So, if I had a PDF with 12 pages (2 slides for each page) I will expect a new PDF with 24 pages (1 slide for each page).

Open your pdf in Preview.app. Click the toolbox icon. Click the Rectangular-Select icon. Select one of the pages. Copy it. Click File > New from clipboard. Save that file. Repeat. Now you have Untitled1 through Untitled24. Open Untitled1 in Preview. Click the menu just under the red x and choose "Thumbnails." Drag all the files Untitled2-24 just under Untitled1 in the sidebar. Save as a pdf.
