iMovie supports Mac Pro2015 model or not ?

Your MacBook Pro would originally have been shipped with iMovie , so yes your Mac will support iMovie.

If you bought it new then iMovie will be in your Applications folder, unless it has been deleted.

Are you having problems opening the iMovie Application?

If you are having problems, then it may be that you have upgraded your OS but have not updated your iMovie to remain compatible.

To be sure it would be useful to know what version of OS you are running and the version of iMovie you have in order to determine if they are compatible.It may be that you need to update iMovie.

To find out the OS, click on the Apple logo top left of screen and select " About This Mac"

This will tell you what OS you are running.

For iMovie go to your Applications folder and Control click ( right click) on the iMovie Application and select

'Get Info". In the pop up you can see the version number of iMovie.

If you get back here with this information someone may be able to help if you are still having problems.

Yes, just ensure you’re running the latest version of macOS (which the MBP 2015 supports).
