AIJ installation is currently not directly compatible with OS X 10.12,10.13, 10.14, or 10.15+, but there is a new Java 8-based AIJ build thatsignificantly simplifies AIJ installation. The new version only supports 64 bitMac OS, so older Macs will need to continue to use the Java 6 installation.

Follow these steps to install the newer AIJ Java 8 version:

1) Download the latest AIJ Mac installation zip file that is labeled with'java8'.

2) Double-click the installation file to decompress the app to'AstroImageJ'.

Jun 17, 2020 ImageJ can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images and supports most major formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and 'raw'. The main use of ImageJ is that it can calculate area and pixel values which may be useful for graphic designers.

  • ImageJ runs in 32-bit mode using Java 1.5 (Java 1.4 on OS X 10.3) and ImageJ64 runs in 64-bit mode using Java 1.6. ImageJ64 is not limited to 1800MB of memory but it requires a 64bit Intel Mac running Mac OS X 10.5 or later. The - 'AstroIJMacx.x.x.zip' file can be deleted.

5) Double-click the AstroImageJ app and it should now open with no errormessages.

6) Go to AIJ_Toolbar=>Edit=>Options=>'Memoryand Threads' and update the 'Maximum memory' value from thedefault 3000 MB to your preferred AIJ memory upper limit. It is recommended toset the value to ~75% of your computer's physical memory. For example, if youhave 8 GB of memory, set the maximum memory value to 6000 MB.

7) Close and reopen AIJ to activate the new memory setting. Click on thebottom of the toolbar to verify that the new memory setting is retained, andverify that Java 1.8 is indicated. If so, you should be ready to use AIJ.

8) Use the AIJ Update feature at AIJ_Toolbar=>Help=>UpdateAstroImageJ to update to the latest numbered release or the daily build. The'Upgrade To:' box will default to the latest daily build version ofAIJ. If you prefer the latest numbered release, select it in the dropdown box.Click 'OK' and three files will be downloaded and installed in theproper location in the installation directory structure (you need write accessto the installation directory). After the files have been installed, AIJ willautomatically close. Restart AIJ to use the updated version.

Your AIJ installation should now befully functional. STOP HERE.

If the older Java 6 version is required for installation, you will need tofollow the more complex workaround steps described below.

There are currently two procedures that are tested to work with 10.14 andolder, but jump to the separate section below for 10.15+ installation. Thesimplest only requires a command to be executed in a terminal window once thepackage is installed:

  1. Download the latest mac installation file.
  2. Unzip the installation file and move the AstroImageJ folder to the Applications folder
  3. Run this command in Terminal


xattr -r -d com.apple.quarantine/Applications/AstroImageJ

Mac


That's it! AIJ should now start up normally. If it does, then follow theinstructions below in the section labelled 'Post Installation'. Thereis no need to run both methods. We expect the first one will work for mostusers. If not, you could try this previous workaround that is a bitmore complicated and requires superuser login.

  1. If you haven't already, Install AIJ by unzipping the install file and dragging the resulting AstroImageJ folder to the Applications folder.
  2. Open the Terminal app from the /Applications/Utilities/ folder and then enter the following command syntax: sudospctl --master-disable
  3. Hit return and authenticate with an admin password.
  4. Relaunch System Preferences and go to the Security → Privacy → General tab.
  5. You will now see the Anywhere option under Allow apps downloaded from:. Select this option.
  6. Make a copy of /Applications/AstroImageJ/AstroImageJ64.app on the desktop. An easy way to do that is hold down the alt key while dragging AstroImageJ64.app from the /Applications/AstroImageJ folder to the desktop.
  7. Delete the original copy of AstroImageJ64.app that is still in the /Applications/AstroImageJ folder.
  8. Drag the copy of AstroImageJ64.app from the desktop back to the /Applications/AstroImageJ folder.
  9. Start AIJ and set up your memory settings as needed.
  10. Close AIJ.
  11. After running AIJ the first time, enter the following command syntax to reenable GateKeeper (AIJ will continue to work normally): sudospctl --master-enable

Post Installation: After installation you should change the upperlimit on the amount of memory that is available to AstroImageJ and check forAstroImageJ updates. Both of these can be done at any time, and the updateswill keep your installation current with bug fixes and new features.

  • The default upper limit on memory available to AIJ is 640 MB. This will need to be increased in order for AIJ to run properly. Change the upper limit on the amount of memory available to AIJ using AIJ_Toolbar->Edit->Options->Memory & Threads. Enter the amount of memory in MB. It is recommended to set up about 2/3 of the physical memory installed in your system. For example, if your machine has 8 GB of memory, enter a memory size up to ~5500 MB. Note that this memory setting is an upper limit. AIJ uses only the amount of system memory that is needed at any one time.
  • Click 'OK' and close AIJ. Restart AIJ to use the new memory settings.
  • Finally, upgrade to the latest version of AIJ by using the built-in update feature. Go to AIJ_Toolbar->Help->Update AstroImageJ. The 'Upgrade To:' box will default to the latest version of AIJ. Click 'OK' and three files will be downloaded and installed in the proper location in the installation directory structure (again, you need write access to the installation directory). After the files have been installed, AIJ will automatically close.
  • Restart AIJ to use the updated version.

On the Mac with this installation procedure AIJ can be started bydouble-clicking either the AstroImageJ.app or theAstroImage64.app icons. Either app can be dragged to the Dock to provideconvenient access for starting AIJ.
