Safari extensions add functionality to Safari, so you can explore the web the way you want. Extensions can show helpful information about a webpage, display news headlines, help you use your favorite services, change the appearance of webpages, and much more. Extensions are a great way to personalize your browsing experience.
Use the App Store to conveniently download and install Safari extensions. All extensions in the App Store are reviewed, signed, and hosted by Apple for your security.
You can search the Mac App Store for apps supporting a specific extension type. For example, searching for appex:com.apple.share-services will show apps that support the share extension. Not all macOS apps are distributed through the Mac App Store, so this isn't an exhaustive list. Common Mac Extension. I run Mac guests exclusively. That ran fine for a few years but Yosemite and later versions were virtually unusable in a VM. Then, Parallels released Parallels Desktop Lite in the Mac App Store, using the hypervisor instead of kernel extensions. I was just blown away by how much faster it is. And it is free, because I only run Mac VMs.
Start by installing the latest macOS updates to make sure that Safari is up to date. You need Safari 12 or later to get Safari extensions from the App Store.
This shows all running apps, and lets you force-quit them if necessary - just highlight the app and click Force Quit. It's not possible to jump to open apps from this menu, only to close them.
Find and install an extension:
Then return to Safari to turn on the extension you installed:
All extensions installed from the App Store are automatically kept up to date.
Choose Safari > Preferences, then click Extensions.
Safari no longer supports most web plug-ins. To load webpages more quickly, save energy, and strengthen security, Safari is optimized for content that uses the HTML5 web standard, which doesn't require a plug-in. To enhance and customize your browsing experience, use Safari extensions instead of web plug-ins.
Postgres.app is a full-featured PostgreSQL installation packaged as a standard Mac app.It includes everything you need to get started:we’ve even included popular extensions like PostGIS for geo data and plv8 for JavaScript.
Postgres.app has a beautiful user interface and a convenient menu bar item.You never need to touch the command line to use it – but of course we do include all the necessary command line tools and header files for advanced users.
Postgres.app can install minor updates automatically, so you get bugfixes as soon as possible.
Download ➜ Move to Applications folder ➜ Double Click
If you don't move Postgres.app to the Applications folder, you will see a warning about an unidentified developer and won't be able to open it.
Click 'Initialize' to create a new server
Configure your $PATH to use the included command line tools (optional):
Done! You now have a PostgreSQL server running on your Mac with these default settings:
| Host | localhost |
| Port | 5432 |
| User | your system user name |
| Database | same as user |
| Password | none |
| Connection URL | postgresql://localhost |
To connect with psql, double click a database. To connect directly from the command line, type psql. If you’d rather use a graphical client, see below.
NOTE: These instructions assume that you’ve never installed PostgreSQL on your Mac before.If you have previously installed PostgreSQL using homebrew, MacPorts, the EnterpriseDB installer, consider removing other PostgreSQL installations first.We also have instructions for upgrading from older versions of Postgres.app.
Postgres.app includes psql, a versatile command line client for PostgreSQL.But it’s not the only option; there are plenty of great graphical clients available for PostgreSQL.Two popular tools are:
pgAdmin 4 is a feature rich open source PostgreSQL client.It has support for almost every feature in PostgreSQL.The only downside is that the cross-plattform UI really doesn’t live up to the expectations of a native Mac app.
Postico on the other hand, is a very modern Mac app.It’s made by the same people that maintain Postgres.app, and we think you’ll like it! We put a lot of effort into making it a joy to use.However, it doesn’t have the extensive feature set of pgAdmin, and it’s a commercial app rather than open source.
Aside from those two options, there are a lot more to choose from! Check the documentation for a list of amazing Mac apps for PostgreSQL.
After your PostgreSQL server is up and running, you’ll probably want to connect to it from your application.Here’s how to connect to PostgreSQL from popular programming languages and frameworks:
To connect from PHP, make sure that it supports PostgreSQL. The version included with macOS doesn't support PostgreSQL. We recommend MAMP for an easy way to install a current version of PHP that works.
You can use PDO (object oriented):
Or the pg_connect() functions (procedural):
To connect to a PostgreSQL server with Python, please first install the psycopg2 library:
In your settings.py, add an entry to your DATABASES setting:
When using the Flask-SQLAlchemy extension you can add to your application code:
To install the pg gem, make sure you have set up your $PATH correctly (see Command-Line Tools), then execute the following command:
In config/database.yml, use the following settings:
Alfred (OS X) Alfred is a combination app launcher and desktop/web search utility for OS X. Mac App Store Mac App Store is the simplest way to find and download apps for your Mac. To download apps from the Mac App Store, you need a Mac with OS X 10.6.6 or later. Click the magnifying glass icon once (or press the Command key+Spacebar), and the Spotlight search box appears (see the following figure). A lot of power purrs behind this single Spotlight search box. To run a search, simply click in the Spotlight box and begin typing. (The words you type that you want to match are keywords.). /computer-searching-app-mac.html.
What's the newest recording app for mac reviews. In config.ru or your application code:
Install the activerecord gem and require 'active_record', and establish a database connection:
Install and require the datamapper and do_postgres gems, and create a database connection:
Install and require the sequel gem, and create a database connection:

libpq is the native C client library for connecting to PostgreSQL. It's really easy to use:
Now compile the file with clang and run it:
You can just use the C API in Swift! First include libpq in your bridging header:
Then make sure to link with libpq.
On iOS, you'll need to build libpq yourself.
On macOS you can use the system provided libpq (does not support SSL) or use libpq provided by Postgres.app by adding the following build settings:
| Other Linker Flags | -lpq |
|---|---|
| Header Search Paths | /Applications/Postgres.app/Contents/Versions/latest/include |
| Library Search Paths | /Applications/Postgres.app/Contents/Versions/latest/lib |
Now you can use the libpq C library to connect to PostgreSQL:
We have a list of common problems in the troubleshooting section in the documentation.
For general questions concerning PostgreSQL, have a look at the official PostgreSQL documentation.
If you have a question concerning Postgres.app that is not answered by the Postgres.app documentation,you can ask @PostgresApp on Twitter, or open an issue on GitHub.
When reporting bugs, let us know which version of Postgres.app & macOS you are using, and be sure to include detailed error messages, even if your issue seems similar to another one.
