I recently upgraded to Ghostscript 10 and GMT6.4 and now I cannot see transparency in jpg plot converted with psconvert. I use a old syntax of gmt in a csh script. From the output of psconvert with -V seems all in order, but I cannot see the transparent symbols in the jpg. I use a MacBook Pro with BigSur 11.6.1 Thank you in advance for your help. ---

I have not tried gs 10.0.0 since the latest I see on mac ports is 9.56.1 but from past history gs has a way of screwing up transparency every few releases. We will need to see if we can reproduce it. ---

I was strongly suspecting of that as the GMT.jl documentation lost the transparency in all examples that use it. Very annoying this frequency at which gs fscrews. ---

Will be there any attempt to fix this or any tip on how to fix myself? Thank you in advance! ---

Simplest “fix” is to move back to gs 9.56.1. @Joaquim, we need a tiny example that fails with 10 but works with 9.56.1 if we are to post on the gs bugzilla site. ---

I’m using a MacBook Pro with Monterey 12.0.1 and I’m facing the same issues. How do I downgrade from gs10 to gs9.56.1? Is there any brew formula for that? ---

I am sure there is a standard way. I am using mac ports so cannot help. Maybe @seisman knows? ---

If you’re a Homebrew user, you can: 1. Download the formula for ghostscript v9.56.1 ([https://raw.githubusercontent.com/Homebrew/homebrew-core/4e4d823cba1ba5d139113ae61200567956da8c7e/Formula/ghostscript.rb](https://raw.githubusercontent.com/Homebrew/homebrew-core/4e4d823cba1ba5d139113ae61200567956da8c7e/Formula/ghostscript.rb)) to your computer 2. Uninstall you ghostscript v10.00.0 by running `brew uninstall ghostscript` 3. change into the directory where you downloaded the old formula `ghostscript.rb`, and run `brew install ./ghostscript.rb`. `brew` will use the formula in the current directory by default. ---

I have the same problem, thanks for the tip… I followed the procedure but in my case Homebrew always fetches the \*.rb formula of the 10.00.0 version thank you for helping ---

Sorry. The last step should be `brew install ./ghostscript.rb` instead. I’ve revised my answer above. ---

I should have thought myself…sorry…It totally worked and transparency are back. Thank you very much! ---

I apply this method but brew still upgrades it to gs10. I found out that while uninstalling gs10, gs9.56.1 was still in the root. I did brew doctor and even brew link, but getting this message “psconvert [ERROR]: Cannot execute Ghostscript (gs)”. How could I fix that issue? ---

What happens if you just type `gs` in your terminal? Or type `which gs` to see its full path. ---

I’ve fixed it by uninstalling the existing gs9.56.1 and running later on brew install ./ghostscript.rb. It works now. Thank you! ---

Turns out this was actually a GMT problem (we did not check for gs version numbers \> 9). A [PR](https://github.com/GenericMappingTools/gmt/pull/7096) has been merged into master that fixes the problem on our side and now gs 10 works fine with GMT master.
