Welcome back to Ask TUAW, our weekly troubleshooting Q&A column. This week we've got questions about the Trash, Migration Assistant, Safari Bookmarks, Mac mini Server, Windows and Mac file sharing and more.

As always, your suggestions and questions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Snow Leopard on an Intel Mac if you don't specify). And now, on to the questions.

CL asks:

Is there any way to just delete a single item in the trash can? I only see options to empty the entire trash can?

Unfortunately, as they say in computer parlance "That's a feature, not a bug." At the moment, Apple only allows you to go for an "all or nothing" approach to emptying the trash. Of course, the best solution is to only put things in the trash you want to delete. But I'm sure you already thought of that.

I will be upgrading from my current February 2007 Macbook Pro that is running Leopard to a new October 2009 MacBook Pro that is running Snow Leopard I plan on transferring my data via the "Migration Assistant" but being that this is the first time I perform this type of operation ... I want to make sure that I do not run into any issues.

Are there any precautions I should take? My other concern is that I backup my current 2007 MBP via Time Machine to my Time Capsule. What will happen to that data once I switch over to the 2009 MBP? Will I still have access to that data? Will it be rendered useless?

Migration Assistant has been around for several years now and has evolved and become better with each successive update. There was a time when I would never consider using it and did things the manual way by copying each and every thing I needed individually from an old Mac to a new one. Now, Migration Assistant is good enough and, more importantly, reliable enough to be used on its own. So, migrate away.

"Ever wanted to rid the web of the scourge that is Adobe Flash, but still retain the ability to view Flash whenever you want?" When it comes to sales pitches, that one is pretty difficult to beat.

Ever since Flash was unleashed on the web, it has been used for obnoxious and annoying ads. About the only web technology which has been more frequently abused is the animated GIF. For as long as I can remember I have disabled Flash, or plugins entirely, to avoid the annoyance. Firefox users have had extensions which manage flash, but Safari/Webkit users have been left out in the cold.

Several months ago someone created a now-defunct project on Google code simply called "clicktoflash". The premise was simple: replace all instances of Flash with a subtle grey box, and if you want to load it, click it (hence the name). The project was abandoned and deleted nearly as quickly as it appeared, but fortunately it had already been "forked" by Jonathan 'Wolf' Rentzsch who now maintains clicktoflash at github (which reminds me, TUAW is now on Github too).

Newer versions include the ability to "white list" a domain (meaning that Flash will always load for pages from certain sites) or load every Flash object on a page, rather than having to click all of them separately. It will also alert you of new versions and lead you through the installation process in a matter of clicks.

If you visit YouTube you will also find that if you control-click on movies, you are given a chance to load either the Flash OR H.264 versions of movies, or open the movie in QuickTime Player, or download the H.264 version. That alone makes it a great addition to any Mac. Be sure to checkout the settings under the Safari > ClickToFlash menu for additional controls.

I first learned about ClickToFlash from John Gruber who noted ClickToFlash is "a legitimate browser plugin that goes in ~/Library/Internet Plug-Ins/, not a dirty input manager hack. I can't remember the last time a piece of software made me this happy." I have to agree. ClickToFlash is a perfect example of "addition by subtraction" proving that you can make something better by taking something else away.

ClickToFlash is a free download and supports Tiger, Leopard, and Snow Leopard. It requires Safari 3 or higher.

Welcome back to Ask TUAW, our weekly Mac troubleshooting Q&A column. This week we've got questions about target disk mode, energy saver prefs, Safari file issues, iTunes album artwork, iTunes sharing and more.

As always, your suggestions and questions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Leopard on an Intel Mac if you don't specify). And now, on to the questions.

computergeeksjw asks:

I have an old iMac Blue G3. The fliesystem failed, but I can't reformat because there is a disc in the slot-loading drive. I tried the tricks I know like Open Firmware (gives me a weird error) and holding in the mouse button (I hear the drive spin up but nothing else happens). I have a newer G4 Quicksilver. Will it be able to boot up into Target Disk Mode even though the filesystem is damaged? (Then I can try to repair with Disk Utility or reinstall from there) or will it fail like a normal boot does?

There will be a day in the not-too-distant future when playing 3D games in your browser -- without extra plugins like Flash or Unity -- will be a reality.

The WebGL project, which has quickly made the blogging rounds this morning, combines aspects of HTML 5, JavaScript, and the OpenGL 3D drawing engine in an effort to create 3D graphics that appear right in your browser. Thus far, it's only beginning to show up in WebKit (the engine powering Safari and Google Chrome), but the glimpses as seen in the video above really show the power in these browsers.

Snow Leopard has brought a host of improvements to OS X, but Safari has been changed in one way that could ruin your day if you're used to using third-party plugins. Support for Input Managers has been removed in 64-bit Safari, which means that popular Safari plugins like Saft won't work.

Getting these plugins to work again in Safari is easy, but there is one tradeoff to keep in mind.

Re-enabling plugin support for Safari is as simple as forcing Safari to start up in 32-bit mode. When you choose "Get Info" on Safari, you'll notice a checkbox in the window that says "Open in 32-bit mode." Check this box.

That's it. Safari will now open in 32-bit mode, and any Input Manager plugins you were using before upgrading to Snow Leopard, like Saft or PithHelmet, should work just fine. Additionally, running Safari in 32-bit mode allows Multiclutch's custom trackpad gestures to work; these weren't working for me when I ran Safari in 64-bit mode, probably because Multiclutch is a 32-bit prefpane.

There's one caveat to running Safari in 32-bit mode: there's a tradeoff in stability. One of the features you gain by running Safari in 64-bit mode is that Safari will "sandbox" plugins like Flash, so if (when) Flash Player crashes, it doesn't take all of Safari down with it. This is because when Safari runs in 64-bit mode, plugins actually run as their own separate processes rather than being bundled up with Safari. But when Safari is run in 32-bit mode, Flash and other plugins work the old way, which means if (when) Flash crashes, so will Safari.



If you can't live without your plugins (and I can't – Safari without Multiclutch or PithHelmet is like a day without sunshine), then the small sacrifice in stability you'll suffer by running Safari in 32-bit mode is probably going to be worth it to you.

Note: if you're running anything that runs off the SIMBL input manager plugin like Saft or PithHelmet, you might have to take a few extra steps to get things running properly in Safari on Snow Leopard. This procedure is specifically tailored toward getting PithHelmet running, but the steps for Saft should be similar (Procedure courtesy of versiontracker.com user tech.bear).

Hot off the Software Update express it's Safari 4.0.3, which Apple's verbiage states:

This update is recommended for all Safari users and includes improvements to stability, compatibility and security including:

• Stability improvements for webpages that use the HTML 5 video tag
• Fixes an issue that prevented some users from logging into iWork.com
• Fixes an issue that could cause web content to be displayed in greyscale instead of color
• For detailed information on the security content of this update, please visit this site: http://support.apple.com/kb/HT1222.

Go on, download it and let us know if unicorns appear in your browser. The update requires a restart.

Fire up Software Update, Apple just released Safari 4.0.2!

As usual, the release notes are extremely informative (laugh), stating:

This update is recommended for all Safari users and improves the stability of the Nitro JavaScript engine and includes the latest compatibility and security fixes.

Looking a the actual security announcement, this is is one update you're going to want to install. One of the security fixes addresses potential cross-site scripting attacks, via WebKit's handling of parent and top objects. The other fix addresses memory allocation for numeric character references, which if exploited, could allow arbitrary code execution or application termination after visiting a malicious site.

These issues affect Mac OS X and Windows XP and Vista, so everyone, download your Safari updates!

As usual, you will have to restart your computer after installation.

I realize I may not be your average browser user. As a web developer, a browser to me is two parts daily use, two parts testing, and one part challenge. Since 2005, I've been using Firefox in some form or fashion as both my primary browser and as a testing vehicle.

I had recently started a JavaScript-intensive project, and I appreciated Safari 4's lightning-fast JavaScript execution speeds. In Firefox, I rely mostly on add-ons like Web Developer and Firebug to help me analyze and test for mistakes in websites I build in Firefox. They work great, but enabling them slows the browser down.

That's why I was excited for the updated Web Inspector that comes as part of Safari 4. (Yes, Safari 3 first came with Web Inspector, it couldn't hold a candle to Firebug's Swiss Army knife of an add-on for Firefox.) Testing was easy, and Safari 4's Web Inspector's many improvements made me think I could migrate to Safari full-time.

Read on to see how it went.

I guess the iPhone 3.0 update and Safari 4.0.1 weren't enough for Apple. Along with the just released update to Safari, Apple has just tossed in one more Software Update:

Bluetooth Firmware Update
"This update provides bug fixes and better compatibility with the Apple Wireless Mighty Mouse and Apple Wireless Keyboard. It installs on all Macintosh systems with Bluetooth based on the Broadcom chipset."

This update is only applicable to certain hardware configurations (as noted above), so if you don't see it, you don't need it. After running, the Bluetooth Firmware update will provide you with an installation screen and require a reboot when it's done.

I wonder if Apple will throw us any other new surprises today.

Digg's Kevin Rose, perennial purveyor of information that just "fell off the back of the truck" shared a link early this morning to Google's new, supercharged, Webkit-based browser -- for Mac.

The new browser, Chrome, is clearly marked as a developer preview, and not meant for general browsing. In fact, as a good Mac citizen, it will refuse to set itself as your default browser.

It scores a 100 on the Acid3 test straight out of the box, but doesn't pass: it fails something called the linktest, which involves interacting A tags and IFRAMEs. A little research suggests that it could be a bug with Webkit. If that's true, then it's a bug that Safari 4 beta has fixed.

Chrome appears to have Flash (and other plugin) support disabled as well. JavaScript support, however, is fully functional. While Chrome performed much better than Firefox on this cursory test, it still didn't beat Safari 4 by a long shot. While only a beta, its performance is respectable and sure to improve.

Again, Google Chrome isn't for everyone, but if you're a web developer who needs to keep up with the bleeding edge of browser development, then this preview should be stable and reliable enough for you to test what you need to.

Read through for the full JavaScript test details.

Thanks to everyone who sent this in!

If you're looking for a bright spot in the Mac market share numbers after the recent dips, Net Applications has your back. The May survey indicates an uptick in Safari's share of browser usage -- up to 8.43% from 8.21% in April, and 2% higher than a year earlier. Firefox continues to be the big 2nd banana to leading browser choice IE, with a 22.5% share. It's not yet clear how the IE8 release will drive browser adoption.

Operating system numbers (which aren't definitive, but provide a reasonable indicator of usage) also show a slight rise for Mac OS X (9.81% from 9.73%), also more than 2% over the year-ago allocation.

On the mobile side, the survey company notes that Android browsing usage started out with the same adoption curve as the iPhone/iPod touch, but has since fallen off that pace. Coverage of the Palm Pre starts soon.

It was one of those slow weekends. A good time, I thought, to clean up some odds and ends on my to-do list. Often, my list involves things relating to my computers, and this weekend was no exception.

Item #1. Install Windows 7 RC1 using VMWare. I didn't have a super urgent reason for doing so, but the time seemed right. I went to the Windows 7 download site, followed the instructions and the download never started. Just an animated thingy. I assumed the Microsoft Servers were busy, so just let it go. A few minutes passed. The thingy kept spinning. Finally, after an hour I said the hell with it. Oh, I wasn't just staring at the screen for an hour. I DID have other things to do.

I tried again later in the day. I thought, well, maybe this download is really popular, but it has been out for a few days, and certainly Microsoft has plenty of bandwidth. I tried a few tests downloads of other things, and everything was peachy.

Just for the heck of it, I tried downloading the RC with Firefox. Blam! It started right away. I'm sure other people know this, but a quick Google didn't give me any obvious joy. For whatever reason, Safari just won't connect. A subtle message from MS? Or just one of those things? Anyway, save yourself some frustration, and use Firefox. It just works. (Note: there were some comments about this in Steve's Windows 7 post)
