This is an example of updating the installer from 22.02.beta.05 to 22.02:
1. Make sure install4j is not opened
2. Download the OpenRocket-22.02.beta.05-macOS.dmg file
3. Make a read/write .dmg file using the terminal command `hdiutil convert OpenRocket-22.02.beta.05-macOS.dmg -format UDRW -o 22.02.beta.05_rw.dmg`
4. Enlarge the writable DMG, by first checking the current size: `hdiutil resize 22.02.beta.05_rw.dmg`, e.g. you get 430000 in the 'cur' column, then just resize it to e.g. 500000: `hdiutil resize -sectors 500000 22.02.beta.05_rw.dmg`
5. Mount the DMG: `hdiutil attach 22.02.beta.05_rw.dmg`
6. Open the OpenRocket-disk from your desktop and change the app name from 22.02.beta.05 to 22.02
7. Copy the .DS_Store to `openrocket/install4j/22.02/macOS_resources` by running the command `cp /Volumes/OpenRocket/.DS_Store openrocket/install4j/22.02/macOS_resources/DS_Store`
8. Eject the OpenRocket DMG disk from your desktop (important step)
