Fuzzy fonts in the alignment view on OSX Mojave (10.14.x)


Looking for the 'Launch Jalview' buttons ?

You need to download an installer to run Jalview 2.11.
You can still use webstart to access old versions of Jalview in the version archive

On OSX Mojave, you may notice that sequences and IDs in the Jalview alignment window are hard to read. To fix this, first:

1. Save your work and shut down Jalview

2. Open a Terminal window (use spotlight or the Launcher and type 'Terminal' to locate the Terminal App), and type:

 

  defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO

3. Start Jalview again and load an alignment to check that the fonts are now legible.

Thanks to Marcin for reporting this issue and testing the workaround via issues.jalview.org/browse/JAL-3134
