I've been running System 7 using SoftMac that emulates a vintage Macintosh Quadra 650. I found a System 7 disk image online, along with a Quadra .ROM file. I've never used System 7 until now, and I'm a noob when it comes to emulation. There seems to be some apps missing in the control panels. I found a bunch of control panel apps in the "Preferences" folder, but they are all locked by the system. Take a look at the screenshots below. I've been trying to change my desktop wallpaper, but I can't. Also, every time I try to import an image on a floppy, System 7 can't read it. Again, I'm a complete noob to System 7. Could someone help me?
