Aperture, Resolution
Where can I check and change the resolution in Aperture?
//Tommy
Aperture uses the display(s) resolution(s) you specify in "System Preferences→Displays".

Sorry, I actually mean the resolution of a picture. Where can I check the actual resolution and change it (like in Photoshop)
Resolution is device-dependent and is expressed as a ratio of image units per standard unit of length (and usually assumes a 1:1 aspect ratio for the image units).
Images in Aperture have pixel dimensions (in absolute pixels; devices map those pixels to physical dimensions of length). You can crop an image in Aperture (throw out any of the available rows or columns of pixels starting in from either the top, bottom, or either side), but you cannot remap the existing pixel grid to a new pixel grid within Aperture. To do so you need to create a new file (which is what exporting does). If you want that file to be in your Aperture Library, you will have to import it. (Such a workflow is rarely efficient.)
Isn't what you want to accomplish best done at export? (In which case you would specify the image-format file's pixel dimension using one of the Export Presets.)
The pixel dimensions are part of the metadata. Metadata can be shown in any of the seven Metadata Overlays, and also in any of the Metadata Views that show on the Metadata tab of the inspector:
