About MacOs future with ARM

Hi Julien,

Good questions IMHO.

>From what I read yesterday, Apple would propose a "Rosetta 2" on-the-fly
byte-code conversion environment to allow programs compiled for x86
hardware to continue running for a while at least to ease the transition.

For those of us having been (un)fortunate or old enough to have lived
through the first iteration of Rosetta, when Apple transitioned from PPC
to x86 they will know that performance will take a significant hit,
memory consumption will likely go through the roof, and that some stuff
just won't work...depending on how well Apple implements Rosetta 2.

Then comes the question of whether, indeed, the project has the
resources to provide 2 ongoing versions of LO for macOS for 2 different
chip architectures...

Will be interesting to see how this evolves.

Alex
