Jedit Ω 

Must-have Tool for General Text Processing

J macOS11 Web256

One of the most popular text editor Jedit X has re-born into an entirely new editor Jedit Ω. All functions were reviewed and refined. It supports the latest macOS features such as iCloud, Version Control, Auto Saving, etc.

❏ To old Jedit X users
As Jedit X is a 32bit application, macOS10.14 (Mojave) will be the last macOS on which Jedit X can work. We recommend to upgrade Jedit X to Jedit Ω.

To suppress the Jedit Ω upgrade alert that are shown every 10 days, set the option “Check for updates every 10 days” to OFF in the Preferences “Gerenral>Advanced.”

❏ App Store edition and Web edition
You can download Jedit Ω from either the App Store or this site. Both edition are available from free (the free version is still a fully featured as a basic text editor).

You can upgrade Jedit Ω to the full functional version, App Store edition with an in-app purchase, and the web edition from the shop on this site.

<The difference between App Store edition and Web edition>
The App Store edition has dark red application icon and the Web edition has black application icon. All  functions of both editions are same. However, as the App Store edition works on the Sandbox environment, its security is high but it has some restrictions such as not being able to access an external file by direct path name from AppleScript.
If I dare to say that there is not a big difference in either version, I recommend the AppStore version if you choose it by the ease of update as same as  other AppStore applications, and the Web version if you think mainly about the use of macros such as AppleScrip.

❏ System Requirement      

macOS 10.10 (Y0semite) or  later.
macOS 10.12 (Sierra)  or  later is recommended.
functions such as Split Views or Tool bar are not supported on macOS 10.10/10.11.
