Q: PPC on Yosemite ?

Bonjour,

actuellement j'ai un iMac 24" sous Lion plus un DD SSD externe sous Snow Leopard avec de vieux logiciels PPC nécessitant Rosetta.

Tout fonctionne parfaitement, je peux redémarrer sur l'un ou l'autre.

J'envisage de passer mon iMac de Lion à Yosemite (ou El Capitan), ça me permettrait d'utiliser des logiciels plus récents ou de mettre à jour mes logiciels.

Ma question :

Le disque dur externe sera-t-il opérationnel (le fait que Yosemite ou El Capitan ne comportent plus Rosetta empêchera-t-il les logiciels PPC de mon SSD de fonctionner) ?

Merci.

 

Hello,

currently I have an iMac 24 " running on Lion plus an external SSD HDD running on Snow Leopard (with old PPC softwares requiring Rosetta).

Everything works perfectly, I can restart on either.

I plan to upgrade my iMac to Yosemite (or El Capitan), it would allow me to use recent software or update my softwares.

My question :

Will the external hard drive be operational (Yosemite and El Capitan without Rosetta forbid my SSD PPC softwares to run)?

Thank you.

iMac, Mac OS X (10.7.5)

    PowerPC applications require the Rosetta technology that was last provided in OS X 10.6.8. Without Rosetta, your PPC applications are dead.

     

    Provided that your iMac 24 is recent enough for El Capitan hardware compatibility, and can also boot Snow Leopard, then you could dual-boot between Snow Leopard (your external Snow Leopard SSD with PPC applications), and El Capitan. I would not recommend less than 8GB of RAM on older hardware for El Capitan. It can be done in 4GB RAM, but performance will suffer.

    While you will be able to run the newer versions of OS X (assuming the Mac is new enough to support them) as well as Snow Leopard, choosing which OS to run next in System Preferences>Startup Disk won't work when you're in Snow Leopard and you want to switch to the newer OS because the newer OS won't be listed in Startup Disk. To get from Snow Leopard to the newer OS, you'd need to restart and hold down the Option key at the chime which invokes the Startup Manager. The newer OS will appear there so select it to continue booting. Note that Snow Leopard will still be considered the preferred startup OS unless you change it in Startup Disk after booting into the newer OS where both OS's will be displayed.
