Neither boots; moreover, inserting USB stick when boot manager is shown hangs system (it stops reacting to mouse/keyboard); if stick is inserted during boot it never gets as far as even showing boot manager. Alexander reported something similar for 2007 Macs. Stick is not detected even when inserted under OS X. MacBook runs 10.7 and reports that USB stick is not readable and suggests to iniitialize it; iMac runs 10.9 and simply ignores it (may be I do not know where to look). I tried two different USB and one of them boots fine here on Dell Latitude E5450 as EFI so I do not think both of them are defect. Of course, they are not of finest quality ... Same image as CD boots (I tried only MacBook but do not have reasons to think that iMac will not boot). It presents three choices - two EFI and one Windows. Windows ends up in presenting 1, 2 menu (without any additional explanation) and not accepting any input. This is known problem with legacy El Torito boot. First EFI boots; checking $cmdpath it boots from HFS+ partition. Second EFI does not boot and falls through to default boot order. When I try to chainload bootx64.efi manually (I have dual OS X/openSUSE on it) it actually boots fine. I /think/ it tries to load \EFI\Boot\boot.efi which is 32 bit only. I need to test with removed boot.efi and with fat image. I do not know if mkrescue image ever booted as USB on Mac. Alexander says it does on modern Mac; anyone ever tried it on earlier models?
