Thanks for the instructions – I had to make a few adjustments to get the latest 10.15.7 Catalina to shove itself into an.iso – Remove OS X everywhere and replace it with macOS, and then make the second.cdr bigger. Purchase a retail copy of Mac OS X Snow Leopard ($30 from Apple) 2. Purchase a replacement set of system discs - but you'll need to call Apple and explain that you purchased a used machine without system discs and need replacements.

One Small Step (a Bird) Mac Os Update

I could be wrong here, but I don't think that you could get it on anything smaller than an 8GB flash drive.
I pulled up my system folder which weighed in at 1.36GB, but my Library was over 6GB. Then there would be the utilities and those were 130MB or so.
I remember that you needed to partition the hard drive on older Macs to get them to dual boot OS X and OS 9. It was possible to get it all on an 8GB partition.
Flash drives of that size are running almot $200. While it would certainly be very cool to whip one out in an emergency, I think a USB/FW hard drive would be a better investment.
Just my opinion...
