Can existing data from Oscar 1.7 be imported into Oscar 2.0 - to allow a single view for past and present data?

[Mijjil]

Yes, when you run OSCAR 2.0 it will ask you where your 1.71 data lives and will import it.

[mpeg2]

Importing from 1.7 is good - but: I'm a Mac user - and see on the Mac install page that it was compiled for Intel CPUs - Apple Silicon requires the use of Rosetta. As far as I can see, this was not the case for 1.7. Looking a little deeper, I saw that Rosetta is going away in the not too distant future.

Any chance of getting a version compiled for Apple Silicon??

Thanks,
Rich

Our problem is that we don't have a developer with a Mac Mx computer. That's all that's missing. OSCAR is an all-volunteer project and we need a volunteer developer with the necessary hardware. We thought we had one for a while with 1.7 but he is MIA so we were unable to make a Mac Silicon distribution package for OSCAR 2.0. We keep looking for someone who can help but the volunteers we have seen recently use either Windows or Linux. Or maybe someone will gift us with an old Mx and we could use that to build OSCAR (wishful thinking).

Yes, when you run OSCAR 2.0 it will ask you where your 1.71 data lives and will import it.

Really appreciate the effort that goes into these releases. Having been a software release engineer in another life, I understand the issues.

Have a mac desktop here. OSCAR 2.0 couldn't copy the data from the external disk where I had OSCAR 1.6 saving my sleep data. I could copy the data files from the external disk to the internal one temporarily, but I'll probably just leave the old data where it is and access it with OSCAR 1.6 if I need to.

I also noticed the reference to Apple discontinuing the support of Intel-based apps during installation and when I run it. Hopefully you'll get a chance to build OSCAR on a mac before Fall, 2027.

Again, thanks so much for all that you do!

"Our problem is that we don't have a developer with a Mac Mx computer..."

I understand the problem now and wish I could help out - but the last time I did any code development was probably 30 years ago on what are now completely archaic systems.

For the time being, the old version of OSCAR works fine for me.

I do appreciate all the effort that is going in here.

i really like the new functionality with exporting. However, I have no idea how to edit the SQL or even where to look for guidance. Is there a tutorial page/document available?

For how to use the Export to CSV dialog: https://www.apneaboard.com/wiki/index.p ... _OSCAR_2.0

Not sure where to find a tutorial on SQL query language. Anyone have a better suggestion than just googling it?

Thanks to an Apnea Board member, an installer for Mac Silicon is now available on https://sleepfiles.com/OSCAR

Thanks so much for this...an alternate way to run the app on a mac the first time is to go into System Settings -> Privacy and Security and enable "run anyway" for OSCAR20. A little simpler if you know your way around Settings :-).

Not knowing what would happen if I installed OSCAR20 on top of OSCAR20, I removed the Intel version before installing the Apple silicon version...seems to have worked.

Thanks again, glad that you got this done so quickly!

[mpeg2]

Thanks - amazingly fast...
