OS X’s Firewalls. All versions of OS X through 10.4 (Tiger) have included a Unix-based firewall called ipfw. In security parlance, ipfw is a packet-filtering firewall: it checks each packet. Sep 27, 2016 Advanced Mac users may wish to allow a third option, which is the ability to open and allow apps downloaded from anywhere in MacOS Catalina, macOS Sierra, macOS High Sierra, and MacOS Mojave. To be clear, the “Allow applications downloaded from anywhere” option is hidden by default in Gatekeeper for macOS from Sierra onward. Oct 07, 2019 If you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app can't be opened because it was not downloaded from the App Store. If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an. MacOS Sierra changed the way your Mac handles applications from unidentified developers. It's now stricter with installing such apps than previous versions of OS X, but there are ways to get.

As of MacOS 10.9, signed packages are required by default. Apple charges for this capability, and requires use of their tooling to do it. For the time being, MacOS users may need to disable signed package checking for CHIRP. Instructions provided by Jim, K2SON:
Alternately, you can disable them for your entire system, although this has security implications that should not be ignored. Instructions for this provided by Tom, KD7LXL:
As of 10.12 (Sierra) the UI for disabling app security was removed. The functionality is still there, but must be enabled from the command line.

Unfortunately, Apple has made significant changes in 10.15 which cause major issues for independent software developers. CHIRP is significantly impacted and the future is unclear.
At the very least, Catalina users should use the 'unified' build of the app provided on the download page, which uses the system's 64-bit python runtime. Also note that there are significant limitations on what files unsigned applications can access which makes it very difficult to open, save, find, and otherwise organize image and CSV files with chirp. Please see issue #7147 for the current information about workarounds.
USB to serial cables are not merely wire, they contain small computer circuits at one end of the cable that respond as a USB device and convert the data to serial. These cables are not all the same, so the computer needs a software 'driver' so it can recognize the cable and speak to it correctly. You will need to install one of these 5 below.
FTDI cables¶
Note that with Mac OSX 10.9 'Mavericks', Apple provides their own driver for FTDI chipset. You may need to remove the OEM FTDI driver and use only the Apple FTDI driver, or you may need to disable the Apple FTDI driver and install the OEM FTDI drivers. YMMV.

WinChipHead CH340 series chipset¶
The WinChipHead CH340 series chipset is not compatible with the Prolific 2303 drivers. This chipset will report a Product ID of 0x7523 and a Vendor ID of 0x1a86. A signed driver compatible with Yosemite is available from http://blog.sengotta.net/signed-mac-os-driver-for-winchiphead-ch340-serial-bridge/ as the driver offered on the manufacturer's website (in Chinese) is not signed and requires allowing unsigned kernel extensions, which is a significant security risk on OS X.
You can verify that the drivers are installed & working by connecting the USB cable to your Mac, then running “System Profiler”, or “System Information” (found in /Applications/Utilities ). When the USB cable is connected and drivers correctly installed, the cable will show up in the USB section of the System Profiler.
Another way to see that the driver is correctly installed is to open Terminal and type:

OS X incorporates the latest technologies for creating powerful and fun-to-use apps. But the technologies by themselves are not enough to make every app great. What sets an app apart from its peers is how it helps the user achieve some tangible goal. After all, users are not going to care what technologies an app uses, as long as it helps them do what they need to do. An app that gets in the user’s way is going to be forgotten, but one that makes work (or play) easier and more fun is going to be remembered.
You use Cocoa to write apps for OS X. Cocoa gives you access to all of the features of OS X and allows you to integrate your app cleanly with the rest of the system. This chapter covers the key parts of OS X that help you create great apps. In particular, this chapter describes some of the important ease-of-use technologies introduced in OS X v10.7. For a more thorough list of technologies available in OS X, see Mac Technology Overview.
An Environment Designed for Ease of Use
OS X strives to provide an environment that is transparent to users and as easy to use as possible. By making hard tasks simple and getting out of the way, the system makes it easier for the user to be creative and spend less time worrying about the steps needed to make the computer work. Of course, simplifying tasks means your app has to do more of the work, but OS X provides help in that respect too.
As you design your app, you should think about the tasks that users normally perform and find ways to make them easier. OS X supports powerful ease-of-use features and design principles. For example:
All of the preceding features are supported by Cocoa and can be incorporated with relatively little effort.
A Sophisticated Graphics Environment
High-quality graphics and animation make your app look great and can convey a lot of information to the user. Animations in particular are a great way to provide feedback about changes to your user interface. So as you design your app, keep the following ideas in mind:
For information about the graphics technologies available in OS X, see Media Layer in Mac Technology Overview.
Low-Level Details of the Runtime Environment
When you are ready to begin writing actual code, there are a lot of technologies available to make your life easier. OS X supports all of the basic features such as memory management, file management, networking, and concurrency that you need to write your code. In some cases, though, OS X also provides more sophisticated services (or specific coding conventions) that, when followed, can make writing your code even easier. Mac battery tester app.
Based on UNIX
OS X is powered by a 64-bit Mach kernel, which manages processor resources, memory, and other low-level behaviors. On top of the kernel sits a modified version of the Berkeley Software Distribution (BSD) operating system, which provides interfaces that apps can use to interact with the lower-level system. This combination of Mach and BSD provides the following system-level support for your apps:

For detailed information about the underlying environment of OS X, see Kernel and Device Drivers Layer in Mac Technology Overview. https://occlever596.weebly.com/blog/download-latest-skype-version-for-mac.
Concurrency and Threading
Each process starts off with a single thread of execution and can create more threads as needed. Although you can create threads directly using POSIX and other higher-level interfaces, for most types of work it is better to create them indirectly using block objects with Grand Central Dispatch (GCD) or operation objects, a Cocoa concurrency technology implemented by the
NSOperation class.
GCD and operation objects are an alternative to raw threads that simplify or eliminate many of the problems normally associated with threaded programming, such as synchronization and locking. Specifically, they define an asynchronous programming model in which you specify only the work to be performed and the order in which you want it performed. The system then handles the tedious work required to schedule the necessary threads and execute your tasks as efficiently as possible on the current hardware. You should not use GCD or operations for work requiring time-sensitive data processing (such as audio or video playback), but you can use them for most other types of tasks.
For more information on using GCD and operation objects to implement concurrency in your apps, see Concurrency Programming Guide.
The File System
The file system in OS X is structured to provide a better experience for users. Rather than exposing the entire file system to the user, the Finder hides any files and directories that an average user should not need to use, such as the contents of low-level UNIX directories. This is done to provide a simpler interface for the end user (and only in places like the Finder and the open and save panels). Apps can still access any files and directories for which they have valid permissions, regardless of whether they are hidden by the Finder.
When creating apps, you should understand and follow the conventions associated with the OS X file system. Knowing where to put files and how to get information out of the file system ensures a better user experience.
A Few Important App Directories
The OS X file system is organized in a way that groups related files and data together in specific places. Every file in the file system has its place and apps need to know where to put the files they create. This is especially important if you are distributing your app through the App Store, which expects you to put your app’s data files in specific directories.
Table 1-1 lists the directories with which apps commonly interact. Some of these directories are inside the home directory, which is either the user’s home directory or, if the app adopts App Sandbox, the app’s container directory as described in App Sandbox and XPC. Because the actual paths can differ based on these conditions, use the
URLsForDirectory:inDomains: method of the NSFileManager class to retrieve the actual directory path. You can then add any custom directory and filename information to the returned URL object to complete the path.
Listing 1-1 shows an example of how to retrieve the base path to the
Application Support directory and then append a custom app directory to it.
Listing 1-1 Getting the path to the
Application Support directory
For more information about how to access files in well known system directories, see File System Programming Guide.
Mac Osx Allow Blocked App General Security SystemCoordinating File Access with Other Processes
In OS X, other processes may have access to the same files that your app does. Therefore, when working with files, you should use the file coordination interfaces introduced in OS X v10.7 to be notified when other processes (including the Finder) attempt to read or modify files your app is currently using. For example, coordinating file access is critical when your app adopts iCloud storage.
The file coordination APIs allow you to assert ownership over files and directories that your app cares about. Any time another process attempts to touch one of those items, your app is given a chance to respond. For example, when an app attempts to read the contents of a document your app is editing, you can write unsaved changes to disk before the other process is allowed to do its reading.
Using iCloud document storage, for example, you must incorporate file coordination because multiple apps can access your document files in iCloud. The simplest way to incorporate file coordination into your app is to use the
NSDocument class, which handles all of the file-related management for you. See Document-Based App Programming Guide for Mac.
On the other hand, if you're writing a library-style (or “shoebox”) app, you must use the file coordination interfaces directly, as described in File System Programming Guide.
Interacting with the File System
Disks in Macintosh computers are formatted using the HFS+ file system by default. However, Macintosh computers can interact with disks that use other formats so you should never code specifically to any one file system. Table 1-2 lists some of the basic file system attributes you may need to consider in your app and how you should handle them.
File-System Usage Requirements for the Mac App Store
To promote a more consistent user experience, applications submitted to the Mac App Store must follow certain rules about where they write files. Users can be confused when applications cause unexpected side effects on the file system (for example, storing databases in the user’s Documents folder, storing files in the user’s Library folder that are not recognizably associated with your application, storing user data in the user’s Library folder, and so on).
Your application must adhere to the following requirements:
Security
The security technologies in OS X help you safeguard sensitive data created or managed by your app, and help minimize damage caused by successful attacks from hostile code. These technologies impact how your app interacts with system resources and the file system.
App Sandbox and XPC
You secure your app against attack from malware by following the practices recommended in Secure Coding Guide. But an attacker needs only to find a single hole in your defenses, or in any of the frameworks and libraries that you link against, to gain control of your app along with all of its privileges.
Adobe illustrator 23.0 download mac. App Sandbox provides a last line of defense against stolen, corrupted, or deleted user data if malicious code exploits your app. App Sandbox also minimizes the damage from coding errors. Its strategy is twofold:
You describe your app’s interaction with the system by way of setting entitlements in Xcode. An entitlement is a key-value pair, defined in a property list file, that confers a specific capability or security permission to a target. For example, there are entitlement keys to indicate that your app needs access to the camera, the network, and user data such as the Address Book. For details on all the entitlements available in OS X, see Entitlement Key Reference.
When you adopt App Sandbox, the system provides a special directory for use by your app—and only by your app—called a container. Your app has unfettered read/write access to the container. All OS X path-finding APIs, above the POSIX layer, are relative to the container instead of to the user’s home directory. Other sandboxed apps have no access to your app’s container, as described further in Code Signing.
![]()
iOS Note: Because it is not for user documents, an OS X container differs from an iOS container which, in iOS, is the one and only location for user documents. As the sole local location for user documents, an iOS container is usually known simply as an app’s Documents directory.
In addition, an iOS container contains the app itself. This is not so in OS X.
iCloud Note: Apple’s iCloud technology, as described in iCloud Storage, uses the name “container” as well. There is no functional connection between an iCloud container and an App Sandbox container.
Your sandboxed app can access paths outside of its container in the following three ways:
The OS X security technology that interacts with the user to expand your sandbox is called Powerbox. Powerbox has no API. Your app uses Powerbox transparently when, for example, you use the
NSOpenPanel and NSSavePanel classes, or when the user employs drag and drop with your app.
Some app operations are more likely to be targets of malicious exploitation. Examples are the parsing of data received over a network, and the decoding of video frames. By using XPC, you can improve the effectiveness of the damage containment offered by App Sandbox by separating such potentially dangerous activities into their own address spaces.
XPC is an OS X interprocess communication technology that complements App Sandbox by enabling privilege separation. Privilege separation, in turn, is a development strategy in which you divide an app into pieces according to the system resource access that each piece needs. The component pieces that you create are called XPC services. For details on adopting XPC, see Daemons and Services Programming Guide.
For a complete explanation of App Sandbox and how to use it, read App Sandbox Design Guide.
Code Signing
OS X employs the security technology known as code signing to allow you to certify that your app was indeed created by you. After an app is code signed, the system can detect any change to the app—whether the change is introduced accidentally or by malicious code. Various security technologies, including App Sandbox and parental controls, depend on code signing.
In most cases, you can rely on Xcode’s automatic code signing, which requires only that you specify a code signing identity in the build settings for your project. The steps to take are described in Code Signing Your App in Tools Workflow Guide for Mac. If you need to incorporate code signing into an automated build system, or if you link your app against third-party frameworks, refer to the procedures described in Code Signing Guide.
When you adopt App Sandbox, you must code sign your app. This is because entitlements (including the special entitlement that enables App Sandbox) are built into an app’s code signature.
Mac Osx Allow Blocked App General Security System
OS X enforces a tie between an app’s container and the app’s code signature. This important security feature ensures that no other sandboxed app can access your container. The mechanism works as follows: After the system creates a container for an app, each time an app with the same bundle ID launches, the system checks that the app’s code signature matches a code signature expected by the container. If the system detects a mismatch, it prevents the app from launching.
For a complete explanation of code signing in the context of App Sandbox, read App Sandbox in Depth in App Sandbox Design Guide.
The Keychain
A keychain is a secure, encrypted container for storing a user’s passwords and other secrets. It is designed to help a user manage their multiple logins, each with its own ID and password. You should always use keychain to store sensitive credentials for your app.
