So I discovered that High Sierra seems to have some permissions problem with older versions of Mac OS X. I suppose this could be posted in that section, but I feel like I'd get more responses here. I just got a G3 pismo the other day, and I'm just trying to load it up with some old games and software. Most of which is already on my iMac G3 and G4. I connected the PowerBook to the G4 with the PB being the one in target disk mode, copied everything that I needed to it no problem. Fast forward to right now, I have it plugged into my Mac Pro with HS. The drives get info box is pictured, all the permissions options are greyed out. Unchecking the "Ignore ownership on this volume" makes no difference. The exact same thing happens with this Mac Pro and my iMac G3. I thought it was an isolated issue with my iMac because of the sata to IDE adapter I have in it, but being as this PowerBook does the same thing I think its a problem with High Sierra (figures). My MacBook with HS cannot write to them either. Does this happen to anyone else, and possibly have a fix? I need to get myself another firewire drive, I havent had one in years. But USB is next useless with all these USB 1.1 Power Macs lol. Both the G3s are running 10.4.11 and 9.2.
