I recently updated to macOS Big Sur. There are always some growing pains when upgrading to a new operating system, and one problem I ran into was not being able to launch Oracle SQL Developer.
Need for speed most wanted 2005 save game 100 complete download. Download and install Oracle SQL developer – MAC OS X – All Go to and download the Oracle SQL Developer 3.2.2 (3.2.20.09.87) for MAC. Do not forget to accept the license agreement. Locate the tar file in the Downloads folder and launch the install. MacOS Big Sur A new macOS that welcomes the arrival of Apple Silicon and offers better integration with mobile platforms, along with fresh visuals and a host of other features Big Sur Cache Cleaner. I'm using macOS Big Sur and Oracle 11g. Before updating my mac, I usually opened SQL Developer in the terminal: docker exec -it oracle sqlplus But after the update, I got an error: OCI runtime exec failed: exec failed: containerlinux.go:349: starting container process caused 'exec format error': unknown.
The Problem
It seems like, somewhere in the upgrade, SQL Developer (or a configuration file somewhere) lost the location of the Java JDK, typically expressed as the JAVA_HOME environmental variable. This happened after my upgrade to macOS Big Sur. I tested this by opening my terminal app and typing echo $JAVA_HOME, which returned nothing. So, if my system didn't know where JAVA_HOME was, I didn't think SQL Developer probably knew, either.
I learned that SQL Developer should ask the user where the JAVA_HOME is located when they first launch the app, but it never did for me. I launch the app and nothing. It bounces once or twice in the dock and then nothing.
The Solution
The first thing I did, since I had been using Java JDK 8 previously, was download and install the Java JDK 11 runtime from Oracle's website. After I got that installed a simple edit to SQL Developer's product configuration file was all it took to get it running.
Open your terminal app and paste in the following command to navigate to the SQL Developer product config file:
One note here is that you may have to change the 20.2.0 to the version of SQL Developer that you are using, 20.2.0 is the currect version at the time of writing this.
Now that you are in the folder, type in ls -al to see the contents of the directory we are in. You should see a product.conf file. We need to edit this file so SQL Developer knows where the Java JDK is located.
You can edit the file in the terminal with nano by typing in nano product.conf if you are comfortable with that, or you can type open in the terminal and Finder will pop up a window so you can right click the file and open it with whatever text editor you want.
On line 20 of the file you should see some text that says # SetJavaHome /path/jdk. I created a new line under this and pasted in the following:
Make sure that the jdk-11.0.9.jdk is the same as what you downloaded and installed from Oracle earlier. Save the file and that is it! You should now be able to launch SQL Developer normally.
Whether you build websites, develop apps, or create tools for businesses, Mac is a brilliant tool for developers. Its Unix-based OS, the hardware reliability, and the quality of the display on MacBooks and iMacs are just a few reasons for the developers' loyalty.
List of 10 Best Mac Developer Tools
No surprise then that there are lots of great apps for macOS that specifically address problems faced by developers. Whether it's writing code, managing files, or turning HTML into beautiful animations, there's a tool for it on the Mac.
Here is the shortlist of our 10 favorite Mac apps all developers should use.
1. Create beautiful animations with Hype
Hype is a keyframe animation tool that allows you to create HTML5 projects for use on websites, in digital greetings cards, infographics or ebooks. In its simplest form, you can just hit Record and move elements around the canvas. Hype will then watch what you do, create keyframes on the timeline, and turn the whole lot into HTML5. You can trigger animations and transitions with Actions, and if you want to have complete control, the JavaScript editor lets you code custom functions.
2. Easily manage APIs with Paw
Paw allows developers to test and debug APIs. It features full interaction with REST services and the ability to create and test HTTP requests. API calls can be imported from Postman, cURL, and Advanced REST client. And when you're done, you can export them again. You can add descriptions and constraints to APIs, and call on a large set of inbuilt extensions, or create your own from scratch.
3. Master regex with Expressions
Need to write and test regular expressions? Expressions is the right tool for the job. With syntax highlighting to make the pattern easy to read and modify, and a regex reference sheet in case you need to remind yourself of the syntax it makes playing with regular expressions simple. It has a minimalist interface and a choice of dark or light modes, meaning it keeps out of the way while you get on with the work.
4. Write code faster with TeaCode
TeaCode is a dynamic, intelligent snippet library of expendable code snippets for any programming language. This developer's tool features to write code in any language, slots into your workflow, a lot of expanders ready to go and create your own expanders, quick entry and browsing.
Instead of typing the whole action, you can only put down the expander and it with unfold into a full section of code.
5. Seamlessly operate servers with Forklift
Moving files between servers, uploading them to web hosts, and editing them online are key tasks for many developers. Forklift allows you to do all that and more. Whether the server you need to connect to is FTP, SFTP, Amazon S3 or WebDAV, Forklift makes it easy. And, of course, it connects to SMB and AFP servers too. You can synchronize files between your Mac and a remote server, preview remote files and compare two files in different locations.
6. Swiftly debug your code with CodeRunner
With support for 23 languages out of the box, including Swift, Python, C++, and AppleScript, CodeRunner is an essential tool in any developers' arsenal. Edit and run code with a single click, set breakpoints, and step through code line by line to debug it. CodeRunner also includes IDE-level code completion, including fuzzy search, tab selectable placeholders, and documentation snippets.
7. Organize multiple databases with SQLPro Studio
If you need to work with multiple different SQL database types, SQLPro Studio is the ideal choice. It has support for MySQL, Microsoft SQL Server, PostgreSQL, MariaDB, and Oracle. As a native Mac app, it's faster and more reliable than Java-based alternatives and allows you to simultaneously select multiple tables, update table content, and compare query results.

8. Manage SQLite databases with Base
For developers with more modest SQL needs, Base should be the go-to solution. It's an SQLite database manager that makes it easy to create, search, and edit data. With its spreadsheet-like interface, it's straightforward to get to grips with yet allows you to edit everything from basic default values to complex foreign key constraints.
9. Write perfect Markdown with Marked
The right tool for developers who spend their time coding in markup languages, a good preview tool essential; and that's exactly what Marked is. Whether you write in Markdown, HTML, OPML or any other markup language, Marked allows you to see how the finished version will look before you publish.
You can carry on writing in your preferred text editor while using Marked to preview the finished document. It also comes with tools like spelling and grammar checking, tips for simplifying sentences, word count, and reading time.
