M1 Macs and LC 9.6.8 RCs and 10.0.0 RCs

[Niggemann, Bernd]

Sorry if this has been discussed before but I could not find it.

Yesterday I played around with LC 9.6.8 RC2 and 10.0.0 RC4 and wanted to see what difference the new Universal build does for speed.

After some testing I finally read the release notes and it states:
Note: Apple architecture support is currently experimental. To run the IDE using Apple architecture (on supported machines), you must toggle the Open using Rosetta option to off in the LiveCode.app bundle's Get Info pane in Finder. To build a standalone with native Apple architecture support you must explicitly choose the macOS Apple option in standalone settings.

For me the "Rosetta" box was not checked out of the box but LC ran in Rosetta mode.
Which means by default in the "Get Info" for the app "Use Rosetta" is unchecked but LC runs using Rosetta. You have to check "using Rosetta" and then right away uncheck "using Rosetta"
>From then on LC uses arm64.

I noticed some nice speed increase across all aspects of using LC: what used to take 10 seconds now takes 6.5 seconds. That is not bad for checking a box.

Kind regards
Bernd
