iMovieHD-iDVD combo

[hughmichael]

Unable to find quality replacement for the old iMovieHD-iDVD combo, and HighSierra will not run the software.
Can I reinstall old OS, and abandon the newer OS versions?
Required for project. Very important.

Can I reinstall old OS, and abandon the newer OS versions?

Only if you have a Time Machine or other backup and are willing to erase your drive and reformat so that it will run that OS.

Options:

1) Boot from an external with the older OS if you can. With most Macs, this will be slower but no reason why it won't work. Many of us have drives so formatted for that reason. To boot back into HS, you will need to Option Boot.

2) Purchase Final Cut Pro.
