Step 2: Uninstall Ymacco Trojan and related software from Windows Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. During the installation of OS, the macOS installer will automatically decide whether to use APFS or Mac OS Extended for the disk. You can also use the FAT32 format on Mac for USB drives if you wish to use it on both Mac and Windows. The FAT32 format can be read and written on both OS and hence it is the most versatile format for use.

App Sandbox is an access control technology provided in macOS, enforced at the kernel level. It is designed to contain damage to the system and the user’s data if an app becomes compromised. Apps distributed through the Mac App Store must adopt App Sandbox. Apps signed and distributed outside of the Mac App Store with Developer ID can (and in most cases should) use App Sandbox as well.

At a Glance

Complex systems will always have vulnerabilities, and software complexity only increases over time. No matter how carefully you adopt secure coding practices and guard against bugs, attackers only need to get through your defenses once to succeed. While App Sandbox doesn’t prevent attacks against your app, it does minimize the harm a successful one can cause.

A non-sandboxed app has the full rights of the user who is running that app, and can access any resources that the user can access. If that app or any framework it is linked against contain security holes, an attacker can potentially exploit those holes to take control of that app, and in doing so, the attacker gains the ability to do anything that the user can do.

Designed to mitigate this problem, the App Sandbox strategy is twofold:

  1. App Sandbox enables you to describe how your app interacts with the system. The system then grants your app the access it needs to get its job done, and no more.

  2. App Sandbox allows the user to transparently grant your app additional access by way of Open and Save dialogs, drag and drop, and other familiar user interactions.

App Sandbox is not a silver bullet. Apps can still be compromised, and a compromised app can still do damage. But the scope of potential damage is severely limited when an app is restricted to the minimum set of privileges it needs to get its job done.

App Sandbox is Based on a Few Straightforward Principles

By limiting access to sensitive resources on a per-app basis, App Sandbox provides a last line of defense against the theft, corruption, or deletion of user data, or the hijacking of system hardware, if an attacker successfully exploits security holes in your app. For example, a sandboxed app must explicitly state its intent to use any of the following resources using entitlements:

  • Hardware (Camera, Microphone, USB, Printer)

  • Network Connections (Inbound or Outbound)

  • App Data (Calendar, Location, Contacts)

  • User Files (Downloads, Pictures, Music, Movies, User Selected Files)

Access to any resource not explicitly requested in the project definition is rejected by the system at run time. If you are writing a sketch app, for example, and you know your app will never need access to the microphone, you simply don’t ask for access, and the system knows to reject any attempt your (perhaps compromised) app makes to use it.

On the other hand, a sandboxed app has access to the specific resources you request, allows users to expand the sandbox by performing typical actions in the usual way (such as drag and drop), and can automatically perform many additional actions deemed safe, including:

  • Invoking Services from the Services menu

  • Reading most world readable system files

  • Opening files chosen by the user

The elements of App Sandbox are entitlements, container directories, user-determined permissions, privilege separation, and kernel enforcement. Working together, these prevent an app from accessing more of the system than is necessary to get its job done.

Design Your Apps with App Sandbox in Mind

After you understand the basics, look at your app in light of this security technology. First, determine if your app is suitable for sandboxing. (Most apps are.) Then resolve any API incompatibilities and determine which entitlements you need. Finally, consider applying privilege separation to maximize the defensive value of App Sandbox.

Xcode Helps You Migrate an Existing App to App Sandbox

Some file system locations that your app uses are different when you adopt App Sandbox. In particular, you gain a container directory to be used for app support files, databases, caches, and other files apart from user documents. Xcode and macOS support migration of files from their legacy locations to your container.

Preflight Your App Before Distribution

After you have adopted App Sandbox in your app, as a last step each time you distribute it, double check that you are following best practices.

How to Use This Document

To get up and running with App Sandbox, perform the tutorial in App Sandbox Quick Start. Before sandboxing an app you intend to distribute, be sure you understand App Sandbox in Depth. When you’re ready to start sandboxing a new app, or to convert an existing app to adopt App Sandbox, read Designing for App Sandbox. If you’re providing a new, sandboxed version of your app to users already running a version that is not sandboxed, read Migrating an App to a Sandbox. Finally, before distributing your app, work through the App Sandbox Checklist to verify that you are following best practices for App Sandbox.

Prerequisites

Before you read this document, make sure you understand the overall macOS development process by reading Mac App Programming Guide. Factorio 0 17 79 download free.

To complement the damage containment provided by App Sandbox, you must provide a first line of defense by adopting secure coding practices throughout your app. To learn how, read Security Overview and Secure Coding Guide.

An important step in adopting App Sandbox is requesting entitlements for your app. For details on all the available entitlements, see Entitlement Key Reference.

You can enhance the benefits of App Sandbox in a full-featured app by implementing privilege separation. You do this using XPC, a macOS implementation of interprocess communication. To learn the details of using XPC, read Daemons and Services Programming Guide.

In October 2018, Nuance announced that it has discontinued Dragon Professional Individual for Mac and will support it for only 90 days from activation in the US or 180 days in the rest of the world. The continuous speech-to-text software was widely considered to be the gold standard for speech recognition, and Nuance continues to develop and sell the Windows versions of Dragon Home, Dragon Professional Individual, and various profession-specific solutions.

This move is a blow to professional users—such as doctors, lawyers, and law enforcement—who depended on Dragon for dictating to their Macs, but the community most significantly affected are those who can control their Macs only with their voices.

What about Apple’s built-in accessibility solutions? macOS does support voice dictation, although my experience is that it’s not even as good as dictation in iOS, much less Dragon Professional Individual. Some level of voice control of the Mac is also available via Dictation Commands, but again, it’s not as powerful as what was available from Dragon Professional Individual.

TidBITS reader Todd Scheresky is a software engineer who relies on Dragon Professional Individual for his work because he’s a quadriplegic and has no use of his arms. He has suggested several ways that Apple needs to improve macOS speech recognition to make it a viable alternative to Dragon Professional Individual: Can i install revit on mac.

  • Support for user-added custom words: Every profession has its own terminology and jargon, which is part of why there are legal, medical, and law enforcement versions of Dragon for Windows. Scheresky isn’t asking Apple to provide such custom vocabularies, but he needs to be able to add custom words to the vocabulary to carry out his work.
  • Support for speaker-dependent continuous speech recognition: Currently, macOS’s speech recognition is speaker-independent, which means that it works pretty well for everyone. But Scheresky believes it needs to become speaker-dependent, so it can learn from your corrections to improve recognition accuracy. Also, Apple’s speech recognition isn’t continuous—it works for only a few minutes before stopping and needing to be reinvoked.
  • Support for cursor positioning and mouse button events: Although Scheresky acknowledges that macOS’s Dictation Commands are pretty good and provide decent support for text cursor positioning, macOS has nothing like Nuance’s MouseGrid, which divides the screen into a 3-by-3 grid and enables the user to zoom in to a grid coordinate, then displaying another 3-by-3 grid to continue zooming. Nor does Apple have anything like Nuance’s mouse commands for moving and clicking the mouse pointer.

When Scheresky complained to Apple’s accessibility team about macOS’s limitations, they suggested the Switch Control feature, which enables users to move the pointer (along with other actions) by clicking a switch. He talks about this in a video.

Unfortunately, although Switch Control would let Scheresky control a Mac using a sip-and-puff switch or a head switch, such solutions would be both far slower than voice and a literal pain in the neck. There are some better alternatives for mouse pointer positioning:

Mac
  • Dedicated software, in the form of a $35 app called iTracker.
  • An off-the-shelf hack using Keyboard Maestro and Automator.
  • An expensive head-mounted pointing device, although the SmartNav is $600 and the HeadMouse Nano and TrackerPro are both about $1000. It’s also not clear how well they interface with current versions of macOS.

Regardless, if Apple enhanced macOS’s voice recognition in the ways Scheresky suggests, it would become significantly more useful and would give users with physical limitations significantly more control over their Macs… and their lives. If you’d like to help, Scheresky suggests submitting feature request feedback to Apple with text along the following lines (feel free to copy and paste it):

Because Nuance has discontinued Dragon Professional Individual for Mac, it is becoming difficult for disabled users to use the Mac. Please enhance macOS speech recognition to support user-added custom words, speaker-dependent continuous speech recognition that learns from user corrections to improve accuracy, and cursor positioning and mouse button events.
