Why are there so few printers that airprint supports?

i am curious to find out if anyone knows why apple was so selective on printers that airprint would support. i have a hp photosmart c7280, it has wi-fi capabilities but alas is not in the "list" of printers that apple says will work with airprint. why? instead i have to rely on a 3rd party app (print magic) to do that. print magic is a good app but i would figure that apple would want to give prefference to it's "own" software rather than someone elses. why have it as an option is in ios 4.3 if it wont work with any wi-fi printer?

Some folks have reported good results with Photosmart using the following workaround:

Why are there ads in games that I have purchased? Can I get rid of these ads?

Why are there ads in my games that I have purchased. How do I get rid of the ads?

The developer participates in the ad program to provide income, usually in exchange for offering the application for free or at a low price. Some developers offer an ad-free version of the app at a higher price, so you might look for that possibility. If they only offer a single version, though, then you're stuck with the ads, though you can urge the developer to offer an ad-free version as well.
Regards.

Why are there so few games for Mac OS X?

Yes, I do know the answer, because everybody writes software for Windows.
But aren't we at a point where times are changing? Many people exchange their PC's for a Mac nowadays, and the number of Linux (which is basically the same under the hood) is rapidly growing too. Those people like to play games too, don't they?
Does anyone see some light in the distance for companies porting their games to the Mac too?

Agreed. You have to remember everything is drive by economics in our capitalistic society so games are written for the OS that has largest market penetration and most likely to return huge profit and currently that is Windows. That is also why one of the most famous game programmers, John Carmack, just recently rewrote some of his games for iPhone/ipod touch and made quite a nice profit from his own account.
"Carmack said that there was a lot of "hand wringing" initially over the idea of spending the company's own money (there was no publisher to help fund development) on making games for the iPhone. Doom Resurrection, when it hit, was probably the most expensive game to develop for the iPhone, Carmack says.
"It did really well for us," he said. "It was Wolfenstein Classic that made the argument for iPhone development for me. We made quite a bit of money off of that."

That is not to say that Mac's can't be used as game machines since Apple actually has a webpage dedicated exactly to this you can check out:
http://www.apple.com/games/hardware/
So in a nutshell to answer the OP question the reason you see fewer games on mac's is because it's not profitable. As you can see if there is no technical limitations writing games like Doom3 for iphone there is none for the mac.
I know I've personally not bought a macosx game since I also have a pc and use that for games so I'm not helping the business case for more games for mac. Vote with your pocket and go out and buy more mac only games if you want to see more for the mac.

HT4623 Why are there some purchased albums that can't be downloaded?

There are several albums that I bought and need to download, but when I go to the album, it says "purchased" and there's no option to download. I also went to purchased albums, and it isn't in there.

Because the developers do not make them available in all countries.
You can ONLY buy from the itunes store of your country of residence ( as proven by the valid billing address on your credit card) AND you can ONLY buy while inside the borders of that country.

Why are there little blue dots that appear next to my movies?

There are little blue dots that appear next to the movies that i have started to download. Also i just started to download a movie, and i am not sure if it is even downloading. Please Help!

The blue dot just means its new (meaning you havent watched it yet). You should see the same blue dots next to Text Messages and Emails that you have not read.
You can check your current downloads in the iTunes Store App > Tap more in the bottom right > Tap Downloads.

Why are there 4 x emails that I CANNOT delete?

Hi lovely people.
Whilst pruning the emails in my Mail boxes I found 4 x emails that I CANNOT delete. They're grayed/ghosted and no matter what I do to get rid of them (according to the useless Mail Help anyway) those emails have stuck like glue! OMG why?

Not certain, but this can fix myriad Mail problems...
Safe Boot from the HD, (holding Shift key down at bootup), it will try to repair your Disk Directory while the spinning radian is happening, so let it go, run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then move this folder & file to the Desktop.
Move this Folder to the Desktop...
/Users/YourUserName/Library/Caches/Mail/
Move this file to the Desktop...
/Users/YourUserName/Library/Mail/Envelope Index
Reboot.
If that doesn't do it and you can afford to redo all your Rules, try these & reboot...
/Users/YourUserName/Library/Mail/MessageRules.plist
/Users/YourUserName/Library/Mail/MessageRules.plist.backup
Note, in 10.5 & up /Users/YourUserName/Library/Caches/Mail/ may or may not exist.

Why are there so few genres for tv shows on the Apple TV?

Missing genres:
Classics
Independent
Documentaries
Family
Action and adventure (thriller)
Fantasy
Romance
Sci-Fi
Foreign
Sport
Music
Is it just that Apple's tv show collection is not large enough to match the genres?

Unfortunatly, the market for developing apps for mobile/tablet devices is much greater than the one for computers. Depending on what kind of applications you are looking for, you can find decent apps online that may not be available on the app store.

Why are there so many apps and wearable tech out there that specifically focuses on losing weight?

I'm under weight and would really like to see some apps for people like me who want to gain about 30 lbs!

Why are there so many apps and wearable tech out there that specifically focuses on losing weight?
Because there's a 35x bigger market for it.
Percent of adults age 20 years and over who are overweight, including obesity: 69.2% (2009-2010) - http://www.cdc.gov/nchs/fastats/overwt.htm
...an estimated 1.7% of U.S. adults aged 20 and over are underweight - http://www.cdc.gov/nchs/data/hestat/underweight_adult_07_10/underweight_adult_07 _10.htm
I suggest you type
weight gain app osx
into a search engine. I did and one came up on the top line (no idea if it is any good, you have to determine that yourself).

HT1386 why are there 0's in some folders that i put photos in in iPhoto when I veiw it in iTunes?

why are there 0's in some folders that i put photos in in iPhoto when I veiw it in iTunes?

Those files should be being created in folders of the form:
<User's Music>\iTunes\Album Artwork\Cache|Download\<GUID>\<##>\<##>\<##>
The <GUID> in your case is 0CDB362F24AD473A...
If they are appearing anywhere else I would suspect a permissions problem. iTunes just spits them out where it can. Similar problems can sometimes cause it to drop files on the desktop.
Repair Permissions
Right-click on your main iTunes folder and click Properties, then go to the Security tab and click Advanced. If necessary grant your account and system full control to this folder, subfolders and files, then tick the option to replace permissions on child objects which will repair permissions throughout the library. This is the XP dialog but Windows 7 shouldn't be too different.
Once you've repaired the permissions search for all files of the form *.itc2 in the music folder and delete them, then start iTunes. iTunes will rebuild the artwork cache in the correct location as you scroll through your library.

HT204150 Why are there contacts on my iPhone that are not on my Mac (syncing through iCloud)

Why are there some contacts on my iPhone (and my older Mac) that aren't getting synced onto my new MacBook?

First check that all your settings are correct, that contact syncing is checked on all devices (system preferences > iCloud on a mac and settings > iCloud on a iPhone, iPad or iPod).
Make sure the contacts you are adding are added to your 'iCloud' group and not an 'On My Mac', 'On My Phone' or other non iCloud group (you can do this by checking in groups), non iCloud contacts will not sync.
If you are sure that everything is set up correctly and your contacts are in the iCloud group, you might try unchecking contact syncing in the iCloud settings, restarting your device and then re-enabling contact syncing.

Why are there no sounds located in the Library/Sounds folder in Home Directory? My Mail alerts, etc

Why are there no sounds located in the Library/Sounds folder in my Home Directory? Since upgrading to Mountain Lion most of my sounds are not working, in my Mail alerts, etc.

Did you put any sound files there? Because if you didn't, that will explain why it's empty.
The ~/Library/Sounds folder is where any sound files that you add go, and they are only available to you as the "logged in" user (if you have other users with their own accounts, they each have their own ~/Library/Sounds folder). Apple doesn't put anything there.
The sounds that come with Mac OS X will either be in the /Library/Sounds folder (which is the shared location for all users) or the /System/Library/Sounds folder (don't mess around with anything in the /System folder!).
But I doubt your problem has anything to do with the sound files. Try deleting your sound preferences file, or even just clicking around in the Sound system preferences until they start working again (seriously - I had one Mac that had some audio problems after upgrading, and just turning things off and on a few times eventually worked. It seemed somehow tied to Dictation, so try twiddling those settings too).

Why are there so many more choices on the USA iTunes Store? Surely having an iTunes account should let you access all itunes availability the world over? Also how do you request films/tv series to the UK itunes?

Why are there so many more choices on the USA iTunes Store? Surely having an iTunes account should let you access all itunes availability the world over?
Also how do you request films/tv series to the UK itunes? There's tv series I'd like but they're incomplete like The Batman & Xena Warrior Princess. And films theta aren't available for download but you can purchase in a store like HMV? Apple isn't doing itself any favours by secluding countries by their store. They'd make billions if you could just select the iTunes Store you want to search & purchase from just by signing in! If anything what they're doing is putting themselves into a corner, other companies like Samsung & HTC are already on too of them for innovation & ease of use. The people they're attracting are predominantly existing Apple users not new customers. What do you guys think?

It's not Apple's choice, they can only sell a particular item where the content provider/rights-holder has granted them a license to sell them. Content is licensed by the rights-holders to Apple on a country-by-country basis, each country therefore has to have its own store, and you have to be in a country to use its store - they want control over where their content is available.
You can try requesting that an item be added to the UK store via this page, but unless the rights-holder agrees to then Apple won't be able to sell it here : http://www.apple.com/feedback/itunes.html

Why are there so many flash updates?

Why are there so many Flash updates… I have had two in the last week and at least one more since the start of the year. It seems to have really got silly this last 12 months, is Flash really that unsecure and unstable that it needs this many fixes and updates?
I know you can tick the install in background box when updating but I like to know what is going onto my computer and given Adobe's knack of crashing my system when using PS and AI I don't really want them silently installing anything.

99% of the time the update gets prompted by Youtube or BBC when videos won't play on there sites and I follow the links through them. You would like to think that big sites like these would not allow false links to malware to crop up, but it isn't out of the question. Next stop, up to date anti virus…..
As far as Youtube goes I thought they had adopted HTML 5 now as standard and didn't rely on Flash?

Nas on airport extreme not recognized by time machine. same nas was previously used as time machine backup on different airport extreme. are there any configuration files that i can delete to fix this problem ?

nas on airport extreme not recognized by time machine. same nas was previously used as time machine backup on different airport extreme. are there any configuration files that i can delete to fix this problem ?

Time Machine has been working just fine, but in the last week or two it has given up the ghost. I reset the connections to the drive, and it will basically save a few bytes of data and then hang.
Although Apple originally announced, prior to the release of the first 802.11n AirPort Extreme Base Stations (AEBSn), that it would support Time Machine backups to AirPort Disks, they removed that option before they did finally release the base station for sale.
Since then, Apple has posted (as you have noted) that they DO NOT support Time Machine backups to AirPort Disks. As far as I know, they have not changed from that position and those who do these backups find that they become corrupted over time. Sorry, but it sounds like you just confirmed that for yourself.
1) Has one of the recent updates either on the AE (firmware) or OSX disabled this function?
No. Again, this feature has never been supported by Apple for every generation of AEBSn released.
2) Are there any changes I can make to get this working again?
If your data backups are critical to you, then you will want to use a different solution for your Time Machine backup destination drive strategy. I would suggest that you connect your WD My Book directly to your Mac in the mean time.
Your other options would be to either use a Time Capsule (which interestingly does support TM backups to AirPort Disks) or a non-Apple solution like the Drobo FS or HP MediaSmart server.

If i am the only user and owner of my macbook, then why are there 78 users in the directory editor?

Hi guys just wanted to know little bit about the open directory as my MacBook Pro has been playing up on and off at least a couple of years. I have been advised by Apple over the phone or as well as over the genius bar in trying to get my mac to behave. This normally solves whatever problem that has been happening at the time. "Great, job done!"... Not so much, as another problem eventually shows it's ugly pixelated face again and then we end up going round the Infinite loop ride one more time... And this ride ain't always free! I have forked out about £600 on it so far and it wasn't cheap in the beginning! Anyway I have just got off the ride and before I get punched by a plyst to get back on I would rather learn about the things I don't understand so hopefully I can resolve the matter without hair loss. So my main question so far is why are there 78 user names (most of which are computer related names, not all) are found in Directory Utility? I do not play games on my Mac it is mainly used for media such as iPhoto, iTunes, pages, mail and surfing the net. So which out these 78 users do I select as a server?
If you have any suggestions or pointers then please post a reply.
Thanks for reading
Orion

So which out these 78 users do I select as a server?
None. It's normal. Make no modifications.
It's not clear what trouble you are experiencing, or if anything is wrong at all. If your Mac is not behaving as you expect it should, describe what's wrong in as much detail as possible.
Include all relevant details regarding your MacBook Pro starting with which one of its three dozen models you have. Posting the results of EtreCheck will help with that. Read about it here.
