The Sibelius Forum

Would anyone know why it's taking Sibelius over 6 minutes to open? Don't remember when this started and that's why I don't shut Sibelius down to often. My Mac computer has 16 gig of ram which is the maximum I can put in there.

Which Mac OS is this? The problem is that when something goes wrong with a Mac, there is less that can be done. Is Sibelius the only software you are having trouble with? If so, that's good. I suggest closing Sibelius (yeah, I know), and shutting down the computer. Not just restarting it. Let it think about it's sins for a few moments. Then start it up. Go to Utilities. Depending on how old you OS is, you'll either have a utility called First Aid, or something to restore permissions. Run that. Then restart the computer and try Sibelius. If that doesn't work, try starting Sibelius from the applications folder rather than the desktop. Good luck.

The Mac that I have is running on High Sierra 10.13.6. Sibelius is the only program I'm having this problem with. I tried everything you suggested and still the same problem. Sibelius took 6 minutes to open.

Any updates to things like audio drivers, or Mac updates that might have messed things up?

I don't know where I would need audio drivers, never had a issue with those before and my Mac is up to date. The only thing that works for me is that I turn off and on my computer about every two weeks. That's the only time when there is an issue with Sibelius. When my computer is on, Sibelius is always on, so it's not a real big issue. Anyway thanks for you input.

So the next time you start Sibelius, watch the splash screen. Down in the lower left corner there is dialogue that tells you what Sibelius is loading. Tell us what process is loading when it stops on one for a long time. Might be more than one. It shouldn't spend more than a second or two on anything.

Checked the splash screen and Sibelius is stuck on "Creating Main Menu". It's been over ten minutes and it's still now open. It never took this long. Just tried opening Sibelius from the applications menu and it did nothing at all, no wheel spinning, nothing. I have an older version 7 that I tried to open and that wouldn't open either.

Try disconnecting from the internet, restart our mac, then start Sibelius.

A long shot, but Sibelius does two things on line when it starts. It checks to see if it is activated and if it needs to up date. A problem with either of those services could slow down start up. I'd know more on a PC. Some folks have had problems with the activation manager.

I tried your suggestion about disconnecting form the internet etc. and no different results. Sibelius is still reacting the same way. Thanks for you trying to help. I guess I'll have to live with this until something changes.

...and you are starting the 64 bit version and not the 32 bit version.

I don't know about Mac, but Windows can attempt a repair install. It's also possible to just reinstall Sibelius.
