Straightforwardly: Which _model_ Macbook is it? [About this Mac under MacOS] If you run hwinfo under Debian- what does it say? If you run cpuinfo under Debian - what does it say For Macs of this vintage: (2006/2007 Core 2 Duo) iMac 5,1 – iMac 5,2 – iMac 6,1 Macbook 2,1 MacBook Pro 2,1 – MacBook Pro 2,2 Mac Pro 1,1 Xserve 1,1 (maybe) They have a 32 bit EFI and a 64 bit processor. You might want to try with the Debian multi-arch CD which might sort it out. https://cdimage.debian.org/debian-cd/current/multi-arch/iso-cd/debian-10.10.0-amd64-i386-netinst.iso or, in exceptional cases for only a couple of models: https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-mac-10.10.0-amd64-netinst.iso If you only have a small amount of memory, you may want to consider that running virtual machines / Docker may be quite frustrating. Hope this helps All the very best as ever, Andy Cater
