The iMac 'Core i5' 2.5 21.5-Inch Aluminum (Mid-2011) is powered by a Quad Core 2.5 GHz Intel 'Core i5' I5-2400S (Sandy Bridge) processor with a dedicated 256k level 2 cache for each core and a 6 MB shared level 3 cache. In lieu of a system bus, it has a 'Direct Media Interface' (DMI) that 'connects between the processor and chipset' at 5 GT/s.
By default, it is configured with 4 GB of RAM (1333 MHz PC3-10600 DDR3 SDRAM), a 500 GB (7200 RPM) hard drive, a vertically-mounted slot-loading DVD±R DL 'SuperDrive', and AMD Radeon HD 6750M graphics with 512 MB of dedicated GDDR5 memory.
It also has a built-in 'FaceTime HD' video camera and built-in stereo speakers underneath the 21.5' glossy 16:9 LED-backlit TFT Active Matrix LCD (1920x1080 native) display 'with IPS technology'.
Connectivity includes four USB 2.0 ports, a Firewire '800' port, built-in AirPort Extreme, Gigabit Ethernet, and an SDXC card slot as well as a single 'Thunderbolt' port that is backwards compatible with Mini DisplayPort and, likewise, supports an external display up to 30' (2560x1600). Thunderbolt also supports other peripherals that use the Thunderbolt standard which provides up to 10 Gbps of bandwidth in both directions.
Externally, the 'Mid-2011' iMac line uses the same 'edge-to-edge' glass design and 'seamless all aluminum enclosure' as the 'Mid-2010' models that came before them. Internally, however, the 'Mid-2011' line is equipped with faster processors and faster graphics processors, as well as the aforementioned external improvements of a higher resolution (and wider angle) webcam and Thunderbolt port.
The 'Mid-2011' iMac models included a compact aluminum Apple Wireless Keyboard and the choice of either a multi-touch 'Magic Mouse' or a multi-touch 'Magic Trackpad' that 'enables users to scroll smoothly up and down a page with inertial scrolling, pinch to zoom in and out, rotate an image with their fingertips and swipe three fingers to flip through a collection of web pages or photos' just like on Apple notebooks from the same era. An aluminum remote was offered for an additional US$19, too.

Publisher Description
We understand, you’re busy. You’ve got stuff to do. Work. Home. Play.
The only way you’ll make it through all the things that you need to do is to organize them somehow. Maybe you’ve been making do with notebooks or sticky notes—and hoping they don’t fall into the world of lost things behind your desk. But hey! You’ve got this awesome Mac sitting in front of you. You use it every day.
The new OmniFocus 2 for Mac features everything you need to seriously get stuff done, and the OmniFocus 2 for Mac User Manual is your guide to navigating all of the shiny features in the new OmniFocus. This book provides a detailed overview of every nook and cranny of the app. You’ll discover what’s new in OmniFocus 2, what features are available in OmniFocus 2 Pro, and learn about updates like Perspectives, Forecast, Review, and extensions for the latest versions of macOS.
Yes Virginia, there is a TOC, et.al.
I Mac 12.2 Service Manual Free
The table of contents is accessed from an icon on the book’s window menu bar. Click to select and jump directly to that place. It goes away when focus is put back on the book itself. Maybe a TOC nav pane would be nice.
The manual is well written. Clean, concise, with very understandable explanations. Starting there, given iBook highlighting, notes, links to Omni support documents (web pages), and my creating OmniFocus events for later study I’d say this user manual is quite user friendly and eminently useful.
Useless
No TOC? No Index? Nonsense.
“Oh, but you can just search for whatever you want!”. Really? Only if I can guess what word was used for it. Otherwise, I’m clueless as to where it might appear in the book.
Just because we’ve liberated certain content from the tyranny of paper doesn’t mean we need to throw the baby out with the bathwater. Give me ALL the reasonably available search tools, not just the “modern” ones. Is that so hard?
