Installing High Sierra on new MacBook Air
Installing High Sierra on new MacBook Air
I've legacy software (Filemaker Pro) which doesn't work on Mojave, but does work on High Sierra.
I booted the MacBook Air [MBA] in Target Mode (I see the thunderbolt and USB icon) but when I use the Thunderbolt 3 cable to connect the new MBA to my MacBook Pro (running Sierra) it doesn't appear.
I've also tried booting from an external drive running Sierra and get a message saying MBA (or perhaps Mojave on MBA) doesn't support booting from external drive.
I'm comfortable reformatting drive and installing the High Sierra OS but want to make sure I can access the new MBA before doing so.
Perhaps it's a different between the HFS and APFS file structure.
Likely something obvious for me to do ... but I'm baffled.
Thanks for your help!
