Paint Tool Sai For Mac 10.11

Xquartz

Here is a suggestion from my friend about another nice paint tool named Pro Paint for Mac which can paint, draw, edit image, vector graphic design, free-form transformation, add filters, crop, alpha channel edit and more like paint tool sai. It supports el captitan. However, the downside to Paint Tool SAI is that it can only be run on Microsoft Windows®, thus forcing Mac® users to find alternative solutions.

Paint Tool Sai

Hello! Like the title says, I would really love it if there was SAI for Mac or an alternative.
I've tried these programs:
- Photoshop
- Corel Painter
- ArtRage
- SAI through Wine / MikuInstaller
- Pixelmator
- Seashore
- GIMP + GIMP Painter
- MyPaint
- Autodesk Sketchbook + Copic Edition
and a lot more that I can't remember. All of those, though, just didn't work like SAI.
I used Clip Paint Lab and Clip Studio Paint until they expired, and I can't get the money to pay for Clip Studio Paint... Those programs were the closest I've ever found, though.
My dad won't let me install Windows through VMWare or Parallels. Crossover has no pen pressure, and I just can't find anything else.
I've tried Bianca-Jo, but her blog was taken down... She recently posted about it (in April....) but no updates since then.
I'm trying to be really specific, I want something for Mac that works as well as SAI.
Please, is there any program out there that would work for me? SAI is for mainly manga/anime artists, and since that's my main style, it would be great if the program were along those lines.
Thanks!
