I am running this on an Apple.Machine Name: Mac miniMachine Model: PowerMac10,1CPU Type: PowerPC G4 (1.2)Number Of CPUs: 1CPU Speed: 1.25 GHzL2 Cache (per CPU): 512 KBMemory: 512 MBBus Speed: 167 MHzBoot ROM Version: 4.8.9f11.) The software that came with it failed to do unattended shutdown.I am told that native support might work.2.) There are no patches or newer software on APC website, for easy download.Support did not seem to know of any patches. That is the cardinal sin for me.3.) If you need unatended shutdown you are better off with a good surge protector, APC software may puts your system at risk.4.) If you need very short term UPS with surge protection it might be your ticket.Price is correct, but I do not like products that say they do something and do not.
