4. Enlarge the writable DMG, by first checking the current size: `hdiutil resize template_dmg_rw.dmg`, e.g. you get 430000 in the 'cur' column, then just resize it to e.g. 500000: `hdiutil resize -sectors 500000 template_dmg_rw.dmg`
5. Mount the DMG: `hdiutil attach template_dmg_rw.dmg`
6. Open the OpenRocket-disk from your desktop and change the app name from 22.02 to 23.09
7. Copy the .DS_Store to `openrocket/install4j/23.09/macOS_resources` by running the command `cp /Volumes/OpenRocket/.DS_Store openrocket/install4j/23.09/macOS_resources/DS_Store`
