It's the folder where iTunes saves the backUps of your iDevice. And it takes so much space because each time you sync a device, previous backUps are not deleted. Deleting the folder will, then, mean losing those backUps. Doing this regularly is advised for saving HD space. Just make sure to make a new backUp afterwards, and that you won't need those ...

Carbon Copy Cloner should do the job. CCC (Carbon Copy Cloner) creates a bootable backup, and preserves all your files, and in the right hierarchy. You can also have incremental backups (it only backs up items that have changed since the last backup). You can schedule CCC to backup regularly. CCC also has the ability to backup over a network. I also like the ...

There's no difference besides the storage capacity. As the iPhone does not have an option to extend the memory after purchase, you have to choose the right amount of storage right from the beginning. You can always manage how much space you use by manually choosing which data to sync (music, photos, movies, apps). Generally more available space gives you ...

swapfile0, swapfile1 and so on are swap files. You can sort of think of them like "backup" RAM. When your computer doesn't have enough RAM to accomodate the memory requests of all your programs (which is almost always, this is normal), it uses these files to "write out" part of what it had in RAM. The sleepimage has a very similar use, except it's used only ...

Shirt Pocket's SuperDuper is a nice app, but it is pricey. $28, free trial available. One of its good features: It allows you to perform an incremental backup that only updates what's changed.

Other than cost (for the initial purchase and potentially to repair or replace it) and size, there is no measurable difference in performance, battery life or other function between any of the iPhone 5 models for sale (and certainly within the same carrier in case one LTE model uses slightly more power than another). The same goes for each iPhone (and iPad ...

There is a bug in Pages. When you export a file in ".doc" or ".docx" format it embeds 489KB PNG files (a single one in a docx file, three in a doc file). These files are intended to be used as the background fill on default shapes, but they are present whether they are used or not. I documented the bug here. And reported it to Apple as rdar://17089255. At ...

The specs page for the iPod Classic says "hard drive". That's a mechanical drive with a set of spinning platters and read/write heads. And here's a replacement part for the drive in the unit. The compatibility list on that page lists: iPod 6th Gen 160GB iPod 7th Gen 160GB And here's a video that gives some details on the Samsung drive in the unit: ...

The difference is 16GB of storage. How big is your iTunes library? Do you want to carry movies and TV shows on your phone in case you happen to want to watch them while waiting somewhere? How big are the last 1000 photos you've taken in your iPhoto library? Do you like to shoot video with your phone? Then, what about apps? Some apps are much larger than ...

The exact answer will vary by device, because there are separate iOS builds for each one. The easiest way to figure this out is to examine an iOS 6 install image (a .ipsw file). The iPad 3 (Wi-Fi only) is the iOS device that is most similar to a Microsoft Surface, although the two are still very different. The iOS 6.0 (build 10A403) install image weighs in ...

Quit iTunes. Then you can go into your "~/Music/iTunes/Mobile\ Applications/" directory, and manually delete apps using the Terminal or Finder. Before the next Sync, in iTunes control-click to hit the "Reset Warnings" menu item for your device. During the next Sync, iTunes may ask if you want to (re)copy purchased files from the device. Just say no. ...

Carbon Copy Cloner (CCC) hands down. Even Apple enterprise recommends it, and they use it for their live servers. Although SuperDuper! is fine for standard Mac OS, it is not recommended by the general population for the Server OS. The latest CCC adds great features too. Use the $30 you would spend on SuperDuper! And donate it to CCC. It's what we use in the ...

My setup is the following : Macbook pro 2009, 13" SSD (Intel X25M Postville) replacing the superdrive, used as system + home folder disk Factory HDD used for music and pictures storage I tried to move my home folder to te HDD, here are my conclusions : when you move your entire home folder to an HDD, your mac boots fast, but you don't get too much ...

First you should figure out whether or not compression is worth it. This depends largely on the type of content you're storing. If the content is not compressible (JPEG images, most video formats, ZIP archives, etc.), there's little benefit and the added overhead of decompression may even cause a (minor) slowdown in file access. HFS+ compression is most ...

The tools are in the terminal app: fs_usage shows the io on a per file instance and grep will help you filter results to one app if desired. vm_stat 10 shows aggregate swap activity every 10 seconds - you can fiddle with the timing based on how close you care to look If you want a nice graph and full monitor, check out Instruments in Xcode. It has ...

Moving the Home Directory to the SSD Macintosh Performance Guide has an excellent writeup on the subject. Most important perhaps is the admonishion to Create another admin account that resides on the boot drive. Else, if your drive containing the home directory goes away, you cannot log in. Tips on how full or empty to keep your boot drive and any ...

On iTunes itself, on the App section of your Library (top section in the left side navigation bar) you can see how big Apps are by switching to List view (iTunes menu bar -> View -> As List).

Yes. You need the discontinued "iPod" camera connector. (not to be confused with the iOS iPad camera connector) http://support.apple.com/kb/TA38187 They are for sale on Amazon (and of course at local thrift shops and electronics shops worldwide). http://www.amazon.com/Apple-Camera-Connector-iPod-White/dp/B000KIRGF4

For installation of the OS, apps et cetera Give one disk to JHFS+. If you're limited to two disks and one is hard, use the hard disk. For integrity of user data Give at least one other disk to ZFS. Why not HFS Plus? A little HFS test – a command-line presentation by @jolly of DIY Fusion Drive fame – demonstrates HFS Plus failure in one situation. ...

Yes! You can change the volume from a removable device to a fixed disk by flipping the removable bit. Lexar made an application for Windows called 'Lexar BootIt', a well known application for this task. I found a solution involving DD, but I have not tested it and I'd severely recommend backing up your card before doing anything with DD/Terminal. I created ...

First question: yes, iCloud backs up your photo as it is. If you delete media from your photos library it will be deleted from iCloud. (I might add that videos are also stored in the cloud - and consequently take up the most room). Second question: It is possible you can use the Scanner and Camera wizard to import photos from your iPhone. Here is are two ...

Yes, it won't hurt the iMac. In fact they can even be used sideways, as long as you don't block any vents. Hard drive bearings are said to last longest when they are either upright or flat, but apart from the convection-cooled Mac Cube I don't know of any Mac that depends on orientation for cooling or anything else. If you are putting them away for any ...

A few thoughts come to mind. Firstly, this is all dependent on what sort of software solution you're using to store your photos. If it's just files in folders, that makes things simpler, and is pretty platform agnostic. But if you're using (or want to use) some sort of organization software, then that obviously complicates things, both in terms of platforms ...

I own a botique short-run book publishing company. For all intents, the design and printing operations are a one-man operation. Time spent waiting for a spinning beach ball is wasted and unprofitable time. Funds are tight for getting the latest equipment, but I try to incorporate the technology that provides the best bang for the buck. I recreationally ...

You have to take into account that the exact number is an approximated value and that the device needs additional space to install the application. I’m guessing that although the application says it’s 643Mb, it really uses some more when it gets installed. You’re really pushing the limits of your iOS there :)

Due to the way items are synced to the iPod and iPhone, you need a bit more space than the size of the app. So although the app may only take up 643MB, you'll actually need more to sync it.

I don't know the answer to your question in general, but as far as RAGE HD goes (all numbers on my Mac): Size shown in Finder: 779.7 MB Size shown in iTunes (Library > Apps): 743.6 MB Size needed to install on my iPad (Devices > my iPad > Apps): 1.18 GB                             ...

Those are part of the virtual memory system: swapfile* contains literally swap data, which is memory content that has been pushed out to disk. The sleepimage is used for suspend and resume support; when the system hibernates, that is where the memory data is stored. Deleting either would cause significant problems: sleepimage is the same size as RAM, and ...

There is a folder, located at ~/Library/Mobile Documents/, that iCloud-enabled apps store their data in. You can trickily use this folder by simply putting any files in there that you want to access from another iCloud-enabled computer. Unfortunately, there's no way to access this folder via the web or on an iOS device, but Macs synced to the same iCloud ...

Having Time Machine active is probably the cause for the difference between the two reported sizes. For example: Finder tells me I currently have 55.53GB of freespace on my SSD. System Information tells me there's 44.22GB. System Information also tells me 11.31GB are being used for Backups. 44.22GB + 11.31GB = 55.53GB In Lion, Time Machine will keep ...
