Ask TUAW: WiFi on an older PowerMac, creating contact sheets, managing iPhone apps in iTunes, and more
We're back with another shot of Ask TUAW! This time we've got questions about getting WiFi in an older G4 PowerMac, creating photo contact sheets, blanking a display, automatically opening downloaded files, managing iPhone apps in iTunes, and more.As always, your suggestions 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!
The Echidna asks
I currently have a dual 867 MDD with a 'generic' 802.11g card in it using the OrangeWare driver, which doesn't work with Leopard. I desperately want to upgrade to Leopard, I have done it before and know it works... but I also need the WiFi functionality of G which isn't offered in the supported Airport card.

I'd recommend checking out the nQuicky PCI ($99.95) from QuickerTek. It's a little pricey, but it claims compatibility with G4 PowerMacs with a PCI slot, and indeed offers the much faster 802.11n spec.
iGO asks
Is it possible to make a "contact sheet" on my iMac 10.5.6? I want like an 8x10 sheet with say 30 to 35 little 1x1.5 inch thumbnails. Like a photo proof sheet for allowing users to pick the pictures they would like printed.
Well, this is a built-in function of iPhoto in the print dialog, so that would be the easiest solution if you already have iPhoto. If you don't want to use iPhoto, Automator might be a good way to go. There is a built-in New PDF Contact Sheet action, which will allow you to construct an Automator app to do what you like (check out this tutorial from Apple). If you want a little more control you might also have a look at this third-party Create Contact Sheet Automator action with which you can easily build an Automator application.
If you're willing to spend a little, Graphic Converter ($34.95) has some interesting tools for what they call "catalog creation." Obviously, many more expensive graphics apps also have this kind of functionality as well.
ax sedrin asks
I have my 37" HDTV hooked up to my iMac (24" intel, brand new, OS X 10.5.6) as a second monitor, and I'm using Plex as a media center on my HDTV. The problem is, with the iMac in the same room as the HDTV, the screen is very bright and distracting during movies. Is there any way to turn off the display of just the iMac (and not also kill the video to the HDTV)? Or is there a simple program I can run that will "black" out the iMac screen?
The handy little application Backdrop (donation requested) will allow you to put a solid black screen fill on the display of your choice. It's not exactly the most elegant of solutions, but it will help. I'd also recommend making the HDTV the primary display in the Displays Preference Pane so that the menubar will be located on it rather than the iMac's display.
Eug asks
Back when i used IE in windows xp, and clicked a URL that links to a document (doc/xls/ppt), it would ask me to save or open. in OS X these just download by default. only PDF is opened within Safari. is there any way to have the option to save or open the file, rather than just have it save?
I don't believe there is a way to have Safari ask you want you want to do on a case by case basis. However, there is a setting in the Safari Preferences that will allow you to automatically open "safe" files after downloading. However, I really would not recommend turning this one, because it presents a potential security risk.
There is a Word Browser Plugin available for Safari, which will do basic display of Word files in a window; you can download it here.

If you use Firefox, on the other hand, you can turn on the"Always ask me where to save files" checkbox in the general preferences; at least then you have the option of picking your save location.
Unregistered asks
How do I clean up my iTunes? I currently have a lot of free apps that I grab during their giveaways or heavy discount periods. While I don't use them all there are quite a number that I would like to keep for future use. Can I burn the whole Mobile Installation folder to DVD and then delete those that I don't need for the time being? Will the backed up apps work by simplying dragging back from the DVD?
It seems that iTunes treats iPhone applications more or less the same it treats music tracks. So if you right-click on an app and choose to delete it, iTunes will ask you if you want to move it to the Trash or leave it in your Mobile Applications folder (generally ~/Music/iTunes/Mobile Applications). If you tell it to leave it in Mobile Applications you can then re-add it to iTunes simply by dragging and dropping. That way, you could conceivably delete the applications you don't want, but archive them on a DVD which would allow you to re-add them at a later time if you so chose.
Khalid asks
Is there an easy way connect a Mac Mini to my HDTV using HDMI? I am planning to buy one but don't want to spend 800$ and discover that it doesn't work or has poor image quality (I want a quality as the Apple TV).
This should be no problem. HDMI is a superset of DVI, so you all you need is an HDMI to DVI cable like this one from XtremeMac (~$20) as well as a Mini-DVI to DVI adapter ($19) from Apple. This should allow you to plug into your HDTV and run at the full resolution supported by the display. Reader Carlos points out that this HDMI arrangement will not relay the audio from your machine, so you'll need a separate audio patch cable.

Khalid,
Monoprice.com has a Mini Display Port to HDMI Adapter for around $13. Haven't used it with a Mac Mini (yet) but it works perfectly with my Macbook Pro, Plex and my 1080i TV.

To turn off the iMac display just go to "Display Preferences" and turn the brightness down all the way. This will turn off the backlight (not just cover it with black pixels).

Re: Khalid. Video will work great but the resultant HDMI signal will NOT have audio. The MacMini does NOT output audio to the mini-DVI OR the DisplayPort. You will need a separate audio cable, preferably mini-Toslink to Toslink. If your receiver or TV can't mix audio and video from two different sources then you will need this:

and this:

Then you're golden.

I do this and it works perfectly. Monoprice all the way - get a DVI>HDMI adapter and a standard HDMI cable in the length you need and you are good to go. The picture is true 1920x1080 HD and looks great.
You can get surround sound by using a miniToslink>Toslink cable, also from Monoprice, to plug into a surround receiver. I think it's true Dolby Digital. It sounds great. Go for it.
Max said 12:48PM on 5-14-2009
Oh, and I suggested the dvi>hdmi adapter + hdmi cable instead of the dvi>hdmi cable because it's much cheaper, and in the future you can re-use the hdmi cable for something else.

Can't you also just put the display to sleep manually by pressing Shift+Control+Eject?

Johnny said 2:34PM on 5-14-2009
Doesn't that put both displays to sleep?

Another option, which I have tested and verified, is to use an Airport Express in client mode.
The beauty of this setup, is that the Airport can be transfered to work on any machine with an ethernet port.
Not to mention it comes in at the same $99 price point as the QuickerTek card and offers N speeds as well as plenty of more features.
Just a thought.

Good idea. It's worth mentioning that the older b/g models can't do this, though – it's only the newer 802.11n version.
SCOTT said 5:16PM on 5-14-2009
I beg to differ with your comment that the B/G Airport Express doesn’t do this...
I'm not sure what way it has to be set up again...but I do know that at one point my wireless adapter for my TiVo didn’t work...or I needed it someplace else...and I used an old USB to Ethernet adapter and plugged it into my Airport Express and was immediately connected to the Internet...with NO configuration needed...
so something tells me that if you need to connect your older Power Mac to the net wirelessly and still be able to use AirTunes function...which is what happened for me then the Airport Express will work...now you may have to use a USB to Ethernet adapter as well like I did with my TiVo but it can be done cheaply...and have the added convenience of the AirTunes and USB printer sharing capability
good luck

Note that some TVs won't accept input from the Mac Mini at the TV's native resolution, or at least will crop the picture (I have a Panasonic that does this, unfortunately).

I have the same issue on my Panasonic. To resolve it, go to Menu, Setup, then toggle Picture Overscan.
Hope that helps.

Im pretty sure that Plex has an option called "Display Blanking" somewhere in the preferences menu. I found it accidentally. It deactivates any other screens while plex is running. Quit Plex and the imac screen comes back on! Simple.

Thijs Poorthuis said 6:54AM on 5-14-2009
Indeed, there is an option like that in Plex. You can find it under 'Preferences - System' and it works like a charm..

I do some photo editing with Photoshop Elements 4 (on a last-gen, non-unibody 17" MacBook Pro running Leopard), and I have an annoyance I don't know how to get around.
I want to disable Photoshop as a default program to open any files.
Any time I edit a photo in Photoshop, it sets Photoshop as the default program to open that file, but I'm typically making simple wallpapers and things, which I really want to re-open with Preview, in all cases.
I can "Open With" Preview, and set it to "always" do this... but it seems to change it only for that file. Is there a way to change this setting globally, that all JPG, GIF and other simple image files open in Preview whether they were last saved in Photoshop or not?
Thanks!

Steve, try RCDefault.app, from here:

I've been using this Prefpane to change filetype associations and found it very useful.

That sounds great, thanks!

SCREEN BLANKING SOLUTION: I have a panasonic plasma and a 20" iMac Core2Duo ... I have had the same issue with the display blanking on the iMac while watching video on the TV ... The best solution I've found is Shades: http://www.charcoaldesign.co.uk/shades Freeware that allows you to control the brightness of the screens separately... it gets the iMac as black as possible while still having video on the TV - Command-Alt-Eject doesn't work, as it turns off BOTH screens - the brightness control built in doesn't go dark enough, but Shades is pretty good ... Also, it better supports the mirroring versus the extended desktop display options (when in mirror mode, it doesn't dim the screen - in extended, it goes auto-black)... I did this combined with some app I setup an applescript to switch between the two modes (in case I turned the TV off while still in extended mode) ... works QUITE well

The easiest solution to the Wi-Fi issue is to pick up a dedicated Wi-Fi bridge. It's a hardware device that plugs into your Ethernet port. No drivers required, you can use it on other devices (ie, DVR, Xbox, etc), cheaper than the PCI card (in the $75-80 range), and you don't have to open the machine up to install it. Linksys makes a model -- WET610N -- that supports dual-band N.

When you get an HDTV make sure that it doesn't have a huge overscan, or that you can turn it off on the TV itself. I have a Samsung 40" and it doesn't have a setting for overscan on the TV and its 2.5% overscan is how the TV was made, so I either ahve a 2 in black border around my picture (with overscan off on the mini) or it cuts off about 2in with overscan on on the mini.
