OS X is known for its intuitive and simple way to achieve common user tasks, but one area where it fails is in setting or changing the default app to open a given file type. New OS X users migrating from Windows may find it especially frustrating given the ease with which this can be done in Windows 7 and so on. How, for example, do you make all your video files open with Quicktime instead of VLC by default or pdf files to open with Acrobat instead of Preview?
Here’s the answer:
1. In the Finder, select any file of the given type you want to change.
2. Using the keyboard, press Cmd-i or right-click on the file to display the contextual menu, and chose ‘Get Info’.
3. About 2/3rd of the way down the tall dialogue box, you should see ‘Open with…’ and a menu button. Click on the menu and choose the app you want.
4. After clicking on your preferred app, click the ‘Change All…’ button. This means that not only this file, but all files with the same extension will open with the app you just chose.
5. Press Cmd-w on the keyboard or click the red ‘Close’ button in the top-left corner to close the dialogue box.
Well, you probably already have Kindle for iPad, but Amazon’s latest way to offer up your electronic texts, the Kindle Cloud Reader, could be the way of the future as far as non-App store developers are concerned.
Kindle Cloud Reader avoids the app store (and Apple’s 30% cut and other stringent conditions) by serving up your Kindle database through your web-browser. It’s basically a password protected web-site that also allows you to allocate offline storage space on your iPad or Mac OS (it’s not yet available for iPhone).
Amazon’s move follows in the footsteps of the Financial Times move in June this year to sidestep iTunes.
Cupertino, I think we have a problem…
Mission Control allows you to assign an app to particular desktop, so you can keep your work organised in different screens, and move between tasks with a swipe of the trackpad.
The easiest way to assign an app to a desktop is to first run the app so it appears in the Dock. Then, if you’re not already in the desired desktop, change to the desktop that you want the app to always appear in.
Next, place the cursor over the icon, and right-click (or two-finger tap if you have this gesture set for the trackpad).
Amazon have now made a Lion-compatible download available for Kindle for Mac here. Be aware that you may have to delete your current Library and re-download your purchases from the Archive. If you have a lot, you can just do this on an as-need basis or you could just spend the time doing it all in one go straight away.
Note that the update hasn’t appeared in the Apple app store at the time of posting.
Developing apps for iPhone, iPod, iPad, and Mac OS seems like the California gold-rush of the 21st century — the press are full of reports of the riches to be had in this amazing land, stories of “little people” making “big bucks”. Anyone can be an app developer, they say, but what’s the truth behind the hype, and how do you actually learn how to do it?
Last I heard, there were currently something like 600,000 apps on the Apple App store (for iPhone/iPad) and some 100,000 or so on the App store for Mac OS. Apple have paid out (i.e., passed on customer payments after taking their 30% cut) literally billions of dollars to developers. That’s a lot of cash! The question is, can you get a slice of it too?
In theory, there’s no reason why not. As I’ll detail below, the route to becoming an app developer is not particularly hard, nor is it particularly costly. But that doesn’t guarantee success. Anyone can write a book, but writing a killer book that’ll sell like Harry Potter is not so easy, and writing a killer app that will sell like Angry Birds is every bit as difficult.
The analogy holds for success in both cases: you need a great idea, you need to execute it well, and you need to market it properly. Did I mention those 600,000 apps on the App store? How, exactly, are you going to make your fortune if your app is buried in a pile like that? Well, I’ll save ideas and marketing for a future post. In this one, I want to focus on the things that we know we can achieve and only have to depend on ourselves for: developing the skills needed to turn that great idea into an actual piece of software that will run on Apple machines.
Learn the language
If you want to write a killer novel, the first thing you have to do is learn the language that you want to write the novel in, be it French, Chinese, or English. If you want to write a killer app, the same goes. Visual Basic? Visual C++? Java? Yes, that kind of thing except…if you’re developing for iOS (the iPhone/iPad operating system) or Mac OS (Mac computer operating system) you have to learn the Apple language, not any of those common ones associated with lesser machines!
So what is the Apple language? It’s called ‘Objective-C’, and it runs in a programming environment called ‘Cocoa’. You’ll need to learn ‘Cocoa’, but in order to learn that you’ll need to learn ‘Objective-C’, and to learn that, you’ll need to learn the basics of the standard (Ansi) C programming language. Oh my!
And once you’ve got a hold on all that, you’ll then need to learn Xcode, which isn’t a language or a programming environment at all, but a very sophisticated development tool (in fact, Xcode is itself an app!), in which you do all your Apple programming. You’re probably now thinking that it’d be easier to write that next Harry Potter novel and are already hunting around for the back of an envelope to start scratching down your ideas, but wait…
I know it sounds disheartening, but there is some good news. After all, it can’t be that hard if so many other people are doing it, right? (Well, actually, yeah it can, there’s a lot of dedicated programming geeks out there!). But look, I’ve been down this road too, and while I haven’t produced any killer apps (still waiting for that great idea…), I have gone from knowing next to nothing about programming to being able to put together an application that does what I tell it to and doesn’t crash my system.
(OK, not entirely true that I didn’t know anything about programming: in the 1980s, I once learned how to get a monochrome computer screen to print “Hello World” in BBC BASIC, which basically involved nothing other than typing >Print “Hello World”; it seemed so ridiculously pointless in 1982 that it turned me off programming for the next thirty years! Other than that, I’m a newbie ).
And the good news gets better: most all of the documentation you need to learn how to be an app developer is available free from Apple. Truly, and I mean this with no trace of irony, it is hugely generous of Apple to put the amount of free material they have online for anyone to use. Want to be a Windows developer? Find your local bookstore and start shelling out one heck of a lot of $$$!! The cynical, of course, will say that Apple only do the giveaway to benefit themselves; others might say that giving away free training justifies their 30% cut.
I think of it as a symbiotic relationship: would-be developers who aren’t in computer science departments or big companies could never afford to buy all the material. Likewise, Apple could never have built an App store with such a huge number and wide variety of programs to Wow! their users if they had only had universities and commercial software developers to rely on. This way, both the little people, that’s me (and — I’m assuming — you), and Apple get to win.
I’ll tell you how to get started in a minute, but before I do let me point out that the ride is not entirely free. There’s probably a point at the beginning and certainly one at the end where you will need to lay out some of your hard-earned. So let’s deal with that now.
What you need
Right off, you’re going to need a Mac computer. Sorry, if you don’t already have one, you’re going to have to buy one; a low-range Macbook Air or Mac Mini will do, anything that can run OS X Lion. You can’t develop Mac apps on your iPhone or iPad, I’m afraid (but it does work the other way too: you don’t need an iPad or iPhone to develop apps for these devices. More on this below).
And what about if you have a good-spec PC? Yes, you could get a Mac emulator (VMmare) or mess around with OSx86, but frankly, these options are likely to cause you more grief than they’re worth; you could end up with apps that don’t build properly, and/or which breach Apple’s licensing conditions.
I’m not saying don’t do it, that’s your choice; I am saying your chances of successfully building an app, making it stable, and getting it accepted into the App store by Apple are significantly reduced if you go that route. Given the price of a basic Mac Mini on Ebay, you could well end up spending more money (as well as time) trying to avoid buying a Mac than just buying a cheap one.
The other expense you might need to lay out for is a basic ‘Intro to C’ book. There’s plenty of web offerings, but really a good ‘idiots’ book like the Dummies or Absolute Beginners should be enough and has the benefit of being reasonably likely to get you to the level of proficiency you need in the shortest amount of time. After that, you learn the rest for free (Objective-C, Cocoa, Xcode) from Apple. At the end of the process, when your app is built and you want to submit your app to the App store, you’ll have to register with Apple for a licence as an app developer and vendor; current cost $99.
Take the first step
“Sign me up”, you say, “where do I start?” The first thing to do is to sign up to Apple’s developer community: this is free (don’t confuse it with the Developer Program or Licensing, which costs $99 and which you don’t need till you’ve built an app you want to upload to the App store).
Once you’re in the Developer Community, download Xcode 4, Apple’s development environment (a different thing from a programming environment, but don’t worry, you’ll get the hang of all this terminology easily enough once you start reading the docs). This is a 4GB monster of a program – bigger than your average operating system, so make sure you have the space – and it is also free. Xcode comes with free iPhone and iPad simulators and in itself, this is a piece of software that’s probably worth a couple of thousand dollars. So smile: you’re already making a profit even though you bought that Mac Mini! This is also the reason why you don’t need, and in fact can’t use, your own iPad or iPhone to test your apps: everything has to be done in Xcode, and this monster app only runs on Mac OS X.
Once you’ve downloaded Xcode, you can play around with it if you want, but unless you’ve worked with an IDE (integrated development environment) before, it’s pretty complicated, so it’s best to wait till you work through the tutorials. It’s not the kind of software you can learn through serendipitous exploration.
Instead, go to the documentation resources and start with the tutorial Your First Mac Application.
By the time you get through this, you’re going to realise why you need to learn Ansi C, Objective-C and Cocoa. So put Xcode away for now, and start on the path of learning to speak Apple’s language. When you get there, just add 1 great idea + 1 great marketing strategy, and you’re on your way to California!
The short guide:
1. Get a Mac
2. Learn C, learn Objective-C, learn Cocoa, learn Xcode
3. Come up with an idea for a great app and plan it out carefully
4. Build and test your app
5. Pay the licensing fee and submit your app to Apple
6. Once it’s been through the review process and accepted, implement your marketing strategy
7. Watch the millions role in and retire.
It’s been over 10 days since the jury went out to weigh up the evidence for and against Mac’s new operating system, 10.7 (OS X Lion). With Apple announcing a million downloads in the first 24 hours, there’s been no shortage of heated debate across the blogosphere and discussion boards (this thread runs to 60 pages and counting! Also see this witty and perceptive post about one user’s frustrations with the upgrade).
So it appears that some love it, others hate it, many are merely sanguine about the whole experience. A number of people are reporting trying it and reverting back to Snow Leopard with brow-mopping relief. My guess, though, is that the vast majority of Snow Leopard users are patiently waiting till a few updates have been released and all the early bugs ironed out.
It’s worth remembering the options: even if you buy Lion now to take advantage of the $30 opening price, you don’t have to install it now. You could buy it and leave the installer app in your Apps folder till the updates get released. Nor do you have to install it over the top of your existing installation. You could install Lion on an external disc instead, or move your Snow Leopard to an external disc and have Lion on your internal disc. Either of those options will allow you to play around with it and switch over fully when you’re truly ready. Don’t forget you can check out whether your existing software will work with Lion.
I have to say though, after ten days, 10.7 is starting to grow on me, and I think the external drive with Snow Leopard sitting on it is going to be gathering dust in a cupboard from now on. That’s not to say I’m thrilled with all that Lion has to offer. It’s a mixed bag, so sit back and let me read the court’s judgement in full.
The Good, …
— yes, I have unwillingly been converted. The four-finger screen swipe (left/right to change screen, up/down for Spaces and Expose, respectively) is addictive, and now I don’t think I could live without it. The truth is I could never get along with Spaces or Expose in Snow Leopard anyway, but Mission Control really does sort of force itself upon you. I do miss the App Switcher that is no longer available via the trackpad (Cmd-Tab still invokes it). There are free 3rd Party programs that you can get to add it back into the trackpad, but my experience is they are awkward at best.
— this is an app I use a lot and I love what they’ve done to it. Preview’s enhancements are one of the most undersold changes in all the talk about Lion. It’s always been ahead of Adobe Reader to my mind, but it did have shortcomings, particularly with adding and placing comments neatly and readably. The new Preview has tidied that up nicely, with the comment markers placeable with much finer precision and clear, neat lines indicating which comment each belongs to. The full screen feature also looks great and makes reading a pleasure.
— is growing on me. Switch it back to Classic view for a tidier interface, but there’s still lots of nice things about it. The animated display when you double-click to open a message is very neat (note: you won’t see the animation if you’ve got your IMAP account settings set to ‘Don’t keep copies of any messages’ in Mail Preferences | Advanced).
the Bad, …
Well, overall, the worst thing about Lion is that most of the good things are really cosmetic. There’s not a lot of new things you can do with Lion, and what there are, I don’t like much, particularly the triumvirate of data guardians otherwise known as
Resume, Autosave and Versions
— Apple has gone to extraordinary lengths to ensure every keystroke, every page, every file you ever open is remembered somewhere (and often in multiple somewheres) on your internal drive and your backup drives. It’s worth noting that not all of these are places the average user can either find or remove. This is something that not everyone is thrilled about, and certainly it’s raised a few eyebrows among the security-conscious. If I were a Chinese blogger, I’m not sure I’d want to update to Lion (you think the Chinese don’t buy Macs? Oh,please!). Another thing worth noting about the Evil Trinity is that Apple has also made them extremely difficult to turn off. Resume, despite what you might be reading elsewhere, cannot be turned off by default (or at least no one’s found a way to do it yet).
However, with all these things, it’s not so much that you can’t beat them, but that you have to work around them. Adjusting your workflow to avoid Resume, Autosave and Versions is certainly possible, but something some may rightly begrudge paying $30 to have to do (in which case, that external backup of Snow Leopard I mentioned above is your friend!). I’ve already written about Resume, and I hope to post workarounds for Versions and Autosave in the near future (sign up for the RSS feed).
The only other ‘bad’ thing I have to say about 10.7 is LaunchPad. This is the iPad look-alike-finger-swiping app display (known as ‘springboard’ on the iPad). A complete waste of time: literally, it’ll take you forever to organise it, and even then it’s a very slow way to find anything but your most familiar apps. There have always been much faster and more efficient ways to get to both your most-oft used apps (the Dock) and those you only occasionally fire up (Finder).
…and the Ugly.
It’s not often that Apple do ugly, but its been universally acknowledged that the designs for iCal, Address Book and Photo Booth are a real eyesore. Fortunately, it’s easy to get rid of them with a bit of mucking about.
So should you upgrade or not? Well, why make it a black-and-white decision when you could have the best of both worlds? If you have a spare drive hanging around, whip it out, pay your $30 and take Lion for a test-drive. If it’s not for you right now, just put it away till the updates smooth it out and the time is right regarding compatibility. After all, if you’ve invested heavily in Apple products or have a lot of legacy material, then it’s probably only a matter of time before you give in and let the Lion tame you, too!
