# bundle app from trial

It doesn't work anymore. 404 on the trial url. tried the newest trial version but that ends up in a broken app

For me it worked with https://www.aseprite.org/downloads/trial/Aseprite-v1.3.14.1-trial-macOS.dmg. Pay attention to change the version also in the hdiutil attach command
hdiutil attach -quiet -nobrowse -noverify -noautoopen -mountpoint mount Aseprite-v1.3.14.1-trial-macOS.dmg

There is EULA need to be accepted.
This will bypass EULA:

hdiutil convert foo.dmg -format UDTO -o bar.cdr
hdiutil attach bar.cdr ---> it will mount to /Volumes so no need sudo/permissions, no need create mount folder

Great contribution. I’m working on a project to substitute this gist. Today this gist is obsolete. My goal is to make a multi platform compilation script to make Aseprite in Windows, macOS and Linux.
