Greek Spell checker on mac

Dear all,

since I didn't find a complete answer in any link, I will create my own reply

• Search your preferred language file (e.g. Greek) in thsi link: https://extensions.openoffice.org/en/search?f%5B0%5D=field_project_tags%3A157
• Download the "some.oxt" file on your mac
• Rename the "some.oxt" file to "some.zip"
• Unzip the file (to unzip it, right-click and "Open" it)
• Look for two files: "lang.aff", "lang.dic
• copy them in your Home/Library/Spelling folder (to find tthis folder, open "Finder", and at the top-up menu on your screen click on "Go" while you are pressing the "option" key. Then, a new option will appear above "Computer" called "Library")
• After you copied the two files in your spelling folder, restart your computer and everything will work just fine
