Hi, this is Gary with a little more relaxed version of MacMost Now for Monday.
We're going to take a look at some of your questions.
So, I noticed over the weekend that there were some messages in the inbox in the YouTube account for MacMost.
Now I hadn't been checking it, thinking everybody would send me messages at or through comments on the website, but there were some on YouTube so I figured, "Hey, today, let's go and take some time and just run through them." I printed them out and let's just look through them. I don't know all the answers, but I'll be able to point some people in the right direction.
Sabarras has a question here:
Uh, he says his Dell computer crashed a week ago and he's getting a new one and he wants to know about syncing his iPod to multiple computers. Should he do this with his new computer?
Now, I'm not sure if he means syncing with the old machine and the new machine, both, or if he's got another computer on top of that, but it does bring up a really important point: If you're retiring a machine, it's really important to go on iTunes and deauthorize your iTunes account for that machine. See, you get about five authorized machines where you can play back the music you purchase at the iTunes Music Store. Now, if you give one away -- say you wipe the drive, and give it away-- that machine's still authorized. Now, you can contact Apple and have them deauthorize that computer but it's a lot easier if you actually remember to deauthorize that machine and then, of course, make sure you transfer all your iTunes music and everything else using something like Migration Assistant over to your new machine....and of course, if you are using multiple computers, sure, go ahead, sync it will all of them.
Here's an email about viewing tutorials full screen. So, in full screen mode, and I think, talking about the collection of MacMost tutorials, so of course many of these MacMost Nows are tutorials:
Um, well, there aren't any full screen versions. I mean, there's only the high resolution version. I publish everything at 640x360, which is pretty hi-res for most stuff on the web. You can actually see hi-res versions at YouTube by clicking on the little hi-res button in the lower right corner of of the YouTube interface. Um, you can also go to our main website, and look at the videos there are pretty high resolution and you can follow the links back to and look at the MacMost feed which has all of the original hi-res versions. So the ones I actually published, they can be found at and you can watch it as high resolution as you want.
C. Marshall asks, uh, "In some of your vidoes, there's an apple II in the background. Can I have it?"
No, you can't.
Let's see, Ray asks, uh, "I'm wondering if you know of an application I can use to run a music video and music on my computer and split it into three tvs?"
Uh, I get the idea here. You wanna have basically a big display with say, three tvs and have the video split between all three of them. Well, what you're probably going to need is a hardware solution more than anything else. Uh, if you have something like a MacPro Tower, you of course can get multiple video cards. Uh, if you don't that, you're going to have to figure a way to actually split the video signal. There are some hardware devices out there that'll split a VGA signal onto multiple screens. Of course, you can also get devices like some of the display link technology we've talked about in past episodes where you can add multiple monitors. This won't help it get onto a tv screen unless the tv screen has an easy way to convert a VGA or DVI signal to the tv but you can also get some other hardward that will allow you to export the video coming out of your computer from say a DVI or VGA signal into one or more tv monitors. So, it's hardware that you want, not software.
Blue Seas is having trouble with something called Safair Extender, something he installed on his machine, and he wants to uninstall it now and he's having trouble uninstalling it.
So, when you install one of these apps whether its an extension for safari or an extended little application, it's..if you want to uninstall it there's a lot of little things you gotta do usually. You want to remove it from your applications folder of course. You also want to look in the library folder, both the main system folder and your personal one and see if there's a folder there for that application and look in the applications support folder inside of the library folder for things. Then you wanna look in the preferences folder for a preference file. Sometimes a preference file will start with com dot and the company name dot application name so you have to look really all over for that. Now, another thing if you're stumped or if you just want an easier solution, sometimes I just google search for uninstall and the name of the application, or remove and the name of the application and usually somebody else has put up some steps on how to uninstall that app. For Safair Extender, I saw several such things.
So, that brings us up to date on at least the questions I wanted to take a stab at in the YouTube inbox. In the future, you can always to send a question or just a comment. But, if you're sending a question, remember, if it's too specific, I'm probably not gonna answer it. I mean if it's for a specific type of printer, a very specific type of device, chances are, I probably don't have it, I can't have everything, so I won't be able to answer the question, but if it's a more general type of question, and especially one that'll help out other viewers, I'll be more than happy to answer it. Until next time, this is Gary Rosenzweig with MacMost Now.
