• Mar 13, 2013 - 18:13

I tried to download Version 1.3 for Snow Leopard and after downloading got a message saying that I could not open version 1.3 because "it won't work on this Mac". Here are the specs on my Mac:

Model Name: MacBook Pro
Model Identifier: MacBookPro1,1
Processor Name: Intel Core Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 2 MB
Memory: 2 GB
Bus Speed: 667 MHz
Boot ROM Version: MBP11.0055.B08
SMC Version (system): 1.2f10
System Version: Mac OS X 10.6.8 (10K549)
Kernel Version: Darwin 10.8.0
Boot Volume: Macintosh HD

Any ideas why I can't open the new version?
Thanks for any help you can offer with this.


Your macbook pro has an old processor (Intel Core Duo). MuseScore 1.3 doesn't support this processor anymore. You can install MuseScore 1.2. The two last versions of OS X (Lion and Mountain Lion) are not supported on this processor either.
