Logic Pro 10.7.4. and Big Sur

Yes, absolutely. I have 3 different versions on my main machine.

What I do is make a copy of my current Logic. Lets say yours is Logic 10.4.8, I then rename that COPY (the copy can be on the Desktop, on a backup drive etc) to 'Logic_10_4_8'

Then I update the version that's sitting in the Applications folder (as that's completely unchanged and has the original default name), so it'll go to 10.7.x but the name will be unchanged.

Then copy your backed up Logic10_4_8 back into the Applications folder and it'll happily sit next to the current version. Just run the version you want to use.

I have all the versions on backup drives going right back to Logic 8.

The only caveat to this is that Logic 10.4.8 can run under Big Sur, and I don't know if it can. If you're already running it under Big Sur then you're good to go.

Hope this helps.

You have to already have the lower version somewhere. Either on a backup, or making a backup before updating.

Before I do an update of Logic I will make sure I make a copy of my current version so that I can go back in seconds if needs be.

If Logic updates and you haven't made or got a copy of the older version it's very hard to get hold of that older version again.

That's why when I make a backup before updating, I rename the backed up Logic with the version number.

The Logic in the Applications folder with the default name will always get updated when you hit update. I never have auto update turned on for this reason.

Cool.

Leave 10.7.4 where it is. Don't change the name.

Apend the name of 10.4.8 with 10_4_8

Put 10.4.8 in the Applications folder .

Use whatever version you want by just opening whatever version you want.

Yes is the answer to your question.

Please answer these 2 questions directly so I can try to help more precisely:

1. What version is sitting in your Applications folder?
2. Do you have version 10.4.8 asa backup somewhere else?

OK, apologies... this is getting confusing now. Let's try another appraoch. 2 questions:

What version is sitting in your Applications folder?

Do you have version 10.4.8 asa backup somewhere else?

No problem. Sorry I got a little confused.

Glad we got to the bottom of it.
