The Apple MacBook Air 'Core i5' 1.7 11' (Mid-2012/USB 3.0) features a 22-nm 'Ivy Bridge' 1.7 GHz Intel 'Core i5' processor (3317U) with two independent processor 'cores' on a single chip, a 3 MB shared level 3 cache, 4 GB of onboard 1600 MHz DDR3L SDRAM (which cannot be upgraded after purchase), 64 GB or 128 GB of flash storage, and an 'integrated' Intel HD Graphics 4000 graphics processor that shares system memory.
This all is packed in a razor thin (0.11-0.68 inch), 2.3 pound, aluminum case with an integrated 720p 'FaceTime HD' webcam, a backlit full-size keyboard and an 11.6' widescreen TFT LED backlit active-matrix 'glossy' display (1366x768 native resolution).
Connectivity includes 802.11a/b/g/n Wi-Fi, Bluetooth 4.0, analog audio out, a 'Thunderbolt' port, and two USB 3.0 ports. It lacks internal Ethernet, although an external Thunderbolt adapter was offered as a US$29 option.
Compared to its predecessor, this model has a very similar external enclosure, although it includes the aforementioned USB 3.0 ports and a new thinner and wider 'MagSafe 2' power connector. Internally, however, it has a faster processor, architecture, graphics, RAM, and storage.

The latest macOS released by Apple is the Mac OS Catalina. It is the sixteenth release from them. It was released on the 7th of October in 2019. It has succeeded macOS Mojave and is preceded by the upcoming macOS Big Sur. Catalina is unique as it is the first Mac OS so far that supports only 64-bit applications(32-bit applications are not supported on this operating system at all).

The macOS Catalina 10.15 was extensively praised for its dedication to the user’s security which is something that is of paramount importance and often overlooked in favor of other features. The introduction of many new system features and applications were greatly enjoyed by users. The ability for Mac users to now work with both their Mac and iPad simultaneously was seen as of the greatest additions.

Despite some great improvements, there were also certain difficulties faced and complaints raised by users. The decision to allow Mac Os Catalina and Mac OS sierra to only run 64-bit applications was not seen favorably by many who could not run their 32-bit applications on it. Although the security additions were excellent, many users found the security system irritating to use.

Whenever the user wanted to provide access to any piece of data, macOS Catalina would ask them to grant permission each and every time. Although this was done for the user’s good, it was found to be aggravating at times.

Mac Os Catalina Macbook Air 2012 Specs

Productive Features of Mac OS Catalina 10.15

Take a look at the interesting features that have been introduced and the pre-existing ones that have been reworked in macOS Catalina 10.15:

Catalyst

This is a new feature that has been added in order to make it easier for users to port their iOS apps to their Mac. These are some of the apps that can be used through Catalyst:

MakePass

This is a very efficient pass editor that has been released by Apple. The user can now create barcodes that can be added to the wallet on their phone. These passes can then be customized and used according to the wish of the user.

Dice by PCalc

If you ever need a pair of dice but don’t have one on hand, you can always use Dice by PCalc. This is a highly tested physics-based dice throwing app that can be tried out whenever users are playing a board game. You never need to worry about the dice rolling away with this app and can have a fantastic time throwing some virtual ones.

HabitMinder

HabitMinder is a sort of lifestyle app that will remind users of certain daily activities that they have to do in order to keep themselves healthy. There are a variety of options that can be chosen and the user will be able to monitor themselves and track their progress with their app. Be it exercising, drinking water, or reading, you will be able to keep your tendency to not meet your goals in check using this app.

Fiery Feeds

This is an excellent feed reader that will allow users to be able to customize and enjoy their feeds according to their preferences. Be it the size, font or color of the text, they can all be easily customized using this app.

Countdowns

This is fantastic for those who tend to forget important dates or events in their life. This app will count down to these dates and remind the user of them so that they do not forget.

Pine

If you are looking for some physical and mental relaxation, Pine is the app for you. It offers a bunch of breathing exercises that can help the user sit back and fill themselves up with the energy that they need. Quotes are also shared after each exercise so that the user is motivated to face their day with a renewed sense of purpose.

Crew

The crew is a superb app that can be used for improved team communication. Team leaders and members can send each other messages as well as schedule and assign work to each other.

Zoho Books

If you are terrible at keeping track of your financial records, Zoho Books will definitely be of great help to you. Your transactions will be properly recorded and all your income information will also be stored and updated.

The Communication Limits feature will help users control who their children can communicate with throughout the day. The Notifications app will help users keep count of the number of notifications that they receive from each app that they have. There is even a feature called Pickups that will alert the users of how many times they have picked up their Mac.

Syncing from Mac to other Apple devices

The user’s Mac can now be synced with the other Mac devices that they possess. A high-quality cable should be used to link the two devices together so that syncing can take place. After this is done, Finder window should be opened on the Mac.

The appropriate device can then be chosen under the Locations tab. When this is successfully finished, the user will be able to sync their books, photos, music, movies, television shows, files and even audiobook with the device of their choice.

Sidecar

This has been one of the most popular and highly praised features of the macOS Catalina. Users can operate their Mac and iPad in tandem with each other. The user can start a particular piece of work on their Mac and then resume it on their iPad. The user should ensure that both macOS Catalina on their Mac and iPadOS on their iPad is running before they start doing this.

AirPlay will have to be switched on so that their devices can be connected. Pictures on the Mac can be dragged to the iPad using the mouse and they can then be edited and altered there using an Apple Pencil.

Voice Control

Users will now be able to control their Mac using just their voice. This nifty feature can be used by those who may not want to use the keyboard or mouse to operate on their Mac or those who are just looking to have a fun time seeing their Mac respond to their voice. The Voice Control feature can be simply turned on using Siri or it can be accessed under the System Preference’s Accessibility tab.

Gatekeeper

Air

Although Gatekeeper is an app that has been around on the macOS for a long time, it’s security protection mechanisms have gotten much stricter than before. This security app used to only check new apps that were to be downloaded once. Now, apps are checked at each and every level which means that users can be rest assured that nothing dangerous will get past Gatekeeper. At the same time, many people are not fans of this as it can be exasperating to have to wait for their apps to get checked like this every time. Thus, some people prefer to disable certain parts of Gatekeeper so that they can save time when new apps are being downloaded.
